Purpose: The aim of this study was to determine whether the word-learning challenges associated with developmental language disorder (DLD) result from encoding or retention deficits. Method In Study 1, 59 postsecondary students with DLD and 60 with normal development (ND) took the California Verbal Learning Test-Second Edition, Adult Version…

The effects of delaying an immediate test, a rehearsal opportunity, or a second presentation on long-term free recall were investigated in an experiment combining features of the Brown-Peterson and free-recall paradigms. A proposed model assumes that both repetitions and tests promote learning. (CHK)

When subjects are tested on ordered information, performance is better on inferences than on information actually presented during training. Humphreys suggested that superiority on inferences derives from differential frequency. This experiment refutes that position, demonstrating that superiority on inferences is observed even when frequency is…

Subjects were asked to encode and recall lists of words under the influences of marijuana and a marijuana placebo. Free recall was more complete when both encoding and recall were after marijuana use than in the encode-marijuana, recall-placebo state. Recall must depend on restoration of dissociated encoding state. (CHK)

This verbal memory study considers only simple sentences and examines learner performance under the two conditions of audio presentation and printed presentation. Learner performance is compared when required either to recognize sentences identical to those in the original list or, alternatively, to recognize non-identical sentences incorporating…

The effect of verbal labeling in a serial position short term memory task was investigated. Forty female college students were given 16 trials each. Eight trials involved only central items which had to be recalled. The other eight trials involved both central and incidental items. Half of the subjects verbalized the names of the central items as…

THREE GROUPS OF FIRST- AND SECOND-GRADE CHILDREN, TWO LOWER-CLASS AND ONE MIDDLE-CLASS, WERE ASKED TO LEARN AND RECALL SEQUENCES OF WORDS AT FOUR LEVELS OF CONCEPTUAL DIFFICULTY--NONSENSE SYLLABLES, HIGH FREQUENCY NOUNS, ANOMALOUS SENTENCES, AND MEANINGFUL SENTENCES. IT WAS HYPOTHESIZED THAT THE STUDENTS' VERBAL MEMORY WOULD INCREASE WITH…
