MP3播放器外观设计效果的眼动评估

以大学生为被试,利用眼动法和主观评定法,分析了大学生在评估不同颜色（银白色、红色）、不同外形（椭圆形、圆形、长方体形和四棱柱形）MP3播放器外观设计时的眼动特征。结果发现：对于MP3播放器的外观来说,被试最关注的区域是功能键区域,即就是关注MP3播放器的人机交流功能;对于不同外形的MP3播放器,被试对圆形MP3播放器最感兴趣。     

Toy-oriented changes in hand and joint kinematics during the emergence of purposeful reaching

Infants first consistently reach for objects between 3 and 5 months of age. In the months before reaching, infants produce a variety of arm movements. The relationship between these early arm movements and the emergence of purposeful reaching is still unclear. The purpose of the present study was to determine how groups of non-reaching, nearly reaching, and newly reaching infants changed the kinematics of their spontaneous arm movements in the presence of a toy. Five infants in each of these groups were observed with a high-speed motion capture system during trials with and without a toy present. Kinematic analyses examined 3D hand, shoulder, and elbow motions. Our results suggest that with a toy present, non-reachers altered their movement quantity whereas near- and new-reachers altered their movement quality through spatio-temporal dissociation and reorientation of the arm. When comparing the changes across groups we observed three preliminary patterns of toy-oriented changes. Our results join other studies to strengthen the relationship between early arm movements and purposeful reaching. Future longitudinal studies are now required to begin to fully understand the complex process by which infants adapt their early arm movements for purposeful behaviors.

胖负面身体自我女性对身体信息注意偏向成分的时间进程：一项眼动追踪研究

虽然目前大量研究基于Vitousek和Hollon (1990)提出的饮食失调认知模型对胖负面身体自我图式者或饮食失调者的注意偏向进行探讨, 但对其注意偏向的成分仍未得出一致结论, 且尚无研究查考其时间进程特点。研究采用更具生态效度的身体图片为实验刺激, 刺激呈现时间2000ms, 采用传统经典的点探测范式与眼动追踪技术结合, 探讨胖负面身体自我女性对身体信息注意偏向成分的时间进程。基于前人的工作(Castellanos et al., 2009; Garner, Mogg, & Bradley, 2006), 研究考察了四个眼动数据：首视点定向偏向分数、首视点潜伏期偏向分数、首视点注视时间偏向以及总注视时间偏向分数, 系统探讨了注意定向、探测时间、最初注意维持/回避以及总体注意维持/回避。眼动数据发现, 胖负面身体自我图式者对不同身体图片存在不同的注意偏向模式, 对胖图片为注意警觉—维持模式, 具体表现为早期加速探测、注意定向, 以及最初的注意维持和总体注意维持; 对瘦图片仅为注意警觉, 具体表现为早期加速探测; 行为数据支持实验组对胖图片的注意维持以及对身体图片的注意脱离困难。该结果部分支持Vitousek和Hollon (1990)的模型, 即负面身体自我图式能够易化对图式一致信息的加工, 而未发现对图式不一致信息的回避或抑制。     

词切分对印-英双语者阅读影响的眼动研究

以25名印-英双语者为被试,采用EyeLink2000眼动仪,探讨词切分对印-英双语者阅读的影响。实验一要求被试阅读印地语句子,实验二要求被试阅读英语句子,词切分方式有三种：正常条件、无空格隔词加灰条件和无空格条件。结果发现：（1）对印-英双语者阅读自己的两种官方语言来说,空格因素在其阅读中发挥着积极作用,删除空格会明显影响他们的阅读;（2）在无空格隔词加灰条件和无空格条件下,印-英双语者阅读英语时下降的速度显著低于阅读印地语的,这表明空格因素的作用会受语言特点的制约。     

When spiders appear suddenly: spider-phobic patients are distracted by task-irrelevant spiders

Fear is thought to facilitate the detection of threatening stimuli. Few studies have examined the effects of task-irrelevant phobic cues in search tasks that do not involve semantic categorization. In a combined reaction time and eye-tracking experiment we investigated whether peripheral visual cues capture initial attention and distract from the execution of goal-directed eye movements. Twenty-one spider-phobic patients and 21 control participants were instructed to search for a color singleton while ignoring task-irrelevant abrupt-onset distractors which contained either a small picture of a spider (phobic), a flower (non-phobic, but similar to spiders in shape), a mushroom (non-phobic, and not similar to spiders in shape), or no picture. As expected, patients' reaction times were longer on trials with spider distractors. However, eye movements revealed that this was not due to attentional capture by spider distractors; patients more often fixated on all distractors with pictures, but their reaction times were delayed by longer fixation durations on spider distractors. These data do not support automatic capture of attention by phobic cues but suggest that phobic patients fail to disengage attention from spiders.     

Why good thoughts block better ones: the mechanism of the pernicious Einstellung (set) effect

The Einstellung (set) effect occurs when the first idea that comes to mind, triggered by familiar features of a problem, prevents a better solution being found. It has been shown to affect both people facing novel problems and experts within their field of expertise. We show that it works by influencing mechanisms that determine what information is attended to. Having found one solution, expert chess players reported that they were looking for a better one. But their eye movements showed that they continued to look at features of the problem related to the solution they had already thought of. The mechanism which allows the first schema activated by familiar aspects of a problem to control the subsequent direction of attention may contribute to a wide range of biases both in everyday and expert thought - from confirmation bias in hypothesis testing to the tendency of scientists to ignore results that do not fit their favoured theories.     

Social Change Movements and the Struggle Over Meaning-Making: A Case Study of Domestic Violence Narratives

Social movement theorists have emphasized the important role of meaning-making for social change movements (e.g., D. A. Snow and R. D. Benford, 1992, In: A. D. Morris & C. M. Mueller (Eds.) Frontiers in social movement theory. Yale University Press, New Haven, CT, pp 133-155; C. M. Mueller, 1992, In: A. D. Morris & C. M. Mueller (Eds.) Frontiers in social movement theory. Yale University Press, New Haven, CT, pp 3-26). Using the domestic violence movement as a case study, this study undertakes a close analysis of advocates' narratives about the phenomenon of domestic violence. This analysis sheds light on the current status of the movement as a social change movement attempting to promote alternative understandings of domestic violence as a social, rather than individual, problem. Study findings provide some evidence that the domestic violence movement has become increasingly de-politicized by documenting a range of narratives that convey an apolitical, degendered, individual-level analysis of domestic violence.     

消失文本条件下词的预测性效应的眼动研究

通过考察消失文本条件下的词的预测性效应,探讨影响中文阅读眼动模式的控制因素,为中文阅读的眼动控制理论提供实证证据。以28名大学生为被试,在被试阅读实验句的同时记录其眼动轨迹。被注视的词的呈现时间设为80ms,在这种特殊的实验情境下,考察中文阅读眼动模式的影响因素。以词的预测性为自变量,以被试对目标词的首次注视时间、凝视时间和总注视时间为因变量。结果发现,在消失文本条件下,出现了显著的预测性效应。结果支持眼动的认知控制模型。
