The mechanical ability of subnormal boys

Abstract

100 subnormal boys enrolled in special classes were compared with an equal number of normal boys in the 7th grade as to performance on the Minnesota Spatial Relations Test. In general the subnormal group is inferior to the normal group both in time and error scores. A brief review of the literature on this topic is included.
