Spaced presentations of 12- and 15-word lists were better recalled when no task or an easy task intervened between presentations. Results indicate a lack of generality in Bjork and Allen's 1970 findings and a need for a two-factor theory of the spacing effect, and are evidence for a spacing effect. (CHK)

Subjects studied and were tested for recognition and recall of target words on lists of cue-target word pairs. List-cued recall was higher than non-cued recall, suggesting that recognition failure is independent of subjects' familiarity with task requirements. This contradicts attribution of encoding specificity phenomena to subjects' confusion.…

In two experiments using the Brown-Peterson memory paradigm, instructions to guess had small effects on recall, but sizeable effects on incidence of prior list intrustion. However, results indicate that proactive interference is primarily the result of inability to generate correct items, rather than confusion between present and previous items.…

Two experiments showed the proportion of recalled words recognized to be higher than expected when the experiment was conducted under typical study conditions. Under special study conditions, the proportion of recalled words recognized more closely approximated expected values. Exceptions depend on encoding operations rather than on the properties…

In two experiments on free and cued recall, spacing between categorically related items, presentation rate and category size were varied and the effects on recall of items as a function of their serial order were studied. Results suggest subjects organize material during acquisition by retrieving and rehearsing previously studied items. (CHK)

One hundred forty-four subjects received 4 Brown-Peterson trials with recall triads from a common encoding category. Items on three trials were from a common subset, while on the fourth, the subset was shifted or not, and a cue was presented or not. The cue influenced response generation, a shift improved recall. (CHK)

Two experiments tested for effects of intralist cues upon recognition probability. Categorized and random lists were each tested, with targets appearing with zero, one or three intralist cues. Experiments showed substantial effects of trials and list type, but not of intralist context. (CHK)

Three experiments are described which support the hypothesis that in a lexical decision task, prefixed works are analyzed into their constituent morphemes before lexical access occurs. Results compare classification times of nonwords that are and are not stems, of free and bound morphemes, and of stems and control items. (CHK)

A task required subjects to make a word-nonword decision to visually presented items--words with a high or low number of meanings or lawful nonwords. Words with several meanings produced shorter decision times, indicating that words with multiple meanings have multiple memory entries. (CHK)

Three response measures that have been used in the study of temporal codes for memories were evaluated. Subjects were shown a list of words singly for study, and recency, position, and language judgements were obtained. (SW)
