In executing purposeful actions, adults select sufficient and necessary limbs. But infants often move goal-irrelevant limbs, suggesting a developmental process of motor specialization. Two experiments with 9- and 12-month-olds revealed gradual decreases in extraneous movements in non-acting limbs during unimanual actions. In Experiment 1,…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

This paper reports on the development and use of several tools designed to sensitize caregivers to the fact that infants are very different from one another and that caregiving needs to be tailored to the styles and needs of each child. Four approaches were used: (1) having caregivers rate the infants regularly on a small number of rating scales…
