Infant visual attention under response-contingent and response-independent conditions

Abstract

The visual attention behavior of 2- to 3-month-old infants was monitored as part of their participation in an operant conditioning study. Attention was monitored under three conditions: a baseline condition where a visual target remained stationary; a baseline conditioning where the target was made to move on an aperiodic, response-independent schedule; and a conditioning phase where the target was operantly under the control of the subjects. Fixation time differed significantly as a function of experimental condition, with the response-contingent condition producing the greatest amount of fixation and the stabile, baseline condition producing the least amount of fixation. The implications of the findings for intervention purposes are discussed.
