Learning to identify objects as members of categories is an essential cognitive skill and learning to deploy attention effectively is a core component of that process. The present study investigated an assumption imbedded in formal models of categorization: error is necessary for attentional learning. Eye-trackers were used to record participants’ allocation of attention to task relevant and irrelevant features while learning a complex categorization task. It was found that participants optimized their fixation patterns in the absence of both performance errors and corrective external feedback. Optimization began immediately after each category was mastered and continued for many trials. These results demonstrate that error is neither necessary nor sufficient for all forms of attentional learning. 相似文献

Previous research shows that directed actions can unconsciously influence higher-order cognitive processing, helping learners to retain knowledge and guiding problem solvers to useful insights (e.g. Cook, S. W., Mitchell, Z., & Goldin-Meadow, S. (2008). Gesturing makes learning last. Cognition, 106, 1047-1058; Thomas, L. E., & Lleras, A. (2007). Moving eyes and moving thought: on the spatial compatibility between eye movements and cognition. Psychonomic Bulletin and Review, 14, 663-668). We examined whether overt physical movement is necessary for these embodied effects on cognition, or whether covert shifts of attention are sufficient to influence cognition. We asked participants to try to solve Duncker’s radiation problem while occasionally directing them, via an unrelated digit-tracking task, to shift their attention (while keeping their eyes fixed) in a pattern related to the problem’s solution, to move their eyes in this pattern, or to keep their eyes and their attention fixed in the center of the display. Although they reported being unaware of any relationship between the digit-tracking task and the radiation problem, participants in both the eye-movement and attention-shift groups were more likely to solve the problem than were participants who maintained fixation. Our results show that by shifting attention in a pattern compatible with a problem’s solution, we can aid participants’ insight even in the absence of overt physical movements. 相似文献

Visual scanpath recording was used to investigate the information processing strategies used by a prosopagnosic patient, SC, when viewing faces. Compared to controls, SC showed an aberrant pattern of scanning, directing attention away from the internal configuration of facial features (eyes, nose) towards peripheral regions (hair, forehead) of the face. The results suggest that SC's face recognition deficit can be linked to an inability to assemble an accurate and unified face percept due to an abnormal allocation of attention away from the internal face region. Extraction of stimulus attributes necessary for face identity recognition is compromised by an aberrant face scanning pattern. 相似文献

The effects of saccadic bilateral (horizontal) eye movements on memory for a visual event narrative were investigated. In the study phase, participants were exposed to a set of pictures accompanied by a verbal commentary describing the events depicted in the pictures. Next, the participants were asked either misleading or control questions about the depicted event and were then asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Finally, recognition memory was tested using the remember-know procedure. It was found that bilateral eye movements increased true memory for the event, increased recollection, and decreased the magnitude of the misinformation effect. The findings are discussed in terms of source monitoring, dual-process theories of memory and the potential neural foundations of such effects. 相似文献

This paper presents a review and summary of experimental findings on the role of attention in the preparation of saccadic eye movements. The focus is on experiments where performance of prosaccades (saccades towards a suddenly appearing item) and antisaccades (saccades of equal amplitude in the direction opposite to where the target moved) is compared. Evidence suggests that these two opposite responses to the same stimulus event entail competition between neural pathways that generate reflexive movements to the target and neural mechanisms involved in inhibiting the reflex and generating a voluntary gaze shift in the opposite direction to the target appearance. Evidence for such a competition account is discussed in light of a large amount of experimental findings and the overall picture clearly indicates that this competition account has great explanatory power when data on saccadic reaction times and error rates are compared for the two types of saccade. The role of attention is also discussed in particular in light of the finding that the withdrawal of attention by a secondary task 200 to 500 ms before the saccade target appears, leads to speeded antisaccades (without a similar increase in error rates), showing that the results do not simply reflect a speed-accuracy trade-off. This result indicates that the tendency for "reflexive" prosaccades is diminished when attention is engaged in a different task. Furthermore, experiments are discussed that show that as the tendency for a reflexive prosaccade is weakened, antisaccades are speeded up, further supporting the competition account of pro- and antisaccade generation. In the light of evidence from neurophysiology of monkeys and humans, a tentative model of pro- and antisaccade generation is proposed. 相似文献

This article argues for the importance of theoreticalreflections that originate from patients' experiences.Traditionally academic philosophers have linked their ability totheorize about the moral basis of medical practice to their roleas outside observer. The author contends that recently a new typeof reflection has come from within particular patientpopulations. Drawing upon a distinction created by AntonioGramsci, it is argued that one can distinguish the theorygenerated by traditional bioethicists, who are academicallytrained, from that of ``organic' bioethicists, who identifythemselves with a particular patient community. Thecharacteristics of this new type of bioethicist that are exploredin this article include a close association of memoir andphilosophy, an interrelationship of theory and praxis, and anintimate connection between the individual and a particularpatient community. 相似文献

Direction and the frequency of spontaneous head movements during the ITIs following forward and backward paired trials were
compared to an acquisition of a conditioned orienting (alpha) response directed to the side of the tone source. The head movements
were analyzed from video recordings using classification of head turns to preferred and to nonpreferred directions. The results
showed a significant increase in the alpha responses during the forward paired conditioning to the preferred direction and
rapid extinction during the subsequent backward conditioning sessions. Spontaneous head movements during the ITIs increased
to the same preferred direction as the conditioned alpha responses. The results of this experiment suggest that the response
initially elicited by the CS can later appear as “spontaneous,” instrumental behavior, the form and the nature of which is
determined by the characteristics of the conditioned alpha response developing as a result of classical conditioning. 相似文献

副中央凹文本对阅读有非常重要的作用,考察读者在注视何时起对其加工有助于解决阅读中词汇加工方式的理论问题,当前研究结果存在很大争论。本研究采用消失文本范式,操纵词n-1和n+1的呈现时间(0m/40ms),考察读者加工两侧副中央凹信息的时程。结果发现,相比0ms,在注视早期40ms内,词n+1的呈现能够显著促进阅读加工,而词n-1未对阅读产生影响,表明右侧副中央凹信息的加工发生在注视早期,而左侧则未发生在该早期阶段。结果支持阅读眼动控制的并列加工模型。 相似文献
