The use of recall measures conditionalized on other performance introduces the possibility of bias due to item and/or subject selection. Several possible cases are considered. (Editor)

The general purpose of this experiment was to determine whether differences in stimulus discrimination, as determined by the MIR (missing-item recognition) test, are correlated with interference in recall, as demanded by the discriminative coding hypothesis. (Author/RK)

When subjects learned paired associates that, on the study trials, consisted of a stimulus (cue) and its correct (target) response plus two other (distractor) responses from within the list, the presence of the distractor items interfered with learning, especially when overtly pronounced as opposed to silently studied.

This experiment demonstrated that people can utilize relative situational frequency of occurrence to differentiate similary categorizable target items in paired-associate learning. (Editor)

Nelson, Brooks, and Wheeler (1975) found that interference effects produced by physical similarity among word stimuli in paired associates result from the disruption of contact with the functional stimulus and that interference with associative retrieval is minimal. Data in this research challenge their conclusion on several grounds. (Author/RK)

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)
