This study examined 4- and 5-year-olds' incremental interpretation of size adjectives, focusing on whether contrastive inferences are modulated by speaker behavior. Children (N = 120, 59 females, mostly White, tested between July, 2018 and August, 2019) encountered either a conventional or unconventional speaker who labeled objects in a correspondingly typical or atypical way. Critical utterances contained size adjectives (e.g., "Look at the big duck"). With conventional speakers, gaze measures indicated that children rapidly used the adjective to differentiate members of a contrasting pair, indicating that even 4-year-olds derive contrastive inferences. With unconventional speakers, contrastive inferences were delayed in processing. The findings demonstrate that preschoolers adjust their use of pragmatic cues when presented with evidence disconfirming their default assumptions about a speaker.

We examined the dimensionality of oral discourse skills (comprehension and retell of texts) and the relations of language and cognitive skills to the identified dimensions. Data were from 529 English-speaking second graders (M[subscript age] = 7.42; 46% female; 52.6% Whites, 33.8% African Americans, 4.9% Hispanics, 4.7% two or more races, 0.8% Asian Americans, 0.6% American Indians, 0.2% Native Hawaiians, 2.5% unknown; data from 2014-2015 to 2016-2017). Confirmatory factor analysis revealed that oral discourse skills are best described as four related but dissociable dimensions of narrative comprehension, narrative retell, expository comprehension, and expository retell (rs = 0.59-0.84). Language and cognitive skills had different patterns of relations to the identified dimensions and explained larger amounts of variance in comprehension than in retell.

Children are on a quest for knowledge. To achieve it, children must integrate separate but related episodes of learning. The theoretical model of memory integration posits that the process is supported by component cognitive abilities. In turn, memory integration predicts accumulation of a knowledge base. We tested this model in two studies (data collected in 2016-2018) with second (8-year-olds; n = 391; 196 female; 36% Black, 27% Hispanic/Latinx, 29% White, and 8% multiracial) and third (9-year-olds; n = 282; 148 female; 36% Black, 31% Hispanic/Latinx, 27% White, and 5% multiracial) graders. The results support the theoretical model and the role of verbal comprehension in learning new information, and also indicate that verbal comprehension alone is not sufficient to build knowledge.

In communicative situations, preschoolers use shared knowledge, or "common ground," to guide their interpretation of a speaker's referential intent. Using eye-tracking measures, this study investigated the time course of 4-year-olds' (n = 95) use of two different speakers' perspectives and assessed how individual differences in this ability related to individual differences in executive function and representational skills. Gaze measures indicated partner-specific common ground guided children's interpretation from the earliest moments of language processing. Nonegocentric online processing was positively correlated with performance on a Level 2 visual perspective-taking task. These results demonstrate that preschoolers readily use the perspectives of multiple partners to guide language comprehension and that more advanced representational skills are associated with the rapid integration of common ground information.

Researchers examined the effects of previewing on preschoolers' comprehension of narrative and educational content in a television program. Children (3-5 years, N = 107) watched an educational math episode in one of three conditions: no-preview control, education-focused expository preview, or story-focused narrative preview. A main effect of previewing was found, controlling for age, character familiarity, prior knowledge, and visual attention. Specifically, the narrative preview enhanced both narrative comprehension (including central, incidental, and inferential content) and educational comprehension (including direct learning and transfer), compared to a no-preview control. Conversely, the expository preview had no effect on comprehension. Findings are interpreted with respect to story schema and relevant cognitive theories of learning from media. Implications for educational media production are discussed.

Given limitations in the integrative scope of past research, basic questions about the organization and development of preschoolers' living kinds concept remain open to debate. This study was designed to address past limitations through use of a longitudinal design, extensive stimulus set, and alternate indices of understanding. Thirty-five English-speaking 3-year-olds from middle-class families in Albuquerque, New Mexico participated in four testing sessions over 1 year. Indices of understanding included statements that preschoolers generated about various living and nonliving objects, biological properties they attributed to the objects, and their characterization of objects as "alive" or not. Results reveal a multifaceted picture of developmental change in preschoolers' living kinds concept involving both the construction and elaboration of a core biological understanding.

Variability in children's language acquisition is likely due to a number of cognitive and social variables. The current study investigated whether individual differences in statistical learning (SL), which has been implicated in language acquisition, independently predicted 6- to 8-year-old's comprehension of syntax. Sixty-eight (N = 68) English-speaking children completed a test of comprehension of four syntactic structures, a test of SL utilizing nonlinguistic visual stimuli, and several additional control measures. The results revealed that SL independently predicted comprehension of two syntactic structures that show considerable variability in this age range: passives and object relative clauses. These data suggest that individual differences in children's capacity for SL are associated with the acquisition of the syntax of natural languages.

Two experiments with one hundred and fourteen 3- to 5-year-old children examined whether children understand that a printed word represents a specific spoken word and that it differs in this way from a drawing. When an experimenter read a word to children and then a puppet used a different but related label for it, such as "dog" for the word ‹puppy›, children often stated the puppet's label was incorrect. In an analogous task with drawings, children were more likely to state that the puppet was correct in using an alternative label. The results suggest that even young children who cannot yet read have some understanding that a written word stands for a specific linguistic unit in a way that a drawing does not.

Although the size of a child's vocabulary associates with language-processing skills, little is understood regarding how this relation emerges. This investigation asks whether and how the structure of vocabulary knowledge affects language processing in English-learning 24-month-old children (N = 32; 18 F, 14 M). Parental vocabulary report was used to calculate semantic density in several early-acquired semantic categories. Performance on two language-processing tasks (lexical recognition and sentence processing) was compared as a function of semantic density. In both tasks, real-time comprehension was facilitated for higher density items, whereas lower density items experienced more interference. The findings indicate that language-processing skills develop heterogeneously and are influenced by the semantic network surrounding a known word.

The present study investigated 3- to 7-year-olds' (N = 91) comprehension of two-clause sentences containing the temporal connectives before or after. The youngest children used an order of mention strategy to interpret the relation between clauses: They were more accurate when the presentation order matched the chronological order of events: "He ate his lunch, before he played in the garden" (chronological) versus "Before he played in the garden, he ate his lunch" (reverse). Between 4 and 6 years, performance was influenced by a combination of factors that influenced processing load: connective type and presentation order. An independent measure of working memory was predictive of performance. The study concludes that the memory demands of some sentence structures limits young children's comprehension of sentences containing temporal connectives.

Mothers' mental-state references predict individual differences in preschoolers' false-belief (FB) understanding; less is known about the origins of corresponding variation in school-age children. To address this gap, 105 children completed observations with their mothers at child ages 2 and 6, three FB tasks and a verbal comprehension test at age 3, and five FB tasks at age 6. Seventy-seven of these children completed five Strange Stories at age 10. Individual differences in mothers' cognitive references at child age 2 predicted variation in children's FB understanding at age 6 and Strange Stories scores at age 10 (controlling for number of mothers' turns and children's mental-state references, verbal comprehension and FB understanding at age 3, and mothers' cognitive references at child age 6).

Three studies investigated 3-year-old children's ability to determine a speaker's communicative intent when the speaker's overt utterance related to that intent only indirectly. Studies 1 and 2 examined children's comprehension of indirectly stated requests (e.g., "I find Xs good" can imply, in context, a request for X; N = 32). Study 3 investigated 3- and 4-year-old children's and adults' (N = 52) comprehension of the implications of a speaker responding to an offer by mentioning an action's fulfilled or unfulfilled precondition (e.g., responding to an offer of cereal by stating that we have no milk implies rejection of the cereal). In all studies, 3-year-old children were able to make the relevance inference necessary to integrate utterances meaningfully into the ongoing context.

Recent studies have shown that the metacognitive judgments adults infer from their experiences of encoding effort vary in accordance with their naive theories of intelligence. To determine whether this finding extends to elementary schoolchildren, a study was conducted in which 27 third graders (M[subscript age] = 8.27) and 24 fifth graders (M[subscript age] = 10.39) read texts presented in easy-or difficult-to-encode fonts. The more children in both grades viewed intelligence as fixed, the less likely they were to interpret effortful or difficult encoding as a sign of increasing mastery and the more likely they were to report lower levels of comprehension as their perceived effort increased. This suggests that children may use naive theories of intelligence to make motivationally relevant inferences earlier than previously thought.

Data from 492 Italian infants (8-18 months) were collected with the parental questionnaire MacArthur Bates Communicative Development Inventories to describe early actions and gestures (A-G) "vocabulary" and its relation with spoken vocabulary in both comprehension and production. A-G were more strongly correlated with word comprehension than word production. A clear developmental pattern for the different types of A-G was found. These findings are similar to those of different Western languages, indicating a common biological and cultural basis. The analysis of individual A-G and their relations with early words with a related meaning showed interesting similarities between the production of A-G with and without object manipulation and the comprehension and production of corresponding words. Results indicate that the transition from A-G to spoken language is mediated by word comprehension.

Eye movements were recorded while sixty-two 1-year-olds, 4-year-olds, and adults watched television. Of interest was the extent to which viewers looked at the same place at the same time as their peers because high similarity across viewers suggests systematic viewing driven by comprehension processes. Similarity of gaze location increased with age. This was particularly true immediately following a cut to a new scene, partly because older viewers (but not infants) tended to fixate the center of the screen following a cut. Conversely, infants appear to require several seconds to orient to a new scene. Results are interpreted in the context of developing attention skills. Findings have implications for the extent to which infants comprehend and learn from commercial video.

Educational TV has been consistently linked to children's learning. In this research, educational TV characteristics were identified, coded, and tested for their influence on children's program-specific comprehension and vocabulary outcomes. Study 1 details a content analysis of TV features including a program's macrostructure (i.e., narrative or expository) and learning strategies embedded in the macrostructure that support learning in print-based contexts. In Study 2, regression analyses were used to predict outcomes involving 71 second and third graders (average age = 7.63 years). Strategies were categorized as organizing, rehearsing, elaborating, or affective in function. Outcomes were uniformly higher for narrative macrostructures. Strategies used in narratives predicted relatively homogenous relations across outcomes, whereas strategies in expositories predicted quite heterogeneous relations across outcomes.

Two comprehension experiments were conducted to investigate whether young French-learning children (N = 76) are able to use a single number cue in subject-verb agreement contexts and match a visually dynamic scene with a corresponding verbal stimulus. Results from both preferential looking and pointing demonstrated significant comprehension in 30-month-olds with no preference for either singular or plural. These results challenge previous claims made on the basis of English and Spanish that comprehension of subject-verb agreement expressed as a bound morpheme is late, around 5 years of age (V. A. Johnson, J. G. de Villiers, & H. N. Seymour, 2005; A.-T. Perez-Leroux, 2005). Properties of the adult input were also analyzed. Possible implications for theories of syntactic acquisition are discussed.

The early noncry vocalizations of infants are salient social signals. Caregivers spontaneously respond to 30%-50% of these sounds, and their responsiveness to infants' prelinguistic noncry vocalizations facilitates the development of phonology and speech. Have infants learned that their vocalizations influence the behavior of social partners? If they have, infants should show an extinction burst in vocalizing when adults temporarily stop responding to infant vocalizations. Thirty-eight 5-month-olds were tested in the still-face paradigm with an unfamiliar adult. When the adult assumed a still face, infants showed an extinction burst. Thus, 5-month-olds have learned the social efficacy of their vocalizations on caregivers' behavior. Furthermore, the magnitude of 5-month infants' extinction bursts predicted their language comprehension at 13 months.

A test of advanced theory of mind (ToM), first introduced by F. Happe (1994), was adapted for children (mental, human, animal, and nature stories plus unlinked sentences). These materials were closely matched for difficulty and were presented to forty-five 7- to 12-year-olds with autism and 27 control children. Children with autism who showed ToM impairment on independent tests performed significantly more poorly than controls solely on the mental, human, and animal stories with greatest impairment on the former and least on the latter. Thus, a mentalizing deficit may affect understanding of biologic agents even when this does not explicitly require understanding others' mental states.

Changes in visual attention and story comprehension for children (N = 132) with attention deficit hyperactivity disorder (ADHD) and comparison peers were examined. Between the ages of 7 and 9 (Phase 1) and approximately 21 months later (Phase 2), children viewed 2 televised stories: 1 in the presence of toys and 1 in their absence. Both groups of children showed developmental increases in visual attention and stable group differences over time. Deficits in comprehension among children with ADHD, however, increased over time. Whereas comparison children's recall of factual and causal information increased over time in both viewing conditions, children with ADHD showed no developmental improvement in recall of factual information in the toys-present condition and no improvement in recall of causal relations in either viewing condition.

This study describes the development of social reasoning in school-age children. An irony task is used to assess 5-, 7-, and 9-year-olds' (N = 72) and adults' (N = 24) recursive understanding of others' minds. Guttman scale analysis demonstrates that in order to understand a speaker's communicative intention, a child needs to recognize the speaker's belief, the detection of which depends on the ability to identify the discrepancy between the intended and the expressed meaning. Only children who understand these aspects of mind are able to reflect on the speaker's attitude. Theory of mind and language ability make unique contributions to children's interpretation of irony over and above the impact of age and memory, but attunement to expressive prosody does not.

Two comprehension experiments were conducted to investigate whether German children are able to use the grammatical cues of word order and word endings (case markers) to identify agents and patients in a causative sentence and whether they weigh these two cues differently across development. Two-year-olds correctly understood only sentences with both cues supporting each other--the prototypical form. Five-year-olds were able to use word order by itself but not case markers. Only 7-year-olds behaved like adults by relying on case markers over word order when the two cues conflicted. These findings suggest that prototypical instances of linguistic constructions with redundant grammatical marking play a special role in early acquisition, and only later do children isolate and weigh individual grammatical cues appropriately.

This research was designed to examine the quality of children's aesthetic understanding of photographs, observe social interactions between parents and children in this aesthetic domain, and study whether qualitatively different dyadic interactions were associated with children's own aesthetic understanding. Parents and children (7-13 years; 40 dyads) individually completed measures of aesthetic understanding and jointly selected photographs for a souvenir scrapbook. Parents' artistic experience varied widely and was associated with their own performance on aesthetic understanding measures. Children's performance on the individual aesthetic tasks was related to age, but not to parents' art experience nor to the qualities of parent-child discussions of aesthetic concepts. Among both parents and children, artistic experience was associated with aesthetic preferences for photographs.

Two studies were conducted to investigate the specificity of the relationship between preschoolers' emerging executive functioning skills and false belief understanding. Study 1 (N=44) showed that 3- to 5-year-olds' performance on an executive functioning task that required selective suppression of actions predicted performance on false belief tasks, but not on false photograph tasks. Study 2 (N=54) replicated the finding from Study 1 and showed that performance on the executive functioning task also predicted 3- to 5-year-olds' performance on false sign tasks. These findings show that executive functioning is required to reason only about representations that are intended to reflect a true state of affairs. Results are discussed with respect to theories of preschoolers' theory-of-mind development.

About half of 2,581 low-income mothers reported reading daily to their children. At 14 months, the odds of reading daily increased by the child being firstborn or female. At 24 and 36 months, these odds increased by maternal verbal ability or education and by the child being firstborn or of Early Head Start status. White mothers read more than did Hispanic or African American mothers. For English-speaking children, concurrent reading was associated with vocabulary and comprehension at 14 months, and with vocabulary and cognitive development at 24 months. A pattern of daily reading over the 3 data points for English-speaking children and daily reading at any 1 data point for Spanish-speaking children predicted children's language and cognition at 36 months. Path analyses suggest reciprocal and snowballing relations between maternal bookreading and children's vocabulary.

This research investigated 4- through 7-year-olds' and adults' (n=64) concepts about the emotional consequences of desire fulfillment versus desire inhibition in situations where people's desires conflict with prohibitive rules. Results revealed developmental increases in attributing positive or mixed emotions to story characters that make willpower decisions and negative or mixed emotions to characters that transgress. These developmental changes in emotion predictions were accompanied by age-related differences in emotion explanations. Whereas 4- and 5-year-olds largely explained emotions in relation to the characters' goals, 7-year-olds and adults further explained how rules and future consequences influence emotions. Results are discussed in relation to connections among children's psychological, deontic, and future-oriented reasoning about emotions as well as the development of self-control.

How do infants come to understand references to absent objects? 14-month-old infants first learned a name for a novel toy, which was then placed out of view. The infants who listened to a story mentioning the nonvisible object, looked, pointed, and searched for it more often than did infants who heard a story using a different name. Their behavior was affected by minor changes in context; they responded to the name of the out-of-view toy less often when it was not easily accessible or after a delay. These findings indicate that the development of absence reference comprehension depends on the interaction of representational and contextual factors.

Complex complements are clausal objects containing tensed verbs (e.g., that she cried) or infinitives (e.g., to cry), following main verbs of communication or mental activities (e.g., say, want). This research examined whether English- and Cantonese-speaking 4-year-olds' complement understanding uniquely predicts their representation of other minds (i.e., theory of mind). Results showed that neither meaning of main verbs (communication vs. desire) nor complement structure (tensed vs. infinitival) affected the correlation between complement understanding and theory of mind. More important, the correlation became insignificant after controlling for general language comprehension. These findings led to the conclusion that the syntax of complement per se does not contribute uniquely to theory-of-mind development; general language comprehension is a more important factor to consider.

This study investigated 2-year-olds' understanding of others' intentions in a social learning context. After seeing a demonstration of how to open a box, children in two "No Prior Intention" conditions were less likely than those in "Prior Intention" conditions to open the box themselves when the adult unsuccessfully tried to open it. Results suggest that understanding prior intentions enables young children to learn a complex task. (JPB)

Children's conceptions of the emotions of guilt versus shame were investigated in 2 studies involving children ages 7 to 9 and 10 to 12. Age-related differences in conceptions of guilt and shame emerged. The older children understood the adaptive implications of both emotions, whereas the younger children perceived them more in terms of the possible reactions of others. (GLR)

Analysis of natural language data from children up to six years of age revealed that by the third year, children clearly distinguished between reality and a variety of nonreal contrasts in their everyday speech. An experimental study in which children were questioned about the reality and appearance of a variety of items confirmed findings of the natural language study. (RH)

Reveals that during the elementary school years, children acquire a firm understanding of the brain as the primary locus of psychological attributes and identity. The early school years, when children are five to seven years old, appear to be a transitional phase, when performance is variable and subject to task conditions. (RH)

Subjects were 30 participants at each of 4 ages: 5, 7, and 10 years, and adult. Subjects described objects ordered in pairs. Children of 5 and 7 years improved their ability to understand visual metaphors which display a topic-visual interaction. From age 5 to adulthood, subjects improved their ability to comprehend metaphoric similarity. (RH)

Two experiments investigated the possibility that three year olds would do better on tasks in which belief cues were stronger than on standard false belief tasks, in which the children could reason backward to the belief from its effects. Findings provided strong support for the view that three year olds do not fully understand the representational nature of belief. (RH)

Results of three experiments suggest that, in contrast to the claims made by Wimmer and others (1988), three- and four-year-old children understand that looking leads to knowing. The three- and four-year-olds' difficulty in the study lay mainly in the form of the questions that they were asked. (RH)

Four studies determined when first, second, and third graders recognize that they make inferences to understand text, and the effect of this recognition on their ability to revise text and monitor its informativeness. Younger children tended to attribute inferred information to the text, while older children clearly distinguished inferred and explicit text information. (RH)

Results of four studies confirmed the hypothesis that three year olds would have less difficulty inferring that another person holds an odd belief about a matter of taste or value than they have in inferring that another person holds a false belief about a matter of verifiable fact. (RH)

Assessed first and third graders' and undergraduates' knowledge of strategies appropriate to comprehension and memory. Also assessed their knowledge of task variables affecting comprehension and memorization tasks. Only undergraduates showed understanding of comprehension-memory distinction. Third graders showed some understanding of differential effectiveness of strategies. (BC)

Examined preschoolers' and second and fifth graders' development of two types of perspective taking: (1) perspective taking based on differences in the information available to two people; and (2) perspective taking based on differences in weighting the same information. (RH)

Ability to identify the sexes, understanding of gender group membership, temporal stability of gender, and gender consistency over situational changes were assessed in a sample of 61 boys and girls of 3-5 years of age. Findings suggested that only a rudimentary understanding of gender is acquired by children before the sex-typing process begins. (RH)

Children's use of the terms "lie" and "truth" was examined. Participants were 150 subjects in five groups: nursery schoolers, preschoolers, first graders, fifth graders, and adults. Results support the development of definitional prototypes for the concepts of lie and truth. (RH)

Results indicate that children who witness teachers' appraisal actions interpret some of them differently at different ages. Participants were 136 first through sixth graders who were assessed on measures of perceptions of target children and perceptions of teacher's opinions of target children. (RH)

In two experiments 96 children and eight adults were tested for comprehension of the modifier-head relation in compounds such as apple-knife or were asked to label objects with compounds. Results show that by age three children reliably interpret novel compounds and made use of novel compounds to subcategorize. (RH)
