We often need to infer unknown properties of objects from observable ones, just like detectives must infer guilt from observable clues and behavior. But how do inferential processes change with age? We examined young and older adults' reliance on rule-based and similarity-based processes in an inference task that can be considered either a…

Under what conditions will people generalize and remember observed social information? Preschool- (n = 44) and young school-age (n = 46) children and adults (n = 40) heard short vignettes describing characters' actions and motives on a single occasion. Characters were introduced using either proper names or category labels. Test questions asked…

The stability of language across childhood is traditionally assessed by exploring longitudinal relations between individual language measures. However, language encompasses many domains and varies with different sources (child speech, parental report, experimenter assessment). This study evaluated individual variation in multiple age-appropriate…

Recent perspectives on social dominance in normative populations have suggested a developmental progression from using primarily coercive strategies to incorporation of more socially competent strategies to attain material and social resources. Parental influences on the resource control strategies children use have been proposed but not…

The present study examined the role of attentional demand on infants' perseverative behavior in a noncommunicative looking version of an A-not-B task. The research aimed at clarifying age-related improvements in the attention process that presumably underlies the development of cognitive control. In a between-subjects design, forty 10-month-olds…

This study investigated the normative use and developmental course of physical aggression (PA), defined as use of physical force such as hitting, biting, and kicking, from 8 to 26 months and predictors thereof. We used data from the Behavior Outlook Norwegian Developmental Study, comprising 1,159 children (559 girls and 600 boys). Both mothers and…

During the transition to adolescence, several developmental trends converge to increase the importance of peer relationships, the likelihood of peer-related stressors, and the experience of depressive symptoms. Simultaneously, there are significant changes in parent-child relationships. The current study sought to evaluate whether positive…

This study drew on prospective, longitudinal data to test the hypothesis that the intergenerational transmission of positive parenting is mediated by competence in subsequent relationships with peers and romantic partners. Interview-based ratings of supportive parenting were completed with a sample of 113 individuals (46% male) followed from birth…

In this longitudinal study, we tested whether the association between oppositional defiance to parental authority (i.e., adolescents' tendency to bluntly reject parental rules) and autonomy would depend upon the specific conceptualization of autonomy. Whereas oppositional defiance would yield more interpersonal distance from parents, because…

Musical melodies are recognized on the basis of pitch and temporal relations between consecutive tones. Although some previous evidence (e.g., Saffran & Griepentrog, 2001) points to an absolute-to-relative developmental shift in listeners' perception of pitch, other evidence (e.g., Plantinga & Trainor, 2005; Schellenberg & Trehub,…

When do children develop the ability to imagine their future lives in terms of a coherent prospective life story? We investigated whether this ability develops in parallel with the ability to construct a life story for the past and narratives about single autobiographical events in the past and future. Four groups of school children aged 9 to 15…

The aim of this study was to investigate the prospective relations between parental psychosocial functioning and toddlers' sleep consolidation. Investigators met with 85 families 3 times, when children were 15 months (Time 1 [T1]), 18 months (T2), and 2 years of age (T3). Mothers and fathers completed questionnaires pertaining to their parenting…

Perceived control is an important variable for various demands involved in successful aging. However, perceived control is not set in stone but rather changes throughout the life course. The aim of this study was to identify cross-sectional age differences and longitudinal mean-level changes as well as rank-order changes in perceived control with…

The intergenerational transmission of school adjustment was explored in a sample of 213 children and their fathers. The fathers were participants in a longitudinal study that began when they were in the 4th grade, and their children have been assessed at the ages of 21 months and 3, 5, and 7 years. Two components of school adjustment were…

The present study examined adult age and sex differences in self-reported aspirations and personal meaning. Young, midlife, and older adults (N = 2,557) from the United Kingdom or United States completed an online survey of their aspiration striving, aspiration importance, and personal meaning (subscales of Purposeful Life, Exciting Life,…
