The effects of a positive reinforcement procedure in a junior high physical education class of Mentally Retarded boys was studied. One class of sixteen students was used. The class was divided into two groups, a control group, which received only usual reinforcement such as grades and praise, and an experimental group, which received free time as reinforcement for achievement on skills tests. The scores revealed that no significant difference occurred between the groups.

Recommendations include reinforcement within the physical education class instead of at a later time in the day.
