The uniform principle assuming that comprehension precedes production in language acquisition was examined using Down's Syndrome children taught to comprehend singular/plural nouns and produce such forms for another noun. Three subjects reached criterion production first and one reached comprehension first, suggesting the modes can develop…

Listeners shadowed lists of words or parts of sentences, and shadowing latencies were recorded. The effect of attended context was interpreted as a result of strategical manipulation of response bias (a resource-limited process), whereas unattended context may be effective through spreading excitation in semantic memory (a data-limited process).…

A review of studies of word learning by normal adults and children, neuropsychological patients, and special development populations provides evidence that the phonological loop plays a crucial role in learning the novel phonological forms of new words, suggesting that the phonological loop stores unfamiliar sound patterns while more permanent…

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)

Definitions of four rare words were read to 259 undergraduates who were asked to record letters and syllables of the words, at the tip of the tongue. Results corresponded to an earlier study, with morpheme-like clusters evident. Results indicate an organizing memory system for words used in speech. (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.…

To understand the development of number-word construction, students in grades 1, 3, 5, and 7 named and counted from a set of numbers into the billions in two studies. Findings are discussed both in relation to children's growing knowledge of the number system and to vocabulary development. (Author)

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)
