Individual differences in object-examining duration: do they reflect the use of different encoding strategies?

Much evidence has shown that individual differences in the duration of visual fixation in infancy are related to processing of wholistic versus featural properties of the stimuli. In the present study, an object-examining technique was used with 8-month-old infants to test the hypothesis that infants who display differential attention durations to visuo-manually presented stimuli will vary in their processing of wholistic versus featural aspects of the stimuli. The results confirmed the hypothesis, indicating that, after being familiarized with an object comprised of both global and local properties, long examiners attended more to an object comprised of new-local rather than new-global aspects, whereas short examiners attended more to the new-global rather than the new-local object. These findings provide support to the contention of the existence of close similarities between visual fixation and object-examining measures as indexes of infant information processing, extending the convergences between the two measures to the domain of individual differences.
