We examined whether 2 types of interpolated tasks (i.e., retrieval-practice via free recall or guessing a missing critical item) improved final recognition for related and unrelated word lists relative to restudying or completing a filler task. Both retrieval-practice and guessing tasks improved correct recognition relative to restudy and filler…

A fundamental property of human memory is that repetition enhances memory. Peterson and Mulligan (2012) recently documented a surprising "negative repetition effect," in which participants who studied a list of cue-target pairs twice recalled fewer targets than a group who studied the pairs only once. Words within a pair rhymed, and…

Despite the clear long-term benefits of spaced practice, students and teachers often choose massed practice. Whether learners actually fail to appreciate the benefits of spacing is, however, open to question. Early studies (e.g., Zechmeister & Shaughnessy, 1980) found that participants' judgments of learning were higher after massed than after…

Two experiments on how symmetrical difficulty factors (word familiarity and concreteness) affect stages of associative learning are reported. Learning parameters reacted in a qualitatively similar manner to stimulus and response manipulations. Paired associate items are represented in memory as unitary traces rather than as separate stimulus and…

Mild memory impairment was detected in 28% of a sample of healthy community-dwelling older adults using the delayed recall trial of a word list learning task. Statistical analysis revealed that individuals with memory impairment also demonstrated relative deficits on other measures of memory, and tests of executive function, processing speed and…

Reported an experiment on the effects of taxonomic organization on 7- and 11-year-olds' free and cued recall of two- and four-category lists. Analysis used a stages-of-learning model that simultaneously delivered estimates of the impact of these manipulations on storage and retrieval components of recall. (Author/CB)

Seventy-nine first-year and 85 third-year students were tested on the meanings of French words from vocabulary lists. Twenty percent were then taught memory-improvement strategies, 20 percent were taught strategies and given guided practice, and 20 percent learned the lists without aids. The strategies significantly improved the performance of…

Second-graders, fifth-graders, and adults participated in an experiment of cued recall for cue-target picture and word pairs. Results suggested that differences in the encoding of both specific and categorical attribute information contribute to developmental recall differences independently of encoding intent and stimulus modality.

It was hypothesized that freedom to choose words to be learned, but not the actual choice of words per se, improves performance in paired-associate tasks. Subjects offered an attractive or meaningful choice performed significantly better than subjects offered an unattractive choice, which was equivalent to no choice at all. (Author/CP)
