Subjects adjusted the sound pressure level of a 1,000-Hz tone or the luminance of a 10° target on a translucent screen to match their anticipated subjective tension in performing before audiences represented by 1–16 color slides of old or young males or females. Consistent with a new theory of social impact, “tension” was a multiplicative power function of the number texponent ≅ .6) of people in the audience and their ages, with older t37-year-old) audiences generating 2–3 times the tension of younger Iteen-age) audiences. Male audiences elicited 50%-40% more tension than females. 相似文献

A forced-choice detection paradigm controlling for postperceptual inference was used to investigate letter identification in three-position displays. Letters from a predesignated set of four targets appeared singly, in strings of noise characters, in unpronounceable nonsense strings, and in words. Subjects knew which context would occur, but did not know which of the three display positions would contain the target. Correct detection data were collected at constant exposure duration over five testing sessions. Overall identification accuracy was higher in words than in all other contexts, the first word superiority effect to be found with targets specified in advance since Reicher’s (1969). This effect remained constant over sessions. An interaction between context type and target position showed enhanced accuracy for initial and terminal letters in words, but depressed accuracy at initial and terminal positions in other contexts. This was interpreted to mean that prior knowledge of context is used to alter the dynamics of perceptual analysis. 相似文献

Two experiments examined the effect of changes in the visual surround upon the velocity of motion aftereffects. Experiment I showed that introduction or reintroduction of a patterned surround midway through the test period was sufficient to produce an increase in apparent velocity. However, a greater increase was observed when a patterned surround instead of a dark homogeneous surround had been used during the induction period. Experiment II demonstrated that luminance change was also sufficient to produce an increase in apparent velocity, although the extent of the increase was not as great as that produced through the use of the patterned surround in Experiment I. These results indicate that a change in stimulus surround is sufficient to produce an increase in the velocity of a motion aftereffect and that the extent of the increase is dependent upon the characteristics of both the induction and test surrounds. 相似文献

In order (1) to study the relationship between complexity and preference for slides of the physical environment and (2) to test the hypothesis that the content of slides (in particular, whether nature or urban) will influence preference, independent of the rated complexity, 88 Ss were asked to rate 56 slides, both for preference and for complexity. Based on dimensional analyses, a nature and an urban dimension were identified. Three major results were obtained: (1) Nature scenes were greatly preferred to urban scenes (p < .001). (2) Complexity predicted preference within the nature domain (r = .69) and within the urban domain (r = .78). (3) Complexity did not account for the preference for nature over urban slides; the greatly preferred nature slides were, in fact, judged on the average less complex than the urban slides. The possibility is raised that the domain-specific character of the preference/complexity relationship found in this study may be general; that is, it may not be a special property of environmentally generated arrays. 相似文献

Eighty-one managers read application materials arrayed in a 2 (impression management versus nonimpression management cover letter) x 2 (impression management versus nonimpression management resume) x 2 (high versus low self-monitor) design and completed a survey on their perceptions. Managers rated the impression management cover letter negatively on several perceptions but positively on self-confidence. They rated the impression management resume negatively almost across the board. Implications were discussed in terms of the apparently counterproductive role of impression management in the resume but a limited possible role in the cover letter. 相似文献

A coalition of human service agencies in one city used the Concerns Report Method of Basic Needs and Vital Services to obtain information on the concerns of their poverty clients. Results were disseminated to local decision makers of the United Way agency, city commission, and county commission during their annual budget deliberations. Two standard accounting methods were used to compare budget allocations to agencies serving low-income people before and after dissemination of the Concerns Report, to other items in the three budgets, and to allocations to similar agencies in a second city. Allocations to agencies serving those most in need in the experimental community grew 17% faster than the total budget, increased 3.96% in share of total budget, and gained 22% over other allocations following dissemination of the Concerns Report. 相似文献

Summary Recently, there has been considerable interest in whether information in iconic memory is stored in retinotopic or spatiotopic coordinates. The present experiment examined the issue using a masking paradigm. In one set of conditions, subjects maintained fixation while a row of four letters appeared for 19 ms, centered about three degrees to the right of fixation. After a 153 ms ISI, the letters were followed by a blank field (no mask), a mask in the same position as the letters, or a mask displaced three degrees to the right of the letters. In a second set of conditions, the stimuli were the same but subjects were asked to shift fixation from the fixation point to the middle of the letter row during the interval between the letters and the mask. Subjects' eye movements were monitored in all conditions. Accuracy of report for the letters was lowered only with the mask over the letters with the no-eye-movement conditions and in both masking conditions with the eye movements. The results suggest that the icon includes two components, one that is retinotopic and one that is spatiotopic. 相似文献

Humour has occasionally been regarded as a valuable tool in counselling and psychotherapy. The specific uses of humour and its potential as a coping tactic are rarely described. The therapeutic use of humour is accordingly examined in the light of reversal theory (Apter, 1982a). It is suggested that the use of humour needs to be related to the motivational task implicit in the therapeutic interaction. 相似文献
