This study investigates whether child second language (L2) learners can use syntactic information during the processing of sentences involving unbounded dependencies and how their processing patterns compare to those of child monolinguals and adult L2 learners. Through a self-paced reading experiment involving the numeral quantifier (NQ) construction in Korean, we tested participants’ sensitivity to agreement violations between a noun phrase (NP) and an NQ in local and nonlocal conditions. The results showed that a subset of child L2 learners who demonstrated target-like knowledge of NP-NQ agreement in an offline task spent a longer processing time in the NP-NQ mismatch than in the NP-NQ match condition, in both local and nonlocal contexts. These child L2 learners’ processing patterns were comparable to those observed in child monolinguals and adult L2 learners. These findings suggest that child and adult L2 learners rely on the same system of syntactic representations and processing mechanisms that guide first language processing.

There is a current ‘theory crisis’ in language acquisition research, resulting from fragmentation both at the level of the approaches and the linguistic level studied. We identify a need for integrative approaches that go beyond these limitations, and propose to analyse the strengths and weaknesses of current theoretical approaches of language acquisition. In particular, we advocate that language learning simulations, if they integrate realistic input and multiple levels of language, have the potential to contribute significantly to our understanding of language acquisition. We then review recent results obtained through such language learning simulations. Finally, we propose some guidelines for the community to build better simulations.

Norwegian embedded clauses give children two options for subject placement: preceding or following negation (S-Neg/Neg-S). In the adult language, S-Neg is the ‘default’ and highly frequent option, and Neg-S is infrequent in children’s input. However, Neg-S may be argued to be the structurally less complex. We investigate whether children are aware of the existence of both subject positions, and if they prefer the more frequent or the less complex position. Through an elicited production task with monolingual Norwegian children (N=33, age 3;1-6;1) we find that children in general overuse the Neg-S option, and we suggest that children have an inherent preference for the less complex position, due to a principle of structural economy. We also find that a group of children display U-shaped development, first using only S-Neg, then only Neg-S and finally S-Neg again, and we relate this to structure building and economy of movement.

The article explores the prosodic and kinesic aspects of three different ish constructions using corpus data from the multimodal NewsScape Library of International Television News. The results reveal that bound -ish with ‘approximate’ meaning is longer in duration, higher in pitch, and shows more pitch variability than bound -ish with ‘properties’ meaning. Free Ish is also longer in duration and shows more pitch variability but is also prosodically set apart from its linguistic environment. Furthermore, the different ish constructions prove to be associated with different sets of kinesic features, although none of these reaches a significant level in the statistical model. It will be argued that the prosodic aspects mirror the constructional status of ish, whereas the kinesic aspects may be used to support their different functions.

The relationship between the ways in which words are pronounced and spelled has been shown to affect spoken word processing, and a consistent relationship between pronunciation and spelling has been reported as a possible cause of unreduced pronunciations being easier to process than reduced counterparts although reduced pronunciations occur more frequently. In the present study, we investigate the effect of pronunciation-to-spelling consistency for reduced and unreduced pronunciations in L1 and L2 listeners of a logographic language. More precisely, we compare L1 and L2 Japanese listeners to probe whether they use orthographic information differently when processing reduced and unreduced speech. Using pupillometry, the current study provides evidence that extends the hypothesis about the role of orthography in the processing of reduced speech. Orthographic realization matters in processing for L1 and L2 advanced listeners. More specifically, how consistent the orthographic realization is with its phonological form (phonology-to-orthography consistency) modulates the extent to which reduced pronunciation induces additional processing costs. The results are further discussed in terms of their implications for how listeners process reduced speech and the role of the orthographic form in speech processing.

Variationist research has much to gain from deepening engagement with theories about place, defined as space imbued with social meaning. One challenge that variationists face is how to adapt the complex and multifaceted aspects of place orientation into a single measure that can be included in models of sociolinguistic variation. In this paper, I advocate for an ethnographic approach to place, providing an example from Greater New Orleans, where post-Katrina displacement has highlighted individual connections to place. Using an ethnographically informed multidimensional place orientation metric (MPOM), I examine two local linguistic features among speakers from the suburban town of Chalmette, Louisiana according to place orientation. Via statistical modeling and case study of individual speakers, I demonstrate the value of MPOMs in quantitative analysis of sociolinguistic variation, arguing for further theorization of place orientation in our research and providing a model for variationist sociolinguists interested in engaging more with place theory.

Williams syndrome (WS) is a rare genetic disorder, characterised at the cognitive level by a phenotypic pattern of relative weaknesses (e.g., visuospatial skills) and strengths (e.g., some linguistic and nonverbal reasoning skills). In this study, we performed a systematic search and meta-analysis on lexical-semantic processing in WS, an area of knowledge in which contradictory results have been obtained. We found 42 studies matching our criteria, and, in total, 78 effect sizes were included in the meta-analysis. Results showed that individuals with WS have worse lexical-semantic skills than individuals with typical development, whether matched by chronological or mental age. However, people with WS have better lexical-semantic skills than people diagnosed with other cognitive disabilities. Finally, vocabulary skills seem to be relatively spared in WS, although they present some difficulties in semantic processing/integration, semantic memory organisation and verbal working memory skills. Taken together, these results support a neuroconstructivist approach, according to which the cognitive mechanisms involved in lexical-semantic processing may be modulated, even when performance in some tasks (i.e., vocabulary tasks) might be optimal.

In masked priming lexical decision tasks in alphabetic or syllabic script languages, latencies are longer when a word target is primed by a higher frequency neighbor (e.g., blue–BLUR) than when primed by an unrelated word of equivalent frequency (e.g., care–BLUR) – an “inhibitory neighbor priming effect.” In contrast, Zhou et al. (1999) demonstrated facilitatory orthographic neighbor priming for two-character Chinese words (e.g., 华丽–华贵). However, Zhou et al. did not control for relative prime-target frequency, which has been shown to be important in experiments when examining languages with other scripts. In the present Experiment 1 word neighbor primes (e.g., 容易-容貌) produced an inhibitory neighbor priming effect when the prime was higher frequency than the target, paralleling effects in other script languages. In further experiments, paralleling those in other script languages, two-character targets primed by nonword neighbors (容待-容貌) or single constituent characters matching the target in either position (容-容貌) showed significant facilitation. These results suggest that lexical activation/competition processes for two-character Chinese words are reasonably similar to those for words in alphabetic/syllabic script languages.

Languages differ considerably in the way they encode motion. Previous research on motion encoding has paid much attention to inter-typological variation (i.e., variation between language types) and intra-typological variation (i.e., variation within language types), but less focus on intra-linguistic variation (i.e., variation within particular languages). To fill this niche, the current study compares actual motion and metaphorical motion in Standard Mandarin Chinese with a corpus-based approach. We ask whether the typological properties in actual motion extend to metaphorical motion. The results indicate that the answer is negative. The typological properties including lexicalization patterns and the distribution of semantic components vary by both event type (actual motion vs. metaphorical motion) and genre (fiction vs. non-fiction) within Chinese. The intra-linguistic variation can be explained by additional factors – the pragmatic context and the structural property of Chinese. These findings support a constructional proposal of the motion event typology, which is a more nuanced typology that expands the binary distinction between V-languages and S-languages. In this proposal, the consideration of the scalar dimension enables more explicit descriptions of variation within languages (shift left- or rightward on the scale) and more accurate explanations for these phenomena.

Classic psycholinguistics seeks universal language mechanisms for all people, emphasizing the “modal” listener: hearing, neurotypical, monolingual, and young adults. Applied psycholinguistics then characterizes differences in terms of their deviation from the modal. This mirrors naturalist philosophies of health which presume a normal function, with illness as a deviation. In contrast, normative positions argue that illness is partially culturally derived. It occurs when a person cannot meet socio-culturally defined goals, separating differences in biology (disease) from socio-cultural function (illness). We synthesize this with mechanistic functionalist views in which language emerges from diverse lower-level mechanisms with no one-to-one mapping to function (termed the functional mechanistic normative approach). This challenges primarily psychometric approaches—which are culturally defined—suggesting a process-based approach may yield more insight. We illustrate this with work on word recognition across multiple domains: cochlear implant users, children, language disorders, L2 learners, and aging. This work investigates each group’s solutions to the problem of word recognition as interesting in its own right. Variation in the process is value-neutral, and psychometric measures complement this, reflecting fit with cultural expectations (disease vs. illness). By examining variation in processing across people with a variety of skills and goals, we arrive at deeper insight into fundamental principles.

We investigated the predictive processing of grammatical number information through stem-vowel alternations in German strong verbs by adult first language (L1) speakers and Dutch-speaking advanced second language (L2) learners of German, and the influence of working memory and awareness (i.e., whether participants consciously registered the predictive cue) thereon. While changed stem vowels indicate a singular referent (e.g., /ε/ in fällt3SG, “falls”), unchanged vowels indicate plural (e.g., /a/ in fallt2PL, “fall”). This target structure presents a challenge for L2 learners of German due to its subregularity and low salience. With their eye movements being tracked, participants matched German auditory sentences (VSO order) with one of two pictures, displaying identical action scenes but varying in agent number. The number cue provided by the strong verbs allowed participants to predict whether the upcoming subject would be singular or plural. The analyses revealed significant prediction, measured as predictive eye movements toward the target picture and faster button-press responses. Prediction in the L2 group was weaker than in the L1 group and present in the eye movement data only. Higher working memory scores were linked to faster predictive presses. Approximately half of the participants had become aware of the predictive cue, and being aware facilitated prediction to a limited extent.

In this study, we propose an operationalization of the concept of emergence which plays a crucial role in usage-based theories of language. The abstractions linguists operate with are assumed to emerge through a process of generalization over the data language users are exposed to. Here, we use two types of computational learning algorithms that differ in how they formalize and execute generalization and, consequently, abstraction, to probe whether a type of language knowledge that resembles linguistic abstractions could emerge from exposure to raw data only. More specifically, we investigated whether a phone, undisputedly the simplest of all linguistic abstractions, could emerge from exposure to speech sounds using two computational learning processes: memory-based learning and error-correction learning (ECL). Both models were presented with a significant amount of pre-processed speech produced by one speaker. We assessed (1) the consistency or stability of what these simple models learn and (2) their ability to approximate abstract categories. Both types of models fare differently regarding these tests. We show that only ECL models can learn abstractions and that at least part of the phone inventory and its grouping into traditional types can be reliably identified from the input.

Research has suggested that children who speak African American English (AAE) have difficulty using features produced in Mainstream American English (MAE) but not AAE, to comprehend sentences in MAE. However, past studies mainly examined dialect features, such as verbal -s, that are produced as final consonants with shorter durations when produced in conversation which impacts their phonetic saliency. Therefore, it is unclear if previous results are due to the phonetic saliency of the feature or how AAE speakers process MAE dialect features more generally. This study evaluated if there were group differences in how AAE- and MAE-speaking children used the auxiliary verbs was and were, a dialect feature with increased phonetic saliency but produced differently between the dialects, to interpret sentences in MAE. Participants aged 6, 5–10, and 0 years, who spoke MAE or AAE, completed the DELV-ST, a vocabulary measure (PVT), and a sentence comprehension task. In the sentence comprehension task, participants heard sentences in MAE that had either unambiguous or ambiguous subjects. Sentences with ambiguous subjects were used to evaluate group differences in sentence comprehension. AAE-speaking children were less likely than MAE-speaking children to use the auxiliary verbs was and were to interpret sentences in MAE. Furthermore, dialect density was predictive of Black participant’s sensitivity to the auxiliary verb. This finding is consistent with how the auxiliary verb is produced between the two dialects: was is used to mark both singular and plural subjects in AAE, while MAE uses was for singular and were for plural subjects. This study demonstrated that even when the dialect feature is more phonetically salient, differences between how verb morphology is produced in AAE and MAE impact how AAE-speaking children comprehend MAE sentences.

We introduce the pair of special issues of Applied Psycolinguistics (this issue, next issue) titled “Towards a just and equitable applied psycholinguistics.” This paper motivates the need for this project, details the editorial process, and provides a brief summary of each article appearing in the special issues.

The purpose of this study was to examine the early growth of morphological awareness and its predictors. We followed 172 English-speaking Canadian children (82 girls, 90 boys, Mage = 75.56 months at the first assessment point) from Grade 1 to Grade 3 and assessed them on nonverbal IQ, phonological short-term memory, phonological awareness, letter knowledge, and vocabulary at the beginning of Grade 1 and on morphological awareness at the end of Grade 1, beginning and end of Grade 2, and beginning of Grade 3. Results of growth curve modeling showed different growth patterns for Word Analogy and Sentence Analogy. In addition, vocabulary and phonological awareness were associated with the initial status of morphological awareness, and phonological awareness and letter knowledge predicted the growth rate of morphological awareness. These findings suggest that code-related skills drive the development of morphological awareness during the early years of literacy instruction.

Heritage speakers—bilinguals who acquire minority languages naturalistically in infancy but are typically majority-language-dominant in adulthood—generally acquire grammars that differ systematically from the baseline input received in childhood. Yet not all areas diverge equally; understanding what characterizes divergence or resilience of a given feature is crucial to understanding heritage language acquisition. In this realm, we investigate the discourse-conditioned non-canonical word orders that mark information focus in Spanish. Focus bears the hallmarks of structures that diverge from the baseline, yet the evidence is mixed. We use an offline forced-choice task and an online self-paced reading task to compare heritage speakers’ judgments and processing to the baseline’s, and we find, echoing recent work, that the heritage speakers largely resemble baseline speakers. We interpret this convergence with reference to seven factors potentially affecting heritage language acquisition and identify one hypothesis—that focus facilitates processing due to its structural and pragmatic salience—as a promising explanation.

This study compared patterns of nonselective cross-language activation in L1 and L2 visual word recognition with different-script bilinguals. The aim was to determine (1) whether lexical processing is nonselective in the L1 (as in L2), and (2) if the same cross-linguistic factors affected processing similarly in each language. To examine the time course of activation, eye movements were tracked during lexical decision. Thirty-two Japanese–English bilinguals responded to 250 target words in Japanese and in English. The same participants and items (i.e., cognate translation equivalents) were used to directly compare L1 and L2 processing. Response latencies as well as eye movements representing early and late processing were analyzed using mixed-effects regression modeling. Similar cross-linguistic effects, namely cognate word frequency, phonological similarity, and semantic similarity, were found in both languages. These factors affected processing to different degrees in each language, however. While cognate frequency was significant as early as the first fixation, effects of cross-linguistic phonological and semantic similarity arose later in time. Increased phonological similarity slowed responses in L2 but speeded them in L1, while greater semantic overlap was facilitatory in both languages. Results are discussed from the perspective of the BIA+ model of visual word recognition.

In the time since the term “intersectionality” was first introduced by Kimberlé Crenshaw, the term has gained a measure of widespread, even viral popularity. Increasingly, psycholinguists are citing this concept to promote work which more fully engages with the consequences of human diversity for language processing. This piece discusses the ways in which “intersectionality” has thus far been engaged by the field of psycholinguistics. I argue that the common usage of the term “intersectionality” is notably out of step with the tradition of Black feminist scholarship from which it derives. Originally defined as an analytical framework for examining the effect of interlocking oppressions in erasing the distinctive experiences of multiply marginalized people, intersectionality should not be invoked without any serious and specific discussion of oppressive systems or erasure. To achieve a more just and equitable applied psycholinguistics and authentically promote intersectional approaches to understanding language behavior, intersectionality must be taken as a framework primarily engaging with effects of structural violence. The article concludes with some guidelines for readers to assist in distinguishing “intersectional” claims which perform erasure from those which reflect the original and intended anti-misogynoir applications of the theory.

Recent studies have demonstrated incontrovertibly that person perception influences language perception. Much of this research is predicated on the notion that social categories are stable constructs that are perceived similarly by members of various speech communities. Power differentials necessarily impact the legibility of the social performances circumscribed by macrosociological categories and thus bely any claim to objectivity in these categorization systems. Developing a more just applied psycholinguistics requires researchers to explicitly consider the role of power in language, how power shapes fields’ notions of what research questions are important and meaningful, and therefore how research data are collected, analyzed, and disseminated. We argue that psycholinguists should widely adopt approaches to studying linguistic processing in ways which acknowledge the role of social ideologies in shaping their outcome, and which reckon with how asymmetrical power relations shape the perception, acquisition, and judgment of both social and linguistic variation. We conclude with a series of guidelines intended to promote characterizations of social and linguistic diversity which accurately reflect the importance of power differentials and which engage ethically with sociopolitical goals of justice and equity.

ObjectiveThe COVID-19 pandemic dramatically altered social determinants of health including work, education, social connections, movement, and perceived control; and loneliness was commonly experienced. This longitudinal study examined how social determinants at the personal (micro), community (meso), and societal (macro) levels predicted loneliness during the pandemic.MethodsParticipants were 2056 Australian adults surveyed up to three times over 18 months in 2020 and 2021. Multi-level mixed-effect regressions were conducted predicting loneliness from social determinants at baseline and two follow-ups.ResultsLoneliness was associated with numerous micro determinants: male gender, lifetime diagnosis of a mental health disorder, experience of recent stressful event(s), low income, living alone or couples with children, living in housing with low natural light, noise, and major building defects. Lower resilience and perceived control over health and life were also associated with greater loneliness. At the meso level, reduced engagement with social groups, living in inner regional areas, and living in neighbourhoods with low levels of belongingness and collective resilience was associated with increased loneliness. At the macro level, increased loneliness was associated with State/Territory of residence.ConclusionsTherapeutic initiatives must go beyond psychological intervention, and must recognise the social determinants of loneliness at the meso and macro levels.

Our knowledge and theories about language acquisition are skewed towards urban languages, and primarily English (Kidd & Garcia, 2022). Cristia and colleagues convincingly show that studies on the acquisition of rural languages are scarce. The authors suggest that in rural settings, combining experimental and observational approaches is critical to testing and sharpening our theories about language acquisition. Nevertheless, they also acknowledge the numerous challenges that make it difficult to conduct, analyse and publish this type of work.

There have been some suggestions in linguistics and cognitive science that humans process continuous speech by routinely chunking it up into smaller units. The nature of the process is open to debate, which is complicated by the apparent existence of two entirely different chunking processes, both of which seem to be warranted by the limitations of working memory. To overcome them, humans seem to both combine items into larger units for future retrieval (usage-based chunking), and partition incoming streams into temporal groups (perceptual chunking). To determine linguistic properties and cognitive constraints of perceptual chunking, most previous research has employed short-constructed stimuli modeled on written language. In contrast, we presented linguistically naïve listeners with excerpts of natural speech from corpora and collected their intuitive perceptions of chunk boundaries. We then used mixed-effects logistic regression models to find out to what extent pauses, prosody, syntax, chunk duration, and surprisal predict chunk boundary perception. The results showed that all cues were important, suggesting cue degeneracy, but with substantial variation across listeners and speech excerpts. Chunk duration had a strong effect, supporting the cognitive constraint hypothesis. The direction of the surprisal effect supported the distinction between perceptual and usage-based chunking.

Talmy’s motion event typology has served as a fruitful framework for exploring bilingual cognition and language use. The present study extends this line of research to the bilingualism situation of an underrepresented Turkic language, i.e., Modern Uyghur, and Mandarin Chinese, and it does so by focusing on a relatively understudied type of motion, i.e., caused motion. The two languages are genetically and typologically distinct, and yet they share verb-framing as an important lexicalization pattern in encoding motion. This study, therefore, investigated whether and to what extent this structural overlap contributes to crosslinguistic influence in Uyghur–Chinese adult bilinguals’ construal of caused motion. Thirty Uyghur–Chinese adult bilinguals’ verbalizations were analyzed with respect to the number of semantic components expressed and the way they were syntactically packaged. Results were compared with relevant monolingual data, which showed that Uyghur–Chinese adult bilinguals displayed a strong L1 to L2 influence in syntactic packaging by overusing the verb-framed strategy in Mandarin Chinese. However, further comparisons with previous research on Uyghur–Chinese child and adult bilinguals’ motion construal revealed that, while structural overlap is a key factor motivating crosslinguistic influence, a coherent explanation of this phenomenon must consider more general principles of bilingual language processing and use.

In Australia and New Zealand, young construction workers have high suicide rates that are associated with increased psychological distress. Research so far has focused on risk factors, such as workplace bullying during young workers’ apprenticeship training. However, there is a gap in research on factors associated with fostering psychological well-being and the development of strength-based interventions for the industry. One factor which is related to psychological well-being is self-compassion, the ability to be empathic towards oneself during times of suffering or failure. The present study (N = 252) examined relationships between self-compassion, psychological well-being, psychological distress and exposure to workplace bullying in New Zealand construction apprentices. Results showed that self-compassion was positively and significantly related to psychological well-being and negatively related to psychological distress. Self-compassion also uniquely predicted all of the six dimensions of psychological well-being. Experiences of workplace bullying and psychological distress were substantial, and workplace bullying was positively related to psychological distress. Contrary to our hypothesis, self-compassion did not moderate the association between bullying and psychological distress. Overall, these findings indicate that self-compassion interventions may have promise as a mechanism to improve the well-being of construction apprentices.

Recent sociophonetic research has focused on the ways in which race and ethnicity influence language as well as how language is used to construct racial and ethnic identity. Comparisons of the speech of members of one ethnic group across different regions are still uncommon. In this study, fifty-one native American English speakers of Korean descent, hailing from three different dialect areas of the United States (Los Angeles County and Orange County, California; Harris County, Texas; and Gwinnett County, Georgia), were recorded speaking English in casual interviews. Their speech was analyzed for characteristics of local sound patterns in each region, including the Short Front Vowel Shift (California Vowel Shift) and the Southern Vowel Shift, as well as overall Vowel Space Area. All three groups showed evidence of the Short Front Vowel Shift, and none demonstrated the Southern Vowel Shift. The Californian speakers had the smallest vowel spaces, while the Georgian speakers had the largest. We relate these findings to the ways Korean Americans in Texas and California understand their ethnic identity vis-à-vis a kind of metropolitan or urban speech style in a highly multicultural environment, while, in comparison, Korean Americans in Georgia may use vowel space to highlight their orientation toward or away from local mainstream (white) cultural identity.

Previous studies have shown that caregivers’ sensitive, responsive interactions with young children can boost language development. We explored the association between caregivers’ sensitivity and the vocabulary development of their 8-to-36-month-olds during COVID-19 when family routines were unexpectedly disrupted. Measuring caregivers’ sensitivity from home interaction videos at three timepoints, we found that children who experienced more-sensitive concurrent interactions had higher receptive and expressive vocabularies (N=100). Children whose caregivers showed more-sensitive interactions at the beginning of the pandemic showed greater expressive vocabulary growth six (but not 12) months later (n=58). Significant associations with receptive vocabulary growth were not observed. Our findings highlight the importance of sensitivity at a time when other positive influences on language development were compromised.

This study conceptually replicated and extended Reid, Trofimovich, and O’Brien (2019), who found that native English speakers could be biased positively (or negatively) relative to a control condition in terms of how they rate non-native English speech. Our internet-based study failed to replicate Reid et al. across a wider population sample of “native” speakers (n = 189). Listeners did not change how they rated non-native English speech after social bias orientations and performed similarly across all five measures of speech and across age and race (Asian, Black, and Caucasian). We attribute our results to differences in the methods (in-person vs. online) and/or participants. Of note, roughly one-third of our “native” participants indicated proficiency in languages other than English and residency in 12 different English-speaking countries, despite identifying as a) fluent English speakers who b) used English primarily and c) acquired English before any other language from birth. These screening items taken together qualified “native” participants in line with traditional psycholinguistics research. We conclude that the concept of “nativeness” is tied to culture-specific perspectives surrounding language use. As such, the native/non-native categorical variable simultaneously serves and limits the advancement of psycholinguistics research.

There has recently been an increased interest in studying the language development of non-western languages. This is not new - it began in 1960’s and continued into the 1980’s and 1990’s. The current renewed interest is much welcomed, and will benefit from many of the experimental methods and theoretical insights developed over the past decades.

In the target article, Cristia, Foushee, Aravena-Bravo, Cychosz, Scaff, and Casillas (2023) convincingly show the need to broaden the current language acquisition research base, not only in linguistic diversity, but also in terms of regions and cultural groups studied. In conducting acquisition research in understudied populations, such as in rural settings, the authors highlight the importance of using a multi-method approach. They present the challenges in adapting these methods to new settings and offer possible ways to promote this type of research. In this commentary, we extend the discussion to understudied urban communities, as we encounter several of the concerns raised in Cristia et al. when collecting observational and experimental language acquisition data from Metro Manila, Philippines. We first describe the community we study, the challenges and modifications needed for conducting research in this setting, and end with a discussion of possible strategies to promote research in communities with understudied populations.

There is a large consensus (e.g., Cristia, Foushee, Aravena-Bravo, Cychosz, Scaff & Casillas, 2023; Kidd & Garcia, 2022) that diversification in language acquisition research is needed. Cristia et al. (2023) convincingly argue for studying language acquisition in rural populations and recommend combining observational and experimental approaches in doing so. In this commentary, we identify that diversification efforts must also include children growing up in non-western urban societies and that combining experiments with more easy-to-obtain data on language exposure can be a solid method to start with.

While socioeconomic disparities in the home language environment have been well established, the mechanisms explaining these disparities are poorly understood. One plausible mechanism is heightened stress. The current study investigated whether maternal perceived stress was 1) associated with measures of the home language environment, and 2) mediated the relation between socioeconomic disparities and the home language environment. Data from three independent studies were analyzed, which together comprised 322 mother-child dyads. Two studies included mothers and their six- to twelve-month-old infants (N = 227). The third included mothers and their five- to nine-year-old children (N = 95). Mothers reported their educational attainment, income, and stress. Language Environment Analysis (LENA) measured the home language environment. As has been previously reported, socioeconomic disparities were observed in adult words and conversational turns. Stress did not mediate these associations, nor was it associated with adult words or conversational turns. Alternate mechanisms for future exploration are discussed.

Multiple approaches – including observational and experimental – are necessary to articulate powerful theories of learning. Our field’s key questions, which rely on these varied methods, are still open. How do children perceive and produce language? What do they encounter in their linguistic input? What does the learner bring to the task of acquisition? Considerable progress has been made for the development of spoken English (especially by North American learners). Yet there is still a great deal to discover about how children in other populations proceed, especially populations in rural settings. To examine language learning in these populations, we need a multi-method approach. However, adapting and integrating methods, particularly experimental ones, to new settings can present immense challenges. In this paper, we discuss the opportunities and challenges facing researchers who aim to use a multimethodological approach in rural samples, and what the field of language acquisition can do to promote such work.

Abstract domains of knowledge may have social origins. However, whether abstract concepts (ACs) may also differentially affect communicative interaction and conversation has not been explored. Here, we studied ACs’ communicative functions by collecting in an Italian and an English sample, ratings for concrete concept (CC) and ACs related to three main dimensions: communicative/pragmatic [i.e., Openness to Negotiation (ON), Easiness to Start a Conversation (ESC)], semantic/metacognitive [i.e., Social Metacognition (SM) – perceived need of others, Word Confidence (WC), Contextual Availability (CA)], and emotional–experiential (i.e., Pleasantness, Valence, Familiarity). Overall, Italian participants judged it was easier to start a conversation, the more pleasant, familiar, and positively valenced were rated the concepts. Crucially, at lower values of the emotional–experiential component (i.e., Familiarity in the Italian sample, also Pleasantness and Valence in an English sample), there was an advantage of ACs over CCs in the ESC. Moreover, in the Italian sample, participants rated ACs higher on SM, ON, and lower on WC and CA. Notably, in both the Italian and English sample, ACs with higher ratings on the ESC dimension belonged to the Self-Sociality subcluster. The results offer new insights into the pragmatic aspects linked to ACs’ use.

This study explored the flexibility of the orthographic processing at parafoveal level by manipulating the relationship between flankers and targets in two lexical decision tasks. In the first, we presented the following flankers: (1) the same words as targets (farola farola farola); (2) targets with transposed non-adjacent letters (falora farola falora); (3) the targets with one different letter (fapola farola fapola); and (4) unrelated pseudowords as control stimuli (pilata farola pilata). The results show significant facilitatory effects for all three experimental conditions in comparison to the Unrelated one, as well as differences between the Transposed and One Different Letter when compared to the Identity condition. In the second experiment, the procedure was the same but with the following modifications: the transposed non-adjacent letters were vowels instead of consonants (forala farola forala), and we also presented a condition in which both vowels and consonants were transposed (folara farola folara). The results of the response latencies showed that all the experimental conditions generated facilitatory effects in comparison to the Unrelated condition, with no differences between them, although the analyses of the error rates additionally showed significant differences between the Identity and the Transposed and Vowel and Consonant Transposed conditions. These two experiments are interpreted in terms of a highly flexible orthographic processing of flankers at parafoveal level, both in relation to letter ordering and letter identification.

Much like early speech, early signing is characterised by modifications. Sign language phonology has been analysed on the feature level since the 1980s, yet acquisition studies predominately examine handshape, location, and movement. This study is the first to analyse the acquisition of phonology in the sign language of a Balinese village with a vibrant signing community and applies the same feature analysis to adult and child data. We analyse longitudinal data of four deaf children from the Kata Kolok Child Signing Corpus. The form comparison of child productions and adult targets yields three main findings: i) handshape modifications are most frequent, echoing cross-linguistic patterns; ii) modification rates of other features differ from previous studies, possibly due to differences in methodology or KK’s phonology; iii) co-occurrence of modifications within a sign suggest feature interdependencies. We argue that nuanced approaches to child signing are necessary to understand the complexity of early signing.

Few studies have investigated the feasibility of researching brief forms of dialectical behaviour therapy (DBT) for borderline personality disorder (BPD) in public mental health settings. This study aimed to provide preliminary evidence for the feasibility of implementing DBT over a 6-month period for BPD symptoms within Australian public mental health services. Of the 79 participants with BPD recruited, 62 commenced and 24 participants completed the therapy. The participants attended one of three outpatient DBT programmes and completed measures of BPD symptoms, DBT skills-use, and difficulties with emotion regulation at baseline and after 6 months of treatment. A major challenge with feasibility identified was the high attrition rate (61%). However, for completers there were significant improvements in BPD symptoms, DBT skills-use, and difficulties with emotion regulation. These effect sizes were used to estimate the sample sizes needed by future larger trials of brief DBT for BPD in public health settings. The implementation of brief DBT for BPD patients within a public mental health outpatient setting, appears to result in significant reductions in BPD symptoms. However, further exploration of strategies to reduce drop-out rates are required.

In ‘Being pragmatic about syntactic bootstrapping’, Hacquard (2022) argues that abstract syntax is useful for word learning, but that an additional cue, pragmatics, is both necessary and available for young children during the first steps of language acquisition. She focuses on modals and attitude verbs, where the physical context seems particularly impoverished as the sole basis for deriving meanings, and thus where linguistic cues may be particularly helpful. She convincingly shows how pragmatic and syntactic cues could be combined to help young language learners learn and infer the possible meanings of attitude verbs such as “think”, “know” or “want”. She also argues that, in some circumstances, syntax and pragmatics would need to be supplemented by semantic information from context – for instance, in the case of modals such as “might”, “can”, or “must”. We agree with Hacquard on the importance of the synergies between these different cues to meaning, and wish to add two other aspects of the input that might also be used by young children in these contexts. The aspects we describe can only be noticed when one analyzes concrete examples of what children hear in their everyday lives, something which Hacquard does very often in her work (e.g., Dieuleveut, van Dooren, Cournane & Hacquard, 2022; Huang, White, Liao, Hacquard & Lidz, 2022; Yang, 2022). Taking into account different cues for meaning would help the field go beyond current models of syntactic bootstrapping, and create an integrated picture of the synergies between different levels of linguistic information.

White monolingual Anglo-American values permeate language acquisition research, which extends into public health and educational policies. “Quality of language” in parent-child interactions is often called upon to explain weaknesses in the language development of children who are racialized, experiencing poverty, or bilingual. Indeed, many early intervention approaches build on this premise by aiming to improve the “quality of language” used by parents. We aimed to understand the conceptualizations of “quality of language” in studies of parent-child interaction through the critical lens of Community Cultural Wealth Theory and perspectives from development research across cultures. We completed a Systematic Concept Analysis of articles published from 2010 to 2022 and focused on parent-child interactions in the home environment. Our search identified 972 articles and 78 met the inclusion criteria, but only 45 papers provided a definition. These definitions covered eight conceptualizations but only three were previously described. We also found inequity in the use of this terminology, which focused on children who were bilingual, had disability, or experiencing poverty. Informed by a critical lens, we recommend the use of four new terms to encompass “quality of language.” We also recommend refraining from using this term as it is value-laden, poorly defined, and diminishes culturally sustaining language transmission practices.

The present study investigates current proposals that priming is a mechanism of cross-linguistic influence (CLI) in bilinguals by aiming to boost CLI through priming. In two cross-linguistic structural priming experiments with less-proficient adolescent (Study 1) and more highly proficient adult German-English learners (Study 2), we assess whether structural priming enhances CLI for well-formed, dispreferred, and ungrammatical structures. L2 learners in both studies showed CLI in their production, in particular for structures with word order overlap. They also exhibited short-term cross-linguistic priming of grammatical L1-L2 word orders in L2 English, which extended to longer-term priming among the more highly proficient learners in Study 2. However, there was no evidence that cross-linguistic priming increased the use of dispreferred or ungrammatical L1-based word orders in L2 English in either study. Rather, the overall production of these word orders decreased. Together, these results suggest that, while cross-linguistic priming leads learners to increase the use of shared, grammatical L1-L2 word orders, it leads to the inhibition of non-shared ungrammatical structures in L2 production. We conclude that priming has asymmetrical effects on CLI of grammatical and ungrammatical L1-based structures in the L2.

The present longitudinal study aimed to explore the connections between different linguistic profiles at kindergarten and reading achievements at first grade. These profiles are based on the two-dimensional model (Bishop & Snowling, 2004), which associates reading skills with phonological and other language abilities. This model was examined mainly in Indo-European languages but scarcely in Arabic. Arabic-speaking children were assigned to four linguistic profiles in kindergartens: low language (LL; N = 111), low phonology (LPh; N = 120), low language and low phonology (LLLPh; N = 139), and typical language and typical phonology (TLTPh; N = 135). Multivariate analysis was used to compare their reading achievements at first grade, and the overlap between linguistic and reading profiles was estimated. The results revealed significant differences between the different linguistic profiles in all reading measures. LLLPh group gained lower scores in reading tasks compared to the other groups. Significant relationships have been found between linguistic and reading profiles indicating reading difficulties among 14.5% of the children from TLTPh, 63% of LLLPh, 35% of LL, and 35.6% of LPh. The findings support the relationship between low linguistic skills and reading difficulties and emphasize the potential roles of both phonological and language skills for reading.

English monolinguals (Experiment 1) and first language (L1)-dominant, Spanish-English and Chinese-English bilinguals (Experiment 2), who differed in L1 orthographic depth (shallow: Spanish; deep: Chinese) and second language (L2–English) proficiency, decided whether visually presented letter strings were English words, while behavioral and EEG measures were recorded. The spelling-sound regularity and consistency of stimuli were covaried such that words had either regular/consistent (e.g., GATE) or irregular/inconsistent mappings (e.g., PINT). Irregular/inconsistent words elicited more positive P200 and less negative N400 amplitudes than regular/consistent words in monolinguals, yet only a P200 response in bilinguals. English proficiency modulated L2 reading strategies, such that bilinguals employed distinct reading unit sizes in the L2 than the L1 when L2 proficiency was low, but transferred L1 reading units to the L2 when L2 proficiency was high. ERP results suggest that high L2 proficiency may be a prerequisite to the cross-linguistic transfer of reading strategies.

The Mandarin Ba-construction is one of the most challenging constructions for L2 learners. The present study attributes the difficulty in developing the taxonomic representation of the Ba-construction to the interference of competing constructions. I conducted a syntactic priming experiment to investigate the representational relationship between the Ba-construction and its SVO counterpart in native Mandarin speakers and L2 Mandarin learners with or without the equivalent of the Ba-construction in their L1. It was found that native speakers and L2 learners whose L1 features a structure equivalent to the Ba-construction represented the two constructions distinctly, manifesting as a resistance to priming and a robust syntactic preference for the Ba-construction in the picture description task. Conversely, L2 learners whose L1 does not possess an equivalent of the Ba-construction were sensitive to syntactic priming, which indicates a lack of taxonomic representations of the Ba-construction in relation to its SVO counterpart. Such reduced differentiation between the two target constructions suggests a blocking effect that stems from L1 interference.

This study compared school-aged monolingual and bilingual English-as-a-foreign-language (EFL) learners in terms of understanding metaphors on recall, multiple-choice, and reasoning tasks. It also examined the relationship between cognitive capacity and understanding metaphors on different measures. A hundred and thirty Persian–Turkish early bilinguals and 122 monolingual Persian-speaking EFL learners took three different tests of metaphor comprehension and the Figural Intersections Test, a test of cognitive capacity. Bilinguals outperformed monolinguals in terms of cognitive capacity and understanding metaphors on two of the tasks, though with a small effect size. Furthermore, there was a significant positive relationship between cognitive capacity and the scores on the multiple-choice and reasoning tests, but not the recall test. Results suggest that bilingual L3 learners have an edge in understanding metaphors, reflecting a cognitive advantage.

Verb-marking errors are a characteristic feature of the speech of typically-developing (TD) children and are particularly prevalent in the speech of children with Developmental Language Disorder (DLD). However, both the pattern of verb-marking error in TD children and the pattern of verb-marking deficit in DLD vary across languages and interact with the semantic and syntactic properties of the language being learned. In this paper, we review work using a computational model called MOSAIC. We show how this work allows us to understand several features of the cross-linguistic data that are otherwise difficult to explain. We also show how discrepancies between the developmental data and the quantitative predictions generated by MOSAIC can be used to identify weaknesses in our current understanding and lead to further theory development; and how the resulting model (MOSAIC+) helps us understand differences in the cross-linguistic patterning of verb-marking errors in TD children and children with DLD.

Recent years have seen an increased interest in the study of heritage language bilinguals. However, much of the research on heritage bilingualism is fraught with deficit framing. In this article, we demonstrate how many of the assumptions that underlie this growing field of research and the way that heritage speakers are positioned as research subjects reveal ideologies that center and value monolingualism and whiteness. We problematize a number of ways in which these ideologies commonly show up in the frameworks and methodologies used in psycholinguistics to study this population. We advocate for frameworks such as usage-based linguistics and multicompetence that center the multidimensional experiences of bilinguals and embrace nuance and complexity. We call on the research community to examine their research designs and theories to dismantle the systems that maintain heritage bilingualism at the margins of bilingualism research.

Adopting a cross-language long-term repetition-priming paradigm, the current study systematically investigated number representation in Tibetan–Mandarin bilinguals. The study focused on three types of numerals: Arabic digits, Tibetan numerals, and Mandarin numerals. Experiment 1 examined lexical representation; participants performed a lexical decision task in the cross-language repetition-priming paradigm. Experiment 2 used a parity judgment task to examine conceptual representation. In both experiments, if the presentation of the numerals during the learning phase facilitated responses to their translation equivalents in the testing phase, it would indicate that they activate each other (i.e., a shared representation). Results showed that the presentation of Tibetan or Mandarin numerals did not facilitate subsequent responses to the Arabic digit equivalent. No cross-language repetition-priming effect between Tibetan and Mandarin numerals was found in the lexical decision task, indicating that Arabic digits, Tibetan number words, and Mandarin number words are stored separately at the lexical level. At the conceptual level, the results were quite the opposite, suggesting that these three types of numerals share a common representation. To sum up, the results imply that bilinguals’ number representation is similar to bilinguals’ language representation, providing a better understanding of number representation in bilinguals from a linguistic perspective.

Intolerance of uncertainty (IU) is a cognitive bias that leads to perception and intolerance of uncertainty and has associated negative cognitive, emotional, and behavioural responses. It plays a strong role in social anxiety disorder (SAD; Counsell et al., 2017). Our experimental study examined the impact of uncertainty related to a social stressor on SAD using a speech task. We examined features of SAD including anticipatory anxiety, anxiety during the task, willingness to perform the task, and avoidance of the task. Undergraduate students (N = 110, 88% female) with significant social anxiety completed a series of questionnaires, then were randomised to one of two conditions related to level of uncertainty about an impromptu speech task. The experimental condition (state IU) did not predict any of the outcome variables, while trait IU significantly predicted anxiety levels. Results indicate that increased uncertainty of a social situation does not impact acute anxiety levels in SAD and reinforce the strong role of trait IU as a transdiagnostic cognitive variable. Neither trait nor state IU predicted the willingness and avoidance variables. Results also highlighted the central role of the experience of anxiety on avoidance behaviours, above cognitive factors such as IU.

The methods of spatial statistics have been successfully applied to the study of linguistic variation, especially for detecting the existence of spatial patterns in the geographical distribution of linguistic features. However, the use of local indicators of spatial autocorrelation for detecting spatial clusters have been limited to continuous variables, and we propose to apply the new method of Anselin and Li (2019) for categorical variables to linguistic data. We illustrate this method with the case of Japanese rendaku, or sequential voicing, whose dialectal variation is still poorly documented. Focusing on regional differences in the frequency of rendaku, we examined the occurrence of rendaku for four lexemes in 4,921 place names from all Japan. A statistical analysis of local spatial association and an unsupervised density-based cluster analysis revealed the existence of two cluster areas of high rendaku frequency centered around Wakayama and Fukushima-Yamagata prefectures. This suggests that rendaku is more frequent in those dialects, and we recommend that further studies in the dialectal variation of rendaku start by looking at those areas.
