The current research evaluated the extent to which the grain size of recall practice for lengthy text material affects recall during practice and subsequent memory. The "grain size hypothesis" states that a smaller vs. larger grain size will increase retrieval success during practice that in turn will enhance subsequent memory for…

Previous studies have suggested that both automatic and intentional processes contribute to the learning of grammar and fragment knowledge in artificial grammar learning (AGL) tasks. To explore the relative contribution of automatic and intentional processes to knowledge gained in AGL, we utilized dual-task methodology to dissociate automatic and…

We aimed to clarify the importance of early visual processing deficits for the formation of cognitive deficits in the schizophrenia spectrum. We carried out an event-related potential (ERP) study using a computerised delayed matching to sample working memory (WM) task on a sample of volunteers with high and low scores on the Schizotypal…

We examined associative and item recognition using the maintenance rehearsal paradigm. Our intent was to control for mnemonic strategies; to produce a low, graded level of learning; and to provide evidence of the role of attention in long-term memory. An advantage for low-frequency words emerged in both associative and item recognition at very low…

Using a procedure of Hay and Jacoby [Hay, J. F., & Jacoby, L. L. (1999). "Separating habit and recollection in young and older adults: Effects of elaborative processing and distinctiveness." "Psychology and Aging," 14, 122-134], Korsakoff patients' capacity to encode and retrieve elaborative, semantic information was investigated. Habits were…

The authors present 2 experiments that establish the presence of knowledge partitioning in perceptual categorization. Many participants learned to rely on a context cue, which did not predict category membership but identified partial boundaries, to gate independent partial categorization strategies. When participants partitioned their knowledge,…

The hypotheses of this study include: (1) intentional forgetting, operationalized by a forget signal, will produce augmented recall; (2) highly organized groups of sentences will produce the best recall; and (3) anxiety state will produce a complex interaction with the forget signal and degree of organization variable on the amount of materials…

This study is concerned with the actual and potential memorizing strategies available to five-year-old children. A factorial design was employed with two conditions of presentation (blocked/random) combined with two conditions of recall (cued/uncued). The authors conclude that these children suffer from production deficiency rather than mediation…

A description of four experiments confirming the theory that recall of a given item from a semantically categorized list is impaired by the presence of other items from this same category. This inhibitory effect of part-set "cuing" is interpreted here as a cue-overload effect. Selected references are included. (AMH)

One hundred forty-four subjects received 4 Brown-Peterson trials with recall triads from a common encoding category. Items on three trials were from a common subset, while on the fourth, the subset was shifted or not, and a cue was presented or not. The cue influenced response generation, a shift improved recall. (CHK)

A description of a series of six experiments dealing with human memory processes. They examined the types of codes generated in maintenance rehearsal and the effects of rehearsal time at various single levels of encoding. Data confirmed earlier findings and led to conclusions regarding repetition, encoding and levels of processing. (AMH)

While mnemonic systems have been taught and used for hundreds of years, virtually all of the experimental research into such systems has been conducted since 1965. This paper describes four mnemonic systems, all of which rely heavily on visual imagery, and summarizes research conducted on the performance values of each system. The link system, the…

The comprehension and recall of instructional text is heavily dependent upon the contexts in which information input and retrieval occur. College students (N=44) recalled the contents of a hierarchically structured text immediately after study and again six weeks later. Total meaningful recall was better when the superordinate concepts, or cues,…

Ratcliff's theory of memory retrieval which posits parallel processing and Sternberg's serial processing explanation of memory scanning are reviewed and contrasted. Discrepancy between the two theories may arise because they focus on different aspects of the data. If scanning without comparisons takes place, the two views may be reconciled.…

Discusses the value of memorized factual material in science. Describes the use of mnemonic devices to facilitate memorization. Provides a list of 14 mnemonic devices commonly used in science other than ROY G. BIV, which is used to remember the colors of the visible spectrum. (CW)
