Two experiments on how symmetrical difficulty factors (word familiarity and concreteness) affect stages of associative learning are reported. Learning parameters reacted in a qualitatively similar manner to stimulus and response manipulations. Paired associate items are represented in memory as unitary traces rather than as separate stimulus and…

Research has indicated that interference produced by the sharing of sensory features of paired-associate stimulus words was not eliminated by processing the pairs at the meaning level. These experiments were intended to extend the range of conditions under which the sensory interference effect might persist, and to incorporate the findings within…

It was hypothesized that freedom to choose words to be learned, but not the actual choice of words per se, improves performance in paired-associate tasks. Subjects offered an attractive or meaningful choice performed significantly better than subjects offered an unattractive choice, which was equivalent to no choice at all. (Author/CP)

Five experiments were conducted comparing performance on paired-associate lists of stimuli that rhymed with lists of stimuli that did not rhyme. Results are discussed in terms of the role of input position cues in aiding discrimination among items. (Editor/RK)
