The present study used segmentation (the insertion of spaces after the second and fourth letters of six-letter strings) to assess the effect of a configurational change on matching times for words and nonwords under different expectancy conditions. (Editor)

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…

How often are people wrong when they are certain that they know the answer to a question? The studies reported here suggest that the answer is "too often". The psychological bases for unwarranted certainty are discussed in terms of the inferential processes whereby knowledge is constructed from perceptions and memories. (Editor/RK)

The present study used videotaped horse races to test Kelley's attribution theory of the way people perceive the causes of behavior. (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)

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. (Editor)

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

Authors questioned whether the familiarity effect in the processing of words is a "perceptual" phenomenon or whether it is produced by visual rather than verbal mechanisms. (Author/RK)
