Persistence of the effects of choice on paired-associate learning.

Four experiments are reported in which half of the subjects were permitted to choose either the stimulus or response members of S-R pairs from groupings of alternative stimuli or responses following the procedures of Perlmuter, Monty, and Kimble. The other subjects were exposed to the materials and were forced to learn the material chosen by their yoked partners. Approximately 24 h later, both groups learned PA lists comprised of either the chosen or forced material. Choosing either the stimulus or the response facilitated performance irrespective of whether the other member of the S-R pair was present at the time of choosing. This finding ruled out an associative hookup interpretation in favor of a purely motivational hypothesis and demonstrated the temporal durability of the effect of choosing.
