Processes contributing to matching-to-sample deficits were investigated with 22 moderately and severely mentally retarded adolescents. Although nonretarded subjects performed better on immediate and delayed retention tests, there was no difference in rate of forgetting, and rehearsal improved delayed test performance equally for both groups.…

The present experiments were designed to obtain further information on the forgetting of verbal items from STS when the interpolated activity is a very attention-demanding nonverbal task. (Author)

Decay and interference contribute to the short-term forgetting of retarded adolescents. (RL)

Forgetting in long-term memory, as measured in a recall or a recognition test, is faster for items encoded more recently than for items encoded earlier. Data on forgetting curves fit a power function well. In contrast, many connectionist models predict either exponential decay or completely flat forgetting curves. This paper suggests a…

In working memory (WM) span tests, participants maintain memory items while performing processing tasks. In this study, we examined the impact of task processing requirements on memory-storage activities, looking at the stimulus order effect and the impact of storage requirements on processing activities, testing the processing time effect in WM…

Performance on a wide variety of memory tasks can be hypothesized to be influenced by processes associated with controlling the contents of memory. In this project 328 adults ranging from 18 to 93 years of age performed six tasks (e.g., multiple trial recall with an interpolated interference list, directed forgetting, proactive interference, and…

It has long been known that acute marijuana administration impairs working memory (e.g., the discrimination of stimuli separated by a delay). The determination of which of the individual components of memory are altered by marijuana is an unresolved problem. Previous human studies did not use test protocols that allowed for the determination of…

Paraphrase, as it reflects the processes of remembering rather than those of forgetting, implies that language is best transmitted in one form and stored in another. The dual representation of linguistic information that is implied by paraphrase is important for storing information that has been received and for transmitting information that has…

The present paper asked whether certain sources of short-term forgetting, proactive interference and interpolated task difficulty, exerted their influences in STS, LTS, or both. (Author/RK)

The present experiment tested the hypothesis that learning under conditions of high arousal should lead to stronger permanent memory and weaker immediate memory than learning under conditions of low arousal. When digital vasoconstriction was used as the measure of arousal, the results confirmed the hypothesis. Learning under high and low arousal…

This Fastback contends that educators are in the memory business, that memory is probably our most maligned faculty, that forgetting is a fact of life, and that overall memory skills can be learned. The booklet addresses the following questions: How justified are people's complaints about memory? How much is myth and how much is fact? What memory…

The auditory/verbal short-term memory of 64 college students was examined across a wide range of retention intervals (5 seconds to 60 seconds). High attention during interpolated processing was ensured by monitoring rehearsal with a combination of methods, and errors were analyzed for evidence of proactive and intra-unit interference. Recall of…

Compares the rates of forgetting of five-item sequences of acoustically similar and dissimilar consonants and words in the absence of proactive and retroactive interference in order to test whether within sequence similarity rather than stimulus length would have a greater influence on retention. (Author/RK)

This paper reports two experiments investigating the effect of schooling and urbanization on short term recall and recognition memory. Subjects were 384 male children and young adults living in Morocco representing urban and rural and schooled and nonschooled backgrounds. Additional subject groups--including Koranic school students, Moroccan rug…

Previous research has indicated that for discretely (paired associate) as well as continuously (sound-film) presented information, high arousal during acquisition results in poor immediate recall, but is characterized by a strong reminiscence effect. Low arousal learning results in better immediate recall with poor retention. The hypothesis that…
