Individuals track probabilities, such as associations between events in their environments, but less is known about the degree to which experience--within a learning session and over development--influences people's use of incoming probabilistic information to guide behavior in real time. In two experiments, children (4-11 years) and adults…

Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school-age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy-three 7- to 12-year-olds using an effort…

The authors examined internalizing behavior problems at middle childhood, adolescence, and young adulthood and brain-based measures of stress vulnerability in 154 right-handed, nonimpaired young adults (M age = 23 years): 71 (30 males, 41 females) born at extremely low birth weight (ELBW; less than 1,000 g) and 83 (35 males, 48 females) controls…

Do children have coexisting but contradictory beliefs about things like magic? Some patterns of behavior that seem to reflect contradictory beliefs may stem from children's recognition that their knowledge about events is incomplete and therefore things may occur without them understanding how. In addition, children may hold certain beliefs that…

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…

Results indicating that adult males direct more praise, verbal help, and other forms of positive attention to responsive than to unresponsive children are contrasted with results obtained in a previous study of the reactions of women subjects. (Author/JMB)

This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and…

Examines relations between Matthews Youth Test for Health ratings on hyperactive boys and diverse measures obtained from five sources: direct behavior observations; staff evaluations, nonparticipant observer ratings, peer nominations, and self-reports. (HOD)

Examined patterns of mothers' and fathers' differential treatment of first-born and second-born school-age siblings in 110 families and the links between parents' differential treatment and children's well-being and dyadic family relationships. Found that parental patterns were linked to differences between the siblings' well-being and that…

Contrasts a fixed-rate presentation list with one in which half the items in a single list were presented at a fast rate and half at a slow rate during paired associative learning with 24 children (aged 8 to 22 years) who were diagnosed with having an attention deficit disorder. (HOD)

Decribes age trends in television viewing time and visual attention of children and adults videotaped in their homes for 10-day periods. Shows that the increase in visual attention to television during the preschool years is consistent with the theory that television program comprehensibility is a major determinant of attention in young children.…

Examines the hypothesis that biases in peer interpretations of social behavior may contribute to the stability of social acceptance and rejection in children. (HOD)

Examined whether children who vary in their behavioral responses to ambiguous provocation but have similar attributional processes differ in their social goals and self- efficacy perceptions. Subjects were 781 4th and 5th graders. Found that aggressive, withdrawn, and problem-solving responders differed in the social goals and self-efficacy…

This study examined children's recognition memory for descriptions of maladjusted behaviors displayed by hypothetical peers. Children were also asked about the desirability of these hypothetical peers as friends. (PCB)

Observed the decision-reaching and leadership behavior of children in same- amd mixed-age triads by coding their verbalizations in arriving at a consensus for their preference ranking of eight pictures. (HOD)
