Groups of autistic and mentally retarded children were compared for the degree of stimulus overselectivity manifested during test probes after discrimination learning. Results demonstrated that stimulus overselectivity was a function of diagnostic category when groups were equated for performance IQ and mental age. Procedures used to obtain IQ as well as discrimination learning rate were also shown to be equivalent. Pulse rate response suggested that the test probes may be assessing performance during the early trials of a transfer problem for both groups of children. Implications for 'one-look' models of discrimination learning were discussed.
