This study examined the power of nonshared environment to differentiate adolescent monozygotic twin development and the extent to which this power varied across social structural contexts. Findings indicated that differences in maternal closeness, teacher bonding, and religious participation differentiated twins on emotional distress. Family…

This study examined a model of emotional, cognitive, and behavior predictors of peer acceptance in 201 early elementary school students. Findings indicated that social skills mediated the effect of emotion knowledge on same- and opposite-sex social preference.

Girls were less willing to…

This study examined cultural differences and similarities in socialization during free play and a waiting task among Japanese mothers and their preschoolers temporarily residing in the United States and U.S. mothers and their preschoolers.

Investigated the extent to which 3.5-month-old infants trained in amodal auditory-visual relations between falling objects and the sounds they made could generalize their intermodal knowledge to a new task and across events. Found that infants tested with familiar events and with events of a new color or shape showed learning and transfer…

Four studies examined 10- to 18-month-old infants' ability to detect and encode correlations among features in a motion event. Findings indicated that the youngest infants process static features in an event independently but do not process correlations among dynamic features; the oldest detect correlations between all three features when the…

Compared face recognition ability in young children with autism to that of children with typical development and developmental delay. Took electroencephalographic recordings of brain activity while children viewed pictures of their mothers and unfamiliar females, and familiar and unfamiliar toys. Found that autistic children showed no differences…

Examined associations between tympanic membrane (TM) temperature asymmetries and biobehavioral attributes of 4- to 8- year-old children. Found shared patterns of associations that linked TM temperature lateralities to individual differences in behavior and socioaffective difficulties. Found that warmer left TMs were associated with affectively…
