The time course of the spread of activation in lexical memory was studied using naming latency as the measure of activation in a variable-duration priming paradigm. (Editor)

A two-process theory of the spacing (lag) effect in free recall is presented and tested. (Editor/RK)

Research suggests that we process information by way of two distinct and functionally separate coding systems. Their location, somewhat dependent on cerebral laterality, varies in right- and left-handed persons. Tests this dual coding model. (Editor/RK)

In secondary-task reading experiments, easy text filled cognitive capacity more completely than difficult text. A cognitive interpretation is that, in reading easy passages, the cognitive processors are full. But in difficult passages, frequent breakdowns in comprehension temporarily empty processor spaces, leaving cognitive capacity for the…

Undergraduates were induced to expect a recall or recognition test and then to remember a critical list consisting of both high-frequency and low-frequency words. Groups received either an expected or unexpected recall or recognition test. People expecting recall did better, especially with high-frequency words. (Author/RD)

The spread of encoding concept was tested visually by having subjects view pictures which varied in contour completeness. The hypothesis was supported that as contour completeness decreased, the amount of perceptual analysis and memory performance would increase. (Author/MH)

The results of two experiments were generally in substantial agreement with the idea that part-list cues or context words exert their damaging effect by competing with target words at retrieval. (Editor)

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)

Subjects learned one, two, or three verbal lists simultaneously. Recall of the common list after 24 hours increased directly as the number of lists learned simultaneously increased. Assuming that simultaneous learning reduced interference, the interference was from extraexperimental sources of a proactive nature. (Author/CP)

Synonyms within languages were compared with exact repetition of words as aids to recall. Interlingual synonyms had effects identical to those of exact repetition, whereas intralingual synonyms were less effective than exact repetition. Bilingual equivalence of words does not appear to be due to common underlying semantic structures. (Author/RD)

A multirate mathematical model is presented to support the hypothesis that different types of information are lost from a memory trace at different rates. The model is validated by two experiments assessing the retention of pictures and of sentences at three different delays by cued recall. (Author/CP)

The effects of semantic (S), orthographic (O), and unrelated (U) verbal stimuli on word retrieval were examined. S stimuli inhibited locating items within categories, whereas U stimuli inhibited locating the appropriate category. The discrepancy between the present outcome and the previous finding of S prime retrieval facilitation is discussed.…

The fan effect (the difficulty in retrieving any one fact after learning many about a concept) occurs only when the facts with repeated concepts are stored as independent episodes. It tells us nothing about the code formed by a pattern of interconnected concepts. (Author/CP)

Second-grade students' reading proficiency was studied by determining the influence of rhyming or nonrhyming items on their recall of random letter strings, using visual and auditory presentations. Good and poor readers differed in their use of phonetic coding in working memory. (MH)
