Measuring implicit attitudes of 4-year-olds: The Preschool Implicit Association Test

Beyond stereotypes: The role of exposure in reshaping Children's biases towards women as coaches in sports

The underrepresentation of women in sports coaching, linked to discrimination and bias may, according to contact theory, be mitigated by increasing the visibility of women coaches, especially among children. Our study examined whether young athletes exposed to women coaches affected their explicit and implicit biases compared to unexposed peers. Seventy-five children aged between 4 and 17 years were evaluated using two explicit attitude measures and an Implicit Association Task. Results indicated that participants with women coach experience were more explicitly satisfied with woman coaches, preferred them more as potential coaches, and associated men with sports less than those without such exposure. Whilst exposure and implicit bias significantly predicted explicit satisfaction, exposure did not moderate the bias relationship. This suggests that exposure to women coaches reduces negative attitudes in young athletes but does not significantly affect the underlying influence of implicit biases, indicating a need for more comprehensive strategies to address gender inequalities in sports coaching.

Gender stereotypes in preschoolers' mental rotation

The investigation of gender stereotypes constitutes a relevant approach to understanding the development of spatial ability and sex differences in the domain. This was the first study concerned with the presence of implicit and explicit gender stereotypes about spatial ability, and their potential relation to spatial task performance, in preschool-aged children. Our full sample consisted of 138 4- to 6-year-old kindergarten children. The experimental procedure consisted of three parts. Children completed an implicit association task, a short questionnaire on explicit stereotypes, and a chronometric mental rotation task. Preschool-aged children held explicit gender stereotypes about spatial ability linking it to boys rather than girls. Boys exhibited stronger stereotypes in this regard than girls. We also found evidence for the presence of implicit stereotypes. However, implicit stereotypes were not found in sub-group analyses. No clear relationship between stereotypes and mental rotation performance emerged, but our results suggest that implicit stereotyping affected mental rotation accuracy differently in girls compared with boys. Our main conclusion was that children already hold stereotypic beliefs about spatial ability at preschool age. There did not seem to be a relationship of stereotyping with spatial ability at this age.

The visual analogue scale as a child-friendly measure of the unhealthy = tasty intuition

Worldwide, obesity is a growing concern. The implicit belief that healthiness and tastiness in food are inversely related (the Unhealthy = Tasty Intuition or UTI) decreases healthy food consumption and increases the risk of obesity. Since also childhood obesity has increased at an alarming rate and a large component of adult obesity is established during childhood, questions about children's own food beliefs and preferences are important. However, methods currently used to assess the UTI are either unvalidated Likert scales or implicit measures that are time intensive and too complex to be used for children. Two studies presented here offer an alternative measurement - the simple visual analogue scale. The findings show that this measure is more effective in predicting dietary quality in adults and the frequency of healthy food consumption in children compared to more traditional measures. This simple and effective tool could be used by academics and health practitioners alike to better understand children's food beliefs at an early age, which is a critical step when addressing the increasing obesity problem.

Am I a good person? Academic correlates of explicit and implicit self-esteem during early childhood

Implicit and explicit self-esteem are not commonly measured in the same children. Using a cross-sectional design, data from 354 Croatian children (184 girls) in Grade 1 (Mage  = 7.55 years) and Grade 5 (Mage  = 11.58 years) were collected in Spring 2019. All children completed explicit and implicit self-esteem measures; math and language grades were obtained. For the explicit measure, older children showed lower self-esteem than younger children, and girls showed lower self-esteem than boys. For the implicit measure, there were no age effects, and girls showed higher self-esteem than boys. Although both types of self-esteem were positively associated with academic achievement, implicit self-esteem was associated more strongly with language than with math achievement. Discussion is provided about why self-esteem relates to academic achievement during childhood.

Does extended experience with other-race nannies predict racial bias in the preschool years?

Most existing studies on racial bias reduction have used short-term interracial interaction interventions with fleeting effects. The current natural experiment examined whether daily interactions with other-race nannies relate to reduced racial bias in the preschool years. We capitalized on a unique child-rearing situation in Singapore whereby children are often cared for by other-race nannies since infancy. Singaporean Chinese 3- to 6-year-olds (N = 100) completed explicit and implicit racial bias measures assessing their preferential bias favoring own-race adults over adults of their nannies' race. Differential findings were obtained for children's explicit and implicit racial bias. Extensiveness, but not mere presence, of other-race nanny experience was associated with lower levels of explicit racial bias in children. In contrast, neither presence nor extensiveness of other-race nanny experience was associated with children's implicit racial bias. Together, these findings suggest that long-term and extensive contact with an other-race caregiver could have subtle mitigating effects on children's explicit, but not implicit, racial bias.

The role of early intergroup experiences for identification with all humanity in adulthood

Identification with all humanity (IWAH), defined as a bond with and concern for people all over the world, predicts concern for global problems, commitment to human rights, and prosocial activities. However, it is still unknown how such a broad social identification develops and if early experiences play any role. Two studies explored the role of diverse childhood and adolescence intergroup experiences in predicting IWAH in adulthood. We focused on experiences such as being raised in diversity and having intergroup friends, helping or being helped by various others, and having experiences leading to re- or de-categorization, and introduced a new Childhood/Adolescent Intergroup Experiences (CAIE) scale. Study 1 (N = 313 U.S. students, M age = 21) and Study 2 (N = 1,000, a representative Polish sample, M age = 47) found that this kind of intergroup experiences during childhood and adolescence predicted IWAH beyond the effects of its other known predictors, such as empathy, openness to experience, universalism, right-wing authoritarianism, social dominance orientation or ethnocentrism. These results, obtained on various samples and in countries with different ethno-cultural contexts, point to potential ways of enlarging IWAH during childhood and adolescence.

Adolescents’ implicit attitudes towards people with immigrant background: Differences and correlates

People with an immigrant background can be affected by stereotypes and discrimination. As adolescence is an important developmental stage, this study investigated whether adolescents hold (negative) implicit attitudes towards people with Turkish immigrant background and whether adolescents differ in the extent of attitudes. Additionally, the relevance of perceived discrimination, identification with culture of residence, motivation to act without predjudice, and quality and quantity of contact to people with Turkish immigrant background for the extent of implicit attitudes was analysed. Analyses are based on 244 adolescents (60.7% female, 1.6% diverse; 13.1% with Turkish immigrant background, 16.8% with immigrant background other than Turkish) who participated in an online study. An implicit association test revealed that negative implicit attitudes towards people with a Turkish immigrant background were present among adolescents. Unlike adolescents with a Turkish immigrant background, adolescents without immigrant background and with immigrant background other than Turkish hold negative implicit attitudes on average. For the total sample, it was found that low perceived discrimination was related to negative implicit attitudes. The results are discussed with respect to substantive and methodological aspects. Implications for research and practice are derived.

Individuating multiple (not one) persons reduces implicit racial bias

Individuation training that helps humans see multiple other-race targets as distinct rather than as interchangeable can reduce children’s implicit racial bias in the form of more negative other-race associations than own-race associations. However, little is known about which aspects of these interventions are critical for their effectiveness. The present research examines whether children need to learn to differentiate among multiple other-race individuals for these interventions to reduce their level of implicit racial bias, or whether differentiating a single other-race individual is sufficient. We addressed this question among 4-to-6-year-old Chinese children (N = 66, 31 girls) who engaged in coordinated movement with Black instructors for 2 min. There were two between-subject conditions: in a differentiation condition, there were four different Black instructors, and children had to learn to tell them apart, and in a no-differentiation condition, there was only one Black instructor. Implicit bias was measured using the IRBT, an implicit association test that was developed based on the IAT but is appropriate for young children. We found a reduction in implicit bias against Black people after this interaction in the differentiation condition, but not in the no-differentiation condition. These findings suggest that learning to differentiate among multiple other-race individuals plays a critical role in reducing children’s implicit racial bias.

The Dynamics of Implicit Intergroup Biases of Victims and Ex-combatants in Post-conflict Scenarios

Strong group identities arise in intergroup conflict scenarios and perpetuate sectarian violence even in post-conflict scenarios. In particular, out-group negative implicit associations are predictors of decreased intergroup forgiveness, as well as increased distrust and aggression against the out-group. Thus, the presence of implicit intergroup (i.e., ex-combatants and victims) biases seems to be a relevant factor in post-conflict scenarios. Here, we aimed to explore whether negative biases toward the out-group are boosted by (a) previous exposure to conflict violence or (b) identification with an armed violent group. One hundred and twenty-eight participants, 65 ex-combatants from Colombian guerrillas and 63 victims of the armed conflict, were assessed with a modified version of the implicit association test (IAT). Our results revealed that the victim group showed a significant negative bias against ex-combatants. However, no bias toward the out-group (i.e., victims) or in-group favoritism was observed in the ex-combatant group. Similarly, we found that IAT scores were not associated with sociodemographical variables (i.e., sex, years of education, or type of dwelling), the levels of combat exposure, victimization armed-conflict-related experiences, or child abuse antecedents. Our results showed an unexpected lack of in-group bias in ex-combatants, potentially triggered by the effect of current demobilization and reintegration processes. Thus, negative associations with the out-group will persist in the framework of societal condemnation of the out-group. In contrast, these negative biases will tend to be abolished when entering in conflict with larger societal reintegration processes. The results reinforce the idea that reintegration may benefit from interventions at the societal level, including all actors of the conflict. In addition, our findings highlight the importance of implementing victim interventions aimed at reducing stigma and revengeful actions in spaces of collective disarmament.

Implicit-Bias Remedies: Treating Discriminatory Bias as a Public-Health Problem

Accumulated findings from studies in which implicit-bias measures correlate with discriminatory judgment and behavior have led many social scientists to conclude that implicit biases play a causal role in racial and other discrimination. In turn, that belief has promoted and sustained two lines of work to develop remedies: (a) individual treatment interventions expected to weaken or eradicate implicit biases and (b) group-administered training programs to overcome biases generally, including implicit biases. Our review of research on these two types of sought remedies finds that they lack established methods that durably diminish implicit biases and have not reproducibly reduced discriminatory consequences of implicit (or other) biases. That disappointing conclusion prompted our turn to strategies based on methods that have been successful in the domain of public health. Preventive measures are designed to disable the path from implicit biases to discriminatory outcomes. Disparity-finding methods aim to discover disparities that sometimes have obvious fixes, or that at least suggest where responsibility should reside for developing a fix. Disparity-finding methods have the advantage of being useful in remediation not only for implicit biases but also systemic biases. For both of these categories of bias, causes of discriminatory outcomes are understood as residing in large part outside the conscious awareness of individual actors. We conclude with recommendations to guide organizations that wish to deal with biases for which they have not yet found solutions.

Unconscious associations between stressor type and ability to cope: An experimental approach using ancient and modern sources of stress

Objectives

Work has emerged that suggests it is salient and feasible to include a chronological approach to the taxonomy of stress. The ability to make an explicit distinction between ancient stressors (AS) and modern stressors (MS) has been reported in young and older adults; AS have been associated with greater ability to cope and MS with poorer health outcomes. Whether these explicit distinctions exist at an implicit, unconscious level, has yet to be determined.

Design

A quantitative design employed a computer‐based Implicit Association Test (IAT) to examine implicit associations between AS/MS and coping appraisal.

Methods

One hundred adults (75 females) aged 18–58 years (M = 28.27 years, SD = 10.02) completed the AS/MS IAT, to compare reaction time (RT) and accuracy between consistent pairs (AS/ability to cope; MS/inability to cope) and inconsistent pair responses (AS/inability to cope; MS/ability to cope); followed by an explicit self‐report questionnaire.

Results

Repeated measures ANCOVAs, controlling for sex and age, revealed significant main effects of faster RT and higher accuracy in responses for consistent than inconsistent pairs. Adult participants made implicit associations indicating an unconscious AS and MS distinction. Using the D algorithm, a univariate ANCOVA and independent t‐tests found that males, compared to females, showed a stronger implicit preference for consistent than inconsistent pairs.

Conclusions

Findings suggest an implicit association between ancient and modern stressors and perceived coping ability. Utilizing a chronological taxonomy for understanding evolutionary origins that drive individual’s responses to stress has implications for developing effective coping strategies to improve health outcomes.

What Might Books Be Teaching Young Children About Gender?

We investigated how gender is represented in children's books using a novel 200,000-word corpus comprising 247 popular, contemporary books for young children. Using adult human judgments and word co-occurrence data, we quantified gender biases of words in individual books and in the whole corpus. We found that children's books contain many words that adults judge as gendered. Semantic analyses based on co-occurrence data yielded word clusters related to gender stereotypes (e.g., feminine: emotions; masculine: tools). Co-occurrence data also indicated that many books instantiate gender stereotypes identified in other research (e.g., girls are better at reading, and boys are better at math). Finally, we used large-scale data to estimate the gender distribution of the audience for individual books, and we found that children are more often exposed to stereotypes for their own gender. Together, the data suggest that children's books may be an early source of gender associations and stereotypes.

Reducing Prejudice Through Promoting Cross-Group Friendships

Around the globe, individuals are affected by exclusion, discrimination, and prejudice targeting individuals from racial, ethnic, and immigrant backgrounds as well as crimes based on gender, nationality, and culture (United Nations General Assembly, 2016). Unfortunately, children are often the targeted victims (Costello & Dillard, 2019). What is not widely understood is that the intergroup biases underlying systemic racism start long before adulthood with children displaying notable signs of intergroup bias, sometimes before entering grade school. Intergroup bias refers to the tendency to evaluate members of one’s own group more favorably than someone not identified with one’s group and is typically associated with prejudicial attitudes. Children are both the victims and the perpetrators of bias. In this review, we provide evidence of how biases emerge in childhood, along with an analysis of the significant role of intergroup friendships on enhancing children’s well-being and reducing prejudice in childhood. The review focuses predominantly on the context of race, with the inclusion of several other categories, such as nationality and religion. Fostering positive cross-group friendships in childhood helps to address the negative long-term consequences of racism, discrimination, and prejudice that emerges in childhood and continues through to adulthood.

Best research practices for using the Implicit Association Test

Interest in unintended discrimination that can result from implicit attitudes and stereotypes (implicit biases) has stimulated many research investigations. Much of this research has used the Implicit Association Test (IAT) to measure association strengths that are presumed to underlie implicit biases. It had been more than a decade since the last published treatment of recommended best practices for research using IAT measures. After an initial draft by the first author, and continuing through three subsequent drafts, the 22 authors and 14 commenters contributed extensively to refining the selection and description of recommendation-worthy research practices. Individual judgments of agreement or disagreement were provided by 29 of the 36 authors and commenters. Of the 21 recommended practices for conducting research with IAT measures presented in this article, all but two were endorsed by 90% or more of those who felt knowledgeable enough to express agreement or disagreement; only 4% of the totality of judgments expressed disagreement. For two practices that were retained despite more than two judgments of disagreement (four for one, five for the other), the bases for those disagreements are described in presenting the recommendations. The article additionally provides recommendations for how to report procedures of IAT measures in empirical articles.

Factors Affecting the Perception of Disability: A Developmental Perspective

Perception of disability is an important construct affecting not only the well-being of individuals with disabilities, but also the moral compass of the society. Negative attitudes toward disability disempower individuals with disabilities and lead to their social exclusion and isolation. By contrast, a healthy society encourages positive attitudes toward individuals with disabilities and promotes social inclusion. The current review explored disability perception in the light of the in-group vs. out-group dichotomy, since individuals with disabilities may be perceived as a special case of out-group. We implemented a developmental approach to study perception of disability from early age into adolescence while exploring cognitive, affective, and behavioral components of children’s attitudes. Potential factors influencing perception of disability were considered at the level of society, family and school environment, and the individual. Better understanding of factors influencing the development of disability perception would allow the design of effective interventions to improve children’s attitudes toward peers with disabilities, reduce intergroup biases, and promote social inclusion. Based on previous research in social and developmental psychology, education, and anthropology, we proposed an integrative model that provides a conceptual framework for understanding the development of disability perception.

Another step to school inclusion: Development and validation of the Children's Attitudes Toward Autism Questionnaire

LAY ABSTRACT

Research has shown that negative attitudes toward a different child can appear very early in development. Unfortunately, these negative attitudes are one of the most important barriers to the school inclusion of children with autism. Despite the increasing amount of research, no tool reliably measures these attitudes among young students. The objective of this study was to develop and validate a questionnaire (Children's Attitudes Toward Autism Questionnaire) to evaluate attitudes of students in elementary school toward their peers with autism. Elementary school students (N = 204) completed the Children's Attitudes Toward Autism Questionnaire and two other scales assessing behavioral intentions toward peers with a mental disability (Shared Activities Questionnaire-B) and familiarity with disability and autism. Results first showed that the Children's Attitudes Toward Autism Questionnaire reliably measured the concept of attitude through three sub-dimensions (namely, the cognitive, affective, and behavioral dimensions). Second, analyses confirmed that the Children's Attitudes Toward Autism Questionnaire corresponds with previous knowledge on this topic, namely, that attitudes were more positive in girls, older children, and children familiar with disability. In conclusion, the Children's Attitudes Toward Autism Questionnaire is the first scale (1) to assess all the dimensions of attitudes toward autism among elementary school children (from the age of 6 years old) and (2) to show theoretical and statistical relevance. From now on, the Children's Attitudes Toward Autism Questionnaire can be used to assess attitudes of young children toward their peers with autism. This is an important step forward, in particular for evaluating the effects of anti-stigma programs that are increasingly implemented in schools.

Group status rapidly shapes preschoolers' social judgments in minimal group settings

Previous developmental research has consistently detected the presence of an explicit and implicit ingroup preference among preschoolers. More recent research has also demonstrated that this general ingroup bias is influenced by perceived social status when "real" groups are involved (i.e., groups with a previous history of interactions). Indeed, ingroup bias is significantly tempered among low-status group members. The main aim of the current study was to further investigate the role of social status by assessing both implicit and explicit intergroup attitudes in the context of newly formed groups. More specifically, children were randomly assigned to one of two fictitious groups on the basis of trivial criteria, thereby forming the so-called "minimal" groups. To manipulate group status, participants were then informed that one specific group-either the ingroup or the outgroup-was typically better than the other group during competitions. Finally, implicit and explicit intergroup attitudes were assessed. Overall, results showed that children rapidly formed implicit and explicit intergroup attitudes toward newly formed groups. Most important, the perceived status of the groups modulated such intergroup attitudes. Indeed, on both types of measures, ingroup bias emerged when the ingroup was associated with a high status, whereas it disappeared when the ingroup was in a low-status position.

Dopaminergic and neurotrophic genetic polymorphisms modulate the implicit gender-science stereotype

Genetic approaches to both the gender-science stereotype and implicit social cognition have received increasing attention in recent years. We explored whether single nucleotide polymorphisms (SNPs) in dopaminergic and neurotrophic systems (i.e., COMT, BDNF genotypes) explain variations in the implicit gender-science stereotype. We genotyped 413 adolescents and assessed their implicit gender-science stereotype with the Implicit Association Test. Replication on a subsample (N = 312) was conducted 2 years later. Results showed that SNP-level variations within the COMT and BDNF genes were consistently associated with the implicit gender-science stereotype in both investigations. These findings suggest that variants in the COMT and BDNF genes may contribute to the variation of implicit gender-science stereotype.

The self-esteem implicit association test is valid: Evidence from brain activity

A distinct challenge of implicit self-esteem research is the dubious validity of measures for implicit self-esteem. We conducted two event-related potential (ERP) studies to examine whether implicit self-esteem measured by the Implicit Association Test (IAT) actually reflects the automatic self-evaluation. We adopted the regular IAT and the Go/No-go Association Task (GNAT), respectively, to measure implicit self-esteem in two studies. We focused on the P300 that reflects the stimulus evaluation process. Study 1 revealed that participants responded faster to self pairing with good than to self pairing with bad whereas self pairing with bad elicited a delayed P300 compared with self pairing with good. Study 2 replicated these findings and further highlighted that the index of implicit self-esteem based on reaction time is correlated with that based on P300 latency. Our results suggest that implicit self-esteem assessed by the IAT measures automatic self-evaluation, thus providing neural evidence for the validity of implicit self-esteem.

What Can Experimental Studies of Bias Tell Us About Real-World Group Disparities?

This article questions the widespread use of experimental social psychology to understand real-world group disparities. Standard experimental practice is to design studies in which participants make judgments of targets who vary only on the social categories to which they belong. This is typically done under simplified decision landscapes and with untrained decision makers. For example, to understand racial disparities in police shootings, researchers show pictures of armed and unarmed Black and White men to undergraduates and have them press "shoot" and "don't shoot" buttons. Having demonstrated categorical bias under these conditions, researchers then use such findings to claim that real-world disparities are also due to decision-maker bias. I describe three flaws inherent in this approach, flaws which undermine any direct contribution of experimental studies to explaining group disparities. First, the decision landscapes used in experimental studies lack crucial components present in actual decisions (Missing Information Flaw). Second, categorical effects in experimental studies are not interpreted in light of other effects on outcomes, including behavioral differences across groups (Missing Forces Flaw). Third, there is no systematic testing of whether the contingencies required to produce experimental effects are present in real-world decisions (Missing Contingencies Flaw). I apply this analysis to three research topics to illustrate the scope of the problem. I discuss how this research tradition has skewed our understanding of the human mind within and beyond the discipline and how results from experimental studies of bias are generally misunderstood. I conclude by arguing that the current research tradition should be abandoned.

Cognitive flexibility and parental education differentially predict implicit and explicit racial biases in bilingual children

Prior research has suggested that bilingual children demonstrate reduced social bias relative to their monolingual peers. In particular, they exhibit less implicit bias against racial outgroups. However, the cognitive determinants of racial bias in bilingual children remain unclear. In the current study, relationships between racial bias and three cognitive factors (inhibitory control, cognitive flexibility, and perspective-taking ability), along with language proficiency and parental education, were investigated in a sample of bilingual preschoolers (N = 55). Children were bilingual learners of English and Mandarin. Results demonstrated that implicit bias was predicted by cognitive flexibility, independent of variation in inhibitory control, second language vocabulary, perspective taking, and parental education. In contrast, explicit bias was predicted by parental education alone and not by cognitive or linguistic factors. Findings suggest that increased cognitive flexibility, often thought to be an outgrowth of bilingual experience, may also be associated with a reduction in implicit bias. Findings are discussed in terms of specific mechanisms that may link cognitive factors, bilingualism, and racial bias.

Age Invariance in Implicit Bias: Alternative Perspectives and Their Implications for the Development of Implicit Cognition

Current theories of social cognition assume that implicit bias is influenced by early socialization experiences. To the extent that implicit biases reflect traces of past experiences, they should form slowly over time and grow with repeated experience. However, most research examining implicit bias in children indicates that levels of bias do not vary across age groups (i.e., age invariance). This article reviews the dominant theoretical interpretation of age invariance in implicit bias and considers alternative interpretations for these findings in light of several methodological and theoretical limitations. Specifically, the available evidence cannot distinguish between the effects of cohort versus development, category versus exemplar, attitude activation versus application, ingroup versus outgroup evaluation, or attitude-versus control-oriented processes. When considered from a developmental perspective, these issues suggest plausible alternative interpretations of age invariance, with important implications for understanding the mechanisms underlying the formation of implicit cognition and theories of implicit cognition.

Enhancing same-gender imitation by highlighting gender norms in Chinese pre-school children

Children selectively imitate in-group over outgroup individuals under certain experimental conditions. We investigated whether this bias applies to gender in-groups in China. Three- and five-year-olds were shown how to operate novel objects by same-gender and opposite-gender models. Results indicate that the combination of verbally highlighting the gender identity of the model (e.g., 'I am a girl') and making gender norms explicit (e.g., 'girls play this way') significantly enhances high-fidelity imitation. This 'double social effect' was more robust in 5-year-olds than 3-year-olds. Our results underscore how language about gender and the norms for gender-based groups influence behavioural imitation. The pattern of findings enhances our knowledge about pre-schoolers' social learning and imitation as well as the powerful influence of language and group norms on children's voluntary actions and learning.

Medically unexplained symptoms in children and adolescents: Illness-related self-concept and parental symptom evaluations

BACKGROUND AND OBJECTIVES

According to cognitive-behavioral models, illness-related symptom evaluations and self-concepts play a pivotal role in the development and maintenance of medically unexplained somatic symptoms (MUS). However, illness-related cognitions related to MUS have rarely been studied in children/adolescents and their parents.

METHODS

Seventy-eight children and adolescents (M = 14.2 years; 59% female) performed two versions of the Implicit Association Test (IAT) to measure the implicit illness-related and the implicit anxiety-related self-concept. Illness-related evaluations of unspecific symptoms were assessed via the Health Norms Sorting Task (HNST), and MUS as well as characteristics of somatic symptom disorder (SSD) via questionnaires.

RESULTS

MUS were significantly positively associated with the explicit (r = 0.30, p < .01) and implicit illness-related self-concept (r = 0.24, p = .04), but not with the anxiety-related self-concept (r = 0.15, p = .18). The implicit illness-related self-concept explained incremental variance in MUS (ΔR² = 0.05, p = .04) beyond the explicit illness-related self-concept. Regarding health anxiety, parental illness-related symptom evaluations moderated the relationship between child-reported severity of MUS and health anxiety (B = 0.12, p < .01).

LIMITATIONS

Some measures have been adapted for childhood and adolescence, but validations on larger samples are still pending.

CONCLUSIONS

A disorder-specific self-concept of being ill, as well as parental symptom evaluations, seem to play an essential role in MUS and health anxiety in childhood and adolescence. Due to the importance of the top-down processes found here, the findings are in line with current predictive coding models of somatic symptom perception.

Children's and parents' looking preferences to gender-typed objects: Evidence from eye tracking

Differences between children's and parents' implicit and explicit gender stereotypes were investigated in two experiments. For the first time, the visual world paradigm compared parents' and 7-8-year-old children's looking preferences toward masculine- and feminine-typed objects stereotypically associated with a story character's gender. In Experiment 1 participants listened to sentences that included a verb that inferred intentional action with an object (e.g., "Lilly/Alexander will play with the toy"), and in Experiment 2 the verb was replaced with a neutral verb (e.g., "Lilly/Alexander will trip over the toy"). A questionnaire assessed participants' explicit gender stereotype endorsement (and knowledge [Experiment 2]) of children's toys. Results revealed that parents and children displayed similar implicit stereotypes, but different explicit stereotypes, to one another. In Experiment 1, both children and parents displayed looking preferences toward the masculine-typed object when the story character was male and looking preferences toward the feminine-typed object when the character was female. No gender effects were found with a neutral verb in Experiment 2, reinforcing the impact of gender stereotypes on implicit processing and showing that the effects are not simply driven by gender stereotypic name-object associations. In the explicit measure, parents did not endorse the gender stereotypes related to toys but rather appeared to be egalitarian, whereas children's responses were gender stereotypic.

Acquiring group bias: Observing other people's nonverbal signals can create social group biases

Evidence of group bias based on race, ethnicity, nationality, and language emerges early in the life span. Although understanding the initial acquisition of group bias has critical theoretical and practical implications, precisely how group biases are acquired has been understudied. In two preregistered experiments, we tested the hypothesis that generalized social group biases can be acquired through exposure to positive nonverbal signals directed toward a novel adult from one group and more negative nonverbal signals directed toward a novel adult from another group. We sought to determine whether children would acquire global nonverbal signal-consistent social group biases that extended beyond their explicit social preferences, by measuring children's preferences, imitation, and behavioral intentions. Supporting our preregistered hypotheses, preschool-age participants favored small and large groups whose member received positive nonverbal signals, relative to groups whose member received more negative nonverbal signals. We also replicated prior work indicating that children will acquire individual target biases from the observation of biased nonverbal signals. Here we make the case that generalized social group biases can be rapidly and unintentionally transmitted on the basis of observational learning from nonverbal signals.

Differential developmental courses of implicit and explicit biases for different other-race classes

We investigated the developmental courses of both implicit and explicit racial biases in relation to the perceived social status of outgroups. We did so by assessing these biases among Chinese participants (N = 200, age range from 4- to 19-year-olds) toward 2 different other-race groups that differ in terms of perceived social status (i.e., Whites and Blacks). At the youngest age, children showed both implicit anti-White and anti-Black bias at similar levels. However, these biases had different patterns of age-related change: implicit anti-Black bias remained strong and stable over time, whereas implicit anti-White bias declined after age 10. For explicit bias, children showed a decline in anti-Black and anti-White bias. Implicit and explicit biases were uncorrelated at all ages. The observed age-related changes demonstrate that it is possible for patterns of biases toward different races to diverge with age, and that perceived social status may contribute to the differential developmental patterns.

The Protracted Maturation of Associative Layer IIIC Pyramidal Neurons in the Human Prefrontal Cortex During Childhood: A Major Role in Cognitive Development and Selective Alteration in Autism

The human specific cognitive shift starts around the age of 2 years with the onset of self-awareness, and continues with extraordinary increase in cognitive capacities during early childhood. Diffuse changes in functional connectivity in children aged 2-6 years indicate an increase in the capacity of cortical network. Interestingly, structural network complexity does not increase during this time and, thus, it is likely to be induced by selective maturation of a specific neuronal subclass. Here, we provide an overview of a subclass of cortico-cortical neurons, the associative layer IIIC pyramids of the human prefrontal cortex. Their local axonal collaterals are in control of the prefrontal cortico-cortical output, while their long projections modulate inter-areal processing. In this way, layer IIIC pyramids are the major integrative element of cortical processing, and changes in their connectivity patterns will affect global cortical functioning. Layer IIIC neurons have a unique pattern of dendritic maturation. In contrast to other classes of principal neurons, they undergo an additional phase of extensive dendritic growth during early childhood, and show characteristic molecular changes. Taken together, circuits associated with layer IIIC neurons have the most protracted period of developmental plasticity. This unique feature is advanced but also provides a window of opportunity for pathological events to disrupt normal formation of cognitive circuits involving layer IIIC neurons. In this manuscript, we discuss how disrupted dendritic and axonal maturation of layer IIIC neurons may lead into global cortical disconnectivity, affecting development of complex communication and social abilities. We also propose a model that developmentally dictated incorporation of layer IIIC neurons into maturing cortico-cortical circuits between 2 to 6 years will reveal a previous (perinatal) lesion affecting other classes of principal neurons. This "disclosure" of pre-existing functionally silent lesions of other neuronal classes induced by development of layer IIIC associative neurons, or their direct alteration, could be found in different forms of autism spectrum disorders. Understanding the gene-environment interaction in shaping cognitive microcircuitries may be fundamental for developing rehabilitation and prevention strategies in autism spectrum and other cognitive disorders.

Bias at the intersection of race and gender: Evidence from preschool-aged children

There is ample evidence of racial and gender bias in young children, but thus far this evidence comes almost exclusively from children's responses to a single social category (either race or gender). Yet we are each simultaneously members of many social categories (including our race and gender). Among adults, racial and gender biases intersect: negative racial biases are expressed more strongly against males than females. Here, we consider the developmental origin of bias at the intersection of race and gender. Relying on both implicit and explicit measures, we assessed 4-year-old children's responses to target images of children who varied systematically in both race (Black and White) and gender (male and female). Children revealed a strong and consistent pro-White bias. This racial bias was expressed more strongly for males than females: children's responses to Black boys were less positive than to Black girls, White boys or White girls. This outcome, which constitutes the earliest evidence of bias at the intersection of race and gender, underscores the importance of addressing bias in the first years of life.

Face Processing in Infancy and Beyond: The Case of Social Categories

Prior reviews of infant face processing have emphasized how infants respond to faces in general. This review highlights how infants come to respond differentially to social categories of faces based on differential experience, with a focus on race and gender. We examine six different behaviors: preference, recognition, scanning, category formation, association with emotion, and selective learning. Although some aspects of infant responding to face race and gender may be accounted for by traditional models of perceptual development, other aspects suggest the need for a broader model that links perceptual development with social and emotional development. We also consider how responding to face race and gender in infancy may presage responding to these categories beyond infancy and discuss how social biases favoring own-race and female faces are formed.

Explicit and Implicit Positive Illusory Bias in Children With ADHD

OBJECTIVE

Children with ADHD overestimate their own social and behavioral competence when using explicit self-report measures, a phenomenon known as Positive Illusory Bias (PIB). This study examined whether children with ADHD show PIB when self-perceptions are measured implicitly, reflecting associations that are relatively difficult to consciously control.

METHOD

Participants were 23 children (ages 6.8-9.8) with ADHD and 55 typically developing (TD) children. Children's explicit self-perceptions of competence were measured via self-report on the Self-Perception Profile for Children; their implicit associations were assessed using an Implicit Association Test. Parent and teacher ratings formed an adult-reported composite indicator of children's competence, to which children's self-perceptions were compared.

RESULTS

Children with ADHD overestimated their competence as compared with adult-informant reports on both explicit and implicit measures, whereas TD children tended to be accurate.

CONCLUSION

Inflated self-perceptions in children with ADHD may exist on an implicit level outside of conscious awareness.

Perceptual individuation training (but not mere exposure) reduces implicit racial bias in preschool children

Two studies with preschool-age children examined the effectiveness of perceptual individuation training at reducing racial bias (Study 1, N = 32; Study 2, N = 56). We found that training preschool-age children to individuate other-race faces resulted in a reduction in implicit racial bias while mere exposure to other-race faces produced no such effect. We also showed that neither individuation training nor mere exposure reduced explicit racial bias. Theoretically, our findings provide strong evidence for a causal link between individual-level face processing and implicit racial bias, and are consistent with the newly proposed perceptual-social linkage hypothesis. Practically, our findings suggest that offering children experiences that allow them to increase their expertise in processing individual other-race faces will help reduce their implicit racial bias.

Inmigración en la escuela: caracterización del prejuicio hacia escolares migrantes en Chile

Chile ha tenido un incremento sostenido de población inmigrante, pero poco se conoce sobre su impacto en el sistema escolar. Por medio de metodologías mixtas, se recolectó información acerca de las percepciones y prejuicios que estudiantes y profesores, de comunas de la Región Metropolitana de Chile, poseen respecto de la inmigración y la multiculturalidad. Este artículo caracteriza aspectos asociados al prejuicio existente hacia los inmigrantes en el sistema escolar, tanto a nivel explícito como implícito, corroborando la hipótesis de contacto propuesta por la psicología social; y brindando orientaciones tendientes a potenciar la inclusión de la diversidad cultural en el sistema educacional, tanto a nivel de contexto, políticas como prácticas pedagógicas.

Anxiety disorders, gender nonconformity, bullying and self-esteem in sexual minority adolescents: prospective birth cohort study

BACKGROUND

Sexual minority adolescents (i.e. youth not exclusively heterosexual) report more anxiety than heterosexual youth on symptom questionnaires but no research has used standardised diagnostic tools to investigate anxiety disorder risk. This study uses a UK birth cohort to investigate the risk of anxiety disorders in sexual minority and heterosexual youth using a computerised structured clinical interview and explores the influence of gender nonconformity, bullying and self-esteem.

METHODS

Participants were 4,564 adolescents (2,567 girls and 1,996 boys) from the Avon Longitudinal Study of Parents and Children (ALSPAC). Logistic regression analyses were performed to investigate the association between sexual orientation at 15.5 years and the presence of an anxiety disorder at 17.5 years. Covariates including maternal occupation, ethnicity, mother-reported childhood gender nonconformity at 30, 42 and 57 months, child-reported gender nonconformity at 8 years, child-reported bullying between 12 and 16 years and self-esteem at 17.5 years were added sequentially to regression models.

RESULTS

Sexual minority adolescents (i.e. those not exclusively heterosexual) had higher early childhood gender nonconformity (CGN), lower self-esteem and reported more bullying than adolescents identifying as 100% heterosexual. Minority sexual orientation at 15.5 years was associated with increased risk of an anxiety disorder at 17.5 years for girls (OR 2.55, CI 1.85-3.52) and boys (OR 2.48, CI 1.40-4.39). Adjusting for ethnicity, maternal occupation, mother-reported and child-reported CGN had minimal impact on this association. Adjusting for bullying between 12 and 16 years and self-esteem at 17.5 years reduced the strength of the associations, although the overall association remained significant for both sexes (girls OR 2.14 and boys OR 1.93).

CONCLUSIONS

Sexual minority youth are at increased risk of anxiety disorders relative to heterosexual youth at 17.5 years. Bullying between 12-16 years and lower self-esteem may contribute to this risk.

A Long-Term Effect of Perceptual Individuation Training on Reducing Implicit Racial Bias in Preschool Children

This study tracked the long-term effect of perceptual individuation training on reducing 5-year-old Chinese children's (N = 95, M_age  = 5.64 years) implicit pro-Asian/anti-Black racial bias. Initial training to individuate other-race Black faces, followed by supplementary training occurring 1 week later, resulted in a long-term reduction of pro-Asian/anti-Black bias (70 days). In contrast, training Chinese children to recognize White or Asian faces had no effect on pro-Asian/anti-Black bias. Theoretically, the finding that individuation training can have a long-term effect on reducing implicit racial bias in preschoolers suggests that a developmentally early causal linkage between perceptual and social processing of faces is not a transitory phenomenon. Practically, the data point to an effective intervention method for reducing implicit racism in young children.

Face race processing and racial bias in early development: A perceptual-social linkage

Infants have asymmetrical exposure to different types of faces (e.g., more human than other-species, more female than male, and more own-race than other-race). What are the developmental consequences of such experiential asymmetry? Here we review recent advances in research on the development of cross-race face processing. The evidence suggests that greater exposure to own- than other-race faces in infancy leads to developmentally early perceptual differences in visual preference, recognition, category formation, and scanning of own- and other-race faces. Further, such perceptual differences in infancy may be associated with the emergence of implicit racial bias, consistent with a Perceptual-Social Linkage Hypothesis. Current and future work derived from this hypothesis may lay an important empirical foundation for the development of intervention programs to combat the early occurrence of implicit racial bias.

Racial Categorization Predicts Implicit Racial Bias in Preschool Children

This research investigated the relation between racial categorization and implicit racial bias in majority and minority children. Chinese and Indian 3‐ to 7‐year‐olds from Singapore (N = 158) categorized Chinese and Indian faces by race and had their implicit and explicit racial biases measured. Majority Chinese children, but not minority Indian children, showed implicit bias favoring own race. Regardless of ethnicity, children's racial categorization performance correlated positively with implicit racial bias. Also, Chinese children, but not Indian children, displayed explicit bias favoring own race. Furthermore, children's explicit bias was unrelated to racial categorization performance and implicit bias. The findings support a perceptual–social linkage in the emergence of implicit racial bias and have implications for designing programs to promote interracial harmony.

Is Trypophobia a Phobia?

In the past 10 years, thousands of people have claimed to be affected by trypophobia, which is the fear of objects with small holes. Recent research suggests that people do not fear the holes; rather, images of clustered holes, which share basic visual characteristics with venomous organisms, lead to nonconscious fear. In the present study, both self-reported measures and the Preschool Single Category Implicit Association Test were adapted for use with preschoolers to investigate whether discomfort related to trypophobic stimuli was grounded in their visual features or based on a nonconsciously associated fear of venomous animals. The results indicated that trypophobic stimuli were associated with discomfort in children. This discomfort seemed to be related to the typical visual characteristics and pattern properties of trypophobic stimuli rather than to nonconscious associations with venomous animals. The association between trypophobic stimuli and venomous animals vanished when the typical visual characteristics of trypophobic features were removed from colored photos of venomous animals. Thus, the discomfort felt toward trypophobic images might be an instinctive response to their visual characteristics rather than the result of a learned but nonconscious association with venomous animals. Therefore, it is questionable whether it is justified to legitimize trypophobia.

Self-Concepts, Self-Esteem, and Academic Achievement of Minority and Majority North American Elementary School Children

Minority and majority elementary school students from a Native American reservation (N = 188; K-fifth grade; 5- to 10-year-olds) completed tests of academic self-concepts and self-esteem. School grades, attendance, and classroom behavior were collected. Both minority and majority students exhibited positive self-esteem. Minority students demonstrated lower academic self-concepts and lower achievement than majority students. Two age-related patterns emerged. First, minority students had lower academic achievement than majority students, and this effect was stronger in older (Grades 3-5) than in younger (Grades K-2) students. Second, children's actual achievement was related to their academic self-concepts for older students but more strongly linked to self-esteem in younger students. The authors offer a developmental account connecting students' developing self-representations to their school achievement.
