Event-related potentials (ERPs) were utilized in an investigation of 21 six-month-olds' attention to and processing of global and local properties of hierarchical patterns. Overall, infants demonstrated an advantage for processing the overall configuration (i.e., global properties) of local features of hierarchical patterns; however,…

Three experiments tested the hypothesis that the differences in infants' time of looking at a stimulus are due to infants' differential sensitivity to global and local visual information. Found that both long- and short-looking four-month-old infants were sensitive to both types of information. These results do not support the hypothesis. (MDM)

Four experiments tested four month olds on visual discrimination tasks. As the time allotted to solve these problems was shortened, infants who looked at stimuli for a short amount of time performed better than other infants, indicating that performance superiority was attributable to speed of processing.

Investigated whether individual and developmental differences in look duration were correlated with latency to disengage fixation from a visual stimulus for 3- and 4-month olds. Found that look duration was correlated with disengagement latency. Three-month olds showed slower latencies than 4-month olds. Long-looking infants showed greater…

Eight reflective and eight impulsive preschool children were tested in a forced-choice recognition memory task. Reflective children made more correct recognition choices than did impulsive children under all experimental conditions. (ST)

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)

Study investigated whether the observed individual differences in visual pursuit endure beyond the neonatal period. (Authors/MB)

Factor analysis of 25 rating scales from Bayley's infant behavior record were performed for a sample of about 300-400 infant twins tested one or more times between 3 and 24 months of age. The analyses provided five major and two minor factors that were considerably consistent at all ages. (Author/DB)
