Performance on tasks of memory and of attention was consistently interrelated for nonlearning disabled children and less consistently so for learning disabled subjects. Hyperactivity was also related to poorer performance on the cognitive measures. (Author/DB)

Examined the effect of heart rate and behavioral measures of attention on infants' distractibility. Found longer distraction latencies during attentional engagement as defined by heart rate changes or behavior than for inattentive periods. Infants had longest distraction latencies when heart rate and behavior measures both indicated engagement.…

The mental capacity of 120 children aged 10 to 16 years was measured with 2 visual information-processing tasks, and their level of moral development was assessed with the Sociomoral Reflection Measure. Results suggest that mental capacity is a necessary but not sufficient condition for moral developmental growth. (LB)

A study of 31 typical children aged 5-10 engaged in child-to-child social interactions, found joint attention was positively related to age and activity, eye gaze was low relative to joint attention and object engagement, and eye gaze was significantly less than what has been reported for adult-child and adult-adult dyads. (Contains references.)…

A new revision was developed using Rasch psychometric techniques to build a Knox's Cube Test (KCT) variable and item bank using the tapping series from all previous editions. The report forms developed give a clear picture of the subject's performance set in a context that is both normative and criterion. (Author/BW)

Robust interference effects were found which declined with age. Manipulating discriminability of the relevant stimulus dimension resulted in large changes in sorting time, but interference effects did not vary with baseline difficulty. These results were interpreted as strongly supporting both an absolute decrement model and a developmental trend…

Three experiments examined infants' perceptions of their own leg movements as presented to them via online video that varied the spatial orientation and directionality of movement. The infants looked significantly longer and generated significantly more leg activity while looking at the view displaying a left-right inversion than while looking at…

Significant, though moderate, correlations between some of the verbal creativity measures and the selective attention variables were found, though this relationship changed as a function of age and the type of creativity measured. (DLS)

Examined visual fixation in infants 6 months to 2 years old for fit with theory of attentional inertia. Found that fixations had lognormal distribution, heart rate decreased during a look, and heart rate returned to prestimulus levels immediately before look offset. Older children showed different looking patterns to two types of stimuli; younger…

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.…

Reviews findings of recent television research and discusses two dominant issues: the nature and determinants of children's attention to television, and the amount and kind of content retained by different age groups. It is recommended that research on media effects incorporate age-related and individual difference factors. Nineteen references are…

This final report discusses research and literature analyses concerned with the attentional mechanisms in children's learning and analysis of cognitive changes from ages 5 to 7. The long-term objective of the project was to relate knowledge about children's attention and learning to issues of educational practice. The project focused its efforts…

Background: Using longitudinal data from the NICHD Study of Early Child Care and Youth Development, we examined behavior problems and social and academic outcomes from ages 9 through 12 in children classified into five trajectories of physical aggression, on the basis of maternal ratings obtained from 24 months through 9 years (N = 1195). Methods:…

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…
