语义关联性对重复知盲效应的影响：来自汉语成语的证据

重复知盲是在快速系列视觉呈现任务中对第二个重复刺激的加工缺陷。以汉语中反义字和成语为实验材料,采用全部报告任务,探讨刺激的语义关联性对重复知盲的影响。实验1以汉语单字为材料,采用单因素三水平（目标刺激之间的语义关系：无关、相同、相反）被试内设计,结果是重复字产生重复知盲效应,反义字产生语义启动效应。实验2以成语为材料,采用2（目标刺激之间的语义关系：相同、无关）×2（位置：前位置、后位置）设计,结果是语义关联性消解了重复知盲效应。结果表明：（1）反义字不产生重复知盲效应。（2）语义关联性消解成语中重复字的重复知盲效应。（3）实验结果支持竞争假设。     

语音控制加工经验有助于促进语音执行控制功能

来自双语的研究表明,双语者在抑制、转换、注意力维持等执行控制功能方面较之于单语者具有显著的认知优势效应。该效应是双语者对诸多语言亚成分协同控制的结果,还是对不同语音体系控制的结果,目前依然存在争论。本研究以单语单言儿童（仅会说汉语普通话）和单语双言儿童（同时会使用汉语普通话和泰州方言）为被试,通过线索-切换任务和语音Stroop任务就上述问题进行了研究。结果显示：（1）在线索-切换任务上,两组儿童作业表现差异不显著;（2）在语音Stroop任务上,单语双言儿童具有显著的认知优势。据此,本研究认为双语认知优势的获得是个体对诸如句法、语义、正字法、语音、词素等多种语言亚成分协同控制的结果。     

人类精子冷冻保存的回顾与思考

回顾人类精子冷冻保存方法的历史,分别比较分析精液保存的常规冷冻法、玻璃化冷冻法和冷冻干燥保存法的特点和前景。认为人类精子冷冻保存方法是低温生物学与辅助生殖技术相互发展和基础理论研究与临床应用相互作用的结果,简便可靠的冷冻保存方法仍需进一步研究。     

It’s security,stupid! Voters’ perceptions of immigrants as a security risk predicted support for Donald Trump in the 2016 US presidential election

We analyzed two datasets to determine the predictive validity of four explanations of support for Donald Trump during the 2016 US presidential election: (a) security concerns regarding immigrants, (b) economic concerns regarding immigrants, (c) cultural concerns regarding immigrants, and (d) social dominance orientation. Results of a two‐phase study (N = 354) suggested that perceiving immigrants as a security concern was predictive of increased support for and greater odds of voting for Donald Trump three weeks later. Perceiving immigrants as an economic threat predicted odds of voting for Donald Trump, but only among liberals and there was no evidence of cultural concern or social dominance orientation (SDO) predicting support for Donald Trump or odds of voting for Trump. A follow‐up analysis of the cross‐sectional ANES survey corroborated that security concerns were an important correlate of voting for Trump, but also that SDO was correlated with having previously voted for Donald Trump. While our two‐phase study has the benefit of prediction, the cross‐sectional ANES data does not—“predictors” in these data were collected up to two months post‐election.     

Competitively Contingent Rewards and Intrinsic Motivation: Can Losers Remain Motivated?

We explored the effects on intrinsic motivation and ego-involved persistence of winning versus losing a competitively contingent reward and, for losers, the additional effects of receiving either positive performance feedback or performance-contingent rewards. Winners were more intrinsically motivated than losers. Losers given an explicit normative standard who received positive feedback for meeting the standard were more intrinsically motivated than losers who did not receive the additional standard and feedback. Losers who received a performance-contingent reward for reaching the same explicit standard displayed less intrinsic motivation behaviorally assessed than did losers who got positive feedback, but the two groups did not differ on self-reported enjoyment. Effects on enjoyment were mediated by perceived competence, but effects on free-choice behavior were not. People who lost the competition showed more ego-involved persistence than people who won or did not compete.     

Sex Differences in Competitive and Compliant Unethical Work Behavior

Male and female librarians were compared in terms of their willingness to engage in competitive unethical work behavior and on their willingness to comply with organizational pressures to behave unethically. Men report a greater willingness to engage in each of these behaviors. Results are discussed in terms of sex differences in personality characteristics.     

内部竞争环境下内群体偏好的维持:群体认同和心理距离的影响

内群体偏好对群体及个人的生存发展都有重要价值。研究通过三个实验揭示了个体在内部竞争下维持内群体偏好的机制。实验一操纵内部竞争(有,无)和群体认同(高,低),发现内部竞争破坏了内群体偏好,而群体认同无法改变此破坏作用。实验二操纵内部竞争(有,无)和内群体心理距离(远、近),发现内部竞争破坏内群体偏好时,心理距离能够调节二者的关系,近心理距离有益于个体在内部竞争下维持内群体偏好。实验三进一步分析了心理距离维持内群体偏好的作用机制,发现心理距离通过个体知觉到的内部竞争感而影响内群体偏好。据此可认为,在内部竞争中维持内群体偏好需更多地关注成员间的关系(缩短心理距离),而非单纯地强调个体和群体间的联结(群体认同)。     

Negative emotion words are less susceptible to repetition blindness

Repeated and orthographically similar words are vulnerable in RSVP, as observed using the repetition blindness (RB) paradigm. Prior researchers have claimed that RB is increased for emotion words, but the mechanism for this was unclear. We argued that RB should be reduced for words with properties that capture attention, such as emotion words. Employing orthographic repetition blindness, our data showed that words with negative emotional valence had a report advantage when they were the second of two similar words (e.g., less RB occurred with HORSE curse than with HORSE purse). This renders emotion RB similar to the use of emotion words in the attentional blink phenomenon. The findings demonstrate the neglected role of competition in conscious recognition of multiple words under conditions of brief display and masking.     

Adaptation in conflict: are conflict-triggered control adjustments protected in the presence of motivational distractors?

Solving a conflict between two response options in an interference task has been found to increase control in a subsequent conflict situation. The present research examined whether such conflict adaptation persists in the presence of distractors that have motivational relevance and are therefore competing for attentional resources (i.e. they signal opportunities for monetary gains or losses contingent on overall task performance). In an adjusted flanker task, motivational (versus neutral versus no) distractors were presented together with the current trial while the previous trial never included any distractor. Accumulated evidence across three studies showed that motivational distractors reduced the conflict adaptation effect. This was found irrespective of the location at which the distractor occurred (Study 1), and independent of its valence (i.e. reward or loss, Study 2). Study 3 and a merged data analysis ruled out low-level alternative explanations. In line with a dual competition account (Pessoa, L. (2009). How do emotion and motivation direct executive control? Trends in Cognitive Sciences, 13(4), 160–166. doi:10.1016/j.tics.2009.01.006), our results show that conflict adaptation is not fully protected in the presence of motivational distractors. We discuss whether this should be interpreted as a limitation, or as reflecting the flexibility of the control system in dealing with motivationally relevant information.
