The current study investigates whether self-talk phrases can influence behavior in Ultimatum Games. In our three self-talk treatments, participants were instructed to tell themselves (i) to keep their own interests in mind, (ii) to also think of the other person, or (iii) to take some time to contemplate their decision. We investigate how such so-called experimenter-determined strategic self-talk phrases affect behavior and emotions in comparison to a control treatment without instructed self-talk. The results demonstrate that other-focused self-talk can nudge proposers towards fair behavior, as offers were higher in this group than in the other conditions. For responders, self-talk tended to increase acceptance rates of unfair offers as compared to the condition without self-talk. This effect is significant for both other-focused and contemplation-inducing self-talk but not for self-focused self-talk. In the self-focused condition, responders were most dissatisfied with unfair offers. These findings suggest that use of self-talk can increase acceptance rates in responders, and that focusing on personal interests can undermine this effect as it negatively impacts the responders’ emotional experience. In sum, our study shows that strategic self-talk interventions can be used to affect behavior in bargaining situations.

There is no agreement regarding the relationship between narrative abilities in the two languages of a bilingual child. In this paper, we test the hypothesis that such cross-language relationships depend on age and language exposure by studying the narrative skills of 32 Indonesian-Dutch bilinguals (mean age: 8;5, range: 5;0–11;9). The narratives were elicited by means of the Multilingual Assessment Instrument for Narratives (MAIN) and analysed for story structure, episodic complexity and use of internal state terms (ISTs) in the home language (Indonesian) and majority language (Dutch). The results demonstrate that story structure scores in the home language (but not in the majority language) were positively related to age. Exposure measures (current Dutch/Indonesian input, current richness of Dutch/Indonesian input, and length of exposure to Dutch) did not predict the macrostructure scores. There was a significant positive cross-language relationship in story structure and episodic complexity, and this relationship became stronger as a function of length of exposure to Dutch. There was also a positive cross-lingual relation in IST use, but it became weaker with age. The results support the idea that narrative skills are transferable between languages and suggest that cross-language relationships may interact with age and exposure factors in differential ways.

One of the most influential ideas within the domain of cognition is that of embodied cognition, in which the experienced world is the result of an interplay between an organism’s physiology, sensorimotor system, and its environment. An aspect of this idea is that linguistic information activates sensory representations automatically. For example, hearing the word ‘red’ would automatically activate sensory representations of this color. But does linguistic information prioritize access to awareness of congruent visual information? Here, we show that linguistic verbal cues accelerate matching visual targets into awareness by using a breaking continuous flash suppression paradigm. In a speeded reaction time task, observers heard spoken color labels (e.g., red) followed by colored targets that were either congruent (red), incongruent (green), or neutral (a neutral noncolor word) with respect to the labels. Importantly, and in contrast to previous studies investigating a similar question, the incidence of congruent trials was not higher than that of incongruent trials. Our results show that RTs were selectively shortened for congruent verbal–visual pairings, and that this shortening occurred over a wide range of cue–target intervals. We suggest that linguistic verbal information preactivates sensory representations, so that hearing the word ‘red’ preactivates (visual) sensory information internally.

Interpreting subjectivity in causal relations takes effort: Subjective, claim-argument relations are read slower than objective, cause-consequence relations. In an eye-tracking-while-reading experiment, we investigated whether connectives and stance markers can play a facilitative role. Sixty-five Chinese participants read sentences expressing a subjective causal relation, systematically varied in the use of stance markers (no, attitudinal, epistemic) in the first clause and connectives (neutral suoyi “so”, subjective kejian “so”) in the second clause. Results showed that processing subjectivity proceeds highly incrementally: The interplay of the subjectivity markers is visible as the sentence unfolds. Subjective connectives increased reading times, irrespective of the type of stance marker being used. Stance markers did, however, facilitate the processing of modal verbs in subjective relations. We conclude that processing subjectivity involves evaluating how the argument supports the claim and that connectives, modal verbs, and stance markers function as processing instructions that help readers achieve this evaluation.

Contains fulltext : 282382.pdf (Publisher’s version ) (Open Access) Persuasive messages aim to influence people's behavior. Arguments in these messages typically refer to the positive consequences of the advocated behavior or the negative consequences of failing to do so. It has been claimed that people automatically generate a judgment about the message's convincingness. We present the Perceived Convincingness Model (PCM) to explain how people generate this judgment based upon the fluency with which they process the message and the intensity of the resulting emotions. When these experiences are elicited by the processing of the message's arguments, they can be crude, yet relevant indicators of the extent to which the arguments meet the normative criteria of acceptability, relevance, and sufficiency. Thus, under some conditions, trusting one’s feelings may be a rational strategy when deciding to heed an advice or not. 9 p.

In decision-making people react differently to positive wordings than to negatives, which may be caused by negativity bias: a difference in emotional force of these wordings. Because emotions are assumed to be activated more strongly in one’s mother tongue, we predict a Foreign Language Effect, being that such framing effects are larger in a native language than in a foreign one. In two experimental studies (N = 475 and N = 503) we tested this prediction for balanced and unbalanced second language users of Spanish and English and for three types of valence framing effects. In Study 1 we observed risky-choice framing effects and attribute framing effects, but these were always equally large for native and foreign-language speakers. In our second study, we added a footbridge dilemma to the framing materials. Only for this task we did observe a Foreign Language Effect, indicating more utilitarian choices when the dilemma is presented in L2. Hence, across two studies, we find no Foreign Language Effect for three types of valence framing but we do find evidence for such an effect in a moral decision task. We discuss several alternative explanations for these results.

The present project provided causal evidence for self-regulation of social-media content and identified a potential underlying neural mechanism. We tested the premise that successful self-regulation requires limiting the mental representation of temptations in working memory. We showed that loading working memory with neutral contents via attentional distraction, relative to passively watching tempting social-media stimuli, resulted in reduced self-reported desire to use social media, reduced initial attention allocation toward social-media stimuli (reduced late-positive-potential amplitudes), and reduced online representation of social- media stimuli in working memory (reduced contralateral-delay-activity amplitudes).

Verbal insults go against a universal moral imperative not to inflict harm on others, and they also pose a threat to one's face or reputation. As such, these “verbal slaps in the face” provide a unique opportunity to explore the interface between language and emotion. We used electroencephalography (EEG) and skin conductance (SC) recordings to compare the short-term impact of verbal insults such as “Linda is an idiot” or “Paula is horrible” to that of more positive evaluations (e.g., “Linda is an angel”, “Paula is impressive”) and neutral factual descriptions (e.g., “Linda is a student”), examining how responses to these various speech acts adapt as a function of massive repetition. By using either the participant's or somebody else's name, we also explored how statement impact depended on who was being evaluated. Multilevel ERP analysis with three predesignated latency ranges revealed an early insult effect in P2 amplitude that was highly robust over repetition and also did not depend on who the insult was about. This P2 effect points to a very rapid and stable capture of emotional attention, plausibly triggered by the retrieval of evaluative word meaning from long-term memory. Insults also elicited a larger late positive potential (LPP), again regardless of who the insult was about, but this later effect did not withstand repetition. Skin conductance responses showed that insults did not lead to more arousal than compliments did. In all, our findings suggest that in a standard psycholinguistic comprehension experiment without real interaction between speakers, insults deliver lexical “mini-slaps in the face,” such that the strongly negative evaluative words involved (e.g., “idiot”) automatically grab attention during lexical retrieval, regardless of how often that retrieval occurs.

Many of our everyday emotional responses are triggered by language, and a full understanding of how people use language therefore also requires an analysis of how words elicit emotion as they are heard or read. We report a facial electromyography experiment in which we recorded corrugator supercilii, or “frowning muscle”, activity to assess how readers processed emotion-describing language in moral and minimal in/outgroup contexts. Participants read sentence-initial phrases like “Mark is angry” or “Mark is happy” after descriptions that defined the character at hand as a good person, a bad person, a member of a minimal ingroup, or a member of a minimal outgroup (realizing the latter two by classifying participants as personality “type P” and having them read about characters of “type P” or “type O”). As in our earlier work, moral group status of the character clearly modulated how readers responded to descriptions of character emotions, with more frowning to “Mark is angry” than to “Mark is happy” when the character had previously been described as morally good, butnotwhen the character had been described as morally bad. Minimal group status, however, did not matter to how the critical phrases were processed, with more frowning to “Mark is angry” than to “Mark is happy” across the board. Our morality-based findings are compatible with a model in which readers use their emotion systems to simultaneously simulate a character’s emotion and evaluate that emotion against their own social standards. The minimal-group result does not contradict this model, but also does not provide new evidence for it.

Adults often use prenominal adjectives for predicting the upcoming referent, either based on one’s knowledge of prototypical exemplars (e.g., elephants are always big) or based on the contrasting properties of objects (e.g., big box vs. small box). This paper seeks to determine whether Dutch-speaking three-year-olds can also process adjective-noun phrases incrementally and use the information provided in the adjective to identify the target referent even before the noun is pronounced. In order to test this, we conducted an eye-tracking experiment using the Visual World Paradigm. The results replicate previous research by showing that three-year-olds are able to identify the target referent through their knowledge of prototypical exemplars as fast as adults, even before the noun is pronounced. However, our results reveal that the ability to use contrastive information for referent identification is far more limited at that age, indicating that contrastive (relative) processing of prenominal adjectives is more demanding than prototype-based (absolute) interpretations.

Adopting open science principles can be challenging and time-intensive, because doing so requires substantial conceptual education and training in the use of new tools. This paper introduces the Workflow for Open Reproducible Code in Science (WORCS): A step-by-step procedure that researchers can follow to make a research project open and reproducible. The purpose of the workflow is to lower the threshold for adoption of open science principles. It is based on established best practices, and can be used either in parallel to, or in absence of, top-down requirements by journals, institutions, and funding bodies. To facilitate widespread adoption, the WORCS principles have been implemented in the R package worcs, which offers an RStudio project template and utility functions for specific workflow steps. This paper introduces the conceptual workflow, discusses how it meets different standards for open science, and addresses the functionality provided by the R implementation, worcs. This paper is primarily targeted towards scholars conducting research projects in R, conducting research that involves academic prose, analysis code, and (optionally) tabular data. However, the workflow is flexible enough to accommodate other scenarios, and offers a sensible starting point for customized solutions. The source code for the R package and manuscript, and a list of user examples of WORCS projects, are available at https://github.com/cjvanlissa/worcs.

Multilingual children are faced with the task of selectively using the linguistic systems of their languages. Previous research has shown that although bilinguals may make more errors in production and comprehension than their monolingual peers, less cognitively demanding processing experiments may reveal target-like performance. This has been attributed to several factors, among which language transfer and processing limitations. In this study we investigate the processing of additive connectives in both languages of German–Russian bilingual children using the Visual World Paradigm. Previous research has shown that bilingual children make many errors in the production of these connectives in Russian. The results show that the processing behaviour in both languages of the bilingual children does not differ from that of their monolingual peers. This finding is compatible with the view that errors in production and in more demanding comprehension tasks are due to processing limitations.

This paper studies the acquisition of Russian pronominal gender by Dutch-Russian simultaneous bilinguals (4;3-7;11) growing up in the Netherlands. The performance of the bilingual group is compared to that of age-matched monolinguals with and without developmental language disorder (DLD). We hypothesize that reduced exposure toRussian in the minority-language context may lead to delays in language development, comparable to problems attested in DLD (in this case due to reduced intake). The results of a narrative elicitation task demonstrate that both monolingual groups performed at ceiling from age 4 onwards. Monolingual children with DLD were as accurate at using pronominal gender as their unimpaired peers fromthe earliest ages studied, which supports the processing accounts of DLD taking morphological richness of the target language into account. In contrast, 4-year-old bilinguals performed around chance level. The performance of the bilingual group improved with age and reached the monolingual level only by age 7. The results suggest that reduced input has more impact on theacquisition of gender in a morphologically rich language, whereas the possible effects of DLD are no longer visible after age 3.

a b s t r a c t Many mammalian species, as well as birds, are able to use a mirror either in the context of self-recognition, or instrumentally for discovering and manipulating objects that cannot be perceived directly. A noteworthy study by Broom et al. (2009) investigated the ability of pigs (Sus scrofa) to use a mirror to locate a hidden food source. The mirror-experienced pigs appeared to be able to bypass a solid barrier that blocked direct view of a food bowl when the food bowl could be seen via a mirror. We tried to replicate these findings using 2 groups of 11 piglets each. The procedure used for testing the first group of 11 pigs followed Broom's description as closely as possible. Only two of the pigs of the first group were able to locate the hidden food bowl during the mirror test. Therefore, measures were taken to increase the number of pigs noticing the mirror in the second group of 11 pigs. Now, although pigs notice the mirror significantly earlier, only 1 of the mirror-experienced pigs and none of the mirror-naive pigs used the detour around the partition wall to reach the hidden food. We take this observation as evidence that the pigs did not understand what the mirror image represents, and did not use the mirror to locate food. This indicates that not all pigs are capable of using mirrors under all circumstances, and thus that mirror use may be at the upper limits of cognitive capacity of these animals at this age. © 2014 The Authors.

To understand language people form mental representations of described situations. Linguistic cues are known to influence these representations. In the present study, participants were asked to verify whether the object presented in a picture was mentioned in the preceding words. Crucially, the picture either showed an intact original state or a modified state of an object. Our results showed that the end state of the target object influenced verification responses. When no linguistic context was provided, participants responded faster to the original state of the object compared to the changed state (Experiment 1). However, when linguistic context was provided, participants responded faster to the modified state when it matched, rather than mismatched, the expected outcome of the described event (Experiment 2 and Experiment 3). Interestingly, as for the original state, the match/mismatch effects were only revealed after reading the past tense (Experiment 2) sentences but not the future-tense sentences (Experiment 3). Our findings highlight the need to take account of the dynamics of event representation in language comprehension that captures the interplay between general semantic knowledge about objects and the episodic knowledge introduced by the sentential context.

Simple Summary Chickens raised to lay eggs are housed from hatch in groups of animals of the same age, and without maternal care from a broody hen. There are several hybrid lines of hens used in egg farming, each of which show their own behavioral profile. Both the presence (or absence) of a mother hen and genetics may affect cognition, social interactions and fear. In this study, we showed that in our tests, genetics have a strong effect on fear and sociality. Maternal care had very little effect on any of the tests used. The strong effect of genetic background highlights that changes made to increase welfare need to consider the genetics of the chicken in question. The lack of effect of maternal care may indicate that breeds of chickens used in current farming practices were inadvertently selected to respond very little to maternal care. Abstract Both genetic background and maternal care can have a strong influence on cognitive and emotional development. To investigate these effects and their possible interaction, White Leghorn (LH) and Brown Nick (BN) chicks, two hybrid lines of layer hen commonly used commercially, were housed either with or without a mother hen in their first five weeks of life. From three weeks of age, the chicks were tested in a series of experiments to deduce the effects of breed and maternal care on their fear response, foraging and social motivation, and cognitive abilities. The LH were found to explore more and showed more attempts to reinstate social contact than BN. The BN were less active in all tests and less motivated than LH by social contact or by foraging opportunity. No hybrid differences were found in cognitive performance in the holeboard task. In general, the presence of a mother hen had unexpectedly little effect on behavior in both LH and BN chicks. It is hypothesized that hens from commercially used genetic backgrounds may have been inadvertently selected to be less responsive to maternal care than ancestral or non-commercial breeds. The consistent and strong behavioral differences between genetic strains highlights the importance of breed-specific welfare management processes.

Simple Summary Osteoarthritis is a cause of lameness in pigs. It causes pain for affected pigs and reduces profit for the farmer. From an acute problem, it progresses into a chronic condition. To study treatments for osteoarthritis, a model that mimics the functional and structural aspects of osteoarthritis is needed. To induce osteoarthritis, we injected a chemical compound (Monosodium Iodoacetate) into the carpal joint of 10 pigs (treatment group). Ten other pigs were injected with an innocuous substance (control group). We assessed their gait by visual inspection and with a device that measures weight-bearing on each limb. After 68 days, we euthanized the pigs and examined the tissues of injected joints microscopically. We could confirm structural joint changes resembling osteoarthritis in 8 of 10 pigs in the treatment group These pigs also placed less weight on their affected limb compared to the control group on day 3, 14, 28, and 56. Visually, these pigs were only more lame on day 1. Treatment with Monosodium Iodoacetate caused joint changes and lameness resembling those of naturally-occurring osteoarthritis. Although the model needs improvement for use in visual lameness, it enables the study of (drug) intervention on objective movement–pain behavior and structural joint changes. Abstract Lameness is a common problem in pigs, causing welfare issues in affected pigs and economic losses for farmers. It is often caused by osteoarthrosis (OA) in its acute or chronic form. We assessed face and construct validity of a potential model for naturally-occurring OA and its progression to chronic OA. Such a model would allow the assessment of possible interventions. Monosodium-iodoacetate (MIA) or isotonic saline was deposited in the intercarpal joint of 20 growing pigs. Functional effects were assessed using subjective (visual lameness scoring) and objective (kinetic gait analysis) techniques at several timepoints. Structural effects were assessed by histopathology at 68 days. Eight out of 10 MIA treated animals had histopathological OA lesions confirmed in the target joint, while for all saline treated animals the target joint was judged to be normal. Pressure mat analysis revealed increased asymmetric weight bearing in these animals compared to the control group on day 3, 14, 28 and 56. Visual scoring only showed a difference between groups on day 1. MIA did not cause prolonged visible lameness, thus face validity for OA under field conditions was not entirely met. Since objective gait parameters showed decreased weightbearing as a behavioral expression of pain, it may be used as a general model for movement-induced pain in pigs.

Cultural Heritage (CH) resources are partial, heterogeneous, discontinuous, and subject to ongoing updates and revisions. The use of semantic web technologies associated with 3D graphical tools is proposed to improve access, exploration, exploitation and enrichment of these CH data in a standardized and more structured form. This article presents the monitoring work developed for more than ten years on the excavation of the Xlendi site. Around an exceptional shipwreck, the oldest from the Archaic period in the Western Mediterranean, we have set up a unique excavation at a depth of 110m assisted by a rigorous and continuous photogrammetry campaign. All the collected results are modelled by an ontology and visualized with virtual and augmented reality tools that allow a bidirectional link between the proposed graphical representations and the non-graphical archaeological data. It is also important to highlight the development of an innovative 3D mobile app that lets users study and understand the site as well as experience sensations close to those of a diver visiting the site., peer-reviewed

Simple Summary ‘Crowding’, keeping too many birds per m2, is one of the largest welfare concerns in the poultry industry. It is therefore worrisome that there is a gap in research investigating the effects of high stocking densities during the rearing phase of laying hens. This study evaluated anxious behavior and corticosterone levels, a hormone involved in the stress response, during the first 10 weeks of laying hen chicks housed under three different crowding conditions: undercrowding, conventional crowding, and overcrowding. We found that overcrowded chicks displayed more anxious behavior compared to undercrowded chicks. Corticosterone levels were elevated in both extreme groups in week 3, but dropped to values of the conventional crowding group at week 10. We conclude that current conventional stocking densities do not seem to impair the welfare state of the laying hen chick, and that a three-fold in- or decrease of density influences stress and anxiety, but within the adaptive capacity of the chick. Important side-notes to this conclusion are that an increase of stocking density did result in a slower rate of adaptation, and that we currently do not know if there are long-term consequences of different crowding densities reaching into the laying period. Abstract The recent increases in stocking density, in extreme cases resulting in ‘crowding’, have a major impact on poultry welfare. In contrast to available research on adult laying hens, there is a gap in the literature studying the rearing phase. The present study investigated the effects of stocking density during the rearing period on the welfare of the laying hen chick. The chicks were housed under one of three crowding conditions, increasing with age: undercrowding (500-1000-1429 cm2 per chick), conventional crowding (167-333-500 cm2 per chick), or overcrowding (56-111-167 cm2 per chick). The parameters evaluated encompassed behavioral and physiological factors related to anxiety and stress. We found that during the first 6 weeks, overcrowded chicks displayed more anxious behavior than undercrowded chicks, and both extreme densities induced higher corticosterone levels compared to chicks housed under conventional crowding. At 10 weeks of age, plasma corticosterone had dropped to the level of conventional crowding group in both groups, whereas feather corticosterone remained high only in the overcrowded group. We conclude that current conventional stocking densities do not seem to impair the welfare state of the laying hen chick, and that a three-fold increase or decrease of density influences corticosterone levels and anxious behavior, but within the adaptive capacity of the chick. Important side notes to this conclusion are that an increase of stocking density did result in a slower rate of adaptation, and that there could be long-term consequences of both the different stocking densities and/or increased costs of adaptation.

Time is central to human cognition, both in terms of how we understand the world and the events that unfold around us as well as how we communicate about those events. As such, language has morphological systems, such as temporal adverbs, tense, and aspect to convey the passage of time. The current study explored the role of one such temporal marker, grammatical aspect, and its impact on how we understand the temporal boundaries between events conveyed in narratives. In Experiments 1 and 2, participants read stories that contained a target event that was either conveyed with a perfective (e.g., watched a movie) or imperfective aspect (e.g., was watching a movie) and engaged in an event segmentation task. Events described in the perfective aspect were more often perceived as event boundaries than events in the imperfective aspect, however, event duration (long vs. short) did not impact this relationship in Experiment 2. Experiment 3 demonstrated that readers were sensitive to grammatical aspect and event duration in the context of a story continuation task. Overall this study demonstrates that grammatical aspect interacts with world knowledge to convey event structure information that influences how people interpret the end and beginning of events.

Spatial cognition in vertebrates is adversely affected by a lack of environmental complexity during early life. However, to our knowledge, no previous studies have tested the effect of early exposure to varying degrees of environmental complexity on specific components of spatial cognition in chickens. There are two main rearing systems for laying hens in the EU: aviaries and cages. These two systems differ from one another in environmental complexity. The aim of the present study was to test the hypothesis that rearing in a barren cage environment relative to a complex aviary environment causes long-lasting deficits in the ability to perform spatial tasks. For this purpose, 24 white Dekalb laying hens, half of which had been reared in an aviary system and the other half in a conventional cage system, were tested in a holeboard task. Birds from both treatment groups learnt the task; however, the cage-reared hens required more time to locate rewards and had poorer levels of working memory. The latter finding supports the hypothesis that rearing in a barren environment causes long-term impairment of short-term memory in chickens.

Low birth weight (LBW) in humans is a risk factor for later cognitive, behavioural and emotional problems. In pigs, LBW is associated with higher mortality, but little is known about consequences for surviving piglets. Alteration in hypothalamic-pituitary-adrenal axis function in LBW pigs suggests altered emotionality, but no behavioural indicators have been studied. Decision-making under uncertain conditions, e.g., risk or ambiguity, is susceptible to emotional influences and may provide a means of assessing long-term effects of LBW in piglets. We tested LBW (N = 8) and normal-birth-weight (NBW; N = 8) male pigs in two decision-making tasks. For decision-making under risk, we developed a simple two-choice probabilistic task, the Pig Gambling Task (PGT), where an 'advantageous' option offered small but frequent rewards and a 'disadvantageous' option offered large but infrequent rewards. The advantageous option offered greater overall gain. For decision-making under ambiguity, we used a Judgement Bias Task (JBT) where pigs were trained to make an active response to 'positive' and 'negative' tone cues (signalling large and small rewards, respectively). Responses to ambiguous tone cues were rated as more or less optimistic. LBW pigs chose the advantageous option more often in later blocks of the PGT, and were scored as less optimistic in the JBT, than NBW pigs. Our findings demonstrate that LBW pigs have developed different behavioural strategies with respect to decision-making. We propose that this is guided by changes in emotionality in LBW piglets, and we provide behavioural evidence of increased negative affect in LBW piglets.
