How special are objects? Children's reasoning about objects, parts, and holes

Discrete physical objects have a special status in cognitive and linguistic development. Infants track and enumerate objects, young children are biased to construe novel words as referring to objects, and, when asked to count an array of items, preschool children tend to count the discrete objects, even if explicitly asked to do otherwise. We address here the question of whether discrete physical objects are the only entities that have this special status, or whether other individuals are salient as well. In two experiments, we found that 3-year-olds are just as good at identifying, tracking, and counting certain nonobject entities (holes in Experiment 1; holes and parts in Experiment 2) as they are with objects. These results are discussed in light of different theories of the nature and development of children's object bias.     

Differences in Internalizing Symptoms Across Specific Ethnic Minority Groups: An Analysis Across Chinese American,Filipino American,Japanese American,Native Hawaiian,and White Youth

Research to date on child and adolescent anxiety and depression have focused predominantly on major ethnic groups. Very few studies to date have been conducted on specific ethnic minority groups and the relatively few studies on these ethnic minority samples have produced mixed findings. The following question therefore still remains: Do specific ethnic subgroups differ with respect to their expression of anxiety and depression? And do these differences differ as a function of reporter type (i.e., youth versus parent)? If the expression of internalizing symptoms differs across specific ethnic subgroups, these differences could inform approaches to assessing and treating these populations. In the current study, we therefore examined ethnic differences in anxiety and depression symptoms in ethnic subgroups. A total of 629 children and adolescents from various public and private schools, aged 8–18 years (M = 12.37, SD = 2.8) and their caregivers completed anxiety and depression scales. Multiple indicators, multiple causes confirmatory factor analysis revealed that the following specific ethic subgroups were associated with significantly greater anxiety and depression relative to Caucasian youth: Chinese American, Filipino American, Japanese American, and Native Hawaiian. These results were found only among parent (but not youth) reports. Age and low SES status was also associated with more internalizing problems among Chinese, Filipino, and Japanese American youth. Implications related to ethnic minority subgroup differences and the role of multi-informant reports in understanding the relationship between anxiety, depression and ethnic minority subgroups are discussed.     

Children's and adults' judgments of equitable resource distributions

This study explored the criteria that children and adults use when evaluating the niceness of a character who is distributing resources. Four- and five-year-olds played the 'Giving Game', in which two puppets with different amounts of chips each gave some portion of these chips to the children. Adults played an analogous task that mimicked the situations presented to children in the Giving Game. For all groups of participants, we manipulated the absolute amount and proportion of chips given away. We found that children and adults used different cues to establish which puppet was nicer: 4-year-olds focused exclusively on absolute amount, 5-year-olds showed some sensitivity to proportion, and adults focused exclusively on proportion. These results are discussed in light of their implications for equity theory and for theories of the development of social evaluation.     

Age Differences Across Adulthood in Interpretations of Situations and Situation–Behaviour Contingencies for Big Five States

In the last two decades, a burgeoning literature has begun to clarify the processes underlying personality traits and momentary trait‐relevant behaviour. However, such work has almost exclusively investigated these questions in young adults. During the same period, much has been learned about adult personality trait development but with scant attention to the momentary processes that contribute to development. The current work connects these two topics, testing developmental questions about adult age differences and thus examining how age matters to personality processes. The study examines how four important situation characteristics are experienced in everyday life and how situations covary with Big Five trait‐relevant behaviour (i.e. situation–behaviour contingencies). Two samples were collected (total N = 316), each assessing three age groups: young, middle‐aged, and older adults. Using experience sampling method, participants completed reports four or five times per day across a representative period of daily life. Results suggested age differences in how situations are experienced on average, in the variability around these average situation experiences, and in situation–behaviour contingencies. The results therefore highlight that, across adulthood, age groups experience chronically different situations, differ in how much the situations they experience vary moment to moment, and differ in how much situation experience predicts their enactment of traits. © 2019 European Association of Personality Psychology     

Survival in Extreme Conditions

This article explores the psychosocial and environmental configurations that might have been responsible for an unusual situation of survival under extreme conditions. A group of 500 civilians (mostly Americans) lived 3 ½ years in a Japanese internment camp in the Philippines during World War II. Although conditions were very harsh, the survival rate of this group was better than expected for a comparable group under normal conditions. Discussion of available demographic, social organizational, and cultural information leads to three hypotheses that might account for this outcome.
