AVOIDANCE LEARNING IN SHUTTLING AND NONSHUTTLING SITUATIONS, WITH AND WITHOUT A BARRIER
TL;DRAbstract
A 2×2 factorial experiment was run in order to obtain information regarding the effects of “shuttling” condition and those of 15-cm barrier upon avoidance learning in a modified Mowrer-Miller shuttle box. 40 male albino rats were randomly assigned to one of the four groups, Sh-0, Sh-15, nonSh-0, and nonSh-15, and they all underwent 15 daily avoidance learning sessions of 10 trials each. The results indicated that rate of acquisition was faster and overall level of avoidance performance higher in the nonshuttling condition than in shuttling condition. The level of avoidance performance was higher in nonbarrier groups than in barrier groups. An interpretation in terms of “conflict” was attempted of the fact of inferior performance of shuttling groups. Hullian notion of Ir was applied to account for the barrier effect.
