Eye-trackers suitable for use with infants are now marketed by several commercial vendors. As eye-trackers become more prevalent in infancy research, there is the potential for users to be unaware of dangers lurking "under the hood" if they assume the eye-tracker introduces no errors in measuring infants' gaze. Moreover, the influx of voluminous…

In 2004, McMurray and Aslin edited for "Infancy" a special section on eye tracking. The articles in that special issue revealed the enormous promise of automatic eye tracking with young infants and demonstrated that eye-tracking procedures can provide significant insight into the emergence of cognitive, social, and emotional processing in infancy.…

Yoshida and Smith (this issue) provide one of the first attempts to overcome the most serious impediment to the use of head-mounted eye trackers with infants: Except in rare cases they are not light enough to be worn on an infant's head, or the infant does not tolerate looking through a half-silvered mirror that is hanging on a rigid stalk…

The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

Examines the nature of mother-child bonding from the prenatal stage through early infancy, discussing how the mother's actions, even before birth, stimulate her child's senses. Explains the crucial role that physical contact, breastfeeding, and visual stimuli have on mother-child bonding in human and animal newborns. (MDM)

Examines evidence that the research community studying infants' object concept and the community concerned with adult object-based attention have been studying the same natural kind. Maintains that the discovery that the object representations of young infants are the same as the object files of mid-level visual cognition has implications for both…

Summarizes findings on infants' capacity for object segregation. Maintains that infants can use featural and experiential information for segregation and individuation purposes long before 12 months of age. Disputes the claim that formation of object categories awaits early word learning, but acknowledges that language may play a key role in…

Theoretical implications of individual differences among infants in responsiveness to visual novelty being predictive of later intelligence differences are discussed. Issues discussed include: continuity of intelligence over development, relation of aspects of information processing to intelligence, role of hereditary and environmental influences…

Responds to Needham and Baillargeon's criticisms and offers an alternative resolution of the conflicting results between the laboratories regarding abilities of infants less than 12 months to use property/featural information for object individuation. Maintains that kind concepts are acquired as infants approach their first birthday and that…
