The subjects have typically been normal infants ages 4 to 6 months. For testing, the…

Three related experiments were conducted to investigate the effects of novel and familiar stimuli on infant attention. The procedure in each of the experiments was to place an infant before a matrix panel composed of six rows of six lights. Two patterns of lights were used to obtain the infants' fixation time: (1) a point pattern, a single…

The research was based on Eysenck's hypothesis that conditionability i s a unitary factor related to introversion-extroversion and attention span. The objective of the investigators was to devise a battery of conditioning tasks…
