Differential Dishabituation as a Function of Magnitude of Stimulus Discrepancy and Sex of the Newborn Infant.
Friedman, Steven; And Others
This study uses a habituation paradigm to systematically investigate the discrepancy hypothesis with male and female new borns. In addition, multiple visual response measures are used in monitoring the habituation process and the infant's response to various degrees of novelty. Ss were 36 apparently normal newborns (half of each sex) ranging in age from 28 to 82 hours. A target was placed against the inside of the infant's crib, and two observers stood behind it, facing the infant. Total looking time and number of looks were recorded. Non-glossy, black and white checkerboard targets in three sizes were used as visual stimuli. Each trial consisted of a 60-second exposure, and presentations continued until evidence of response decrement in looking time occurred. Each infant received one 60-second trial 5-10 seconds after the last decrement criterion trial. The hypothesis that infants are capable of demonstrating habituation to visual stimuli was supported. The findings also demonstrate that the visual response of female newborns is compatible with the discrepancy hypothesis. The response of females in this study is consistent with reports of sex differences indicating that the female newborn is generally more responsive and receptive to sensory stimulation than is the male. It is clear that effects attributable to sex cannot be explained effectively without reference to the context of stimulation. [Filmed from best available copy.] (KM)
