Proreal syndrome in dogs.
Proreal lesions were made in dogs trained on different forms of delayed alternation (involving either a single or two tones), spatial reversal, and go left-go right task. Proreal animals were impaired on a variety of delayed alternation tasks. On the basis of two additional spatial tests (with and without delay) involving double choice to auditory stimuli presented in spatial contiguity or discontiguity with responses, it is concluded that CS-R spatial contiguity test is solved by localization of foodwells whereas the discontiguity test is learnt on the basis of kinesthetic cues involved in head turnings. Proreal lesions impair only the tests based on localization, whereas learning based on discrimination of kinesthetic cues is, on the contrary, improved. The results suggest that impairment of delayed response tests is due to the overwhelming role of responses based on kinesthetic cues which interfere with correct performance based on localization of foodwells.
