Four facial stimuli derived from the Bolton standards of craniofacial development representing a human male at 6 months, 3, 8, and 18 years of age were used in a test of Lorenz's concept of babyishness and of the discrepancy hypothesis. Subjects were 87 four-month-old infants. (Author/MP)

Visual pattern preferences were established for 96 9- and 13-week-old infants using stimuli varying in contour density presented either at a low, moderate, or high luminance level. Age differences in the maximally preferred patterns across stimuli and luminance levels indicated that luminance interacts with contour density in determining stimulus…

This report describes two exploration studies which examined the development of infants' intermodal knowledge by examining infants' auditorily guided visual search for objects. Experiment 1 examined intermodal search for the mother and father by 9 infants at each of three age levels: 3, 5, and 7 months of age; the final sample was 23 infants.…

This experiment examined developmental changes in the ability of infants to learn conceptual categories regarding the human face. A total of 108 infants, aged 18, 24, and 30 weeks, were habituated to (1) the same face in the same orientation, (2) the same face in differing orientations, or (3) different faces in different orientations. All…

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)

Results suggest that the human infant's response to visual stimulation undergoes change during the neonatal period. (Authors)

Examined the visual scanning patterns of infants ages 6, 10, and 13 weeks who viewed static geometric figures. Measures of fixation dwell-times, saccade lengths, and the choices and sequences of saccadic targets revealed that, although younger infants demonstrated salience-guided scanning behavior, older infants increasingly utilized volitional…

The purpose of this study was to cross-sectionally and longitudinally examine the developmental process of search behavior in infancy. Subjects were 23 Japanese normal infants (11 males and 12 females) who were individually tested once a month from the age of six to 13 months in laboratory settings. Small toys and three white opaque cubic boxes…

Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…
