Rapid assessment of stereopsis in pre-verbal children using operant techniques: a preliminary study.
A new operant conditioning program, based upon principles of errorless discrimination learning, was used to assess stereopsis in 24-35 months old children. Results indicated that this program was more successful in generating responding to stereograms than standard contour or random dot tests of stereopsis. It was concluded that the most effective procedure for evaluating subjective visual findings in pre-verbal patients is one that recognizes the importance of programmed discrimination learning and operant motivational techniques.
