A different kind of pain: affective valence of errors and incongruence*

People hiss and swear when they make errors, frown and swear again when they encounter conflicting information. Such error- and conflict-related signs of negative affect are found even when there is no time pressure or external reward and the task itself is very simple. Previous studies, however, provide inconsistent evidence regarding the affective consequences of resolved conflicts, that is, conflicts that resulted in correct responses. We tested whether response accuracy in the Eriksen flanker task will moderate the effect of trial incongruence using affective priming to measure positive and negative affect. We found that responses to incongruent trials elicit positive affect irrespective of their accuracy. Errors, in turn, result in negative affect irrespective of trial congruence. The effects of conflicts and errors do not interact and affect different dimensions of affective priming. Conflicts change the speed of evaluative categorisation while errors are reflected in categorisation accuracy. We discuss the findings in light of the “reward value and prediction” model and the “affect as a feedback for predictions” framework and consider the possible mechanisms behind the divergent effects.     

Evaluating scientific research: Belief,hindsight bias,ethics, and research evaluation

Students may exhibit two forms of cognitive biases, belief and hindsight bias, in evaluating a scientific experiment. Counter to disagreement, they may only believe an outcome that agrees with their belief to be more predictable in hindsight than foresight. The focus of this research is on the relationship between these biases. Students were queried about their dichotomous beliefs (learned vs. genetic) about behavior for an animal experiment and then assigned randomly to a no‐outcome or genetic outcome condition. With agreement between students' belief and outcome, the findings revealed hindsight bias (foreseeability) supported by the outcomes for surprise, disappointment, ethics, and research evaluation. With disagreement, hindsight bias was trumped along with perceiving the experiment as being less ethical and scientifically sound. Regardless of the outcome, students seem to adhere to their beliefs. Hence, students may believe that the outcome is inconsequential because it is obvious or contrary to their beliefs.     

Biased recipients encounter biased sources: Effect of ethical (dis‐)agreement between recipient and author on evaluating scientific claims

Scientific claims that are connected to ethical concerns are frequently brought forward by communicators who are not ethically neutral. This study investigated how far recipients' evaluation of such claims is guided by vigilance toward a potential ethical source bias rather than their own ethical bias. One hundred ten individuals opposed to capital punishment read a topic‐related text by an ethically positioned source. A scientific claim in the text either supported or did not support the recipient's ethical stance; in addition, the source either shared or opposed their stance. Results showed that recipients are guided to some extent by their own ethically motivated reasoning: They agree more consistently with sources sharing their ethical stance and consider these sources to be more credible. Recipients appear to be principally aware that a source's ethical stance may bias its scientific message, but this vigilance seems to depend on their own ethical disagreement with the source.     

Initiation of joint attention and related visual attention processes in infants with autism spectrum disorder: Literature review

Autism spectrum disorder (ASD) represents a group of neurodevelopmental disabilities that can be difficult to identify before the age of 2 or 3 years, the age when the full range of behavioral symptoms has emerged in most cases. Initiation of joint attention is an important developmental function in which impairments are already observable before the second birthday and can predict children’s ASD symptomatology. In the first part of this review, we summarize results pertaining to retrospective studies of initiation of joint attention in children with ASD and prospective studies of infants at high risk for ASD during the first 2 years, when this behavior is becoming more complex in terms of frequency, quality, and variety. We will also discuss the implications of impairments in dyadic engagement, a precursor of joint attention behavior, for the early development of joint attention. Finally, the early development of initiation of joint attention has been related to specific visual attention mechanisms such as social orienting and visual disengagement. In the second part of this review, we provide an overview of the relationship between those visual attention mechanisms and subsequent social-communication impairments. Clinical and research implications of these findings for both early detection and early intervention will be discussed.     

Lucky joint action

In this paper, I argue that joint action permits a certain degree of luck. The cases I have in mind exhibit the following structure: each participant believes that the intended ends of each robustly support the joint action. This belief turns out to be false. Due to lucky circumstances, the discordance in intention never becomes common knowledge. However, common knowledge of the relevant intentions would have undermined the joint action altogether. The analysis of such cases shows the extent to which common knowledge of the participants’ intentions can be harmful to joint action. This extends a recent line of research that has questioned the necessity of common knowledge in joint action.

干扰素治疗慢性乙型肝炎临床评价

干扰素治疗慢性乙型肝炎已有20多年历史,由于其抑制病毒复制和强大的免疫调节作用,以及具有疗程确定,不引起病毒变异耐药,显效后疗效持久的特点,是慢性乙型肝炎抗病毒治疗的首选药物之一。多项试验证明聚乙二醇化干扰素治疗慢性乙型肝炎的疗效优于普通干扰素和核苷类似物。本文就有关干扰素单用、联合核苷类似物和序贯疗法治疗慢性乙型肝炎的临床研究和HBV基因型对干扰素疗效的影响做简要综述。     

生存质量在晚期肿瘤疗效评价中的思考

传统的肿瘤疗效评价方法多采用治愈率、生存率等指标来衡量。随着传统医学模式向生物一心理一社会医学模式转变,生存质量越来越受到重视。生存质量从一个新的角度评价治疗效果,更重视患者的主观感受,而不是仅将临床客观指标作为评价标准,能更客观地指导治疗方案的选择。     

Information distortion in the evaluation of a single option

Extending previous work on biased predecisional processing, we investigate the distortion of information during the evaluation of a single option. A coherence-based account of the evaluation task suggests that individuals will form an initial assessment of favorability toward the option and then bias their evaluation of subsequent information to cohere with their initial disposition. Three experiments tested this hypothesis. Initial disposition was manipulated (Studies 1 and 3) or measured (Study 2), and attribute ratings were collected as indicators of information distortion. Results from all three experiments indicate that attribute evaluations were biased to favor initial dispositions. These findings provide evidence that information distortion is one cause of primacy effects in judgment and decision-making settings involving a single option.     

心理治疗效果评定量表（简式）在中、德应用的心理测量学研究

419名中国和德国被试参加了本研究,并回答了若干简式心理健康量表。所选的这套量表能对心理治疗不同阶段的效果（Howard’s阶段模型：重新认识期-转变期-康复期）进行测查。本研究目的在于考察这些简式量表能否用于认知-行为治疗跨文化培训项目中的质量管理。结果显示,这些量表在中德两种文化背景下都有很高的信度和效度（聚合效度和敏感性）。尽管项目间的高相关似乎提示心理健康模型只有一个维度,但探索性因素和理论分析则更支持心理健康是一个分为8个亚维度的模型,其中每个亚维度或者与基础情绪、或者与社会性情感相连关联。本文最后就研究结果及其对心理治疗质量控制的意义进行了详细讨论
