Discuss the visual preferences of neonates.
What will be an ideal response?
Answers will vary. Neonates look at stripes longer than at blobs. This finding has been used in much of the research on visual acuity. Classic research found that by the age of 8 to 12 weeks, most infants also show distinct preferences for curved lines over straight ones (Fantz et al., 1975). A study of 34 neonates found that the longer fixations on facelike stimuli resulted from a larger number of brief fixations (looks) rather than from a few prolonged fixations (Cassia et al., 2001). The infants' gaze, then, was sort of bouncing around from feature to feature rather than "staring" at the face in general.
