An assessment of chronic schizophrenics suggested that some showed marked perceptual‐motor disturbances and others did not. Two extreme groups of twelve each were taken from those assessed and investigated experimentally in a series of every‐day perceptual‐motor tasks. Performance was analysed in terms of nineteen basic disorders which are listed. The two groups differed strongly in the extent to which they manifested these and the difference was stable over a short period. The contrast is unrelated to general neuropsychiatric status, social variables and differential aptitudes. The resemblance of the disorders to perceptual‐motor disorders produced by certain drugs and by anoxia is noted and it is suggested that the basis of the contrast is biochemical and related to the fundamental aetiology of the schizophrenic illnesses.
