Selective sustained attention is vital for higher order cognition. Although endogenous and exogenous factors influence selective sustained attention, assessment of the degree to which these factors influence performance and learning is often challenging. We report findings from the Track-It task, a paradigm that aims to assess the contribution of…

Studies of the infant's distribution of attention to stimuli of varying complexity, and of his differential attention to familiar versus novel stimuli (discrepancy), have attempted to shed light on the development of cognitive structures in the non-verbal infant. The subjects have typically been normal infants ages 4 to 6 months. For testing, the…

Presents a proposed unifying relationship between instructional methods and cognitive operations, and argues that it is the location of the processing of the learning task that defines the function, type, and extent of the instructional method required. More than 50 references are listed. (MER)

A child whose behavior reflects only perception of a stimulus and reaction to it is considered more perceptually bound than an adult whose behavior is also directed by theories, values, and ideas. Based on this analysis three testable hypotheses emrege: (1) stimulus complexity is a better predictor of attention for the more perceptually bound, (2)…

This illustrated booklet describes research procedures in the Infant Laboratory of the Educational Testing Service to investigate measurable factors in infant behavior which can predict intellectual potential. The research is currently focusing on attending, the manner in which infants respond to various stimuli presented to them during their…
