Metaphors are pervasive in both mass communication and interpersonal exchanges and can play an important role in persuasion. Metaphor serves multiple functions in persuasive communication, and the effect of metaphor on persuasion is potentially mediated by multiple psychological process mechanisms. Nevertheless, we propose that past and future research in this area can be organized or grouped into three simple categories. First, metaphorical statements can activate information that is directly applied to the communication topic and thereby influence attitudes toward the communication topic. Second, metaphorical language may influence impressions of the communication source and thereby impact attitudes toward the communication topic. Third, metaphors may affect attitudes toward the communication topic by influencing the direction or amount of elaboration that takes place when recipients process literal statements contained in the communication. A review of past research is organized into these three categories, and proposals for future research in each category are introduced. It is concluded that future research within each of these domains should focus on two related questions: under what conditions does metaphor elicit a given psychological process in the receiver (e.g., attribute mapping, valence transfer), and under what conditions will a given process result in an increase versus decrease in persuasion? 相似文献
This study examined the relationship between group conflict management styles and effectiveness of group decision making in 11 ongoing, naturally occurring workgroups from 2 large U.S. organizations. The major postulate of the study was that groups develop norms regarding how they will manage conflicts that carry over to affect other activities, such as decision making, even when these activities do not involve open conflict. To determine the impact of conflict management style on decision effectiveness, a longitudinal design was used that identified conflict management styles in the initial portion of each team's series of meetings and then analyzed a group decision taken in a meeting near the end of that series. Group conflict management styles were determined using observational methods, and decision effectiveness was measured using multiple indices that tapped member, facilitator, and external observer viewpoints. Task complexity also was considered as a possible moderating variable. The findings suggest that groups that developed integrative conflict management styles made more effective decisions than groups that utilized confrontation and avoidance styles. Groups that never developed a stable style were also less effective than groups with integrative styles. 相似文献
Observers viewed the optical flow field of a rotating quadric surface patch and were required to match its perceived structure by adjusting the shape of a stereoscopically presented surface. In Experiment 1, the flow fields included rigid object rotations and constant flow fields with patterns of image acceleration that had no possible rigid interpretation. In performing their matches, observers had independent control of two parameters that determined the surface shape. One of these, called the shape characteristic, is defined as the ratio of the two principle curvatures and is independent of object size. The other, called curvedness, is defined as the sum of the squared principle curvatures and depends on the size of the object. Adjustments of shape characteristic were almost perfectly accurate for both motion conditions. Adjustments of curvedness, on the other hand, were systematically overestimated and were not highly correlated with the simulated curvedness of the depicted surface patch. In Experiment 2, the same flow fields were masked with a global pattern of curl, divergence, or shear, which disrupted the first-order spatial derivatives of the image velocity field, while leaving the second-order spatial derivatives invariant. The addition of these masks had only negligible effects on observers’ performance. These findings suggest that observers’ judgments of three-dimensional surface shape from motion are primarily determined by the second-order spatial derivatives of the instantaneous field of image displacements. 相似文献
Using gray-white metric patterns, for which figure-ground relationships had been previously determined, several features of an attentional theory of brightness contrast were investigated. Experiment I, involving three subjects and the method of constant stimuli, showed that ground, the unattended area, could be reliably perceived as brighter; responses were affected by both the type of pattern and level of contrast ratio. Experiment II, involving 40 subjects and the method of magnitude estimation, used metric patterns for which attentional factors were not confounded with relative area. The results supported the first study and further indicated the primary involvement of relative area rather than focus of attention in brightness contrast.
With an endless range of subgroups and individual variations, culture bears upon what all people bring to the clinical setting. Culture could account for health-seeking behaviour, type of services and support system and variations in how people communicate their health concerns. Culture may underlie presentation of sets of symptoms that are peculiar to certain societies – culture-bound syndromes. Culture also influences the meanings that people impart to their illness and also stigma associated with such illnesses. Culture must be viewed from the patients, clinicians and health system dimensions. Changes in mental health service delivery in last few decades have yielded culturally competent mental health services. The aim of this paper was to discuss culture and mental health with a focus on Nigeria and from a global perspective. 相似文献
The field of affective clinical science has expanded dramatically over the past several decades (Rottenberg and Gross 2003; Tracy et al. 2014). An important part of this research is understanding emotion regulation and dysregulation, in particular, how individuals differ in their ability to identify, accept, and manage their emotional experiences. One of the most common and widely cited measures of emotion dysregulation is the Difficulties with Emotion Regulation Scale (DERS; Gratz and Roemer 2004), which has been extensively used to facilitate understanding of how emotion dysregulation is associated with psychiatric symptoms, other emotion-related constructs, and treatment progress. While this scale has contributed greatly to our understanding of emotion regulation problems, its length makes its inclusion in brief study protocols difficult, limiting its utility and increasing participant burden. In order to address this issue, we developed a short form version of the DERS (DERS-18) composed of the strongest items from each of the measure’s six subscales from the original DERS publication (Gratz and Roemer 2004), and then validated this measure in five datasets that vary in age and sample type. Our results demonstrate that an 18-item short-form of the DERS exhibits a similar structure as the original 36-item DERS, demonstrates excellent reliability and validity, and performs similarly to the original DERS despite comprising half the items. The DERS-18 has the potential to improve and expand emotion regulation assessment while reducing demands on research participants. 相似文献
