The use of linguistic abstraction in self‐presentation was examined. Participants, whose goal it was to be liked by recipients, presented their political views to an audience of two people. Participants learned beforehand that the two recipients had the same political views as the participant, that both had different political views from the participant, or that one had similar views to and one had dissimilar views from the participant. Theorising that variations in the degree of linguistic abstractness used by participants when describing their political views were related to their social goals, it was hypothesised that participants would describe their political views at a higher level of linguistic abstractness when communicating with a similar agreeing audience than when communicating with a mixed audience. Results confirmed this hypothesis. The role of linguistic abstractness in achieving self‐presentational goals is discussed. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Two challenges are posed for social scientists, one substantive and the other disciplinary. First, scholars and practitioners should together find ways to transform fragmented and conflictual relationships into relationships capable of building peaceful societies where human dignity is respected. Second, to achieve this goal, they should work to develop non-disciplinary spaces where people from different disciplines can come together to create the requisite conceptual and methodological frameworks.  相似文献

This investigation extends the constant time delay research base by embedding nontargeted information in the task direction when teaching communication skills. Specifically, instructors taught receptive identification of packaged food items to 4 secondary students with moderate to severe disabilities and evaluated generalization to the community. In addition, instructors included the manual sign for each food item. The instructional strategy was a constant time delay procedure using a 5-s delay interval. The intervention, conducted within a multiple probe design across behaviors replicated across students, resulted in the acquisition and generalization of receptive identification of packaged food items by 3 out of 4 of the students. In addition, the students acquired the nontargeted manual signs with an average of 60% percent in the final probe session.  相似文献

Abstract. Resolution of the entropy‐evolution problem was a significant issue for Pierre Teilhard de Chardin throughout his scientific career. Although never truly satisfied with his solution, he proposed that all energy must be psychic and contain two components. Tangential energy is related to physical energy. Radial energy in some way accounts for increasing complexity and consciousness in evolution. Analysis of developments in thermodynamics, statistical mechanics, and information theory show that Gibbs free energy contains both calorimetric and noetic components, thus validating Teilhard's intuition.  相似文献

The purposes of this study were to identify a zone of normality based upon ratings of perceived exertion (RPE) and compare the RPE of women with coronary artery disease to this zone. 45 healthy women (34.8 +/- 9.1 yr.) completed a Bruce treadmill test. RPE were estimated during the last minute of each workload. The zone of normality was established as the 95% confidence interval spanning the average line when RPE was regressed against MET. 51 women (66.6 +/- 9.3 yr.) with coronary artery disease completed a symptom-limited treadmill test. 31 of the women with coronary artery disease were taking beta blockers. RPE were compared to the RPE/MET relation of the zone. 57% of the women with coronary artery disease estimated RPE above the zone during the treadmill test. RPE responses above the zone of normality indicate an elevated perceptual strain for a given energy expenditure (i.e., MET). The zone of normality might be used as an aid in discriminating between normal and abnormal RPE responses during graded treadmill tests by women with coronary artery disease.  相似文献

In typical dual‐task driving studies, participants concurrently perform pairs of driving‐related and ‐unrelated tasks (e.g. vehicle braking and mental arithmetic). Requiring responses to both may implicitly equate their importance. In real‐life driving, however, the potential for collision dictates that a concurrent task should be assigned far lower priority than driving. To better reflect naturalistic driving conditions, we not only instructed participants to assign maximum priority to braking in a simulated driving task, but also encouraged them to ignore the concurrent task altogether on dual‐task trials. Despite these instructions, responses to the concurrent task often preceded braking, which suffered from dual‐task interference. We also found that redundant signals to the lead vehicle's brake lights resulted in faster braking responses and an increased likelihood that the braking response would occur first. The results are consistent with the Central Bottleneck (CB) model of dual‐task interference and may help guide the design of driver‐assistance systems.

The present study proposes and tests a model that examines the relationship between leadership style, trust, employee interpretations of managerial explanations, and justice perceptions. Using a critical incident methodology, 203 working adults were asked to recall a recent situation in which a request or proposal made to their manager was denied. Results provide strong support for the theoretical model. Namely, the effect of leadership style on explanation perceptions was indirect through employees' level of trust in their manager. Specifically, employees who felt their manager was transformational reported a higher degree of trust and more favourable reactions to managerial explanations.  相似文献

ABSTRACT— Childhood-onset antisocial behavior is an important predictor of chronic and serious forms of antisocial behavior in later life. Both biological and social factors are involved in the development of abnormal behavior. We examine the underlying role of stress-response systems in the link between early social adversity and juvenile antisocial behavior, and propose that children with genetically and/or perinatally based neurobiological deficits have problems in activating these systems and therefore experience difficulties in regulating affect and behavior. Underactivity or attenuated reactivity of the stress-response systems may predispose antisocial individuals to seek out stimulation or take risks, and thereby explain deficits in learning and socialization. Further investigations of neurobiological functioning in antisocial children might not only indicate which children are more likely to persist in behaving antisocially but also guide the development of new interventions.  相似文献

Using the telephone to contact others can be an important skill in maintaining friendships with peers. This investigation used a system of least prompts (SLP) procedures to teach two telephone skills to 3 elementary students with cognitive disabilities: (a) placing phone calls and (b) leaving recorded voicemail messages. The SLP procedure was effective in teaching both skills to all 3 students. Results for maintenance and generalization, however, were mixed. This investigation was completed to partially satisfy the thesis requirement for a Master’s degree at the University of Kentucky.  相似文献
