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)

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

In order to examine the degree to which form perception affects the formation of apparent-motion experience, subjects were presented with nine ambiguous apparent-motion situations, where the elements of each single flash were various figures. (Editor)

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.…

Attempts to determine the extent that typicality effects obtained in previous research on natural semantic categories could be obtained in artificial categories purely as a function of structural principles when the frequency and nature of experience with items were controlled. (Author/RK)

Phonological fusion occurs when the phonemes of two different speech stimuli are combined into a new percept that is longer and linguistically more complex than either of the two inputs. The present article is an investigation of the conditions necessary and sufficient for fusion to occur. (Editor/RK)

This paper addressed itself to the general question of the depth of processing required for lexical decision. (Author/RK)

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…

The purpose of the present work was to investigate the relation between pattern goodness and accuracy of reproduction in backward masking. It may be hypothesized that good patterns, being easier to encode as wholes, will be reproduced more easily than poorer patterns. Four experiments were performed. (Author)

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…

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)

This paper describes and tests a two-stage model for a "semantic congruity effect" in comparative judgments. (Editor)

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)
