A four-part experiment was carried out to study the relationship between the time course of object-feature perception and the time course of retrieval of object information from memory. The experiment consisted of 2 perceptual matching tasks, and 2 perceptual recognition tasks. In all 4 tasks, participants provided speeded judgments of the…

Article attempted to find whether there are experimental paradigms that can be employed to determine a sensory scale that is capable of accounting for judgments of differences, ratios, and similarities. (Author/RK)

A series of experiments was conducted to determine aspects of both perceptual and motor processing for the consonant cluster (st). (Editor)

In speech perception, the distinction between stop consonants and glides such as (b) versus (w) and (g) versus (j) can be signaled by variations in the rate and duration of the formant transitions. These experiments attempted to determine whether this rate and duration information is processed by a unitary analyzer for both labial ([b]-[w]) and…

In this article the authors examined three broad models for the congruity effect and tested them in a verification task. In so doing they attempted to learn something new about perceptual codes and perceptual judgments. (Author/RK)

The present experiment was intended as a further elaboration of the effects of nonphysically aversive stimulation on subsequent performance, in order to determine the applicability of the helplessness model to the human subject. (Author)

Studies of the psychology of hindsight have shown that reporting the outcome of a historical event increases the perceived likelihood of that outcome. Three experiments show that similar hindsight effects occur when people evaluate the predictability of scientific results. Implications for the evaluation of scientific research by lay observers are…

Examines the nature of perceptual mechanisms mediating kinetic depth effects by pitting one type of one-dimensional motion perspective against the other. (Author/RK)

These experiments pursued the idea that the detection of symmetry is accomplished by mental rotation to the vertical. They investigated the time it takes to decide whether or not a pattern is symmetrical as a function of the angular orientation of the pattern and the tilt of the subject's head. (Author/RK)

This paper described four experiments designed to provide insight into the mechanisms used to resolve difficult choices. (Author/RK)

The studies reported here asked: (a) How does receipt of outcome knowledge affect judgment? (b) How aware are people of the effects that outcome knowledge has on their perceptions? Answers to these questions will shed light on how people do learn and might better learn from history. (Author/RK)

The technique of priming was used to study the nature of the mental representations generated by color names. (Editor)

Is the perception of velocity determined by the prior discrimination of spatial and temporal distances? Two experiments sought to answer this question by comparing the discriminabilities of moving stimuli varied in spatial extent, temporal duration, or in redundant combinations of both variables.

When asked to report the first digit that comes to mind, a predominant number (28.4 percent) of the respondents choose 7. Three further experiments sought to establish whether this predominance is due to an automatic activation process or to a deliberate choice. (Editor)

Three experiments further explored the Avant, Lyman, and Antes finding that, during prerecognition processing, differences in subjects' familiarity with letters, words, and nonwords generate differences in the apparent duration of tachistoscopic flashes. (Editor)
