Using a simple change detection task involving vertical and horizontal stimuli, I. M. Thornton and D. Fernandez-Duque (2000) showed that the implicit detection of a change in the orientation of an item influences performance in a subsequent orientation judgment task. However, S. R. Mitroff, D. J. Simons, and S. L. Franconeri (2002) were not able…

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)

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)

In this article it is argued that reading is faster than naming because printed words are more compatible with verbal responses than are objects. (Editor)

This study was designed to show that preferences for musical stimuli varying in complexity are in part determined by the range of complexity to which the subject adapts. (Author)

In two experiments the probabilistic properties of an internal (skill) task were simulated in an external (chance) task. (Editor)

The purpose of this study was to establish a theoretical framework for Stevens' empirically derived power law. Three models were proposed to explain the power law. (Editor)

The purpose of the present experiment was to compare the effects on performance and mood of reduced and extended sleep with those following temporal shifts of sleep in a single group of subjects who characteristically sleep 9.5-10.5 hours per night. (Author)

The main objective of the present investigations was to determine whether or not young human infants see the physical spectrum in a categorical fashion as human adults and animals who possess color vision regularly do. (Author)

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)

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 relatedness of four elements (tone, white noise, click, and a buzz) making up a recycled pattern was varied to determine the effects of streaming (sounds that break into separate channels) on the ease of correctly ordering the elements. Results suggest the organization of elements into streams by similarity supplants the organization by…
