Septal lesions and reversal learning in dogs.

The course of asymmetrical or symmetrical go, no-go differentiation reversal was compared in 16 control and 16 septally lesioned dogs using two pairs of auditory stimuli (similar or dissimilar). The magnitude of impairment observed during the course of reversal in septal dogs was affected by the quality of discriminated stimuli, asymmetrical or symmetrical differentiation procedure and the extent of lesion. The results suggest that septal and normal dogs solving the reversal problem used different strategies for transformation of conditioned properties of the stimuli.
