Assessing the causal structure of function 总被引:3,自引:0,他引:3
Theories typically emphasize affordances or intentions as the primary determinant of an object's perceived function. The HIPE theory assumes that people integrate both into causal models that produce functional attributions. In these models, an object's physical structure and an agent's action specify an affordance jointly, constituting the immediate causes of a perceived function. The object's design history and an agent's goal in using it constitute distant causes. When specified fully, the immediate causes are sufficient for determining the perceived function--distant causes have no effect (the causal proximity principle). When the immediate causes are ambiguous or unknown, distant causes produce inferences about the immediate causes, thereby affecting functional attributions indirectly (the causal updating principle). Seven experiments supported HIPE's predictions. 相似文献

Phoneme identification with audiovisually discrepant stimuli is influenced hy information in the visual signal (the McGurk effect). Additionally, lexical status affects identification of auditorily presented phonemes. The present study tested for lexical influences on the McGurk effect. Participants identified phonemes in audiovisually discrepant stimuli in which lexical status of the auditory component and of a visually influenced percept was independently varied. Visually influenced (McGurk) responses were more frequent when they formed a word and when the auditory signal was a nonword (Experiment 1). Lexical effects were larger for slow than for fast responses (Experiment 2), as with auditory speech, and were replicated with stimuli matched on physical properties (Experiment 3). These results are consistent with models in which lexical processing of speech is modality independent. 相似文献

Erroneous knowledge of results (KR) that conflicts with other internal or external information sources is preferentially used and misguides performance on motor and mental timing tasks. Buekers et al. [J. Motor Behavior 26 (1994) 27] hypothesized that KR is used preferentially because participants deem it to be the most reliable information source. We tested this hypothesis in two experiments. We manipulated subjective reliability of information and information content and demonstrated that both reliability and content are assessed and used. In a third experiment we examined whether attributional style affected the use of internal and external information. While KR was present, attributional style was unrelated to performance. However, when erroneous KR was withdrawn, participants who scored high in internal attributional style or high in controllability showed more accurate performance. Whereas evaluation of information quality is explicit, information provided by the KR, whether accurate or not, may influence both implicit and explicit aspects of the tasks. 相似文献

The personality of exemplary young adults was studied in an effort to paint a portrait of moral excellence that expanded upon the traditional emphasis on moral reasoning maturity. These young adults were nominated based on their extraordinary moral commitment towards various social organizations. The sample included 40 moral exemplars and 40 matched comparison individuals who responded to a battery of questionnaires and participated in a semistructured interview. It was found that moral exemplars, in contrast to comparison individuals, were more agreeable, more advanced in their faith and moral reasoning development, further along in forming an adult identity, and more willing to enter into close relationships. These findings are discussed in the context of describing moral excellence from a multifaceted, personality perspective. 相似文献

This study examined which kinds of self-defining memories show spontaneous references to larger meanings, and listener responses to two kinds of meaning-lessons and insights. Narratives of three self-defining memories and episodes of telling the memories to others were collected from each of 168 late adolescents (M age=19). Narratives were coded for event type (relationship, mortality, achievement, and leisure) and for references to tension and to meaning (lesson or insight). Narratives of memorable episodes of having told the memories to others were coded for listener response (positive or negative). References to meaning emerged in one-fourth of the memory narratives, and meaning was more common for self-defining memory narratives that contained references to tension. Memories that reportedly had not been told to others in the past showed the same proportion of meaning as did memories that had been told to others (23%), with insights more prevalent than lessons. For memories that had been told to others, insights were more likely to be accepted by listeners than lessons. Implications were discussed for understanding the development of meaning in self-defining memories and the collaborative construction of identity. 相似文献

We describe a new, open flow device for presenting taste stimuli to human subjects under controlled conditions of timing. The device delivers each stimulus as a mist to the participant’s tongue through one of 16 nozzles attached to a linear slide. Software controls the position of the slide, the duration of the stimulus, and the duration of the pre- and poststimulus water rinses and records the responses of the participant. Temporal characteristics of this system make it especially applicable to studies on the role of attention in taste perception. 相似文献

This study is an empirical investigation of how 175 university students obtained their knowledge of sexual matters and whether pornography functioned as an important source. Analysis indicated that pornography does not play an important role in the dissemination of sexual information; peers appear to be the primary source. There are, however, certain statistically significant differences between the sexes in reports of the extent of specific sexual information from pornography on matters such as oral and anal intercourse. The findings extend research on pornography as a source of sex information and are contrasted with previous studies. 相似文献

Retrospection in social dilemmas: how thinking about the past affects future cooperation 总被引:2,自引:0,他引:2
This article reports 2 studies investigating the effects of retrospective thought on future cooperation in social dilemmas. Some general theories of cooperation presume, but have not tested, whether retrospection has impact: People may think about the choices they could have made instead, realize that cooperation would have produced larger outcomes, and change their strategy as a result. Across both studies, the authors show that rate of future cooperation is directly related to the number of best-case scenarios and inversely related to the number of worst-case scenarios generated. The 2nd study also shows that the number and type of retrospective thoughts generated can be predicted from the person's social value orientation. 相似文献

Asymmetric resting blood flow in prefrontal and hemispheric regions, assessed by single photon emission computed tomography (SPECT), was examined as a potential biological marker for enhanced trait and state anxiety in 30 older men (ages 55-81). Average and asymmetric perfusion in dorsolateral, medial, and orbital regions of the prefrontal lobes was also assessed. Results indicated a significant association between lower levels of resting dorsolateral blood flow and greater state anxiety responses to a series of stressful provocations (measured on a separate occasion). A significant curvilinear (U-shaped) relation between asymmetric dorsolateral perfusion and state anxiety was also identified; increased asymmetric blood flow favoring either the right or the left dorsolateral region related to higher levels of state anxiety. However, this association was attenuated by age and systolic blood pressure. Resting perfusion in the dorsolateral region may represent a more reliable biological marker for state anxiety than trait anxiety in older men. 相似文献
