无边界职涯背景下的离职:重回决策者中心

离职曾被视作组织中的"问题"而受到学术界的重视。传统离职研究更关注通过改变员工的态度来减少离职,进而降低离职对组织产生的负面影响,具有鲜明的组织立场。然而离职的本质是员工个体的决策。无边界职业生涯背景下,面对更加多样化的生涯选择,员工在离职决策中的主体性更加凸显,离职研究需要重回决策者中心,重新聚焦决策者:(1)以决策者为中心探讨离职影响因素;(2)探讨决策者制定离职决策的内在过程;(3)关注员工离职的实际行为及后果。     

Area activation: a computational model of saccadic selectivity in visual search

The Area Activation Model (Pomplun, Reingold, Shen, & Williams, 2000) is a computational model predicting the statistical distribution of saccadic endpoints in visual search tasks. Its basic assumption is that saccades in visual search tend to foveate display areas that provide a maximum amount of task‐relevant information for processing during the subsequent fixation. In the present study, a counterintuitive prediction by the model is empirically tested, namely that saccadic selectivity towards stimulus features depends on the spatial arrangement of search items. We find good correspondence between simulated and empirically observed selectivity patterns, providing strong support for the Area Activation Model.     

任务转换条件下对特征的并行搜索

采用双任务范式,以两个实验探讨了任务设置与刺激特征的匹配程度对特征搜索方式的影响。要求被试首先辨认数字序列中包含的字母,随后完成特征搜索任务。在实验一中特征搜索任务是检测同时呈现的多个灰色圆点(干扰子）中是否有红色圆点(目标）出现。在实验二中,以多种不同颜色的圆点代替实验一中的灰色干扰子。结果发现：在特征搜索主要由自下而上的信息或自上而下的信息引导的两种条件下,任务设置与刺激特征的匹配程度均不影响特征搜索方式,特征搜索仍以并行方式进行。据上述结果笔者推测,在任务设置与刺激特征不匹配的条件下,视觉加工系统首先调整任务设置使二者相匹配,随后进行高效率的并行搜索,而非在二者不匹配的条件下进行低效率的系列搜索。     

A threat-detection advantage in those with autism spectrum disorders

Identifying threatening expressions is a significant social perceptual skill. Individuals with autism spectrum disorders (ASD) are impaired in social interaction, show deficits in face and emotion processing, show amygdala abnormalities and display a disadvantage in the perception of social threat. According to the anger superiority hypothesis, angry faces capture attention faster than happy faces in individuals with a history of typical development [Hansen, C. H., & Hansen, R. D. (1988). Finding the face in the crowd: An anger superiority effect. Journal of Personality and Social Psychology, 54(6), 917–924]. We tested threat detection abilities in ASD using a facial visual search paradigm. Participants were asked to detect an angry or happy face image in an array of distracter faces. A threat-detection advantage was apparent in both groups: participants showed faster and more accurate detection of threatening over friendly faces. Participants with ASD showed similar reaction time, but decreased overall accuracy compared to controls. This provides evidence for less robust, but intact or learned implicit processing of basic emotions in ASD.     

相似性信息的激活对情境性表征影响的年龄差异

使用视觉搜索范式研究了6岁、9岁、12岁和成人,在限时和不限时呈现材料条件下对实物图形的视觉搜索及再认。结果表明:1)限时和不限时视觉搜索任务方式对视觉搜索和再认的准确性、反应时均有显著影响。2)视觉搜索和再认的准确性随被试年龄的增长而提高,反应时则随其年龄增长而缩短。3)靶项目是否作为搜索项目出现对视觉搜索和再认的准确性没有显著影响,但对视觉搜索和再认的反应时有显著影响,靶项目的出现使视觉搜索和再认的反应时都显著缩短。4)搜索项性质对视觉搜索和再认的反应时指标有显著影响,但对准确性没有显著影响。     

视觉搜索中多目标追踪的研究

在视觉信息的选择加工过程中 ,只有很少信息能够通过注意系统得到进一步的认知加工 ,其中视觉搜索起着十分重要的作用。本研究基于动态视觉信息注意追踪的研究 ,采用 3× 2× 2的实验设计 ,从如下三方面对注意追踪的规律进行了探讨 :(1)分心物数量 (1,5和 9)的变化对多目标注意追踪的影响 ;(2 )目标的显著性 (特征变化和特征不变 )对多目标注意追踪的影响 ;(3)目标运动形式 (目标随机运动和目标运动形式不变 )对多目标注意追踪的影响。研究结果表明 :(1)分心物数量的增加对目标的注意识别没有抑制作用 ;(2 )特征变化目标的注意识别速度显著高于特征不变的目标 ;(3)运动形式不变的目标较运动形式变化目标的注意识别速度快。     

Le TASC200, une épreuve d’attention et de saillance visuelle : fidélité, validité et normes préliminaires

In the clinical setting, attention is classically assessed by tasks that do not take into account theoretically important aspects, such as the salience-based guidance of visual search. The aim of this study was to develop a paced paper-and-pencil task for clinical use based on strong theoretical accounts that would assess salience-based visual search and that would meet the psychometric requirements for the assessment of attention. Participants were required to search and cancel targets of varying visual saliences as quickly and as accurately as possible during a predefined short period of time. The targets were intermixed with distractors. In agreement with theories of salience-based visual search, the results showed that the most salient targets were detected more easily than less salient targets. The task exhibited a quite acceptable test-retest reliability, and two construct validity studies showed that different scores involve different processes. This new task fully complies with the major theories of salience-based guidance of attention during visual search. It also meets the requirements of a plausible clinical task since its psychometric qualities are quite good. Preliminary normative data (n = 863) are presented for clinical use.     

Expecting the initial glimpse: prior target knowledge activation or repeated search does not eliminate scene preview search benefits

A brief glimpse of a scene can guide eye movements but it remains unclear how prior target knowledge influences early scene processing. Using the ‘flash-preview moving window’ (FPMW) paradigm to restrict peripheral vision during search, we manipulated whether target identity was presented before or after previews. Windowed search was more efficient following 250?ms scene previews, and knowing target identity beforehand further improved how search was initiated and executed. However, in Experiment 2 when targets were removed from scene previews, only the initiation of search continued to be modulated by prior activation of target knowledge. Experiment 3 showed that search benefits from scene previews are maintained even when repeatedly searching through the same type of scene for the same type of target. Experiment 4 replicated Experiment 3 whilst also controlling for differences in integration times. We discuss the flexibility of the FPMW paradigm to measure how the first glimpse affects search.     

聋人大学生心理控制源对求职行为的影响：职业成熟度的中介作用

采用中国大学生控制源测量问卷、职业成熟度量表和高校应届毕业生求职调查问卷对重庆、北京、吉林、天津4地4所高校的386名聋人大学生进行调查,旨在探讨聋人大学生心理控制源、职业成熟度与求职行为的关系,揭示职业成熟度在心理控制源与求职行为之间的中介作用机制。结果发现：（1）内控对职业成熟度和求职行为均具有显著的正向预测作用。（2）职业成熟度在内控与求职行为之间起部分中介作用。（3）职业成熟度在外控对求职行为的影响中起着“遮掩效应”。     

真实物体搜索中的视角依赖效应:来自眼动的证据

已有研究发现物体识别存在视角依赖效应,那么在真实物体搜索中是否也存在视角依赖效应呢?本研究采用物体阵列搜索任务,通过眼动技术探讨真实物体搜索中的视角依赖效应及其来源。结果发现:(1)图片提示的搜索绩效优于名称提示;(2)以名称提示时,常规视角的搜索绩效高于新异视角,与新异视角相比,以常规视角呈现的目标物体在扫描和确认阶段的注视点数较少且持续时间较短,表现出视角依赖效应;(3)以图片为提示时,搜索绩效与视角无关。由此可见,在以名称提示的物体搜索中,常规视角比新异视角条件下的注意引导更高效,对目标物体的确认也更快,扫描和确认阶段均存在视角依赖效应,支持目标模板的双功能理论。
