| Abstract: | In 2 experiments with 57 male albino rats, an appetitive preconditioning procedure produced superior performance on a discriminated bar-press avoidance task. The technique was designed to minimize the number of shocks received early in training and consisted primarily of rewarding Ss with food pellets for an avoidance response in addition to terminating the warning stimulus. Ss so preconditioned were found to achieve sustained, high levels of avoidance. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
