Two experiments are reported investigating the effects of immediate recall upon subsequent recall and recognition of list items and examining the relation between positive and negative recency effects. (Author/RM)

Two experiments are reported in which subjects judged whether pairs of words viewed simultaneously contained the same stem morpheme. Reaction times for making these judgments are discussed. (Author/RM)

Four experiments are reported which investigate isolation effects in free recall. (RM)

Investigates the role of context in two forms of recognition memory. The first of these involves conscious memory, the second, which may or may not include conscious memory, is manifested by an improvement in performance which occurs when words are repeated in a variety of perceptual recognition and classification tasks. (Author/MES)

Effects of disambiguating prior contexts upon processing of lexical ambiguities in sentences were investigated. Subjects listened to lexically ambiguous sentences after a neutral or a disambiguating prior contest, and monitored for phonemes occurring immediately after each ambiguous word. Reaction times were significnatly longer following…

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)

Evidence supports the hypothesis that visual word recognition may involve recoding into phonemic form. Less pronounceable nonsense words are recognized as nonsense faster than those more pronounceable. Differences in pronounceability may produce their effects during sequencing of neural instructions of each phoneme. (CHK)

A set of experiments are reported in which it was found that most subjects were better at identifying both meaning and wording changes in concrete sentences and subjects took significantly longer to encode and decode the abstract sentences. Implications of these findings are discussed. (Author/RM)

Experiments explored the hypothesis that immediate memory span varies with length of recalled words. Relationships between memory and word length, temporal duration, reading speed and visual and auditory presentation were investigated. Results are interpreted in terms of a phonemically-based store of limited temporal capacity with varied…

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.…

This contradicts N. F. Johnson's arguments that word perception does not follow letter perception and that letter analysis awaits identification of the word as a unit. His experiments lack controls, and uncontrolled factors may contribute to his effects. Johnson's implications for prior-letter-processing models are contradicted. (CHK)

Describes an experiment designed to test predictions derived from a model of recognition memory that assumes no retrieval processes. It is argued that context effects do not necessarily imply retrieval processes in recognition. (Author/AM)

Three experiments are reported regarding reaction time. Letter comparison time was found to increase when other irrelevant letters were present, regardless of whether or not the letters made up a word or a word-like configuration. Word comparison time was found to increase when distractors were similar to targets. (Author/RM)
