Since the mid-1800s, experimental psychologists have been using eye movements and gaze direction to make inferences about perception and cognition in adults (Muller, 1826, cited in Boring, 1942). In the past 175 years, these oculomotor measures have been refined (see Kowler, 1990) and used to address similar questions in infants (see Aslin, 1985,…

This research unites traditionally disparate developmental domains--cognition and locomotion--to examine the classic cognitive issue of the development of inhibition in infancy. In 2 locomotor A-not-B tasks, 13-month-old walking infants inhibited a prepotent response under low task demands (walking on flat ground), but perseverated under increased…

Computational models of infant categorization often fail to elaborate the transitional mechanisms that allow infants to achieve adult performance. In this article, we apply a successful connectionist model of adult category learning to developmental data. The Supervised and Unsupervised Stratified Adaptive Incremental Network (SUSTAIN) model is…
