  • Title: Effects of task-irrelevant cues and reinforcement delay on choice-escape learning following inescapable shock: evidence for a deficit in selective attention.
    Author: Minor TR, Jackson RL, Maier SF.
    Journal: J Exp Psychol Anim Behav Process; 1984 Oct; 10(4):543-56. PubMed ID: 6491612.
    Abstract:
    Prior exposure to inescapable shock has been reported to interfere with choice-escape learning, but several investigators have failed to obtain this effect. A series of five experiments examined the conditions under which choice-escape learning in an automated Y-maze is impaired by pretreatment with inescapable shock. Inescapably shocked rats made more errors and responded more slowly than did controls only when shock termination was delayed and task-irrelevant cues were present during choice-escape training. These findings are discussed in terms of information processing and neurochemical consequences of exposure to inescapable shock.
