With a Brief Discussion on Defect and Retardation in Mentally Handicapped Children
Published Online:https://doi.org/10.1176/ajp.95.5.1215

With a mental retardation of 5 years 9 months, a retardation in reading of 4 years 5 months and in arithmetic of 6 years 8 months, this boy has a definite defect in the finger schema.
