Title: Growing out of your own mind: Reexamining the development of the self-other difference in the unexpected contents task
The unexpected contents task is a well-established measure for studying young children's developing theory of mind. The task measures whether children understand that others have a false belief about a deceptive container and whether children can track the representational change in their own beliefs about the container's contents. Performance on both questions improves between the ages of 3 and 4. A previous meta-analysis (Wellman, Cross, & Watson, 2001) found little evidence for a difference in children's responses on these questions, but did not investigate the weak effect size that was reported for the interaction between age and question type. The two meta-analyses reported here update the literature review, and find a more robust interaction between question type and age. Three-year-olds showed better performance on questions about their own representational change than others' false belief, while older children showed the reverse pattern. A mega-analysis of a sample of over 1200 children between the ages of 36–60 months then showed the same result. This response pattern requires novel theoretical interpretations, which include reframing the development of children's understanding of false belief.  more » « less

  1. Abstract Despite increasing racial diversity in the United States, and the particular growth of multiracial populations, questions about how children perceive others’ (bi)racial identities remain poorly understood. In two preregistered studies, we asked White and racially minoritized American children (N = 157; 4–11‐years old) and White and multiracial adults (N = 226) how acceptable it was for monoracial people (Black or White; Study 1) and/or biracial people (Black–White; Studies 1 and 2) to claim either a monoracial or biracial identity. Consistent with past research with adults, children said that monoracial people should claim (only) the monoracial identity which matched their ancestry. Judgements about biracial identity were more variable. White and multiracial adults (Study 2) reported that biracial targets could claim a racial identity that matched either or both of their parents, with biracial claims being evaluated most positively. Exploratory analyses on children's judgements about biracial people's identity claims (Study 1) revealed different patterns of development for White children and children from minoritized backgrounds. Whereas White children became more likely with age to report that all identity claims were acceptable, children from racially minoritized groups became more likely with age to endorse biracial targets who claimed a biracial identity. These findings suggest that children's own racial background and age may have a larger impact on their perceptions of biracial people's identities, compared to their perceptions of monoracial people's identities.

  2. ABSTRACT In child sexual abuse (CSA) testimony, attorneys may ask children questions containing pronoun anaphora (e.g., “Where was your Dad?” “What did he do?”heis a pronoun anaphora for referent,Dad). To answer these questions, children must recall the pronoun's referent and appropriate answer to the question. This may be too complex a cognitive task for young children, especially when there are multiple question‐and‐answer (Q–A) turns between the referent and pronoun, leading to misunderstanding. We examined Q–A pairs containing pronouns in 40 CSA testimonies of 5 to 10‐year‐olds. Many attorneys' questions (24%) contained pronouns. Attorneys averaged 4.11 Q–A turns between the referent and pronoun. With each additional Q–A turn, the likelihood of misunderstanding increased. Children's age was also associated with a significant decrease in misunderstanding, meaning older children exhibited fewer misunderstandings. To reduce misunderstanding, those questioning children should clarify the referent quickly when their question contains pronoun anaphora.

  3. Abstract Divergent cultural, religious, and ideological beliefs and practices are often challenging to contemplate and difficult to accept when they conflict with an individual’s own convictions and way of life. The recognition that children and adolescents grow up in an increasingly diverse world has led to a general interest in fostering tolerance. In this article, we discuss three central questions on tolerance and related research. First, we consider age-related patterns of responses toward tolerance of diversity and whether they depend on the type of dissenting beliefs and practices children are asked to tolerate. Second, we focus on how and why children are asked to be tolerant. Third, we discuss the boundaries of tolerance—the reasons and conditions that make tolerance less likely. Overall, we conclude that tolerance and intolerance can occur at all ages and depend on what, how, why, and when individuals are asked to tolerate belief discrepancy and dissenting practices.

  4. Hispanic and Latinx individuals represent one of the largest and fastest growing ethnic groups in the United States. Yet research has not investigated whether young children hold essentialist beliefs about this prevalent social category. The present study addressed this issue by examining whether children used this ethnic category to make inductive inferences about novel individuals, one dimension of essentialism. A total of 108 children, 5 to 7 years of age (54 female; 56 Hispanic, 46 non‐Hispanic), completed a forced‐choice inference task. Children did not expect members of the same ethnic group to share properties, and this did not vary with their own ethnic group membership. This suggests that in the US, the belief that ethnicity is causally informative undergoes a protracted developmental trajectory, as has been observed for essentialist beliefs about race.

  5. Abstract The COVID-19 pandemic and ensuing lockdowns led to sweeping changes in the everyday lives of children and families, including school closures, remote work and learning, and social distancing. To date no study has examined whether these profound changes in young children’s day to day social interactions impacted the development of social cognition skills in early childhood. To address this question, we compared the performance of two cohorts of 3.5- to 5.5-year-old children tested before and after the COVID-19 lockdowns on several measures of false-belief understanding, a critical social cognition skill that undergoes important developments in this age range. Controlling for age and language skills, children tested after the pandemic demonstrated significantly worse false-belief understanding than those tested before the pandemic, and this difference was larger for children from lower socioeconomic status (SES) backgrounds. These results suggest that the pandemic negatively impacted the development of social cognition skills in early childhood, especially for lower SES children.
