Neuroticism and extraversion as predictors of negative and positive emotional information processing: comparing Eysenck's,Gray's,and Newman's theories

This study compared how extraversion, neuroticism, and extraversion × neuroticism are related to processing of pleasant and unpleasant emotional information as predicted by Eysenck's, Gray's, and Newman's theories. Initially, the participants' levels of extraversion (as measured by the sociability subscale) and neuroticism were assessed with Eysenck's Personality Inventory. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant, and also neutral information. The results showed that extraversion was associated positively with the processing of pleasant information, while neuroticism was associated positively with the processing of unpleasant information. These findings support predictions from Eysenck's theory. Copyright © 2002 John Wiley & Sons, Ltd.     

Effects of workload preview on task scheduling during simulated instrument flight

Our study examined pilot scheduling behavior in the context of simulated instrument flight. Over the course of the flight, pilots flew along specified routes while scheduling and performing several flight-related secondary tasks. The first phase of flight was flown under low-workload conditions, whereas the second phase of flight was flown under high-workload conditions in the form of increased turbulence and a disorganized instrument layout. Six pilots were randomly assigned to each of three workload preview groups. Subjects in the no-preview group were not given preview of the increased-workload conditions. Subjects in the declarative preview group were verbally informed of the nature of the flight workload manipulation but did not receive any practice under the high-workload conditions. Subjects in the procedural preview group received the same instructions as the declarative preview group but also flew half of the practice flight under the high-workload conditions. The results show that workload preview fostered efficient scheduling strategies. Specifically, those pilots with either declarative or procedural preview of future workload demands adopted an efficient strategy of scheduling more of the difficult secondary tasks during the low-workload phase of flight. However, those pilots given a procedural preview showed the greatest benefits in overall flight performance.     

Axiomatization of ‘Peircean’ branching-time logic

The branching-time logic called Peircean by Arthur Prior is considered and given an infinite axiomatization. The axiomatization uses only the standard deduction rules for tense logic.     

Mindfulness‐Based Interventions in Counseling

Mindfulness is a relatively new construct in counseling that is rapidly gaining interest as it is applied to people struggling with a myriad of problems. Research has consistently demonstrated that counseling interventions using mindfulness improve well‐being and reduce psychopathology. This article provides a detailed definition of mindfulness, including a discussion of the mechanisms underlying mindfulness practice; explores the implementation of mindfulness as a counseling intervention; and examines literature supporting its effectiveness.     

Kant on Acting from Juridical Duty

ABSTRACT

A much debated passage in the Metaphysics of Morals often leads commentators to believe that it is not possible to act from juridical duty. On the one hand, Kant says that all lawgiving includes an incentive ‘which connects a ground to determining choice to this action subjectively with the representation of the law’ (MM: 218). On the other hand, he claims that juridical lawgiving ‘does not include the incentive of duty in the law’ (MM: 219). The first claim seems to entail that agents can perform a juridical duty for the sake of that duty; the second seems to entail that agents cannot perform a juridical duty for the sake of that duty. This paper shows that it is possible to reconcile both passages and to claim that one can act from juridical duty in Kant’s terms. First, it gives an account of what can be called the paradox of juridical duties. Second, it discusses briefly how responses to the paradox remain somewhat unsatisfactory. Finally, it clarifies how agents can act with no other incentive but the actual juridical duty without endangering the Kantian morality-law divide.     

Interaction of knowledge-driven and data-driven processing in category learning

The present paper argues that category learning is both a data-driven and a knowledge-driven process. This is described in a generic model that distinguishes between categorical knowledge, conceptual knowledge, and implicit cognitive theories. The model assumes that each of these knowledge aspects may affect the process of category learning by affecting the way similarities between objects are perceived. This central assumption of the model is tested in two experiments. The first experiment shows that the presence or absence of prior categorical and conceptual knowledge affects the psychological stimulus space by changing the saliency of the stimulus dimensions. The second experiment uses these weights to predict the distribution of errors over the stimuli and the number of trials to criterion in category learning by other participants under the same knowledge conditions. We conclude that prior categorical and conceptual knowledge affect category learning by mediation of similarity perception, and discuss the implications of these results.     

Treatment of panic disorder with agoraphobia: randomized placebo-controlled trial of four psychosocial treatments combined with imipramine or placebo

Few randomized controlled trials have included panic disorder patients with moderate to severe agoraphobia. Therefore, this population was studied using pharmacotherapy as well as psychotherapy. At the time of the study, imipramine was widely used as a pharmacological treatment. Also, current practice guidelines for patients with panic disorder find selective serotonin reuptake inhibitors and tricyclic antidepressants roughly comparable in terms of efficacy. Therefore, the main objective of this study is to compare four psychosocial treatments-cognitive and graded in vivo exposure treatments, graded in vivo exposure, cognitive treatment, and supportive therapy-to evaluate the benefits of combining cognitive therapy with exposure in vivo. These treatments were combined with imipramine or placebo for a total of eight experimental conditions. Participants presented moderate to severe agoraphobia. The method involved a randomized, double-blind, placebo-controlled trial with 137 participants who completed a 14-session protocol involving the treatments just mentioned. Measures were taken at baseline and posttreatment and at 3-, 6-, and 12-month follow-up. All treatment conditions were statistically and clinically effective in reducing self-reported panic-agoraphobia symptoms over the 1-year follow-up. No statistical differences were observed between imipramine and placebo conditions. This study found that all treatment modalities helped reduce panic and agoraphobic symptomatology over a 1-year follow-up period. These surprising results support the need to document the relations among the various components of an intervention. This would make it possible to assess the relative efficacy of the treatment components rather than of the intervention as a whole.
