Involuntary attention and brightness contrast

Carrasco, Ling, and Read (2004) reported that involuntary attention increased perceived contrast. We replicated Carrasco et al. and then tested an alternative hypothesis: With stimuli near threshold, a peripheral cue biased observers to believe a stimulus had been presented in the cued location. Consistent with this hypothesis, the effect disappeared when we used higher-contrast stimuli. We further tested the guessing-bias hypothesis in three ways: (1) In a detection experiment, the cue affected bias, but did not increase d'; (2) when the cue followed the stimulus, we obtained the same results as when the cue preceded the stimulus; (3) in one experiment, some trials contained no stimulus, yet observers responded that the cued blank stimulus had higher contrast than the uncued blank stimulus. The results suggest that the effects of a noninformative peripheral cue are best described in terms of nonperceptual biases.     

腹腔镜在结直肠肿瘤手术中应用的回顾与思考

以腹腔镜为代表的微创外科技术迅速发展并取得了良好的临床效果.腹腔镜手术治疗结直肠癌存在较大争议,全盘否定或盲目应用都会影响腹部外科的发展.腹腔镜结直肠癌切除术都有其适应证并且对医生提出了更高的技术要求.随着腹腔镜技术的不断发展和完善,腹腔镜在结直肠癌手术的应用有广阔的发展空间.     

儿童归纳推理机制述评

在儿童早期归纳推理机制的探索过程中,一直存在着两种观点.一种认为儿童归纳推理是以类别或概念为基础的;另一种则认为儿童归纳推理是以相似性为基础的.这两种观点可能各自反应了儿童归纳推理的一个方面:前者可能说明的是儿童在知识丰富领域的归纳推理;而后者则可能说明的是儿童在知识贫乏领域的归纳推理.     

Mood specific media use and emotion regulation: Patterns and individual differences

The present study examines moods in which individuals are most likely to utilize various forms of entertainment media and the emotion regulation tendencies that are associated with such preferences. Results of a questionnaire study (n = 229) show that mood specific media use may be captured by three factors: turning to media in a positive mood, in a negative mood or in a bored mood. Findings also show that various forms of difficulty regulating emotion (e.g., feeling out of control when upset) predict media use in negative or bored moods only. More specific analyses show that music use in negative moods is predicted by both positive indices (e.g., reflection tendencies) and negative indices of emotion regulation (e.g., rumination tendencies), while television use in negative moods is only predicted by negative indices of emotion regulation. Results are discussed in light of the psychological needs that selective media use may serve.     

Money and fame: vividness effects in the National Basketball Association

In his widely reprinted paper “On the Folly of Rewarding A, While Hoping for B,” Kerr argued that vividness was one of the major reasons for distorted rewards. Using both archival and survey data, the present paper directly tests Kerr's proposal by investigating whether, how, and why highly visible behaviors are over‐rewarded and less visible, but similarly (or more) important behaviors are under‐rewarded. The National Basketball Association (NBA) was chosen as the domain of this study because scoring is particularly vivid, even though both non‐scoring and scoring performances are critical for winning games. Findings from four studies demonstrated that the scoring performance of NBA players was weighed more heavily than their non‐scoring performance. Scorers were rewarded with higher salaries and received more support in the NBA All‐Star balloting than defenders, even though they might not necessarily make more contribution than their teammates. This pattern of findings suggests that the vividness effect may lead to pronounced differences in people's judgments, especially when they face abundant real‐world information with similar validity.

共同方法偏差的统计检验与控制方法

共同方法偏差是心理学研究中一个越来越被关注的课题,但国内心理学界对其的介绍、研究还比较少,导致研究中对共同方法偏差的控制还有所欠缺。共同方法偏差的控制方法分为程序控制和统计控制,该文介绍了共同方法偏差的多种统计控制法,如因素分析法、偏相关法、潜在的误差变量控制法、结构方程模型法等,分析了其各自的优缺点,并提出了如何选择采用这些方法的建议.     

Counselor Trainees' Self-Statement Responses to Sexually and Physically Abused Clients,and Client Role Conflict

Because sexual abuse issues present a threat to counselor trainees, the authors predicted that trainees who expected to counsel a sexually abused client would respond with an increase in anxiety and negative self-statements. A total of 63 female trainees were assessed after viewing a videotape of a client reporting sexual abuse, physical abuse, or role conflict. Results indicated that, counter to predictions, the trainees who expected to counsel the sexually abused client increased their positive self-statements. Schwartz's (1986) States-of-Mind model was applied to the self-statement ratios, and, according to the model, trainees were unrealistically optimistic with respect to their counseling.
