Representational masking and the attentional blink

After successful detection of a target item within a stream of rapidly displayed visual stimuli, subsequent detection of an additional target is impaired for roughly 500 ms. This impairment is known as the “attentional blink” (AB). Previous studies have found that if either the first (Tl; Raymond, Shapiro, & Arnell, 1992) or second target (T2; Giesbrecht & Di Lollo, 1998) is not followed by a mask, the AB impairment is significantly reduced. Whereas low-level perceptual factors have been found to influence the efficacy of masking in the AB (e.g., Seiffert & Di Lollo, 1997), the current experiment used a higher level (representational) manipulation, i.e., repetition blindness to reduce the efficacy of target masking in the AB. These findings contribute to the growing literature suggesting that masking plays more than a perceptual role in the AB phenomenon.     

Exercise type relates to inhibitory and error processing functions in older adults

ABSTRACT

This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.     

Delusion,Dissociation and Identity

Abstract

Envy and resentment are generally thought to be unpleasant and unethical emotions which ought to be condemned. I argue that both envy and resentment, in some important forms, are moral emotions connected with concern for justice, understood in terms of desert and entitlement. They enable us to recognise injustice, work as a spur to acting against it and connect us to others. Thus, we should accept these emotions as part of the ethical life.     

Activity experiences shape perceived fitness trajectories: Results from a 6-month randomized controlled trial in older women

ABSTRACT

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70–93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities.     

Abstract construals make the emotional rewards of prosocial behavior more salient

Although previous research has shown that helping others leads to higher happiness than helping oneself, people frequently predict that self-serving behavior will make them happier than prosocial behavior. Here, we explore whether abstract construal – thinking about an event from a higher level, distanced perspective – influences predictions about how rewarding prosocial actions will be for people’s own well-being. In Experiment 1, Hurricane Katrina volunteers who adopted an abstract construal predicted that their efforts would be more rewarding than did volunteers who adopted a concrete construal. Experiment 2 provided a conceptual replication with a hypothetical donation scenario; people who adopted an abstract rather than concrete construal predicted that giving more money would be more rewarding than giving less. These findings suggest that people are more likely to appreciate the emotional benefits of prosocial actions when they adopt high-level construals than when they adopt low-level construals.     

不同年级学生自然阅读过程信息加工活动特点研究

探讨不同年级学生自然阅读过程的信息加工活动特点,包括两个实验。实验１结果表明,低年级学生自然阅读后再复述文章时需要重读原文的时间比高年级学生要多,据此初步推知,低年级学生自然阅读过程可能主要是单一的语言解码信息加工活动,高年级学生自然阅读过程可能同时进行了语言解码与组织连贯的信息加工活动,以后者为主。实验２比较不同年级的学生在自然阅读、理解任务阅读与记忆任务阅读三种情况下对文章信息保持的效果,结果     

提取练习在记忆保持与迁移中的优势效应：基于认知负荷理论的解释

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明：(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用：在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。

Meaningful patterns of activity amongst the long‐term inner city unemployed: a qualitative study

A number of studies have sought to establish the social psychological factors involved in the maintenance of active lifestyles during long‐term unemployment. The aim of this study was to describe and account for the development and maintenance of different patterns of activity, with reference to their perceived meaningfulness. This was undertaken with a sample of Birmingham's inner city, long‐term unemployed population recruited from three inner city Jobcentres, including men and women, and White, Asian and African Caribbean participants (N = 24). Interviews were conducted using a semi‐structured interview guide. Using the qualitative software program, NUD.IST, the data were analysed according to the principles of the grounded theory approach. Activities were characterized as: domestic; educational; work‐like; socializing; and none. A model of meaningful activity in the context of formal unemployment was developed. The main components of the model were: features of formal employment that inhibited participants' engagement in it; the requirements for personal meaningful activity (challenging activity, effort and commitment, and being valued by others); the consequences of meaningful activity (opportunities for self‐determination and self‐development, and achievement, competence, and confidence) and consolidating factors (social comparison, self‐appraisal, religious and political beliefs, and social support). Theories of unemployment of Jahoda, Warr, and Fryer are considered in the light of the present findings. Copyright © 2002 John Wiley & Sons, Ltd.     

Effects of Organizational Level and Gender on Stress in the Workplace

Occupational stress adversely affects productivity, absenteeism, and job turnover, and contributes to health-related problems. The effects of organizational level and gender on the specific sources of occupational stress assessed by the Job Stress Survey (JSS) were evaluated for a heterogeneous sample of 1,791 working adults (860 males, 931 females) employed in 2 industrial companies and a large state university. Significant main or interactive effects of organizational level and/or gender were found for the JSS Item Index, Severity and/or Frequency scores of 29 of the 30 JSS items. Organizational level effects were both more numerous and larger in magnitude than gender effects. Employees at higher organizational levels reported that they experienced stress more often while making critical decisions and dealing with crisis situations than did workers at lower levels, for whom inadequate salary and lack of opportunity for advancement were more stressful. For males, work stress was more strongly related to concerns about their role in the power structure of an organization, whereas female employees reported experiencing more severe stress when there was a conflict between job requirements and family relationships.
