理性行动-社会认同整合性集体行动模型

为探究理性行动理论和社会认同理论两大社会心理学宏论对于个体集体行动参与倾向的共同解释力,以“中日撞船事件”为考察蓝本向天津市431名大学生被试进行调查研究,结果发现：效能和社会规范作为态度和行动倾向的中介变量,在不同情境下对行动倾向的作用不同,符合理性行动原则;内部动机作为态度和效能、社会规范之间的中介变量,并受到学校认同和国家认同的直接或间接影响,支持了社会认同理论对遵从规范行为的解释;回归分析验证了不同水平认同对行动倾向作用程度的差异,整合模型则揭示了其具体的作用路径和影响机制.结论：理性行动理论与社会认同理论可彼此互补成为集体行动参与的整合性解释框架.

Psychiatric Distress and Suicidal Tendencies in Adult Cancer Survivors: Verifying the Validity of the Brief Symptom Inventory-18 for Identifying Suicidal Ideation in the Hospitalized Population of Mainland China

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychiatric distress but has not been verified in the Chinese population. From March to April 2019, 293 hospitalized cancer patients, aged 20–87, completed the cross-sectional survey with demographics questionnaire, BSI-18, and PHQ-9. We analyzed the single suicide-related item of PHQ-9 with the full score clinical outpoint for BSI-18 and PHQ-9 using SPSS 22.0 and R 2.15, including Pearson's χ² test and ROC curve analyses. A Pearson's χ² test was carried out to compare the three different methods with the gold screening criteria. The p-value was correspondingly to .006, .066, .838. When the PHQ-9?≥?10 criteria for the BSI-18, receiver operating characteristic analysis revealed that AUC values were 0.839, optimal cut-off points for both BSI-18?≥?50, the sensitivity of 85.8%, and 62.5%, respectively. The BSI-18 is suitable for a screening tool for psychological distress and could also be used in clinical settings for preliminary screening of hospitalized cancer patients.

面孔生命性加工的时间进程：ERP研究

本研究采用事件相关电位技术,通过参数设计考察了大脑加工面孔生命性时的神经电活动动态进程。结果显示：非生命性面孔比生命性面孔在中央顶区诱发了更大的LPP波幅;生命性和非生命性面孔诱发的LPP波幅均显著大于中间等级（60%）面孔,提示随生命性信息增强,LPP波幅呈“U”型变化。P1和N170未表现出面孔类别差异。结果表明LPP是探测面孔生命性加工的有效成分,支持面孔生命性加工位于面孔加工的晚期阶段的观点。

The Effects of Goal Distance and Value in Escalation of Commitment

Escalation of commitment describes individuals’ tendencies to spend resources beyond the point of rationality in order to persist in a chosen course of action, and most believe that sunk cost is the primary cause. However, it has been noted that sunk costs are confounded with progress made toward a goal, and that sunk costs do not affect individuals’ tendencies to escalate as all economic information is ignored in pursuit of the goal. Thus, the apparent escalation tendency may be a consequence of goal proximity instead of sunk costs. In Experiment 1, I show that individuals’ tendencies to escalate reflect the goal-gradient effect after controlling for the sunk costs. Experiment 2 provides a psychological process model to explain why goal-gradient influences individuals’ tendencies to escalate commitment by demonstrating that as individuals progress toward their goal, they exaggerate the value difference between the object that they are pursuing and the object that they are not pursuing. This perceived value difference, in turn, influences individuals’ tendencies to commit escalation of commitment. Results suggest a new interpretation for escalation of commitment and new approaches to guiding people to avoid it.     

Distinguishing the time course of lexical and discourse processes through context, coreference, and quantified expressions

How does prior context influence lexical and discourse-level processing during real-time language comprehension? Experiment 1 examined whether the referential ambiguity introduced by a repeated, anaphoric expression had an immediate or delayed effect on lexical and discourse processing, using an eye-tracking-while-reading task. Eye movements indicated facilitated recognition of repeated expressions, suggesting that prior context can rapidly influence lexical processing. However, context effects at the discourse level affected later processing, appearing in longer regression-path durations 2 words after the anaphor and in greater rereading times of the antecedent expression. Experiments 2 and 3 explored the nature of this delay by examining the role of the preceding context in activating relevant representations. Offline and online interpretations confirmed that relevant referents were activated following the critical context. Nevertheless, their initial unavailability during comprehension suggests a robust temporal division between lexical and discourse-level processing.     

A query theory account of the effect of memory retrieval on the sunk cost bias

The sunk cost bias occurs when individuals continue to invest in the same option when better alternatives are available. Many researchers believe that this bias is due to overemphasizing the past investment over the (missed) opportunities offered by alternatives. As an alternative or complement to this view, we show that memory retrieval and attention play important roles in the sunk cost bias. In two experiments, individuals generated more reasons for pursuing the invested option than for an alternative; they generated those reasons earlier in a sequence of reasons; and these effects increased as the individuals made progress toward attaining the reward yielded by the invested option. Associated with these effects, individuals perceived an increasingly wide gap in value between the invested and alternative options as they progressed toward the goal, thereby creating the sunk cost bias. Forcing individuals to reverse the order in which they generated reasons for the invested and alternative options reduced the bias. [corrected]
