It was hypothesized that a moving or stationary observer who samples an ambient optic array specific to egomotion over a flat plain obtains a phenomenal experience of egomotion over that environment and further that the focus of expansion need not be present in the optic array sample for an observer to perceive his heading and egomotion.…

In a recently reported study, the functional components of imagery and vocalization strategies in children's verbal discrimination learning were examined, following the combined experimental/correlational logic of Underwood. The present research extends those results to a strategy that (unlike imagery and vocalization) has a positive influence on…

The major concern of the present experiment was to determine whether increased covert rehearsal is the sole cause of the release from proactive interference in short-term memory. (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)

Attempts to settle the question of whether reading units are ever larger than letters and considers the variables expected to influence the size of the reading unit. (Author/RK)

In the first of two experiments investigating the inhibitory effect of cuing, the taxonomic frequencies of cue words and critical words were manipulated orthogonally. (Editor)

Tulving and Thomson's encoding specificity effect was examined as a function of grammatical class and concreteness of the cues. (Editor)

Evidence for the hypothesis that the appearance of visually presented words is stored in "literal copy" form is critically evaluated and shown to be inconclusive. An experiment in which students were required to retain information about zero, one, or two visual properties of words is reported. (Editor)

This research investigates why it is that the more concrete the subject noun phrase of a sentence, the more likely the predicate is to be recalled when the subject noun phrase is the cue. (Editor/RK)

Recent research has suggested that outcome feedback is not the optimal form of feedback for learning complex interference tasks. The present experiment was designed to test the effects of outcome feedback against cognitively oriented feedback in a number of linear tasks. (Editor)

A series of experiments demonstrate that (a) temporal and spatial structures may be coded independently of one another, (b) linguistic materials lead to temporal superiority whereas pictorial forms give rise to temporal/spatial equality, (c) imposed encoding strategies do not influence the above patterns, and (d) imaginal processing does not…

If intentional forgetting is to be understood, research must focus on the specification of exactly how memory search and decision processes are altered when a subject is instructed to forget. This research addresses that problem. (Author/RK)

It is a common assumption that memories consist of sets of interrelated features of attributes. Rigorous and direct investigation of the functional properties of these sets has been relatively neglected. Questions whether the interrelationships of different components are reflexive or asymmetric and how components interact when more than one is…

Four experiments gave direct tests of a popular hypothesis about the role of classical conditioning in person perception and social judgment. (Editor)

Attempts to help specify the boundary conditions for use of the recognition-recall method, i.e., recall made conditional upon recognition, and to use this method to evaluate a hypothesis about stimulus-concreteness effects with low-meaningful responses. (Author/RK)
