Described experiences of 84 German toddlers enrolled or not enrolled in child care. Found total amount of care per weekday did not differ by child-care status; child-care toddlers received lower care levels from center providers; their mothers engaged in more social interactions during nonworking hours than did mothers of home-only toddlers; and…

Examined whether and when children use information about others' mental states to invent or select persuasive strategies in three studies. Found older children, but not preschoolers, used belief information in stories to select arguments; and kindergartners' and first-graders' reasoning on false belief tasks suggested the failure to consider…

Tested the tracking/surveillance explanation of why parental knowledge is linked to adolescent adjustment. Found that across age and informant, high parental knowledge was linked to good adjustment in Swedish 14-year-olds, but children's spontaneous information disclosure explained more of these relations than parents' knowledge. Suggested that…

Examined parent-child play with sex-stereotyped toys in young U.S. children of varied ethnic background. Found that the play activity accounted for a large proportion of the variance in parents' and children's mean affiliation and assertion ratings. Identified gender and ethnic group differences. Highlighted the importance of role modeling and…

Examined 2-, 2.5-, and 3-year-olds' reasoning while searching for a ball that had been rolled behind an occluder. Found only 3-year-olds were able to reliably select the correct door; all children could retrieve a toy hidden in the same apparatus if it was hidden from the front by opening a door; and younger children used a variety of strategies.…

Examined the relation between mothers' perception of their capacity for controlling infant crying and a later measure of compliance with parent requests by toddlers. Found that toddlers of mothers in the low and high illusion of control (overestimating of maternal control) groups were more likely to be highly defiant than were toddlers of mothers…

Interviewed mothers to examine the developmental significance of preschoolers' imaginary companions. Found that relationships with invisible companions were described as sociable and friendly, whereas personified objects were usually nurtured. Object personification frequently occurred as a result of acquiring a toy; invisible friends were viewed…

Data from Colorado Adoption Project were used to examine hypothesis that association between parental divorce and children's adjustment is mediated by genetic factors. Findings for psychopathology were consistent with an environmentally mediated explanation for the association. Findings for achievement and social adjustment were consistent with a…

Assessed preschoolers' peer aggression and emotional displays outside of and during aggressive interactions, their emotion knowledge, and peer acceptance. Found that connections between affective dispositions and aggression and peer acceptance varied as a function of the emotion context and the particular emotion involved. Significant connections…

Three experiments assessed the claim that preschoolers override form class cues in the interest of honoring word- meaning assumptions when acquiring new labels. Results demonstrated that children respected the form class cues when these cues and word-meaning assumptions suggested conflicting interpretations. It was suggested that past findings…

Examined risk mechanisms and protective factors in the relation between aggression in childhood and long-term adult unemployment among participants in the Jyvaskyla Longitudinal Study of Personality and Social Development. Found that aggression at 8 years predicted school maladjustment at age 14, which was related to unemployment. Child-centered…

Two experiments involving two sets of actions using two stimuli sets examined deferred imitation to trace changes in memory retrieval by 18- to 30-month-olds. Results indicated that target action recall with different stimuli increased as a function of age, particularly after a delay. A unique verbal label facilitated 24-month-olds' performance…

Examined the constructs of connectedness and autonomy in relation to 5-year-olds' relational competence, including socioemotional orientation, friendship, and peer acceptance. Found that connectedness was correlated with children's socioemotional orientations, number of mutual friendships, and peer acceptance, and that the relation between…

Three experiments investigated use of visual input and body movement input arising from movement through the world on spatial orientation. Experiments involved infants searching for a toy hidden in one of two containers. Findings indicated that search was best after infant movement in a lit environment prior to searching; all other conditions led…

Two experiments investigated factors affecting joint visual attention in 12- and 18-month-olds. Findings indicated that parental pointing at objects elicited more episodes of joint visual attention than looking alone. Although infants most reliably followed gestures to targets in front of them, even 12-month-olds followed gestures to targets…
