汉字阅读材料的不同排列组合对字词认知速度及准确性的影响

本研究探讨了汉字阅读材料的不同组合对字词认知速度及准确性的影响。实验材料是一篇３２０个字的短文阅读材料,分成三种不同组合形式让被试从左往右发声念读．一种是顺意排列材料形式（即文章句子符合句法及词意）,一种是逆意排列材料形式（即将文章的字词逆反排列）;一种是随机排列材料形式（即将全文字词打乱随机排列）。实验结果表明：对顺意排列材料的念读效果最好,念读速度及准确性明显高于另外两种材料组合形式;中青年组被试的结果明显优于老年组及儿童组的结果．结果提示,对字词念读的认知加工过程明显受相邻字词关系的影响及字词句子化的影响．     

视觉形状知觉在近似数量系统和计算流畅性关系中的作用

已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。     

Object representations are biased toward each other through statistical learning

The visual system is remarkably efficient at extracting regularities from the environment through statistical learning. While such extraction has extensive consequences on cognition, it is unclear how statistical learning shapes the representations of the individual objects that comprise the regularities. Here we examine how statistical learning alters object representations. In three experiments, participants were exposed to either random arrays containing objects in a random order, or structured arrays containing object pairs where two objects appeared next to each other in fixed spatial or temporal configurations. After exposure, one object in each pair was briefly presented and participants judged the location or the orientation of the object without seeing the other object in the pair. We found that when an object reliably appeared next to another object in space, it was judged as being closer to the other object in space even though the other object was never presented (Experiments 1 and 2). Likewise, when an object reliably preceded another object in time, its orientation was biased toward the orientation of the other object even though the other object was never presented (Experiment 3). These results demonstrated that statistical learning fundamentally shapes how individual objects are represented in visual memory, by biasing the representation of one object toward its co-occurring partner. Importantly, participants in all experiments were not explicitly aware of the regularities. Thus, the bias in object representations was implicit. The current study reveals a novel impact of statistical learning on object representation: spatially co-occurring objects are represented as being closer in space, and temporally co-occurring objects are represented as having more similar features.     

初中生班级团体依恋、自悯与学习倦怠的关系

本研究采用青少年学习倦怠量表、班级团体依恋问卷、自悯量表、青少年父母同伴依恋问卷、生活满意度量表、和自编学业满意度问题对658名初中生进行问卷调查,考察当代初中生对其所在班级的团体依恋和自悯与学习倦怠之间的关系,并检验自悯在班级团体依恋和学习倦怠关系中的中介作用。结果发现：在控制了人口学变量、父母依恋、同伴依恋、学业满意度和生活满意度之后,（1）班级团体依恋焦虑和回避均能显著正向预测学习倦怠;（2）自悯显著负向预测学习倦怠;（3）自悯在班级团体依恋焦虑和学习倦怠的关系中起到完全中介的作用,而在班级团体依恋回避和学习倦怠的关系中起部分中介的作用。研究结果对于从班级团体依恋和自悯的角度理解中学生学习倦怠具有重要意义。     

Updating beliefs in light of uncertain evidence: Descriptive assessment of Jeffrey's rule

Jeffrey (1983) proposed a generalisation of conditioning as a means of updating probability distributions when new evidence drives no event to certainty. His rule requires the stability of certain conditional probabilities through time. We tested this assumption (“invariance”) from the psychological point of view. In Experiment 1 participants offered probability estimates for events in Jeffrey's candlelight example. Two further scenarios were investigated in Experiment 2, one in which invariance seems justified, the other in which it does not. Results were in rough conformity to Jeffrey's (1983) principle.     

Vision and abstraction: an empirical refutation of Nico Orlandi’s non-cognitivism

This article argues against the non-cognitivist theory of vision that has been formulated in the work of Nico Orlandi. It shows that, if we understand ‘representation’ in the way Orlandi recommends, then the visual system’s response to abstract regularities must involve the formation of representations. Recent experiments show that those representations must be used by the visual system in the production of visual experiences. Their effects cannot be explained by taking them to be non-visual effects involving attention or memory. This contradicts Orlandi’s version of the non-cognitivist hypothesis, but does so while vindicating her methodological position.     

The influence of need for cognitive closure on the attention‐recognition stage of preventive coping

The current study explored the influence of need for cognitive closure (NFCC) on preventive coping via its effects on the attention‐recognition stage and sought to determine whether this influence was moderated by individuals' existing knowledge. An experiment involving 90 university students used the vignette‐reading paradigm to explore the relationships between NFCC, attention and preventive coping behaviour. The results indicated that when preventive coping situations were consistent with participants' previous knowledge, people with high, relative to low, NFCC were more inclined to use preventive coping strategies. As a stage of preventive coping, gaining awareness of potential stressors mediated the relationship between NFCC and preventive coping. However, when coping situations were inconsistent with participants' knowledge, the relationship between NFCC and preventive coping was non‐significant.     

Statistical regularities guide the spatial scale of attention

Visual scenes contain information on both a local scale (e.g., a tree) and a global scale (e.g., a forest). The question of whether the visual system prioritizes local or global elements has been debated for over a century. Given that visual scenes often contain distinct individual objects, here we examine how regularities between individual objects prioritize local or global processing. Participants viewed Navon-like figures consisting of small local objects making up a global object, and were asked to identify either the shape of the local objects or the shape of the global object, as fast and accurately as possible. Unbeknown to the participants, local regularities (i.e., triplets) or global regularities (i.e., quadruples) were embedded among the objects. We found that the identification of the local shape was faster when individual objects reliably co-occurred immediately next to each other as triplets (local regularities, Experiment 1). This result suggested that local regularities draw attention to the local scale. Moreover, the identification of the global shape was faster when objects co-occurred at the global scale as quadruples (global regularities, Experiment 2). This result suggested that global regularities draw attention to the global scale. No participant was explicitly aware of the regularities in the experiments. The results suggest that statistical regularities can determine whether attention is directed to the individual objects or to the entire scene. The findings provide evidence that regularities guide the spatial scale of attention in the absence of explicit awareness.
