Abstract
Conducted 3 experiments with male wistar rats (n = 176) on the effects of methamphetamine and shock duration. Ss received 10 signaled shock presentations of 0-, .3-, .5-, 2-, or 6-sec duration following injections of either methamphetamine or saline. The facilitative effects of prior shock exposure (pse) on subsequent 1-way avoidance learning were augmented by methamphetamine injection in the 2- and 6-sec shock groups. Movement during pse and subsequent avoidance performance were highly correlated. While pse facilitated subsequent passive-avoidance learning, methamphetamine administered during either pse or passive-avoidance testing reduced the facilitative effects. Results indicate that response-repertoire changes during pse influence subsequent 1-way and passive-avoidance performance. (24 ref.)
