A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

Investigates intersensory interaction between auditory and visual stimulation in newborn infants. Following auditory stimulation, newborns' visual preferences for light patches of different intensity were examined. Results indicate that newborns attend to quantitative variations in stimulation and that these variations reflect both the objective…

This study examined behavioral correlates of the rapid central nervous system changes occurring in the first 4 months of life. It was hypothesized that during the early months of infancy, visual preference would occur as a function of quantitative dimensions of the stimuli (size) which could be mediated at a subcortical level. It was further…

Studied feeding-related arousal effects on a visual recognition paired-comparison task at newborn, 1, and 4 months of age. Found that newborns and 1-month olds shifted from a familiarity preference before feeding to a novelty preference after feeding. Control-group testing confirmed that shift was not due to increased stimulus exposure. By 4…
