According to the hypothesis of a scalar property for time, the variability to time ratio should be constant. Three experiments tested the validity of this hypothesis in a restricted range of durations (standard values = 1, 1.3, 1.6, and 1.9 s). In each experiment, time intervals to be discriminated, reproduced, or categorized were presented with…

Forgetting what one was doing prior to interruption is an everyday problem. The recent soft constraints hypothesis (Gray, Sims, Fu, & Schoelles, 2006) emphasizes the strategic adaptation of information processing strategy to the task environment. It predicts that increasing information access cost (IAC: the time, and physical and mental effort…

A cognitive model of human learning with understanding is introduced. Empirical research supporting the model, which is called the generative model, is summarized. The model is used to suggest a way to integrate some of the research in cognitive development, human learning, human abilities, information processing, and aptitude-treatment…

Investigates the differences between rehearsal span and memory span and evaluates the research of Dalrymple-Alford (1967) on the part of rehearsal on reinforcing memory traces. (Author/RK)

Verbal memory was investigated using two miniature artificial languages that were identical except for the design of their reference system. One reference field was illustrated as a set of continuous elements, the other as a holistic unit. (Editor)

Subjects responded to pairs of test items from learned linear orderings (e.g., Tom is taller than Dick; Dick is taller than Sam, etc.). Results are compared with previous studies of ordered linguistic, perceptual, and numerical information. (Editor/RK)

Attempts to determine whether intentional forgetting instructions influence memory when the opportunity for rehearsal is restricted and whether the intentional forgetting phenomenon could be accounted for by a selective-search hypothesis which states that memory improvement is due to a smaller search set in the cued condition relative to the…

Seven-digit strings were presented for immediate recall. Before recall, subjects either read or retrieved from memory a single item (response prefix). Results were seen in terms of the sharing of the limited capacity of an active memory system by the memory series, the response prefix, and the operations to retrieve and emit the items. (Editor/RK)

Most studies of memory emphasize the direct encoding of physical stimuli. In contrast, this research investigates memory for the internal stimuli that are generated during processing of a presented stimulus. (Editor)

Three experiments were conducted to investigate whether semantic information presented to the unattended ear in a dichotic listening experiment has a memory effect after 30 seconds. (Editor)

In a series of three experiments on the role of memory in solving attribute-identification problems, the subjects did or did not have to remember their response and/or the stimulus for processing during any given intertrial interval. (Editor)

Investigates the relative importance that the eyes and mouth play in the representation in memory of a human face. Systematically applies two kinds of transformation--masking the eyes or the mouths on photographs of faces--and observes the effects on recognition. (Author/RK)

Study conducted while the author was the recipient of a National Institute of Mental Health Postdoctoral Fellowship and supported, in part, by an Office of Education Research Grant. (VM)

Three converging procedures were used to determine whether pictures presented in a rapid sequence at rates comparable to eye fixations are understood and then quickly forgotten. (Editor)
