The effects of movement on unfamiliar face recognition were investigated. In an incidental learning task, faces were studied either as computer-animated (moving) displays or as a series of static images, with identical numbers of frames shown for each. The movements were either nonrigid transformations (changes in expression) or rigid rotations in depth (nodding or shaking). At test, participants saw either single, static images or moving sequences. Only one experiment showed a significant effect of study type, in favor of static instances. There was no additional advantage from studying faces in motion in these experiments, in which both study types showed the same amounts of information. Recognition memory was relatively unaffected by changes in expression between study and test. Effects of viewpoint change were large when expressive transformations had been studied but much smaller when rigid rotations in depth had been studied. The series of experiments did reveal a slight advantage for testing memory with moving compared with static faces, consistent with recent findings using familiar faces. Future work will need to examine whether such effects may also be due to the additional information provided by an animated sequence. 相似文献

Relative size judgments were collected for two objects at 30.5 m and 23.8 m from the observer in order to assess how performance depends on the relationship between the size of the objects and the eye level of the observer. In three experiments in an indoor hallway and in one experiment outdoors, accuracy was higher for objects in the neighborhood of eye level. We consider these results in the light of two hypotheses. One proposes that observers localize the horizon as a reference for judging relative size, and the other proposes that observers perceive the general neighborhood of the horizon and then employ a height-in-visual-field heuristic. The finding that relative size judgments are best around the horizon implies that information that is independent of distance perception is used in perceiving size. 相似文献

This study of 28 managers investigated the importance for mental health of Jahoda's (1982) five categories of experience, measured for both work and leisure. Each of the categories of experience of time structure, social contact, collective purpose, status, and activity correlated with at least one measure of mental health. Multiple regression analysis showed that collective purpose and status, in both work and leisure, had moderate to large β coefficients, indicative of their potential influence, for a range of measures of mental health, covering positive mental health and freedom from negative mental health. Analyses of Warr's (1987) nine "principal environmental influences" (PEI) also supported the importance of collective purpose and status. This showed that the PEI "valued social position," which includes these two categories of experience, remained significantly associated with several measures of mental health. Analysis of the PEIs also showed that opportunity for use of existing skills in leisure, and variety in leisure, were significantly associated with several measures of mental health. The importance of valued social position and active leisure for the well-being of managers is discussed. 相似文献

According to the embodied approach to visual perception, individuals scale the environment to their bodies. This approach
highlights the central role of the body for immediate, situated action. The present experiments addressed whether body scaling—specifically,
eye-height scaling—occurs in memory when action is not immediate. Participants viewed standard targets that were either the
same height as, taller than, or shorter than themselves. Participants then viewed a comparison target and judged whether the
comparison was taller or shorter than the standard target. Participants were most accurate when the standard target height
matched their own heights, taking into account postural changes. Participants were biased to underestimate standard target
height, in general, and to push standard target height away from their own heights. These results are consistent with the
literature on eye-height scaling in visual perception and suggest that body scaling is not only a useful metric for perception
and action, but is also preserved in memory. 相似文献

Here, we demonstrate that the decision to conform to another person’s memory involves a strategic trade-off that balances
the accuracy of one’s own memory against that of another person. We showed participants three household scenes, one for 30 s,
one for 60 s, and one for 120 s. Half were told that they would encode each scene for half as long as their virtual partner,
and half were told that they would encode each scene for twice as long as their virtual partner. On a subsequent two-alternative-forced
choice (2AFC) memory test, the simulated answer of the partner (accurate, errant, or no response) was shown before participants
responded. Conformity to the partner’s responses was significantly enhanced for the 30-s versus the 60- and 120-s scenes.
This pattern, however, was present only in the group who believed that they had encoded each scene for half as long as their
partner, even though the short-duration scene had the lowest baseline 2AFC accuracy in both groups and was also subjectively
rated as the least memorable by both groups. Our reliance on other people’s memory is therefore dynamically and strategically
adjusted according to knowledge of the conditions under which we and other people have acquired different memories. 相似文献

BackgroundNarrative therapy (White & Epston, 1990) was developed as an approach to counselling, as a response to the power relations that influence people's lives. Its use with people who stutter has been documented. A basic tenet of narrative therapy is that the dominant problem-saturated narrative is challenged by externalizing the problem, in due course facilitating development of an alternative narrative. Within this process, the definitional ceremony involving outsider witnesses is a key procedure used to influence change.AimsThis paper describes definitional ceremonies, and their application within a narrative approach to therapy for stuttering. The analysis of a specific definitional ceremony is presented, leading to an exploration of identity as a public and social achievement.MethodsA definitional ceremony involving a woman who stutters and family members was recorded and analysed using two methods: interpretative phenomenological analysis and Heideggerian hermeneutic phenomenological analysis. Details of the clinical application of definitional ceremonies with this client are described.Results and conclusionsResults from both methods of analysis were found to be similar. Notable results include the fact that the stuttering per se was not presented as the problem; rather, the impact of stuttering, especially the experience of bullying, was a dominant theme. This paper shows how definitional ceremonies can open opportunities for clients to present themselves in a preferred way, forming the basis for a new story and revised identity. Emerging themes can be identified for reflection and discussion with the client for therapeutic benefit.Educational objectives: (1) to describe and explain to readers the process of narrative therapy, with special attention to the use of definitional ceremonies; (2) to provide detail regarding the clinical processes involved with a specific definitional ceremony with one client; (3) to have the reader appreciate the specific importance of involving outsider witnesses in the therapy process; (4) to discuss the outcomes of the use of this particular definitional ceremony. 相似文献

Although both auditory and visual information can influence the perceived emotion of an individual, how these modalities contribute to the perceived emotion of a crowd of characters was hitherto unknown. Here, we manipulated the ambiguity of the emotion of either a visual or auditory crowd of characters by varying the proportions of characters expressing one of two emotional states. Using an intersensory bias paradigm, unambiguous emotional information from an unattended modality was presented while participants determined the emotion of a crowd in an attended, but different, modality. We found that emotional information in an unattended modality can disambiguate the perceived emotion of a crowd. Moreover, the size of the crowd had little effect on these crossmodal influences. The role of audiovisual information appears to be similar in perceiving emotion from individuals or crowds. Our findings provide novel insights into the role of multisensory influences on the perception of social information from crowds of individuals. 相似文献
