Abstract
An experiment was conducted to evaluate effects of prior avoidance training under varying degrees of spreading cortical depression (SD) on the subsequent performance of the nondepressed rat. All Ss met a criterion of 9 avoidance responses out of 10 trials during each of 3 experimental sessions. Conclusions are: (a) training without depression is superior to training with unilateral SD, which is superior to training with bilateral SD in facilitating subsequent performance with nondepressed Ss; (b) training with SD limited to one hemisphere is equally as effective as the same amount of training with SD alternated between the hemispheres in facilitating later nondepressed performance; (c) Ss receiving bilateral SD are incapable of avoidance learning but do improve in escape performance; and (d) there is negative transfer between extensive escape training received during bilateral SD and subsequent avoidance learning without SD.
