When are semantic targets detected faster than visual or acoustic ones?

Duration-discrimination data from an experiment using empty auditory intervals in a two-alternative forced-choice paradigm are presented. The observed functional relationship between standard deviation of the psychometric density function and stimulus duration is shown to be fit significantly better by a Weber’s law model of duration discrimination than by Creelman’s counter model. Both models fail to predict the rapid rise in the Weber fraction observed for durations longer than about 2 sec. However, the Weber’s law model, based on a generalization of Weber’s law, accurately predicts the initial drop in the Weber fraction for very short durations and the observed constancy of the Weber fraction for durations up to 2 sec.     

The Development of Ethics: A Historical and Critical Study

Editor's Introduction When Oxford University Press sent us the three enormous volumes of Irwin's The Development of Ethics, we had two thoughts: First, the book is very important and demands a review; second, since human sacrifice is abolished in North America, it will be very difficult to find a reviewer. We handed the volumes to several interested persons, who in the end returned the books saying the task was beyond them. Then, my wife, a lifetime worker at that center of communal thought, the United Nations, suggested that we form a team to review the book. We put an announcement out on the Web, asking for reviewers to do a chapter each, at 250 words a review. We got several hundred volunteers, and chose 82 to review the 96 chapters of Irwin (reviewers got the chapters in Portable Document Format [PDFs], kindly supplied by Oxford). We got 81 of 82 reviews, 75 before the deadline, six slightly later. For purposes of completeness, I filled in the sole missing review. Would that the students in my seminars were so punctual! I would like to thank Elyse Turr at Oxford University Press for the PDFs, and my 82 reviewers for their expertise and diligence. I am grateful to all the volunteers who showed an interest in this strange and perhaps unprecedented project, and who patiently endured the vetting process. Special thanks is due to Laura di Summa, who coordinated all the pieces of this incredible puzzle. Did we accomplish something, something new, by mobilizing 82 minds to review one book? I hope so, but I can now only say what they say on television: “America, it's up to you.”     

When and how is job embeddedness predictive of turnover? A meta-analytic investigation

The present meta-analytic study introduces an overall model of the relationships between job embeddedness and turnover outcomes. Drawing on 65 independent samples (N = 42,907), we found that on-the-job and off-the-job embeddedness negatively related to turnover intentions and actual turnover, after controlling for job satisfaction, affective commitment, and job alternatives. In addition, the negative relationships between on-the-job embeddedness (off-the-job embeddedness) and turnover criteria were stronger in female-dominated samples and public organizations (collectivistic countries). Finally, turnover intentions, job search behavior, and job performance fully (partially) mediated the effect of on-the-job embeddedness (off-the-job embeddedness) on actual turnover. The research and practical implications of our findings are noted, in light of study limitations and future research needs. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Connectionism and the Philosophical Foundations of Cognitive Science

This is an overview of recent philosophical discussion about connectionism and the foundations of cognitive science. Connectionist modeling in cognitive science is described. Three broad conceptions of the mind are characterized, and their comparative strengths and weaknesses are discussed: (1) the classical computation conception in cognitive science; (2) a popular foundational interpretation of connectionism that John Tienson and I call "non-sentential computationalism"; and (3) an alternative interpretation of connectionism we call "dynamical cognition." Also discussed are two recent philosophical attempts to enlist connectionism in defense of eliminativism about folk psychology.     

Neuropsychological Performance in Gulf War Era Veterans: Motivational Factors and Effort

Assuming that the underlying etiology of unexplained health-related symptoms in returning Gulf War (GW) veterans is multifactorial, the possible role of feigning or exaggeration of symptoms is worth consideration as a contributing factor. The present study assessed the relationship between motivation to perform well during neuropsychological assessment and objective neuropsychological test performance. Motivation was measured as the score on a visual memory task (Test of Memory Malingering, TOMM) of low difficulty. Participants included 77 veterans from the cohorts of GW- (n = 58) and Germany-deployed (n = 19) GW-era veterans described in two other papers in this issue who were administered the TOMM. Most veterans earned perfect or near-perfect scores on the TOMM (48–50/50). Scores 47 were associated with lower scores on neuropsychological tasks assessing attention, executive functions, and memory. Variability in test performance within and between tasks measuring similar functions was also found in participants with lower TOMM scores.     

Adult ADHD and/or Sleep Apnea? Differential Diagnostic Considerations with Six Case Studies

An increased interest in the persistence of attention-deficit hyperactivity disorder (ADHD) into adulthood brings concern that adult ADHD may become overdiagnosed. As with ADHD in childhood, various other adult psychological and medical disorders may be associated with ADHD in adulthood, and these related disorders may be mislabeled and mistreated as simple ADHD. One such medical condition is sleep apnea. This paper reviews similarities and differences between ADHD and sleep apnea and presents case histories of six adult patients diagnosed with ADHD who were subsequently found to have at least comorbid obstructive sleep apnea (OSA). Clinicians who diagnose and treat patients with ADHD are advised to become familiar with sleep apnea as a life-threatening condition that presents with overlapping symptoms.     

Dealing with Poor Performance: Supervisor Attributions and the Cost of Responding1

The Green and Mitchell (1979) model of the process by which supervisors diagnose and deal with the causes of subordinates' poor performance is based upon attribution theory. The notion is that the supervisor makes an attribution about the cause of the poor performance and then selects an appropriate response or solution to deal with the problem. Two ways in which this can lead to an inapprorpriate solution are, first, a bias toward making internal attributions and, second, an aversion to using costly, even though appropriate, solutions. This study demonstrates that it is possible to prompt participants to make more external attribution about poor performance. It also demonstrates that whichever attributions they make (either internal or external), the solutions they select to deal with the poor performance are congruent with their attributions provided that the solutions do not have explicit implementation costs associated with them. However, when implementation costs are made explicit, costs influence solution selection and reduce the congruence between the attributions and the selected solutions. The possible implications of this finding for success in dealing with poor performance are discussed.     

Sensation seeking and selective attention: focused and divided attention on a dichotic listening task.

Differences in selective attention as a function of sensation seeking, extraversion, neuroticism, and psychoticism were examined in 108 undergraduates using a dichotic listening task. Dependent measures included shadowing performance, reaction times to a secondary light task, target detection, and recall. The results suggested that high sensation seekers have better focused attention than low sensation seekers, and these effects were strongest on the 1st trials of the shadowing tasks. High sensation seekers did not attend differently than low sensation seekers to words related to their interests (sexual, violent, or drug related). Extraversion was associated with greater recall of these kinds of words, although there were no overall differences in selective attention as a function of Eysenck's dimensions. The role of arousal in personality and attention is discussed, particularly in regard to the response of sensation seekers to task novelty.     

Psychological treatment of eating disorders

Significant progress has been achieved in the development and evaluation of evidence-based psychological treatments for eating disorders over the past 25 years. Cognitive behavioral therapy is currently the treatment of choice for bulimia nervosa and binge-eating disorder, and existing evidence supports the use of a specific form of family therapy for adolescents with anorexia nervosa. Important challenges remain. Even the most effective interventions for bulimia nervosa and binge-eating disorder fail to help a substantial number of patients. A priority must be the extension and adaptation of these treatments to a broader range of eating disorders (eating disorder not otherwise specified), to adolescents, who have been largely overlooked in clinical research, and to chronic, treatment-resistant cases of anorexia nervosa. The article highlights current conceptual and clinical innovations designed to improve on existing therapeutic efficacy. The problems of increasing the dissemination of evidence-based treatments that are unavailable in most clinical service settings are discussed.
