Object perception and motion in infants.

Male and female infants 10 weeks of age (N = 24) were presented with two distinctively patterned objects in either moving or stationary form. Measures of visual regard indicated the infants were able to discriminate between the objects whether the objects were stationary or in motion. The results are contrasted to T. G. R. Bower's assessment of infants' utilization of features in perceiving moving objects. The results are also compared to those of an earlier study which employed an operant rather than a preference technique to investigate this same problem.

Infants' discrimination of moving and stationary objects.

An operant technique was used to train 10-wk.-old infants on a simultaneous discrimination task with a checkerboard cube and a bull's-eye sphere presented in a stationary form. Discrimination testing with the objects in motion and with the objects stationary indicated that infants are able to discriminate between simultaneously presented objects whether stationary or in motion. The results are contrasted to T. G. R. Bower's assessment of infants' utilization of features in perceiving moving objects.
