Six experiments investigated how changes in stimulus speed influence subjective duration. Participants saw rotating or translating shapes in three conditions: constant speed, accelerating motion, and decelerating motion. The distance moved and average speed were the same in all three conditions. In temporal judgment tasks, the constant-speed…

The intriguing possibility has emerged that the mechanisms processing information concerning different attributes might arrive at incompatible conclusions, so that stimuli are perceived which have paradoxical properties. This study demonstrated just such a situation. (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)

In three experiments the location of pigeons was monitored during 20-second illuminations of a right or left key presented in various temporal relationships with food delivery. In general, subjects approached a signal positively correlated with food and withdrew from a signal negatively correlated with food. (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…

It is much easier to look for an unfamiliar character (such as an upside down A) embedded among familiar ones than to look for a familiar character (A) among unfamiliar ones. Furthermore, the nature of the background seems more important toperformance than the nature of the target. (Editor)

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

The concept of a scene schema was used to predict the kinds of information that will be remembered from complex pictures over relatively long periods of time. Recognition of eight types of transformations on both organized and unorganized pictures was tested either immediately following presentation or at intervals of a day, a week, or 4 months.…

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)

Represents a more complete test of Glanzer's model of memory than has been provided to date in that the overt rehearsal data offer a means of assessing whether subjects reorganize phonemically related items in short-term store. (Author/RK)

Previous research has investigated the effects of interpresentation lag within the context of experimenter-controlled lag values. The present study attempted to explore subject-controlled lag effects on paired-associate learning. (Editor)

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)

Authors examines the limits of selective attention during early stages of information processing. (Author/RK)
