title: Infants' discrimination of moving and stationary objects.
abstract: 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.
