This study addressed three major questions pertaining to habituation of visual attention in infants: (1) does habituation occur gradually? (2) how do fast and slow habituators compare in their response to discrepancy? and (3) does intervening stimulation produce interference with infants' visual recognition memory? The subjects were 36 17-week-old infants, half were male and half female. Each infant sat on his or her mother's lap facing a semi-circular screen while an observer watched the infant's head and eye movements on a television monitor located in an adjacent room. Each trial consisted of the infant's looking at a blinking light on the left, followed by one unlimited fixation of the stimulus on the right. Each infant saw the same pattern repeatedly until his or her fixation time reached the specified habituation criterion. Each infant was then presented with a pattern discrepant from the standard stimulus. The findings indicated that infants do not gradually decrease their response to a repeated stimulus, but rather seem to habituate within one or two trials. Further, there were distinct, non-overlapping distributions of trials to criterion for the fast and slow habituators with both groups of infants showing the same degree of recovery to a novel stimulus. Finally, evidence of interference with infants' recognition memory was found and attributed to there being only a single, repeated intervening stimulus. (JMB)
