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. 相似文献

When spiders appear suddenly: spider-phobic patients are distracted by task-irrelevant spiders 总被引:4,自引:0,他引:4
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. 相似文献

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 总被引:2,自引:0,他引:2
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。 相似文献

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。 相似文献

Bilingualism has been observed to influence cognitive processing across the lifespan but whether bilingual environments have an effect on selective attention and attention strategies in infancy remains an unresolved question. In Study 1, infants exposed to monolingual or bilingual environments participated in an eye‐tracking cueing task in which they saw centrally presented stimuli followed by a target appearing on either the left or right side of the screen. Halfway through the trials, the central stimuli reliably predicted targets' locations. In Study 2, the first half of the trials consisted of centrally presented cues that predicted targets' locations; in the second half, the cue–target location relation switched. All infants performed similarly in Study 1, but in Study 2 infants raised in bilingual, but not monolingual, environments were able to successfully update their expectations by making more correct anticipatory eye movements to the target and expressing faster reactive eye latencies toward the target in the post‐switch condition. The experience of attending to a complex environment in which infants simultaneously process and contrast two languages may account for why infants raised in bilingual environments have greater attentional control than those raised in monolingual environments. 相似文献

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment‐to‐moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide the first evidence that image‐level object variability matters and may be the link that connects infant object manipulation to vocabulary development. Using head‐mounted eye tracking, the present study objectively measured individual differences in the moment‐to‐moment variability of visual instances of the same object, from infants’ first‐person views. Infants who generated more variable visual object images through manual object manipulation at 15 months of age experienced greater vocabulary growth over the next six months. Elucidating infants’ everyday visual experiences with objects may constitute a crucial missing link in our understanding of the developmental trajectory of object name learning. 相似文献

When and how do social movements form to mobilize action across national boundaries? In the context of the 2015 movement to support Syrian refugees, we develop an integrative model of transnational social movement formation shaped by pre-existing world-views (social dominance orientation and right-wing authoritarianism) and social media exposure to iconic events, resulting in an emergent group consciousness (“we are”, “we believe”, “we feel”). Group consciousness is, in turn, the proximal predictor of solidarity with refugees. Participants were from six countries: Hungary (N = 267), Romania (N = 163), Germany (N = 190), the United Kingdom (N = 159), the United States (N = 244) and Australia (N = 344). Multi-group structural equation models confirmed that group consciousness, shaped by individual differences and exposure to events through social media, was the proximal predictor of solidarity. The subjective meaning of group consciousness varied across samples, reflecting national differences. Results support the importance of considering individual and national differences, and group processes in understanding emergent social movements. 相似文献

Bimanual coordination requires task-specific control of the spatial and temporal characteristics of the movements of both hands. The present study focused on the spatial relationship between hand movements when their amplitude and direction were manipulated. In the experiment in question, participants were instructed to draw two lines simultaneously. These two lines were instructed to be drawn in mirror symmetric or perpendicular directions of each other while the length was instructed to be the same or different. The coordinative quality of amplitude control was compared when the task required symmetric and asymmetric bimanual spatial coordination patterns. Results showed that the amplitude accuracy decreased when different amplitudes and/or directions had to be generated simultaneously. The coordinative quality of direction was also compared when the task required symmetric and asymmetric bimanual spatial coordination patterns. Unlike amplitude, the direction accuracy was largely independent of coordination symmetry/asymmetry of direction or amplitude. The results suggest that the coordinative quality of amplitude control does not only interfere with amplitude asymmetry, but it also interferes with direction asymmetry. Moreover, in bimanual coordination amplitude control is more vulnerable to the influence of direction control demands than vice versa. 相似文献
