The effect of deprivation level during noncontingent pairings and instrumental learning on subsequent instrumental performance

摘要: Abstract In Experiment 1, rats received either response-noncontingent pairings of a tone stimulus with food or response-contingent instrumental training during which only responses in the presence were reinforced. During this maintained at 70 90% their growth-adjusted predeprivation body weights. subsequent test phase, one-half subjects each condition tested under weight. Subjects had 70% weight responded significantly faster to presentations than did weight-trained subjects, regardless deprivation condition. There was no effect level pairings. 2, noncontingent tone-reward nonpairings later phase weight, responding for Deprivation again produced effect. These results support two conclusions. First, expectancy learning process appears be relatively independent conditions when such takes place; and secondly, affect strength S-R associative bonds formed.
