Processing efficiency in anxiety: Evidence from eye-movements during visual search

It is generally held that anxiety is characterized by an attentional bias for threatening information. In recent years there has been an important debate whether these biases reside at the level of attentional selection (threat detection) or attentional processing after threat detection (attentional disengagement). In a visual search task containing emotional facial expressions, eye-movements were examined before and after threat detection in high and low trait anxious individuals to further elucidate the temporal unfolding of attentional bias. Results indicated that high-anxious individuals neither showed facilitated orienting to threat nor impaired disengagement of visual attention from threat. Interestingly, the presence of threat in the visual search display was associated with increased decision times in high-anxious individuals. These results challenge some of the current views on attentional bias to threat but indicate that emotional information reduces processing efficiency in anxiety.     

An on-line study of Japanese nesting complexity

This paper reports the results of a self-paced reading experiment in Japanese in which the materials consisted of four versions of successively more nested syntactic structures. It was found that (1) people read the more nested materials slower than the less nested materials; and (2) the locus of the relative slowdown occurred early in the nested structures. There was no corresponding slowdown when processing the verbs at the end of each clause. The results are therefore not predicted by retrieval-based integration accounts of syntactic complexity. Rather, the results support expectation-based accounts of syntactic complexity for these materials.     

心理定势发生机制的模型建构

心理定势作为个体的一种预备状态,是先前的活动倾向对后来活动的影响,前苏联格鲁吉亚学派围绕它建立了较为完备的传统心理定势理论。而该文则希冀超越传统社会心理学的视角,以信息加工的心理学视角,使用图式理论重新阐释心理定势现象发生的内在作用机制,尝试建构“定势现象的图式激活过程理论模型”。     

How Readability Shapes Social Media Engagement

We suggest that text readability plays an important role in driving consumer engagement on social media. Consistent with a processing fluency account, we find that easy‐to‐read posts are more liked, commented on, and shared on social media. We analyze over 4,000 Facebook posts from Humans of New York, a popular photography blog on social media, over a 3‐year period to see how readability shapes social media engagement. The results hold when controlling for photo features, story valence, and other content‐related characteristics. Experimental findings further demonstrate the causal impact of readability and the processing fluency mechanism in the context of a fictitious brand community. This research articulates the impact of processing fluency on brief word‐of‐mouth transmissions in the real world while empirically demonstrating that readability as a message feature matters. It also extends the impact of processing fluency to a novel behavioral outcome: commenting and sharing actions.     

效能信念、加工方式和困难应对策略——关于自我调节学习的特点及各成分间关系的探讨

自我调节学习是一个复杂的系统,效能信念、加工方式、应对策略分别反映着自我调节学习的动机、认知、行为侧面。本研究通过对效能信念、加工方式、应对策略三者进行相关分析,探讨了自我调节学习各成分之间的关系;同时,对于自我调节学习各成分与学业成绩之间的关系亦作了探讨。在这两部分研究结论的基础上,提出了自我调节学习的理想模式,并对被试群体自我调节学习的现有状况与这一理想模式进行了对照。     

On the benefits of thinking unconsciously: Unconscious thought can increase post-choice satisfaction

This work compares conscious thought and unconscious thought in relation to quality of choice. Earlier work [Dijksterhuis, A. (2004). Think different: The merits of unconscious thought in preference development and decision making. Journal of Personality and Social Psychology, 87, 586-598] has shown that people make better choices after engaging in unconscious thought (i.e., unconscious activity during a period of distraction) rather than in conscious thought. However, the evidence was obtained for choices between hypothetical alternatives with quality of choice operationalized normatively. As quality of decision is essentially subjective, in the current experiment participants chose between real objects with quality operationalized as post-choice satisfaction. In a paradigm based on work by Wilson and colleagues [Wilson, T. D., Lisle, D., Schooler, J. W., Hodges, S. D., Klaaren, K. J., & LaFleur, S. J. (1993). Introspecting about reasons can reduce post-choice satisfaction. Personality and Social Psychology Bulletin, 19, 331-339], participants were briefly presented with five art posters, and chose one either (a) immediately, (b) after thorough conscious thinking about each poster, or (c) after a period of distraction. Participants took their favorite poster home and were phoned 3-5 weeks later. As hypothesized, unconscious thinkers were more satisfied with their choice than participants in the other two conditions.     

Fluid intelligence, memory span, and temperament difficulties predict academic performance of young adolescents

There are several candidate measures when asking which psychological construct significantly predicts academic performance. Hundreds of studies have addressed this issue by measuring intelligence, basic cognitive processes, or personality. However, the simultaneous consideration of a broad and varied array of measures is much less common. Here we consider several cognitive and personality measures concurrently to define latent factors representing six constructs of presumed interest: fluid intelligence, short-term memory, working memory, processing speed, controlled attention, and temperament difficulties. One hundred and thirty-five secondary school students were tested. Their academic performance was measured by average grades in the nine scholastic areas of their curriculum. The main finding shows that a latent factor defined by fluid intelligence and memory span along with a latent factor defined by impulsiveness, sensation seeking, and lack of fear account for an impressive figure of 60% of the variance in academic performance.     

智能结构三层次理论述评

近些年来,在认知领域,理论整合的趋势日益强烈,德米特里欧提出了一个关于人类智能结构与发展的“三层次”理论,使人们看到了理论整合令人鼓舞的前景。该理论认为人类智能是一个三层次体系,包括限定了信息加工潜力的加工系统、由一组用以理解不同现实和知识领域的专门化的能力系统组成的环境指向系统以及对这些系统起监控作用的超认知系统。最后,对该理论作了评价。     

Probing the influence of unconscious fear-conditioned visual stimuli on eye movements

Efficient threat detection from the environment is critical for survival. Accordingly, fear-conditioned stimuli receive prioritized processing and capture overt and covert attention. However, it is unknown whether eye movements are influenced by unconscious fear-conditioned stimuli. We performed a classical fear-conditioning procedure and subsequently recorded participants’ eye movements while they were exposed to fear-conditioned stimuli that were rendered invisible using interocular suppression. Chance-level performance in a forced-choice-task demonstrated unawareness of the stimuli. Differential skin conductance responses and a change in participants’ fearfulness ratings of the stimuli indicated the effectiveness of conditioning. However, eye movements were not biased towards the fear-conditioned stimulus. Preliminary evidence suggests a relation between the strength of conditioning and the saccadic bias to the fear-conditioned stimulus. Our findings provide no strong evidence for a saccadic bias towards unconscious fear-conditioned stimuli but tentative evidence suggests that such an effect may depend on the strength of the conditioned response.
