Series of experiments indicates that young infants are more sensitive to the spatial orientation of forms than was previously thought. This report is based on a dissertation submitted to the University of Strathclyde, August, 1969, in partial fulfillment of the requirements for the degree of MSc. (MH)

Infants of 6 months and older can be said to have discriminated between different orientations of the same form. (Author)

Results indicate that for children in this study's age range orientation is a less salient discriminative cue than either size or color. (Author/MB)

Tries to unravel some of the problems concerning the previous finding that increasing the number of depth cues in pictures has a depressing effect on spatial accuracy of three dimensional reconstruction of pictures. Evidence does not support a deficiency in perceiving pictorial depth in African children. (AM)
