Does prism adaptation affect visual search in spatial neglect patients: A systematic review

Prism adaptation (PA) is a widely used intervention for (visuo‐)spatial neglect. PA‐induced improvements can be assessed by visual search tasks. It remains unclear which outcome measures are the most sensitive for the effects of PA in neglect. In this review, we aimed to evaluate PA effects on visual search measures. A systematic literature search was completed regarding PA intervention studies focusing on patients with neglect using visual search tasks. Information about study content and effectiveness was extracted. Out of 403 identified studies, 30 met the inclusion criteria. The quality of the studies was evaluated: Rankings were moderate‐to‐high for 7, and low for 23 studies. As feature search was only performed by five studies, low‐to‐moderate ranking, we were limited in drawing firm conclusions about the PA effect on feature search. All moderate‐to‐high‐ranking studies investigated cancellation by measuring only omissions or hits. These studies found an overall improvement after PA. Measuring perseverations and total task duration provides more specific information about visual search. The two (low ranking) studies that measured this found an improvement after PA on perseverations and duration (while accuracy improved for one study and remained the same for the other). This review suggests there is an overall effect of PA on visual search, although complex visual search tasks and specific visual search measures are lacking. Suggestions for search measures that give insight in subcomponents of visual search are provided for future studies, such as perseverations, search path intersections, search consistency and using a speed–accuracy trade‐off.     

Effect of achievement motivation on cognitive control adaptations

Previous research addressing motivational effects on cognitive control adaptations primarily manipulated external rewards. In the present study, we examined whether achievement motivation, reflecting intrinsic motivation, modulates cognitive control adaptations. In each of two experiments, students were divided into a high achievement motivation group (HAM; Experiment 1: N?=?36; Experiment 2: N?=?39) and a low achievement motivation group (LAM; Experiment 1: N?=?30; Experiment 2: N?=?39) on the basis of the Achievement Motivation Scale. Cognitive control adaptations were assessed by sequential congruency effects (SCEs) in Flanker tasks. Using a standard Flanker task in Experiment 1 and examining response times, the HAM but not LAM participants showed evidence of cognitive control adaptations. Because SCEs in a standard Flanker task may reflect lower-level, bottom-up processes rather than cognitive control adaptations, we used an adapted version of the Flanker task in Experiment 2 that controlled for the potential influence of such processes. Experiment 2 again revealed evidence of SCEs in the HAM but not LAM participants. These results suggest that cognitive control adaptions may be modulated by achievement motivation. Such potential modulation could be taken into account when evaluating results of previous and future fundamental and applied studies on cognitive control adaptations.     

适应范式在人脸知觉研究中的应用

适应范式为考察各种心理现象或心理过程的机制提供了一条重要的途径。本文在简要介绍传统适应范式和功能性磁共振适应范式的基础上,重点回顾了它们在人脸知觉研究中的应用,提出人脸适应后效除源于尺寸和朝向等低、中水平物理信息的编码加工外,更多地基于身份和性别等高水平社会信息的编码,且其效应量依赖于高水平的基于标准的竞争性编码加工机制。对人脸类别属性的编码标准和时效性等问题仍有待进一步分析。     

Immediate and long-term priming effects are independent of prime awareness

Subliminal primes are assumed to produce weaker and short-lived effects on subsequent behavior compared to clearly visible primes. However, this difference in priming effect may be due to differences in signal strength, rather than level of awareness. In the present study we manipulated prime discriminability by using metacontrast masks and pseudomasks, while keeping the prime strength equal. This manipulation resulted in large differences in discriminability of the primes. However, both immediate response priming and long-term response priming (measured with conflict adaptation) was equal for the poorly discriminable and well discriminable primes, and equal for groups that differed markedly in terms of how well they could discriminate the primes. Our findings imply that discriminability of information is independent of both the immediate and long-term effects that information can have on behavior.     

不公平感及相关决策的认知神经机制

公平是人类社会生活的基本规范之一,不公平感及其相关决策则是研究者们关注的重要课题。长期以来,该领域的研究一般采用最后通牒博弈或其变式展开。大量脑成像研究探查了关于不公平感及相关决策的认知神经机制,尤其集中探讨了最后通牒博弈的回应者对不公平提议进行反应的脑区及其对应功能。经常得到关注的脑区包括了前脑岛、前扣带皮层、背外侧前额叶、内侧前额叶、杏仁核和颞顶交界等。对特殊人群的不公平感及相关决策进行研究可以帮助检验或澄清上述重要脑区及脑网络在不公平感及相关决策中扮演的角色,同时也阐释特殊人群的社会认知功能的特点。近年来,相当数量的研究关注了不同情境因素(包括分配方案相关因素和社会情境相关因素)调制不公平感及相关决策的过程,并讨论其背后的认知神经机制。未来的研究更应利用多模态数据分析方法,同时结合基因和激素层面的研究,以期深入对不公平感及相关决策的心理和生理机制的理解。     

青年员工职业适应压力源探析

对浙江省某市20家企业146名青年员工的职业适应压力现状进行调查。结果显示:(1)职业适应问题确实给青年员工带来职业适应压力,其中适应突发事件压力和职业前途压力较大;(2)不同性别、学历、婚姻状况和企业类型的青年员工在职业适应压力的一些维度上差异显著;(3)逐步回归结果表明身体适应压力和人际适应压力对总压力体验有显著影响,身体适应压力、动态任务完成及创新压力对心理体验有显著影响,身体适应压力对情绪体验和生理体验有显著影响。     

DO PEOPLE REALLY ADAPT TO MARRIAGE?

Although cross-sectional studies have shown a reliable association between marital status and subjective well-being, a recent longitudinal study [Lucas et al. 2003, Journal of Personality & Social Psychology 84(3), pp.␣527–539] found no support for the idea that happiness increases after marriage. Instead, participants who got married reported short-term increases followed by complete adaptation back to baseline levels of well-being. However, researchers have criticized this study on two grounds. First, these results contradict cohort-based analyses from a nationally representative sample. Second, these analyses do not control for pre-marriage cohabitation, which could potentially inflate baseline levels of well-being. The original data (plus four additional waves) are reanalyzed to address these concerns. Results confirm that individuals do not get a lasting boost in life satisfaction following marriage.The data used in this paper were made available by the German Institute for Economic Research (DIW). This research was supported by a grant from the Anthony Marchionne Foundation.     

父母支持与服刑青少年的情绪适应:公正世界信念的中介作用

以446名服刑青少年为被试,采用问卷法,探讨了青少年服刑后的父母支持、公正世界信念与其情绪适应的关系及作用机制。结果表明:(1)服刑青少年的情绪适应状况较差,抑郁水平较高,生活满意度较低;(2)服刑后的父母支持和公正世界信念显著负向地预测青少年的抑郁,显著正向地预测其生活满意度;(3)公正世界信念在父母支持和抑郁、生活满意度之间均起着部分中介作用。这表明,服刑后青少年的父母支持既可以直接促进其服刑期间的情绪适应,又可以通过提升其公正世界信念来促进其服刑期间的情绪适应。     

儿童资源获取行为对学校适应的影响——一个历时5年的跨文化追踪

以160名中国儿童和133名加拿大儿童为被试,采用实验室观察和问卷调查,考察儿童7岁时的资源获取行为对其11岁时学校适应的影响。结果表明：（1）轮流规则行为对儿童的学校适应具有消极的预测作用,且存在性别差异：男孩的轮流规则行为可以显著正向预测其焦虑,女孩的轮流规则行为可以显著负向预测其学校态度;（2）请求行为可以显著正向预测中国儿童攻击行为,加拿大儿童则没有发现该关系;（3）对于资源获取失败次数少的儿童,求助成人行为有积极的适应意义;（4）儿童资源获取行为的结果在儿童7岁时资源获取行为与11岁时学校适应之间发挥调节作用;对于资源获取成功次数少的儿童,请求行为可以显著地正向预测其攻击行为;对于资源获取失败次数少的儿童,请求行为则显著地负向预测其攻击行为,求助成人行为可以显著地负向预测其孤独感。
