Presented paired-comparison familiarization-novelty recognition task to 4-month-olds. Found that peak look duration during pretest and familiarization periods predicted recognition performance. Recognition was unaffected by choice-trial length. Longer gaze durations during pretest and familiarization were associated with more time in heart…

The relations among early cumulative medical risk, cumulative environmental risk, attentional control, and brain activation were assessed in 15-16-year-old adolescents who were born preterm. Functional magnetic resonance imaging found frontal, temporal, and parietal cortex activation during an attention task with greater activation of the left…

Issues include consistent individual differences in children's strategy choices, interpretation of differences within a framework, and the relation of differences to standardized test performance. (RJC)

To test hypotheses concerning interactional histories associated with variation in quality of infant-mother attachment, data were gathered during naturalistic home observations of 60 infants 1, 3, and 9 months of age. Responses were elicited on the Ainsworth and Wittig strange situations. Results concerned mothers' relatively greater influence in…

Data from an early intervention program for children at risk for developmental retardation were used to investigate two kinds of intellectual plasticity: developmental functions and individual differences. Possible convergences between the two realms of development are examined. (Author/RH)

Reflective and impulsive children were instructed to hasten or delay their responses on a test of hypothesis-seeking and constraint seeking conceptual strategies. Latency of response data on pretesting, training, and immediate posttests showed that the attempts to hasten or delay responses were successful in changing response latencies. (ST)

It was concluded that in grade school children the tendency to be reflective in problem solving also entails a disposition to take longer in making decisions. (Author)

Data provide evidence for the situational invariance of individual differences, and for the greater importance of capacity than of motivational variables in accounting for such differences. (Authors)

Purpose of this study was to test the adequacy of the serial habituation hypothesis as an account of the infant's perceptual commerce with visual stimuli. (Author)

Describes the development of a parent-report to assess infant temperament and presents longitudinal findings. Scales were developed to measure activity level, soothability, fear, distress to limitations, smiling/laughter, and duration of orienting. Longitudinal analyses showed that stability in some scales was age-related. (Author/DB)

Investigates the exploratory behavior of young children as it relates to individual differences in curiosity, the novelty of the objects explored, and the interactive style employed by an adult experimenter. (Author/MP)

Used growth curve analysis to describe the development of 186 preschoolers with vision impairments. Found that mental retardation and developmental delay were associated with lower developmental ages and slower growth rates. Visual function of 20/800 or worse was associated with lower developmental ages and slower growth rates in personal-social…

Examined early development of guilt in 106 children observed in laboratory paradigms in which they were led to believe they had damaged valuable objects during 2 sessions at 22, 33, and 45 months. Found support for a mediational model in which fearful temperament contributed to guilt proneness, which served to inhibit children's tendency to…

Results indicate that children who witness teachers' appraisal actions interpret some of them differently at different ages. Participants were 136 first through sixth graders who were assessed on measures of perceptions of target children and perceptions of teacher's opinions of target children. (RH)
