Abstract
To examine Schneirla's biphasic hypothesis that effectively weak stimulation results in approach-type responses and effectively strong stimulation results in withdrawal-type responses, 90 dB white noise stimuli were presented to twenty-five, 2-day-old female infants. Based on prior investigation this stimulus was expected to be effectively strong when presented at the right ear and effectively weak when presented at the left ear. Results obtained from electro-oculargraphic recording of the infants’ eye movements supported this hypothesis in that significant towards-turning occurred when the stimulus was presented at the left ear and significant away-turning occurred when the stimulus was presented at the right ear.
