Attention and Short-Term Memory in Normal Children,Aggressive Children,and Non-Aggressive Children with Attention-Deficit Disorder

In the present study, fifteen 7- to 9-year-old male school children with attention deficit disorder (ADD) as well as matched groups of aggressive and normal children were compared on scores obtained for initial acquisition of information and its maintenance in the short-term score under various attentional loads. Bi-colored, alphanumeric arrays were used in a partial-report technique. Retention was measured 0, 5, 10, and 20 s, after pre- and postexposure under both rehearsal and nonrehearsal conditions. ADD children (a) were deficient in original acquisition, (b) were unable to take sufficient advantage of decreased load conditions, and (c) showed decrements over time that paralleled those of the control group (CG). The results have been interpreted in light of maturational lag and the differences between ADD and aggressive groups.     

The Role of Individual Differences in the Accuracy of Confidence Judgments

Generally, self-assessment of accuracy in the cognitive domain produces overconfidence, whereas self-assessment of visual perceptual judgments results in under-confidence. Despite contrary empirical evidence, in models attempting to explain those phenomena, individual differences have often been disregarded. The authors report on 2 studies in which that shortcoming was addressed. In Experiment 1, participants (N = 520) completed a large number of cognitive-ability tests. Results indicated that individual differences provide a meaningful source of overconfidence and that a metacognitive trait might mediate that effect. In further analysis, there was only a relatively small correlation between test accuracy and confidence bias. In Experiment 2 (N = 107 participants), both perceptual and cognitive ability tests were included, along with measures of personality. Results again indicated the presence of a confidence factor that transcended the nature of the testing vehicle. Furthermore, a small relationship was found between that factor and some self-reported personality measures. Thus, personality traits and cognitive ability appeared to play only a small role in determining the accuracy of self-assessment. Collectively, the present results suggest that there are multiple causes of miscalibration, which current models of over- and underconfidence fail to encompass.     

Effects of Frustration Increase and Decrease on Percentage of Short Interresponse Times

The finding by H. L. Armus (1986) that short (less than 1 s) interresponse times (IRTs) occur with greater frequency at higher levels of required lever-pressing effort was investigated. It has been hypothesized that greater percentages of short IRTs at higher effort requirements are an expression of frustration (S. Boyer & R. Carroll, 1980); in the present study, between-groups manipulations of effort and reward combinations were made in an attempt to increase and decrease relative frustration and thereby increase and decrease percentages of short IRTs. The subjects were 17 experimentally naive, male Long-Evans rats. Manipulation of effort requirements and reward magnitudes yielded both an increase and a decrease in percentage of short IRTs. The rats switched from low effort and high reward to high effort and low reward demonstrated the greatest increase in percentage of short IRTs, whereas the rats switched from low effort and low reward to high effort and high reward demonstrated a decrease in short IRTs.     

When the Rule is Ruled Out: Exemplars and Rules in Decisions from Memory

What are the cognitive processes underlying people's decisions from memory? Previous research suggests that these processes can be best described by strategies that are based on abstract knowledge about the decision task (e.g., cue–criterion relations). However, recent results show that different cue presentation formats trigger the use of different decision strategies and that exemplar‐based strategies can account for memory‐based decisions as well. In three experiments, this effect was replicated, and mediation analyses identified the quality of the underlying knowledge representation as the critical variable that determines decision behavior. This supports the view that exemplar‐based reasoning is used as a backup system if cue abstraction is hindered. Copyright © 2012 John Wiley & Sons, Ltd.     

Young children's moral judgments of commission and omission related to the understanding of Knowledge or Ignorance

This study examined developmental change in young children's moral judgments of commission and omission related to mental states, especially knowledge or ignorance. 4–5 and 5‐ to 6‐year‐olds (n=67) made moral judgments about the tasks related to the understanding of knowledge or ignorance. The tasks were also composed of two types of acts: commission or omission. The results showed that the both age groups understood knowledge and ignorance, but that the older group made moral judgments based on this understanding more similar to adults compared to the younger group. There was not an age difference concerning whether the acts were of commission or omission. These findings indicate that there is no difference for young children in the difficulty in moral judgments of acts of commission and omission related to mental states, whereas there is a developmental difference in using the understanding of knowledge or ignorance for making moral judgments.

Memory for Actions of an Event: Older and Younger Adults Compared

Previous studies have shown increased false memory effects in older compared to younger adults. To investigate this phenomenon in event memory, in the present study, the authors presented younger and older adults with a robbery. A distinction was made between verbal and visual actions of the event, and recognition and subjective experience of retrieval (remember/know/guess judgments) were analyzed. Although there were no differences in hits, older adults accepted more false information as true and, consequently, showed less accurate recognition than younger adults. Moreover, older adults were more likely than younger adults to accompany these errors with remember judgments. Young adults accepted fewer false verbal actions than visual ones and awarded fewer remember judgments to their false alarms for verbal than for visual actions. Older adults, however, did not show this effect of type of information. These results suggest that aging is a relevant factor in memory for real-life eyewitness situations.     

跨文化的实证法学研究：文化心理学的挑战与贡献

跨文化的实证法学研究把文化心理学的理论突破和心理学的实证方法引入到对法学基本原理的研究之中。文化心理学研究中发现的东西方文化在价值定向、道德判断和思维方式等方面的差异能够给跨文化实证法学研究带来重要的启示。在对一些重要法律问题的认识上, 例如法律中的因果关系和责任的判定、合同形成以及纠纷调解等方面, 跨文化心理学研究已经发现了显著的跨文化差异, 这些差异可能会影响到不同文化背景的人对法的认识、法的建设以及法律的应用。我们认为跨文化的实证法学研究不仅可以为法学研究提供一条新的研究路径, 更主要的是还可以为中国法学研究的国际化和国际法律纠纷提供理论指导。     

意图信息在物权判断和道德判断中的作用

意图会影响人们的道德判断,但尚不清楚意图在物权判断中的作用。本研究以266名非法学专业的大学生为被试,通过包含不同意图（恶意/善意/无意）的故事情境,考察了在损失求偿和获益分享情境中人们的物权判断和道德判断。结果发现,在损失求偿情境中,不管是出于善意、恶意还是无意,被试均判断行为者应当赔偿他人损失,但不认为无意的行为者应受谴责。在获益分享情境中,被试认为善意的行为者应分享给他人带来的收益且应受赞扬,但恶意的行为者不应分享收益和受赞扬。综合来看,物权判断比道德判断较少受意图信息的影响,反映人们的物权判断具有领域特异性。     

An Examination of the Effects of Sport Involvement on Ethical Judgments in Sport and Business

Popular press headlines frequently reveal unethical or illegal activity in business and sports. Given these parallel ethical lapses in business and sport, our study examines potential relationships between student sport involvement (active and passive) and ethical judgments regarding issues in sport and business. Our results, based on a sample of 202 undergraduates in an upper-division management class, indicate a significant negative relationship between high passive sport involvement and ethical judgments about sport issues as well as a consistent significant positive relationship between female gender and ethical judgments about sport and business issues.     

Dispositional mindfulness,insomnia, sleep quality and dysfunctional sleep beliefs in post-treatment cancer patients

Dispositional mindfulness, or the tendency to be more mindful in daily life, has been associated with better psychological functioning and reduced overall distress. This study investigated the degree to which dispositional mindfulness was associated with sleep disturbances in cancer patients with insomnia. Further, we examined whether levels of mindfulness moderated the relationship between stress levels, mood disturbance, insomnia severity, sleep quality and dysfunctional sleep beliefs. Participants (N = 111) were adults who had been previously treated for cancer and currently met diagnostic criteria for insomnia. Higher levels of acting with awareness, non-judging and non-reacting were associated with better sleep and psychological outcomes. Despite these significant associations, mindfulness facets did not significantly moderate the relationship between stress, mood and sleep outcomes. This negative finding raises the possibility that increased mindfulness may not act directly to improve psychological outcomes, but rather through a series of other cognitive and affective changes. Our results emphasize the importance of addressing mood symptoms and stress appraisals as predictors of sleep disturbance in cancer patients.
