Mapping the color space of saccadic selectivity in visual search

Color coding is used to guide attention in computer displays for such critical tasks as baggage screening or air traffic control. It has been shown that a display object attracts more attention if its color is more similar to the color for which one is searching. However, what does similar precisely mean? Can we predict the amount of attention that a display color will receive during a search for a given target color? To tackle this question, two color‐search experiments measuring the selectivity of saccadic eye movements and mapping out its underlying color space were conducted. A variety of mathematical models, predicting saccadic selectivity for given target and display colors, were devised and evaluated. The results suggest that applying a Gaussian function to a weighted Euclidean distance in a slightly modified HSI color space is the best predictor of saccadic selectivity in the chosen paradigm. Hue and intensity information by itself provides a basis for useful predictors, spanning a possibly spherical color space of saccadic selectivity. Although the current models cannot predict saccadic selectivity values for a wide variety of visual search tasks, they reveal some characteristics of color search that are of both theoretical and applied interest, such as for the design of human–computer interfaces.     

为构建和谐社会作贡献 为加强自身建设多努力——在中国道教协会第七次全国代表会议上的讲话

各位代表、各位朋友:今天,大家欢聚北京,隆重举行中国道教协会第七次全国代表会议。会议将总结过去六年多来的工作,选举产生新一届领导班子,研究部署今后五年的工作,特别就如何发挥道教优良传统为构建社会主义和谐社会作贡献问题进行深入讨论。这次会议的召开,是中国道教界的一     

风险对两类跨期选择的影响：一项ERP研究

该研究利用ERP技术,采用伴随风险的跨期选择任务比较了两类跨期选择（立即vs.延迟、延迟vs.延迟）,并探究了风险（零风险、低风险、高风险）对两者跨期选择影响的神经动力学机制。ERP结果显示,对于立即vs.延迟和延迟vs.延迟,在N2和N400上前者大于后者,在LPC上后者大于前者;风险对两者在时程上的影响趋于一致。因此,其加工可能是先对奖赏在风险维度上进行折扣,再与延迟时间进行整合形成奖赏预期,而后做出选择。     

一般心理能力(GMA)预测绩效:现状、机制及趋势

一般心理能力(General Mental Ability,GMA)是人事选拔领域应用最为普遍的预测源,百年来的研究证实,GMA不仅直接影响工作知识的获得与技能习得,还通过学习和问题解决间接影响个体的工作绩效,是工作绩效的最佳预测源。未来对GMA本质以及GMA与绩效关系的探讨,除了经典测量学视角外,还应借鉴认知神经研究范式,深入揭示GMA预测工作绩效的脑认知机制,同时进一步收集GMA的预测效度以及中国情境下的概化效度证据。     

Career-specific parental behaviors,career exploration and career adaptability: A three-wave investigation among Chinese undergraduates

The current research examined the effects of career-specific parental behaviors (reported by parents at time 1) on Chinese university students' career exploration (reported by students at time 2) and career adaptability (reported by students at time 3). A survey study was conducted among Chinese university graduates (N = 244) and their parents (N = 244). The results supported a mediation model such that a high level of parental support and a low level of parental interference had beneficial effects on Chinese undergraduates' career exploration, which in turn positively predicted their career adaptability. Lack of parental career engagement had a direct negative effect on career adaptability. Significant interaction effects were also found among these three types of parental behaviors such that at a lower level of lack of parental career engagement, the positive effects of parental support, as well as the negative effects of interference on career exploration were stronger. The corresponding moderated mediation models were also supported. These findings carry implications for research on career construction theory and career counseling practices.     

男性对女性面孔吸引力的认知偏好: 来自ERP的证据

运用事件相关电位(ERPs)技术, 采用学习-再认实验任务, 探讨了男性对有、无吸引力女性面孔图片进行判断和再认时脑内时程的动态变化。行为数据结果表明, 男性对有吸引力女性面孔的反应时更长, 再认正确率更高。ERP结果发现, 有、无吸引力面孔诱发的ERP早成分和晚成分都存在显著差异, 最强效应出现在大脑皮层的中前部。在判断任务和再认任务中, 有吸引力的女性面孔都比无吸引力的女性面孔诱发出更大的ERP成分(分别为N300、P350~550ms和P160、N300~500ms、P500~700ms)。结果表明, 男性对有吸引力的女性面孔的判断和再认存在偏好。     

选择、自我表达与选择扩散效应

自我表达会影响西方人的态度, 产生选择扩散效应。国外相关的跨文化研究发现东方人不存在该效应。通过4个实验研究中国文化下自我表达对选择态度的影响, 发现选择方式(主动、被动)和自我表达形式(直接、间接)对选择态度产生影响。无论是自己的主动选择还是强加的被动选择, 直接的自我表达会增加对所获对象的喜爱程度, 表现为对获得性的肯定。研究者认为, 两种选择方式下不同的心理加工过程导致了这种获得性：直接表达使个人态度暴露在外, 进行主动选择时要对他人的给予做出肯定回应; 而进行被动选择时, 人们要减缓因利益受损可能导致的失调, 同时中国文化下的面子策略也使人们增加对所获对象的喜爱程度。不过, 间接的自我表达对选择态度的影响不明显。研究者认为, 多个影响因素的相互消长使选择态度得以维持。     

关系因素与个体因素在儿童早期社会能力中的作用

采用儿童早期行为评价量表、亲子关系量表和师生关系量表,对443名幼儿的父母和教师进行了测查,在生态系统理论的框架下探讨了儿童性别、年级及父子、母子、师生关系对早期社会能力的影响。结果发现:小班和中班儿童的师生关系好于托班;女孩的社会能力高于男孩,小班和中班儿童的社会能力高于托班。控制了性别与年级的作用之后,父子、母子与师生关系对儿童社会能力都有显著的正向预测作用,但三者的平均值具有最强的预测作用,这一结果支持了多重关系作用于儿童发展的"平均化假说"。     

表象测量方法述评

表象测量在训练领域广泛应用,也是训练成败的关键环节.表象测量方法可分为口头报告纸笔法、实验操作法,以及神经科学技术共三种方法.其中纸笔报告法以量表测量为主,包括Betts量表、视觉表象清晰度量表及其修订版和运动表象清晰度量表及其修订版;实验操作法以心理旋转为基本范式;神经科学技术主要以经颅磁刺激和功能磁共振成像为主,测量多种表象过程中不同脑区兴奋性.三者各有优劣,均有待提高和改进.
