Combined with emotional expressions, eye gaze can provide essential information to indicate threat in the environment. The current study assessed the effects of eye gaze direction on infants’ neural processing of fearful and angry faces. Event‐related potentials were recorded from thirteen 7‐month‐old infants. Two face‐sensitive posterior components, the N290 and P400, as well as a frontocentral negative component (Nc), indicating attentional arousal, were sensitive to eye gaze direction and emotion. A larger Nc was observed for angry faces with direct compared to averted eye gaze. Fearful faces elicited a larger N290 than angry faces, whereas angry faces elicited a more prominent P400 regardless of eye gaze direction. The findings are discussed in terms of early social cognitive and neural development. 相似文献

孤独症儿童对社会刺激的注意行为存在缺陷,主要表现在对眼睛注视的定向注意和联合注意受损。回溯研究发现,孤独症儿童在婴儿期就表现出对社会刺激如面孔、名字等的注意损伤。然而采用空间注意线索化范式,发现既有证据表明他们能对眼睛注视线索发出注意定向行为,也有相反的证据。孤独症儿童联合注意的缺损主要表现在,不能对他人的社会指向做出反应,也不能主动发出注意分享行为。文章回顾了孤独症儿童对眼睛注视线索引起的注意定向的研究,分析了结果存在矛盾的可能原因,列举了他们在联合注意缺损上的主要表现,并总结了与其社会性注意相关神经基础的异常。 相似文献

社会认知神经科学是社会心理学与认知神经科学相结合的跨学科研究领域,旨在对社会心理现象在神经、认知和社会三个水平实现整合性研究。当前的研究主要集中于刻板印象、态度与态度改变、他人知觉、自我认知以及情绪与认知交互作用等传统社会心理学的范畴上面,主要范式是应用认知神经科学的方法来验证社会心理学在这些范畴上的各种不同理论观点,并在某些方面取得了突破性进展,但仍存在着广泛的发展空间。未来的研究应采用整合性研究与分离性研究相结合、自下而上与自上而下相结合的研究思路,这有助于建立心理学统一的研究范式。 相似文献

To test the hypothesis that biological motion perception is developmentally integrated with important social cognitive abilities, 12-month-olds ( N = 36) were shown a display of a human point-light figure turning to observe a target. Infants spontaneously and reliably followed the figure's "gaze" despite the absence of familiar and socially informative features such as a face or eyes. This suggests that biological motion displays are sufficient to convey rich psychological information such as attentional orientation and is the first evidence to show that biological motion perception and social cognitive abilities are functionally integrated early in the course of typical development. The question of whether common neural substrates for biological motion perception and analysis of gaze direction underlies the functional integration seen behaviorally is discussed. 相似文献

ABSTRACT— Advances in neuroscience during the past century have yielded important insights into mental functioning, but their implications for the field of education have remained largely unexplored. In a bold attempt to bridge this gap, Immordino-Yang presents findings from 2 boys, Nico and Brooke, each of whom lost half of his brain. The remarkable recovery of functions in the 2 boys highlights the degree to which children's emotional and social experiences shape brain development, as well as the importance of plasticity. Immordino-Yang places emphasis on cognitive plasticity—the ability to use different strategies in solving a task—which is clearly evident in the boys' performance. It is possible, however, that neural plasticity may have occurred as well, either prior to or after surgery. Although it may not be possible to distinguish between cognitive and neural plasticity at this point, Immordino-Yang makes a crucial contribution. By placing these findings in an educational context and presenting their implications in a clear and compelling fashion, she successfully brings neuroscience and education a notch closer. 相似文献

In humans, effortful cognitive processing frequently takes place during social interaction, with eye contact being an important component. This study shows that the effect of eye contact on memory for nonsocial information is different in children with typical development than in children with autism, a disorder of social communication. Direct gaze facilitated memory performance in children with typical development (n = 25, 6 years old), but no such facilitation was seen in the clinical group (n = 10, 6 years old). Eye tracking conducted during the cognitive test revealed strikingly similar patterns of eye movements, indicating that the results cannot be explained by differences in overt attention. Collectively, these findings have theoretical significance and practical implications for testing practices in children. 相似文献

This study examined the development of joint attention in 95 infants assessed between 9 and 18 months of age. Infants displayed significant test-retest reliability on measures of following gaze and gestures (responding to joint attention, RJA) and in their use of eye contact to establish social attention coordination (initiating joint attention, IJA). Infants displayed a linear, increasing pattern of age-related growth on most joint attention measures. However, IJA was characterized by a significant cubic developmental pattern. Infants with different rates of cognitive development exhibited different frequencies of joint attention acts at each age, but did not exhibit different age-related patterns of development. Finally, 12-month RJA and 18-month IJA predicted 24-month language after controlling for general aspects of cognitive development. 相似文献

Regulatory aspects of development can best be understood by research that conceptualizes relations between cognition and emotion. The neural mechanisms associated with regulatory processes may be the same as those associated with higher order cognitive processes. Thus, from a developmental cognitive neuroscience perspective, emotion and cognition are dynamically linked and work together to process information and execute action. This article highlights the authors' recent efforts at integrating emotion regulation and cognitive processing during the first year of life by focusing on the methodological criteria outlined by Cole, Martin, and Dennis (this issue), and it discusses the idea that emotion and cognition are an intricately bound developmental process. 相似文献

Attending to where others are looking is thought to be of great adaptive benefit for animals when avoiding predators and interacting with group members. Many animals have been reported to respond to the gaze of others, by co-orienting their gaze with group members (gaze following) and/or responding fearfully to the gaze of predators or competitors (i.e., gaze aversion). Much of the literature has focused on the cognitive underpinnings of gaze sensitivity, namely whether animals have an understanding of the attention and visual perspectives in others. Yet there remain several unanswered questions regarding how animals learn to follow or avoid gaze and how experience may influence their behavioral responses. Many studies on the ontogeny of gaze sensitivity have shed light on how and when gaze abilities emerge and change across development, indicating the necessity to explore gaze sensitivity when animals are exposed to additional information from their environment as adults. Gaze aversion may be dependent upon experience and proximity to different predator types, other cues of predation risk, and the salience of gaze cues. Gaze following in the context of information transfer within social groups may also be dependent upon experience with group-members; therefore we propose novel means to explore the degree to which animals respond to gaze in a flexible manner, namely by inhibiting or enhancing gaze following responses. We hope this review will stimulate gaze sensitivity research to expand beyond the narrow scope of investigating underlying cognitive mechanisms, and to explore how gaze cues may function to communicate information other than attention. 相似文献

Educational Neuroscience: Defining a New Discipline for the Study of Mental Representations 总被引：1，自引：0，他引：1
ABSTRACT— Is educational neuroscience a “bridge too far”? Here, we argue against this negative assessment. We suggest that one major reason for skepticism within the educational community has been the inadequate definition of the potential role and use of neuroscience research in education. Here, we offer a provisional definition for the emerging discipline of educational neuroscience as the study of the development of mental representations. We define mental representations in terms of neural activity in the brain. We argue that there is a fundamental difference between doing educational neuroscience and using neuroscience research results to inform education. While current neuroscience research results do not translate into direct classroom applications, educational neuroscience can expand our knowledge about learning, for example, by tracking the normative development of mental representations. We illustrate this briefly via mathematical educational neuroscience. Current capabilities and limitations of neuroscience research methods are also considered. 相似文献

The primary goal of the emerging field of educational neuroscience and the broader movement called Mind, Brain, and Education is to join biology with cognitive science, development, and education so that education can be grounded more solidly in research on learning and teaching. To avoid misdirection, the growing worldwide movement needs to avoid the many myths and distortions in popular conceptions of brain and genetics. It should instead focus on integrating research with practice to create useful evidence that illuminates the brain and genetic bases as well as social and cultural influences on learning and teaching. Scientists and educators need to collaborate to build a strong research foundation for analyzing the “black box” of biological and cognitive processes that underpin learning. 相似文献

Children perform worse than adults on tests of cognitive flexibility, which is a component of executive function. To assess what aspects of a cognitive flexibility task (cued switching) children have difficulty with, investigators tested where eye gaze diverged over age. Eye-tracking was used as a proxy for attention during the preparatory period of each trial in 48 children ages 8–16 years and 51 adults ages 18–27 years. Children fixated more often and longer on the cued rule, and made more saccades between rule and response options. Behavioral performance correlated with gaze location and saccades. Mid-adolescents were similar to adults, supporting the slow maturation of cognitive flexibility. Lower preparatory control and associated lower cognitive flexibility task performance in development may particularly relate to rule processing. 相似文献
