Images of faces manipulated to make their shapes closer to the average are perceived as more attractive. The influences of symmetry and averageness are often confounded in studies based on full-face views of faces. Two experiments are reported that compared the effect of manipulating the averageness of female faces in profile and full-face views. Use of a profile view allows a face to be ”morphed“ toward an average shape without creating an image that becomes more symmetrical. Faces morphed toward the average were perceived as more attractive in both views, but the effect was significantly stronger for full-face views. Both full-face and profile views morphed away from the average shape were perceived as less attractive. It is concluded that the effect of averageness is independent of any effect of symmetry on the perceived attractiveness of female faces.  相似文献

It is argued that the recent criticism by Fodor (Cognition 75 (2000) 29) of "cheater detection" in the Wason selection task is based upon a false presumption about what the task entails. Fodor compares two different ways of presenting the task, rather than two different task domains (social and non-social). Consequently, the conclusion that the selection task can tell us nothing about either the architecture or the history of cognition is invalid. Fodor's explanation of the Wason selection task is examined experimentally and compared to predictions derived from social contract theory (Cognition 31 (1989) 187). It is concluded that, although Fodor's variant of the Wason selection task improves performance, this improvement is independent of the task domain and is insufficient to account for the "cheater detection" effect.  相似文献

This paper analyzes the causes for large differences in difficulty of various isomorphic versions of the Tower of Hanoi problem. Some forms of the problem take 16 times as long to solve, on average, as other versions. Since isomorphism rules out size of task domain as a determinant of relative difficulty, these experiments seek and find causes for the differences in features of the problem representation. Analysis of verbal protocols and the temporal patterning of moves allows the problem-solving behavior to be divided into exploratory and final-path phases. Entry into the final-path phase depends on acquisition of the ability to plan pairs of moves, an achievement made difficult by the working memory load it entails. This memory load can be reduced by automating the rules governing moves, either through problem exploration or training. Once automation has occurred, the solution is obtained very rapidly. Memory load is also proposed as the locus of other differences in difficulty found between various problem representations.  相似文献

I am concerned to understand that relation to a situation which we call fearing it. Some say this cannot be done: it is a brute fact about us that we fear certain things and we understand another's fear when we see that he confronts a situation of this sort (a basic fear object) or one which he understandably associates with this sort. In Section I, I argue that being associated with a basic fear object will not usefully explain a current fear. In Section II, I argue that the obvious candidates for being basic fears will not do the required work. The notion should be rejected. I then argue that to fear an object is to take it as exhibiting one's lack of control and I proceed to describe the nature and content of this notion.  相似文献

An overview is given for symposium papers originally presented at the Gatlinburg Conference on Research and Theory in Mental Retardation and Developmental Disabilities. Bray and Turner, in answering the symposium question “Why are the mentally retarded strategically deficient?” develop the position that situation-related variables and a person's comprehension of the “problem of remembering” leads to “production anomalies” rather than “strategy deficiencies.” Borkowski, Carr, and Pressley develop a case for deficiencies in metacognitive and motivational components as the reason for strategy deficiencies. Turnure attributes strategy deficiencies to impoverished learning of “situated meaning,” normally acquired as a result of informal instruction. The discussants, Belmont and Mitchell, provide an integration of these papers and discuss the influence of perceived task difficulty on strategy use.  相似文献

In an effort to stimulate and guide empirical work within a functional framework, this paper provides a conceptual model of the social functions of autobiographical memory (AM) across the lifespan. The model delineates the processes and variables involved when AMs are shared to serve social functions. Components of the model include: lifespan contextual influences, the qualitative characteristics of memory (emotionality and level of detail recalled), the speaker's characteristics (age, gender, and personality), the familiarity and similarity of the listener to the speaker, the level of responsiveness during the memory-sharing process, and the nature of the social relationship in which the memory sharing occurs (valence and length of the relationship). These components are shown to influence the type of social function served and/or, the extent to which social functions are served. Directions for future empirical work to substantiate the model and hypotheses derived from the model are provided.  相似文献

The BJGC 's (2000) symposium on guidance, psychotherapy and counselling reviewed the developments of these activities in the United Kingdom in the past and present, and then looked to the future at the turn of this millennium.The picture emerged of professionally dominated enterprises in which the client's point-of-view is obscure. This article explores why this is the case and how the client's perspective can reinforce the political as well as the therapeutic value of counselling, psychotherapy and guidance.  相似文献

Achieving and maintaining happiness can be difficult, especially when people are not engaging in the activities they know facilitate it. ‘Flow’ activities require clear rules, challenge, a high investment of energy, and have been shown to promote long-term happiness better than low investment, passive activities. Do people know this? In two studies, we found that, despite recognizing that flow activities are more likely to facilitate happiness, people nevertheless participated in passive leisure significantly more often in a typical week. Participants rated passive activities as being significantly more enjoyable, requiring less effort, and being less daunting to get started than flow activities. Participants’ engagement in flow activities was significantly predicted by how enjoyable the activities were perceived to be, whereas how daunting those activities were rated predicted non-engagement. Passive activity engagement was only significantly predicted by enjoyment. Suggestions for enabling people to rise above the barriers to flow activities are offered.  相似文献

Research on text comprehension shows that readers construct a model of the situation described in a narrative. A major factor in constructing a situational model is the perspective from which the action of the narrative is imagined. J. B. Black, T. J. Turner, and G. H. Bower (1979) found that adults recall a deictic verb of motion more accurately if it is spatially consistent with the point of view of the main protagonist. Recall is more accurate for the verbs come and bring if they describe a movement toward the protagonist; recall is more accurate for go and take if they describe a movement away from the protagonist. Thus, adults interpret movements in a narrative from the perspective of the protagonist. This study indicates that 3- and 4-year-old children show the same pattern of recall. They accurately recall verbs of motion that are consistent with the protagonist's perspective but make substitution errors on verbs inconsistent with that perspective.  相似文献

The present paper is a commentary on an article by Drew Leder [1]. Leder identifies a series of texts in the clinical encounter, emphasizes the central role of interpretation in making sense of each of these texts, and articulates ordering principles to guide the interpretive work.The metaphor of clinical work as textual explication, however, creates the expectation that there is a text somewhere to be found. Such an expectation invites doctors and patients to search for the text and runs the risk of conceptualizing patients as more static than they are. If one is to use the textual metaphor, one must appreciate the radical extent to which the clinical encounter is a mutually produced and shifting entity. The qualities of mutuality and indeterminacy are not those one usually associates with texts. One might ultimately be better served by a different metaphor based more directly on uncertainty.  相似文献

Attention Deficit Hyperactivity Disorder (ADHD) is a common and impairing neuropsychiatric disorder with onset at preschool age. Although a significant amount of progress has been made investigating the neurobiology of this disorder, its precise etiology still remains unclear. Converging evidence from studies of the neuropharmacology, genetics, neuropsychology, and neuroimaging of ADHD imply the involvement of fronto-striatal circuitry in ADHD. However, while it does appear that poor inhibitory control and the deficits in fronto-striatal circuitry associated with it are central, there is evidence to suggest that more posterior cerebral areas are also implicated in this disorder. Anatomical studies suggest widespread reductions in volume throughout the cerebrum and cerebellum, while functional imaging studies suggest that affected individuals activate more diffuse areas than controls during the performance of cognitive tasks. The future impact of new MR imaging methodologies on the field is discussed.  相似文献

A wide variety of nonestablished treatments have been proposed as "cures" for the core features of autism and are used frequently despite having largely escaped scientific scrutiny. In contrast, a growing body of empirical evidence supports the use of a few forms of theory-based and empirically validated treatment for some aspects of the core features of autism. These include behavioral/psychoeducational interventions and specific forms of medication treatment, which can produce significant improvements in communication, social interaction, and problem behaviors that both maintain over time and generalize across settings. While there is no doubt that treatment and educational services for persons with autism have improved over the past 6 decades, it also appears that significant issues remain with respect to (1) the routine application of validated treatments for the majority of cases with autism, (2) the resistance to even validated forms of treatment for a substantial minority of cases with autism, and (3) the extent to which validated treatments effectively treat the specific core features of autism that are most disabling for persons with autism and their families.  相似文献
