Some recent evidence suggests that mental rotation of characters in children aged 7 or 8 years might be lateralized to the left parietal hemisphere. An alternative statement exists, however, the finding might be completely unspecific for mental rotation but either be simply a function of task difficulty or a consequence of the use of characters as stimuli. To test these alternatives, ERPs of 24 second graders were measured twice: (a) during mental rotation with characters as stimuli and orientations of 30°, 90°, or 150° and (b) during memory scanning with characters as stimuli and set sizes of 1, 2, or 3 letters. In both cases, an amplitude modulation was found. The effect of mental rotation as a function of character orientation turned out to be lateralized to the left parietal hemisphere. The effect of memory scanning as a function of set size, however, turned out to be completely non-lateralized. Thus, children's left hemisphere activation during mental rotation is reliable as well as specific. 相似文献

Dehumanisation describes perceiving a person as nonhuman in some ways, such as lacking a mind. Social psychology is beginning to understand cognitive and affective causes and mechanisms—the psychological how and why of dehumanisation. Social neuroscience research also can inform these questions. After background on social neural networks and on past dehumanisation research, the article contrasts (a) research on fully humanised person perception, reviewing studies on affective and cognitive factors, specifically mentalising (considering another's mind), with (b) dehumanised perception, proposing neural systems potentially involved. Finally, the conclusion suggests limitations of social neuroscience, future research directions, and real-world consequences of this all-too-human phenomenon. 相似文献

In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We review ERPs modulated by cognitive processes during sleep: N1, Mismatch Negativity (MMN), P2, P3, N400-like, N300-N550, among others. The review shows that there are different cognitive discriminations during sleep related to the frequency, intensity, duration, saliency, novelty, proportion of appearance, meaning, and even sentential integration of stimuli. The fascinating results of cognitive processing during sleep imply serious challenges for cognitive models. The studies of ERPs, together with techniques of neuroimaging, have demonstrated the existence of cognitive processing during sleep. A fundamental question to be considered is if these cognitive phenomena are similar to processing that occurs during wakefulness. Based on this question we discussed the existence of possible mechanisms associated with sleep, as well as the specific cognitive and neurophysiologic differences of wakefulness and sleep. Much knowledge is still required to even understand the conjunction of dramatic changes in cerebral dynamics and the occurrence of cognitive processes. We propose some insights based on ERPs research for further construction of theoretical models for integrating both cognitive processing and specific brain sleep dynamics. 相似文献

In this article, I develop an account of the use of intentional predicates in cognitive neuroscience explanations. As pointed out by Maxwell Bennett and Peter Hacker, intentional language abounds in neuroscience theories. According to Bennett and Hacker, the subpersonal use of intentional predicates results in conceptual confusion. I argue against this overly strong conclusion by evaluating the contested language use in light of its explanatory function. By employing conceptual resources from the contemporary philosophy of science, I show that although the use of intentional predicates in mechanistic explanations sometimes leads to explanatorily inert claims, intentional predicates can also successfully feature in mechanistic explanations as tools for the functional analysis of the explanandum phenomenon. Despite the similarities between my account and Daniel Dennett's intentional-stance approach, I argue that intentional stance should not be understood as a theory of subpersonal causal explanation, and therefore cannot be used to assess the explanatory role of intentional predicates in neuroscience. Finally, I outline a general strategy for answering the question of what kind of language can be employed in mechanistic explanations. 相似文献

Through an examination of the varied paradoxes embedded within the phenomenon of genital exhibitionism, the author establishes exhibitionism as a paradigm for interpersonal relations whereby one individual entices another to lose himself, to a benign or dangerous degree, in a presented portrayal/enactment. Efforts to entice that cause an extreme loss of the subject's sense of self--making it exceedingly hard to break free of--are designed to render the subject powerless and take psychic possession of him. The perpetrator accomplishes this feat by interacting with his victim in ways capable of producing a sudden and profound regression with sufficient loss of autonomous ego functioning that the subject finds it hard, if not impossible, to act on his own behalf. The essential feature of the perpetrator's efforts is his violation of the unspoken but understood rules of interpersonal engagement that, when violated, cause extreme disorientation and a loss of trust in one's most basic assumptions about how humans treat one another. When this happens, we would describe the interaction as having been perverted to serve the exclusive needs of the predator--to gain as complete control over the other as possible. 相似文献

Increasing working memory (WM) capacity is often cited as a major influence on children's development and yet WM capacity is difficult to examine independently of long-term knowledge. A computational model of children's nonword repetition (NWR) performance is presented that independently manipulates long-term knowledge and WM capacity to determine the relative contributions of each in explaining the developmental data. The simulations show that (a) both mechanisms independently cause the same overall developmental changes in NWR performance, (b) increase in long-term knowledge provides the better fit to the child data, and (c) varying both long-term knowledge and WM capacity adds no significant gains over varying long-term knowledge alone. Given that increases in long-term knowledge must occur during development, the results indicate that increases in WM capacity may not be required to explain developmental differences. An increase in WM capacity should only be cited as a mechanism of developmental change when there are clear empirical reasons for doing so. 相似文献

More than six decades after Freud's death, psychoanalysts are certainly not more unified in their view of the concept of the unconscious—its structure and its way of working—than in ‘the good old days’. Challenges are facing psychoanalysis from many perspectives, urging psychoanalysts to continuously reconsider their theoretical grounds. This paper pursues three lines of argumentation concerning the Unconscious. The first line concerns the relation to neuroscience and this paper suggests the concept of background feelings (Damasio) as a contribution to another understanding of deficits in the psychoanalytic relationship. The second line concerns the relation to cognitive semiotics, and here, the paper stresses the concept of basic image sehemata as a possible link between the subject's pre-reflective awareness of the other and the internal world of phantasy. The third line pursues a concept of the analytic interpretation which is close to the Freudian idea that psychoanalysis is the communication between two Unconscious, and, consequently, that the psycho-analytic interpretation is not per se a conscious act. 相似文献
