Learning in the intact cockroach (Periplaneta americana) when placed in a punishment situation.

Examined whether 40 intact cockroaches, Periplaneta americana, in a yoked-control punishment paradigm exhibit escape or avoidance learning, or both. Evidence for avoidance learning was unequivocal. Escape learning was not found. Asymptotic avoidance learning was found by 1.5 min. of training. The advantages of defining learning by experimental-control differences developing during training are discussed. (15 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
