Inhibition of return (IOR) is modulated by task set and appears later in discrimination tasks than in detection tasks. Several hypotheses have been suggested to account for this difference. We tested three of these hypotheses in two experiments by examining the influence of cue and target level of processing on the onset of IOR. In the first…

Psychological research has placed great emphasis on inhibitory control due to its integral role in normal cognition and clinical disorders. The stop-signal task and associated measure--stop-signal reaction time (SSRT)--provides a well-established paradigm for measuring response inhibition. However, motivational influences on stop-signal…

Two experiments investigated the effect of homograph stimuli in paired-associate transfer paradigms. (Editor)

Does similarity in the location and temporal intensity pattern of the CS and UCS permit more rapid conditioning despite the presence of stimulus pairings in all groups? The following experiments attempt to assess the role of such factors in determining the rate of acquisition of a conditioned emotional response. (Author)

Sixty males received either one, 5, or 9 electric shocks of varying magnitude from a confederate during a 10-trial probability estimation task. Following initial trials, subject and confederate reversed roles, and subjects were permitted equal opportunity to counter-aggress against the confederate. One-half the subjects had been forewarned of role…

The present research deals with the PRP effect as it occurs in a task involving response uncertainty that must be resolved on the basis of a decoding of each signal. (Author)

E. Hazeltine, D. Teague, and R. B. Ivry have presented data that have been interpreted as evidence against a central bottleneck. This article describes simulations of their Experiments 1 and 4 in the ACT-R cognitive architecture, which does possess a central bottleneck in production execution. The simulation model is capable of accounting for the…

The experiments reported here describe the relationships between the reflex-modulating effects of compounded stimuli and the effects of these stimuli when they act in isolation. (Author)

How can a person be induced to do something he might not ordinarily do? What constitutes a commitment on his part of some future action? Past research indicates that compliance with a small, relatively innocuous "foot-in-the-door" request serves to increase, relative to a control group, subsequent compliance with a larger request directed toward…

Article is a response to the contention that the inhibition associated with S is nonmonotonic with respect to non-reinforced trails. (Author)

This study examined whether dissonance is, phenomenologically, an aversive state. Experimental subjects were induced to write counterattitudinal essays under a high-choice condition. Evaluates subjects' reactions toward taking pills designed to bring about dissonance. (Editor/RK)

The commentary by S. T. Klapp (see record 2005-09704-010) on our recent article (A. Lleras & J. T. Enns, [see record 2004-21166-001]) proposes that the empirical finding of negative compatibility in masked priming be attributed to 2 distinct theoretical constructs: (a) perceptual priming through object updating, as described in our article, and…

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)

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)

A 2x2 factorial experiment was conducted to determine the effects of 2 interventions designed to reduce face-saving in a situation which normally produces such behavior. Face-saving, defined as sacrificing tangible (monetary) rewards to avoid public embarrassment, was measured by the length of time subjects publicly performed an embarrassing task.…
