Partial information and choice behavior in differential reward magnitude learning

Ss were first trained on a word-number paired-associate list and then given testing on a two-choice differential reward learning paradigm. One of the two words in each pair had been used in the paired-associate training, and the number of points associated with the word was the same as during paired-associate learning. The other member of each pair was new and could have either more or fewer points than the known member of the pair. Speed of learning to choose the higher valued member in these pairs was directly related to amount of reward.
