负数的空间表征引起的空间注意转移

本研究采用数字线索提示的刺激探测任务, 通过三个实验探讨负数的低水平加工能否,以及怎样引起空间注意的转移。实验一探讨只有负数单独呈现作为线索时能否引起空间注意的转移。结果表明：对负数绝对值大小的加工能引起空间注意的转移。实验二进一步探讨在正数、负数和零混合作为线索时能否引起空间注意的转移。结果表明：对负数数量大小的加工能引起空间注意的转移。实验三再次用正数, 负数和0三种数字混合作为探测刺激前的线索, 但仅对负数和零作为提示线索之后的探测刺激进行反应, 又一次得到了由有效提示线索所引发的对数字数量大小加工引起的空间注意的转移。本研究表明, 对负数的低水平加工可以引起空间注意的转移, 然而, 是对绝对值的加工还是数量大小的加工引起注意转移依赖于共同参与的其它数字加工产生的影响。     

文本阅读中时间信息加工的二阶段模型

运用动窗与眼动技术考察文本阅读中时间信息的加工特点符合强印象假设还是场景理论。行为实验结果发现, 关键句和时间词的阅读时间以及探测词的反应时符合强印象假设, 而关键事件的阅读时间和对问题的反应时符合场景理论。眼动实验结果发现, 在时间词区, 总阅读时间、总阅读次数符合场景理论; 对于关键事件, 总阅读时间、回视路径时间和总注视点次数也符合场景理论; 在时间词区以及关键事件上反应早期阶段加工的首次注视时间上不同条件没有显著的差异, 但总体趋势符合强印象假设。据此, 本研究提出的时间信息加工的二阶段模型得到初步证明。     

内源性眼跳与注意转移关系研究述评

视觉选择过程中既存在外显的眼跳行为,也包含内隐的注意转移,两者对于视觉目标的加工都有促进作用。近二十年来出现大量关于二者关系的研究,多数研究者发现眼跳和注意转移存在密切联系。内源性眼跳是个体根据目标或意愿主动发起的眼跳,对人类生存具有重大意义。本文系统回顾了视觉加工领域中对于内源性眼跳与空间注意转移关系问题的探讨及其研究成果,分别从行为研究和神经心理学研究两个方面阐述了该领域的研究进展并作出简要评价及展望。     

Goal saliency boosts infants’ action prediction for human manual actions,but not for mechanical claws

Previous research indicates that infants’ prediction of the goals of observed actions is influenced by own experience with the type of agent performing the action (i.e., human hand vs. non-human agent) as well as by action-relevant features of goal objects (e.g., object size). The present study investigated the combined effects of these factors on 12-month-olds’ action prediction. Infants’ (N = 49) goal-directed gaze shifts were recorded as they observed 14 trials in which either a human hand or a mechanical claw reached for a small goal area (low-saliency goal) or a large goal area (high-saliency goal). Only infants who had observed the human hand reaching for a high-saliency goal fixated the goal object ahead of time, and they rapidly learned to predict the action goal across trials. By contrast, infants in all other conditions did not track the observed action in a predictive manner, and their gaze shifts to the action goal did not change systematically across trials. Thus, high-saliency goals seem to boost infants’ predictive gaze shifts during the observation of human manual actions, but not of actions performed by a mechanical device. This supports the assumption that infants’ action predictions are based on interactive effects of action-relevant object features (e.g., size) and own action experience.     

Negotiating time: the significance of timing in ending inpatient work

This paper discusses work with young people during their stay on an NHS psychiatric inpatient unit, especially focusing on the end of treatment and the appropriate timing of discharge into the community. When approaching the end of an admission, various factors are considered that seem particularly relevant to the decision of when a young person may be ready to leave and cope with the transition back to life outside the unit. Indications of medical stability, in patients where this has been an issue, is a factor of prime importance. Other important factors include family functioning; the availability of adequate ongoing local CAMHS support for the child and family; suitable school provision; and the identity of the child within a peer group. The reality of NHS resources and the demand for inpatient beds is another pressing consideration. The young person's own motivation emerges as crucial at this stage – towards the end of treatment – not only in terms of what is said, and therefore evident verbally, but also through signs of internal shifts in the child that indicate a capacity to re-engage with life outside in a lasting way. Decisions about when to stop are taken with all this in mind and when the decision does not seem straightforward, it can provoke considerable anxiety in the multi-disciplinary team. Clinical material from psychotherapy with a young adolescent boy with anorexia nervosa is used to illustrate some of the dilemmas.     

Self-regulation during a single performance episode: Mood-as-information in the absence of formal feedback

This investigation used a daily diary methodology to examine goal revision and effort allocation processes over a single, 2-weeks performance episode in which individuals prepared for a course exam. Growth curve modeling revealed that daily goal exhibited a curvilinear trend in which it was stable and relatively high at the beginning of the time period, but rapidly declined as the exam approached. Daily effort exhibited a trend opposite of the goal trend, remaining low and relatively stable at the beginning and increasingly rapidly as the exam approached. Current mood predicted daily goal revision, with positive mood being positively related to goal revision and negative mood being negatively related to goal revision. The traits of behavioral activation system (BAS) sensitivity and behavioral inhibition system (BIS) sensitivity moderated within-person relationships of positive and negative mood with goal revision. Simultaneous and lagged relationships among mood, goals, and daily effort were also examined.     

动词的延续性特征及瞬时时间副词对时间转换事件表征的影响

为考察语篇阅读中,汉语动词的延续性特征以及瞬时时间副词对时间转换事件表征的影响,采用探测-判断的语篇实时阅读技术分别进行了两个实验。实验1的结果表明,当描述转换前事件的动词是延续性动词时,短时转换句与瞬时转换句的阅读时间无显著差异;而当描述转换前事件的动词是短暂性动词时,短时转换句的阅读时间明显长于瞬时转换句的阅读时间。实验2的结果表明,当不在时间转换句前添加瞬时时间副词时,长时与短时转换句前探测词的再认时间存在显著差异;而当在时间转换句前添加瞬时时间副词时,长时与短时转换句前探测词的再认时间无显著差异。两个实验结果分别说明,动词的延续性特征和时间转换短句的结合影响了时间转换事件的表征,在长时转换句的前面添加瞬时时间副词缩短了长时转换事件的表征时间。     

Mild Affective Shifts and Creativity: Effects on Idea Generation,Evaluation, and Implementation Planning

This study investigated the impact of mild shifts in affective tone (i.e., pleasant vs. unpleasant) and arousal (i.e., high vs. low) on three creative processes. Undergraduates read short stories designed to induce affective shifts and then were asked to generate solutions to a complex business problem. Shifts in affective tone and arousal interacted to influence idea generation and implementation planning, but not idea evaluation. The strongest creative performance was exhibited by participants who experienced a stable and pleasantly toned, low-arousal (i.e., relaxed) state and by those who shifted to an unpleasantly toned, high-arousal (i.e., angry) state. In contrast, those who shifted to an unpleasantly toned, low-arousal (i.e., sad) state or a pleasantly toned, high-arousal (i.e., happy) state tended to exhibit poorer creative performance. These results demonstrate the need to revisit the popular conception that organizations should promote intense levels of pleasant affect to enhance employee creativity.
