Children's social wariness toward a different-race stranger relates to individual differences in temperament

When children first meet a stranger, there is great variation in how much they will approach and engage with the stranger. While individual differences in this type of behavior—called social wariness—are well-documented in temperament research, surprisingly little attention has been paid to the social groups (such as race) of the stranger and how these characteristics might influence children's social wariness. In contrast, research on children's social bias and interracial friendships rarely examines individual differences in temperament and how temperament might influence cross-group interactions. The current study bridges the gap across these different fields of research by examining whether the racial group of an unfamiliar peer or adult moderates the association between temperament and the social wariness that children display. Utilizing a longitudinal dataset that collected multiple measurements of children's temperament and behaviors (including parent-reported shyness and social wariness toward unfamiliar adults and peers) across early childhood, we found that 2- to 7-year-old children with high parent-reported shyness showed greater social wariness toward a different-race stranger compared to a same-race stranger, whereas children with low parent-reported shyness did not. These results point to the importance of considering racial group membership in temperament research and the potential role that temperament might play in children's cross-race interactions.

Research Highlights

• Previous research on temperament has not considered how the race of strangers could influence children's social wariness.
• We find evidence that 2- to 7-year-old children with high parent-reported shyness show greater social wariness toward a different-race stranger compared to a same-race stranger.
• These results point to the importance of considering racial group membership in temperament research.
• Our findings also suggest temperament may play a role in children's cross-race interactions.

     

Taking parent personality and child temperament into account in child language development

Individual differences have become increasingly important in the study of child development and language. However, despite the important role parents play in children’s language, no work has examined how parent personality impacts language development. The current study examines the impact of parent personality as well as child temperament on language development in 460 16- to 30-month-old children and 328 31- to 42-month-old children. Findings from both groups suggest multiple aspects of children’s language abilities are correlated with their parent’s personality. Specifically, parent consciousness, openness, and agreeableness positively correlate with child vocabulary size and other language abilities. Results also replicate and expand research on child temperament and language – child effortful control and surgency were positively correlated, and negative affect negatively correlated with most language abilities even after controlling for parent personality. Critically, parent and child traits appear to impact a child’s language abilities above and beyond well-known predictors of language, such as age.     

Ethnicity Moderates the Association between Autonomic Functioning and Temperament in Preschool Children

Abstract

Respiratory sinus arrhythmia (RSA) has been extensively investigated as a marker of adaptive emotional functioning in both children and adults, with studies linking RSA to temperamental dimensions such as positive affect and extraversion. However, few studies have examined the extent to which relations between RSA and temperament characteristics vary across ethnicity in childhood. We examined relations between respiratory sinus arrhythmia (RSA) and temperament dimensions (Activity Level, Task Orientation, and Affect-Extraversion) and the moderating role of ethnicity among preschoolers. Chinese- American (n?=?28, M_age = 54.30?months) and European American (n?=?32, M_age = 50.41?months) preschoolers were assessed for their temperament and RSA. Findings indicated higher levels of Affect-Extraversion among European American children. Ethnicity moderated the association between the baseline RSA and the Affect-Extraversion dimension of temperament, with a significant positive association found only for European American children. More research is needed to examine the effects of social-cultural experiences on the relation between children’s affective regulation and autonomic functioning development.     

Sport participation,screen time,and personality trait development during childhood

This investigation explored the contribution of extracurricular sport and screen time viewing (television viewing and electronic gaming) to personality trait stability and change during childhood. Two independent samples of 3,956 young children (age 6) and 3,862 older children (age 10) were taken from the Longitudinal Study of Australian Children. Parent‐reported child sport participation, screen time, and personality traits were measured at baseline and again 24 months later. Young children who were more active recorded more of a decrease in introversion, less of a decrease in persistence, and less of an increase in reactivity, than those who were less active. Older children who were more active recorded less of an increase in introversion and more of an increase in persistence than those who were less active. In addition, young children who continued participation in extracurricular sport had greater intra‐individual stability of personality for introversion. These finding suggest that an active lifestyle might help to facilitate desirable personality trait stability and change during childhood.     

Cross-cultural differences in temperament: Comparing paternal ratings of US and Dutch infants

This study conducted longitudinal comparisons of US and Dutch paternal ratings of temperament, measured via the Infant Behaviour Questionnaire-Revised, at 4 months (US n = 99; Dutch n = 127) and 12 months (US n = 66; Dutch n = 112) of age. US fathers rated their infant higher in the broad temperament trait Surgency, and its subscales vocal reactivity, high-intensity pleasure, and activity level. US fathers also rated their infants higher in negative emotionality, and its subscales of sadness, distress to limitations, and fear. Dutch infants received higher ratings in falling reactivity. Though the cultures did not differ in ratings of Orienting/regulatory capacity, US infants were higher on the subscale duration of orienting, and lower in soothability. Significant culture-by-age and culture-by-gender interactions were also noted. Overall, results are largely consistent with those reported for Dutch mothers and speak to considerable differences in early temperament development between cultures viewed as largely similar because of their Western/individualistic orientations.
