The purpose of this experiment is to test whether shift flexibility in kindergarten children is a joint function of rule-usage and inhibition of attention. Sixty-six children were given either a distraction or facilitation condition in a computerized version of the dimensional change card sort task. In the distraction condition, the background of…

Three experiments examined the hypothesis that individual differences in look-duration during infancy covary with different modes of visual intake and encoding, with longer look-durations reflecting encoding based on prolonged inspection of local visual properties, and briefer durations reflecting encoding based on a global, or global-to-local…

This study examined 4- and 6-month-olds' responses to static or dynamic stimuli using behavioral and heart-rate-defined measures of attention. Infants looked longest to dynamic stimuli with an audio track and least to a static stimulus that was mute. Overall, look duration declined with age to the different stimuli. The amount of time spent in…

Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…

Examines the potential contribution of different neural systems to developmental change in the duration of visual fixation, and the individual differences in that variable that are predictive of subsequent cognitive function. Presents hypotheses concerning two specific and independent neural systems and how they might contribute to individual and…
