Abstract
It is the purpose of this study to determine the reaction to frustration of a group of mentally retarded children, as measured by the Rosenzweig Picture Frustration Study. Following are two hypothesis which the writer poses in regards to the reaction to frustration of mentally retarded children. Hypothesis I: Mentally retarded children will react to frustration in a significantly more extropunitive, ego-defensive manner than a normal population of comparable age and socio-economic background, as measured by the Rosenzweig Picture Frustration Study. The null hypothesis to be tested is that mentally retarded children will not differ significantly from a comparable normal population, on a dimension of Extropunitiveness as measured by the P.F. Study. Hypothesis II: The mentally retarded children's reaction to frustration will not only be significantly more extropunitive, ego-defensive than a normal group; but the M.R. group's extropunitive reaction to frustration will increase with age of the subject rather than decrease, as measured by the P.F. Study. The null hypothesis to be tested is that mentally retarded children will not increase in their amount of extropunitive reaction to frustration with age, but will be comparable to a normal group in reactions.
