Reduction of stimulus overselectivity with nonverbal differential observing responses . Three individuals with mental retardation exhibited stimulus overselectivity in a delayed matching-to-sample task in which two sample stimuli were displayed on each trial . Intermediate accuracy scores indicated that participants could match one of the samples but not both of them . Accuracy in a baseline condition was compared to accuracy with a differential observing response procedure . This procedure prompted participants to make simultaneous identity-matching responses that required observation and discrimination of both sample stimuli . These observing responses were never followed by differential consequences . When observing responses were prompted , participants ' accuracy scores improved . In a return to the baseline condition , when differential observing responses were no longer prompted , accuracy returned to intermediate levels . The results show that stimulus overselectivity can be greatly reduced by a behavioral intervention that controls observing behavior and verifies discrimination , but that exposure to such procedures alone may be insufficient for lasting benefits .
