From a perceptual learning perspective, infants use social information (like gaze direction) in a similar way as other information in our physical environment (like object movements) to specify action possibilities. In the current study, we assumed that infants are able to learn an affordance upon observing an adult failing to act out that…

Three experiments examined infants' processing of three-dimensional (3D) information in static images. Results indicated that 3-month olds are sensitive to 3D cues in static images. However, discrepancies based on these cues may not engage infants' attention like those based on fundamental features. (Author)

Two experiments examined whether infants are sensitive to holistic combinations of line junctions in 2-D images that adults use to derive overall 3-D structure. Results suggested that 3-month-olds are sensitive to holistic combinations of line junctions that adults use to derive 3-D information but also selectively attend to these 3-D cues in…

Human neonates selectively fixated patterns with curved rather than straight contours when the outermost contours differed in this form variable and when quantitative variables were controlled. Data indicated the presence from birth of a discrimination ability basic to later form perception. (Author/ED)

The primary purpose of this study was to examine whether a general perceptual model developed by Vitz and Todd (1971), capable of dealing with multiple determinants of attending, is useful for understanding infant attending. The model, previously used in research with adults, assumes that perception can be represented as a stochastic sampling…

The eye movements of infants, between 4 and 11 weeks old, were recorded while they viewed either a representation of a face or nonface stimulus. (Author/SB)

Three experiments examined 4- to 10-month-olds' perception of audio-visual (A-V) temporal synchrony cues in the presence or absence of rhythmic pattern cues. Results established that infants of all ages could discriminate between two different audio-visual rhythmic events. Only 10-month-olds detected a desynchronization of the auditory and visual…

Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

A total of 48 8- to 14-week-old infants were presented with a non-contingently moving visual stimulus and the infants' visual attention was measured. Infants who exhibited decrements in attention to the non-contingent stimulus showed recovery in attention when the same stimulus was made to move contingent upon a motor response. Moreover, wisual…

Three experiments assessed the intersensory redundancy hypothesis in early infancy. Findings indicated that habituation to a bimodal rhythm resulted in discrimination of a novel rhythm, whereas habituation to the same rhythm presented unimodally resulted in no evidence of discrimination. Temporal synchrony between the bimodal auditory and visual…

This study examines the relationship between mother-infant behavior and the infant's performance on perceptual-cognitive tasks as a function of the infant's sex. A total of 189 12-week-old infants and their mothers were observed in their homes during 2 hours of infant awake time. In addition, the Mental Development Index (MDI) of the Bayley Scales…

Function of attention in infants is explored. Assuming (1) that infants respond differently to novel situations than to familiar ones; (2) that the infant's pattern of response is a partial reflection of the process of acquiring a perceptual memory of the stimulus, and (3) that sex differences may occur in the rate of habituation, 120 infants…

This monograph is a collection of papers describing a series of loosely related studies of visual attention, auditory stimulation, and language discrimination in young infants. Titles include: (1) Infant Attention and Discrimination: Methodological and Substantive Issues; (2) The Addition of Auditory Stimulation (Music) and an Interspersed…
