What happens in a psychoanalysis?

A group of experienced analysts has developed scales and a coding manual illustrated with clinical examples to evaluate recorded analyses and psychodynamic therapies. The analytic process scales (APS) assesses three dimensions: (1) the contribution of the analyst: helping to develop a relationship in which the analyst can provide clarification and interpretation of transference and resistance; (2) the contribution of the patient: the communication of experience and the expression of feeling in ways which provide information about needs, wishes and conflicts, accompanied by self-reflection; and (3) interactional characteristics of the emerging relationship, explored by studying sessions divided into psychoanalytically coherent segments. A preliminary study of nine sessions has established that the variables assessed by the APS can be rated reliably. Study of the analysts' contributions illuminated their varied and complexstructure. Important differences emerged among the three patient-analyst pairs studied, and changes in scores over time tracked developments in the analytic work which would imply different treatment outcomes. The APS appears to be a reliable tool facilitating the systematic study of psychoanalyses.     

Stopping rule use during information search in design problems

Information search is critical in most decision-making tasks. An important aspect of information search is the stopping rule used by the decision maker to terminate information acquisition. Decision-making problems may be usefully decomposed into design problems and choice problems. The distinction is critical because the goals of stopping behavior in the two types of problems are quite different. In design problems, the focus is on the sufficiency of information obtained for problem structuring and generating alternatives, while choice problems focus on convergence toward a solution. While previous research has studied stopping behavior in choice problems, the present research is concerned with stopping rule use during information search in design problems. To build theory in this area, we conducted two experiments. In the first, we presented professional systems analysts with an information search problem in a systems development context and asked them to gather information for a proposed system. Protocols of the search sessions were analyzed, and stopping rules used and information gathered by the analysts were identified. Results indicated that the use of certain stopping rules resulted in greater quantity and quality of information gathered. Additionally, stopping rule use, rather than analyst experience, accounted for the quantity and quality of information elicited. Finally, stopping rule use differed between more experienced and less experienced analysts. To apply our findings about stopping rules from the first experiment, we performed a second experiment in which we investigated stopping rule use in a consumer information search task on the world wide web. Results indicated the use of the same stopping rules as in the first experiment, although in different proportions. Implications for information search theory and practice are discussed.     

关于人工语法学习迁移效应的一项实验研究

本研究探讨了人工语法迁移效应产生的机制,着重考查了组块信息迁移理论对人工语法迁移效应机制解释的适宜性。结果发现：当学习和测验序列的表层结构不同时,被试能够学习和迁移非重复成分间的序列依存性(实验一);当被试将非重复成分间的序列依存性迁移到表层结构不同的测验序列中时,需要在学习和测验序列的分布特征上形成一种匹配(实验二)。     

背景线索对室内场景中目标搜索的注意引导

以室内3D场景图为实验材料,采用眼动追踪技术,探讨背景线索对真实场景视觉搜索过程中的注意引导。结果发现：在室内场景目标搜索过程中存在背景线索效应,该效应基于对背景-目标共变关系的外显记忆;背景线索对搜索的启动和确认阶段无影响,对扫描阶段的注视行为有促进作用,有助于更有效地选择注视区域,将注视更直接地导向目标所在位置。     

Walk this way: approaching bodies can influence the processing of faces

A highly familiar type of movement occurs whenever a person walks towards you. In the present study, we investigated whether this type of motion has an effect on face processing. We took a range of different 3D head models and placed them on a single, identical 3D body model. The resulting figures were animated to approach the observer. In a first series of experiments, we used a sequential matching task to investigate how the motion of an approaching person affects immediate responses to faces. We compared observers’ responses following approach sequences to their performance with figures walking backwards (receding motion) or remaining still. Observers were significantly faster in responding to a target face that followed an approach sequence, compared to both receding and static primes. In a second series of experiments, we investigated long-term effects of motion using a delayed visual search paradigm. After studying moving or static avatars, observers searched for target faces in static arrays of varying set sizes. Again, observers were faster at responding to faces that had been learned in the context of an approach sequence. Together these results suggest that the context of a moving body influences face processing, and support the hypothesis that our visual system has mechanisms that aid the encoding of behaviourally-relevant and familiar dynamic events.     

颜色知觉突显对预览效益的影响

本研究通过预览搜索范式考察靶子在颜色高突显情况下的预览效益,探讨其优先选择机制。结果发现在靶子颜色高突显的情况下,预览效益没有出现,说明预览效益的出现有其一定的条件和限制,并为基于刺激特征的抑制的解释提供了支持证据。本文还探讨了预览效益消退的可能原因。     

视觉选择过程中眼跳与注意关系的理论进展

视觉选择的过程包含两种途径:眼跳行动和注意转移,两者对于视觉选择目标物的加工都有促进作用。鉴于此,视觉研究领域产生大量关于二者关联如何的实验研究,大部分研究者认为眼跳和注意转移存在密切联系。该文将关于两者关系的重要理论进行了综合阐述和简要比较,主要介绍五种理论假说:眼动准备假说、动前假说、顺序注意模型、视觉注意模型和竞争整合模型。     

不同位置的情绪面孔加工对返回抑制的影响

分别将情绪面孔图片作为线索（实验一）或靶子（实验二）呈现,利用线索-靶子范式考察了定位任务中情绪面孔加工对返回抑制的影响。结果发现：以不同情绪面孔作为线索时,返回抑制稳定出现,表现出与情绪加工的分离;而当情绪面孔作为靶子时,与中性面孔相比,情绪面孔引发的返回抑制量显著较小。该研究表明,在定位任务中,返回抑制不受线索生物性的影响,但是会受到靶子性质的影响,反映出机体在不同条件下对空间注意和情绪加工的灵活性。     

奖赏预期调节局部注意干扰效应

局部注意干扰效应(Localized attentional interference, LAI)是指在视觉搜索任务中同时搜索在空间上分离的两个目标时, 或者目标周围存在一个无关奇异项时, 这两个关键刺激相距较近时产生的干扰现象。本实验采用视觉搜索范式, 探讨了奖赏预期对局部注意干扰效应的影响。实验1采用双目标搜索任务, 要求被试判断搜索画面中两个奇异项刺激的形状是否相同。结果显示奖赏条件和无奖赏条件都表现出显著的距离主效应, 随着目标间距离增大, 被试的正确率提高, 反应时下降。同时, 在远距离时, 奖赏条件下的正确率高于无奖赏条件, 而在近距离时, 奖赏条件下的正确率反而低于无奖赏条件, 即, 奖赏条件下局部注意干扰效应反而增大。高动机状态增强了两个目标的表征, 反而不利于解决局部注意干扰效应。实验2采用单目标搜索任务, 要求被试判断特定目标的方位并忽略另一无关奇异项刺激。与实验1不同的是, 实验2仅在无奖赏条件下观察到显著的距离主效应, 即被试行为表现在远距离时更好; 而在奖赏条件下, 被试在近距离和远距离的表现一样好, 即没有局部注意干扰效应。这说明在奖赏预期条件, 个体可以有效抑制分心物刺激的干扰, 将注意集中于目标刺激的加工, 从而对局部注意干扰效应产生调节。整个研究表明, 奖赏整体上能够提高对任务相关刺激的表征, 并抑制任务无关刺激, 虽然这并不总是能够提高任务表现。     

大学新生的人生意义与抑郁:交互效应与中介效应

基于Frankl(1963)的意义疗法理论观点和Steger等(2006)提出的人生意义双维构念, 考察人生意义对大学新生抑郁的影响机制, 分析其中可能存在的交互效应和中介效应。采用问卷法调查了某东部省会城市1所理工科大学、1所综合性大学的435名新生, 结果表明:(1)大学新生的意义体验与无聊倾向、抑郁负相关, 与希望正相关;意义寻求与意义体验、抑郁的相关均不显著;(2)意义体验和意义寻求对抑郁具有交互效应, 对意义寻求较低的个体, 意义体验的保护作用更强;(3)意义体验通过无聊倾向和希望的并行多重中介效应影响抑郁, 且无聊倾向的中介效应显著强于希望。
