Attention-orienting and attention-holding effects of faces were investigated in a sample of 64 children, aged 4 to 8 months old. A visual preference task was used, in which pairs of faces and toys were presented in eight 10-second trials. Effects of age and sitting-ability were examined. Attention-orienting toward faces was measured using the…

Outlines a method by which observation time as measured by visual fixation on an object in the visual field can be predicted for N items viewed simultaneously in the field when the time for observing each item presented singly is known. (Author/MG)

Results of this study of 72 4-month-old infants suggest caution in using an overt demonstration of habituation as a necessary index of perceptual learning. (Author/MG)

Subjects of this study were 19- and 23-week-old infants. Results showed that the older infants demonstrated differential attention to novel over familiar stimuli during recognition tests. An examination of their responsiveness during familiarization presentations indicated differing trends of looking activity. (Author/CS)

Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)
