Facial examiners make visual comparisons of face images to establish the identities of persons in police investigations. This study utilised eye-tracking and an individual differences approach to investigate whether these experts exhibit specialist viewing behaviours during identification, by comparing facial examiners with forensic fingerprint analysts and untrained novices across three tasks. These comprised of face matching under unlimited (Experiment 1) and time-restricted viewing (Experiment 2), and with a feature-comparison protocol derived from examiner casework procedures (Experiment 3). Facial examiners exhibited individual differences in facial comparison accuracy and did not consistently outperform fingerprint analysts and novices. Their behaviour was also marked by similarities to the comparison groups in terms of how faces were viewed, as evidenced from eye movements, and how faces were perceived, based on the made feature judgements and identification decisions. These findings further understanding of how facial comparisons are performed and clarify the nature of examiner expertise. 相似文献

不规则几何图形识别取样特征的眼动研究 总被引:1,自引:0,他引:1
探讨不规则几何图形识别中取样的眼动特征。被试为12名大学生,刺激材料为20个不规则几何图形,采用EyelinkII型眼动仪。结果发现,随作业难度加大,被试在认知加工中的有效取样时间比显著下降。在不良视觉条件下,图形信息的取样点数量显著减少,眼动扫视路径显著增长。在识别旋转图形时,有效取样时间下降,取样点数量增加,眼动扫视路径增长。图形信息的显示条件与显示方式的交互作用对图形识别的反应时、取样点的数量和眼动扫视路径长度的影响显著。 相似文献

语音回路与阅读理解关系的眼动研究 总被引:4,自引:0,他引:4
语音回路是工作记忆中的一个重要成分。由于工作记忆在言语理解中有重要作用,所以负责加工语音信息的语音回路可能也和阅读理解有密切关系。但是,迄今为止直接研究语音回路影响阅读理解的研究不是很多,而且得出的结论也不太一致。研究使用眼动分析方法探讨语音回路与汉语阅读理解的关系。研究采用抑制发音和错误干扰相结合的范式考查正常条件下和抑制发音条件下的阅读特点的差别性。结果表明:(1)在一般阅读难度情况下,语音回路会延缓阅读速度;(2)两种阅读条件下都出现了同音效应,即同音字的首次注视时间、总注视时间都比非同音字短;(3)语音在汉语阅读的早期就发挥了作用,而且同音字错误比非同音字错误更容易被恢复 相似文献

By using the Gezi Park protests that took place in Turkey in 2013 as a case, we explore the significance of emotional echo-chamber involved in protests. The analyses are composed of thirty-seven interviews conducted with activists on how they define and understand their preferences and motivations for protesting. We discuss how participants get influenced by beliefs, motives and opinions and bring forth the changes of emotions during such processes and help create an emotional echo-chamber. 相似文献

Previous studies have shown that the human visual system can detect a face and elicit a saccadic eye movement toward it very efficiently compared to other categories of visual stimuli. In the first experiment, we tested the influence of facial expressions on fast face detection using a saccadic choice task. Face-vehicle pairs were simultaneously presented and participants were asked to saccade toward the target (the face or the vehicle). We observed that saccades toward faces were initiated faster, and more often in the correct direction, than saccades toward vehicles, regardless of the facial expressions (happy, fearful, or neutral). We also observed that saccade endpoints on face images were lower when the face was happy and higher when it was neutral. In the second experiment, we explicitly tested the detection of facial expressions. We used a saccadic choice task with emotional-neutral pairs of faces and participants were asked to saccade toward the emotional (happy or fearful) or the neutral face. Participants were faster when they were asked to saccade toward the emotional face. They also made fewer errors, especially when the emotional face was happy. Using computational modeling, we showed that this happy face advantage can, at least partly, be explained by perceptual factors. Also, saccade endpoints were lower when the target was happy than when it was fearful. Overall, we suggest that there is no automatic prioritization of emotional faces, at least for saccades with short latencies, but that salient local face features can automatically attract attention. 相似文献

A new dopaminergic regulation hypothesis is proposed based on two experiments exploring eye-movement effects. In the Eye Movement Desensitization and Reprocessing (EMDR) and Saccade-Induced Retrieval Enhancement (SIRE) domains, eye-movement mechanisms are mainly studied with explicit measures. Here implicit and explicit measures of emotion and memory for positive and negative pictures were investigated after eye movements or fixation in extreme right-handers. Eye movements enhanced explicit recognition predominantly for negative pictures. The absence of implicit repetition priming in both experiments supported a dissociation between implicit and explicit memory. Motivational eye-movement effects emerged but implicit and explicit affect remained unchanged. Experiment 2 revealed, after initial freezing to negative pictures, an acceleration, particularly of approach responses. Eye movements are postulated to foster approach towards negative memories, and promote, though dopaminergic pathways from the Superior Colliculus, enhanced explicit memory and active emotion regulation, primarily in persons with a collateralization of eye and dopamine dominance. 相似文献

Humans can extract a great deal of information about others very quickly. This is partly because the face automatically captures observers’ attention. Specifically, the eyes can attract overt attention. Although it has been reported that not only the eyes but also the nose can capture initial oculomotor movement in Eastern observers, its generalizability remains unknown. In this study, we applied the “don’t look” paradigm wherein participants are asked not to fixate on a specific facial region (i.e., eyes, nose, and mouth) during an emotion recognition task with upright (Experiment 1) and inverted (Experiment 2) faces. In both experiments, we found that participants were less able to inhibit the initial part of their fixations to the nose, which can be interpreted as the nose automatically capturing attention. Along with previous studies, our overt attention tends to be attracted by a part of the face, which is the nose region in Easterner observers. 相似文献

快速脱离假说和信号抑制假说都是将传统的自下而上捕获和自上而下控制结合起来的混合模式假说。快速脱离假说认为突显干扰物总能在第一时间自下而上地捕获注意, 当突显干扰物与任务要求不符时, 注意会迅速脱离该位置。信号抑制假说认为突显干扰物都会产生“注意我”的信号, 当突显干扰物与任务要求不符时, 该信号会被自上而下地抑制以阻止注意捕获发生。前者相关的研究多采用空间线索提示范式和眼动脱离范式, 实验中被试采取独子探测策略, 而后者相关的研究多采用额外单例范式的变式, 实验中被试采取特征探测策略。未来研究应采用不同的刺激类型和实验方法进一步为两个假说提供证据支持, 同时要关注奖赏、训练等因素对“捕获-脱离”和“信号-抑制”的影响。 相似文献

Recent studies have increasingly acknowledged the dynamic relationship between emotions and space in social movements. They, however, have seldom tied emotions and space to time when discussing activists’ emotions and their tactical choices. This paper studies the 2014 Umbrella Movement in Hong Kong and explores how collective memory and generational experiences—two intertwined notions of time—shaped how activists felt and how they designed and deployed a spatial tactic. The Umbrella Movement was characterized by miscellaneous emotions and intense disputes among activists regarding how to best use spatial occupation to fight for democratization before and during the struggle. Using a qualitative dataset that contains textual and interview data, I argue that while emotions and the political-cultural characteristics of contentious space were two factors in informing tactical choices, collective memory and generational experiences were key to understanding the rise of the movement and its characteristics. Experiencing different political events in their years of early adulthood, young and veteran activists felt differently in the context of 2013–2014, which led them to embrace disjunctive views on the pace, sequence, and bodily action for the same tactic of spatial occupation and dissimilar emotional management strategies. This created ongoing internal clashes before and during the movement. 相似文献
