类属性思维(stereotypes)在一定的程度上是对群体区别正确反映的类属信仰.类属性思维比我们一般假想的更为复杂.首先,我们在本论文中探讨了在立体性的类属性思维EPA理论框架之下的多维度,即类属性思维的三维度:评估、激活和准确度.同时还特别讨论了类属性思维与具体集体共识的表征特点的图腾信仰之间的密切关系.其次,对于作为人类信仰一部分的类属性思维准确性莫衷一是的研究,我们进行了全面综述,并且本文还仔细考查文化类属性思维,个体类属性思维,个体与群体的判断,准确性评判的标准,和原分析的数据等等,同时进一步表明类属性思维和客观现实性有密不可分的关系.最后,我们指出类属性思维对解释群体和民族的区别非常重要,特别是人的感知的实质性寓于实在的客观群体本身(“感知的同一性”).我们认为,类属性思维的过程,对于高度的实体性和感知的实质性的群体来说,具有深刻影响,况且群体或部落(民族)的图腾也是其群体或民族的实体性的外在表现.尽管我们不可能解决同类属性思维的过程有关的所有争论,但我们所强调的观点是:类属性思维是人类相互影响和生存的有效类属性识别. 相似文献

Fifty-three national level cyclists completed competitive rides under both laboratory and field conditions to investigate the relationship between pre-competition anxiety and performance. A total of 39 males and 14 females participated in the study, ranging in age from 19 to 26. The objectives of the study were to, (a) measure the relationship between state anxiety and performance, (b) investigate differences in the anxiety-performance relationship under laboratory versus field conditions, and (c) examine the effect of trait anxiety on the state anxiety-performance relationship. State anxiety was measured using the Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Vealey, & Burton, 1990), and trait anxiety with the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, & Lushene, 1970). Results indicated that anxiety was strongly correlated with performance on the field test, but that the anxiety-performance relationship was weaker under laboratory conditions. Results also showed that trait anxiety interacted with the relationship, as low and high trait-anxious subjects had differential response patterns to pre-competition anxiety. The findings are discussed in terms of their relevance for both practitioners and researchers. 相似文献

Dental anxiety is a complicated phenomenon, and its multicomponent nature is often not acknowledged in existing measurement instruments. Using a facet design, a new Dental Anxiety Inventory (DAI) was constructed. Facets chosen were: time (made up of four elements: at home, on your way to the denstist, in the denstist's waiting room, in the dental chair), situation (three elements: introductory aspects, dentist-patient interaction, actual dental treatment), and reaction (three elements: subjective feelings, physical reactions, cognitive reactions). Psychometric qualities of the DAI are good. The internal structure of the DAI was studied by linear and nonlinear techniques, and was partially recovered from the data. The construct and criterion validity of the DAI was supported in several studies. 相似文献

Background and objectives: Terrorism can heighten fears and undermine the feeling of safety. Little is known, however, about the factors that influence threat and safety perception after terrorism. The aim of the present study was to explore how proximity to terror and posttraumatic stress reactions are associated with perceived threat and safety after a workplace terrorist attack. Design and methods: A cross-sectional questionnaire survey was administered to employees in 14 of 17 Norwegian ministries 9–10 months after the 2011 bombing of the government headquarters in Oslo (n = 3520). Results: About 198 of 1881 employees completing the survey were at work when the bomb exploded. Regression analysis showed that this high-exposed group had elevated perceived threat (β = 0.36; 95% CI = 0.19 to 0.53) and reduced perceived safety (β = ?0.42; 95% CI = ?0.62 to ?0.23) compared to a reference group of employees not at work. After adjusting for posttraumatic stress reactions, however, proximity to the explosion no longer mattered, whereas posttraumatic stress was associated with both high perceived threat (β = 0.55; 95% CI = 0.48 to 0.63) and low perceived safety (β = ?0.71; 95% CI, ?0.80 to ?0.63). Conclusion: Terror-exposed employees feel more threatened and less safe after a workplace terrorist attack, and this is closely linked to elevated levels of posttraumatic stress reactions. 相似文献

Our target article proposed an alternative perspective for studying consumer judgment and decision making, focusing on the types and weights of comparisons consumers select. In this response we consider the major points made by each of the commentators and examine their implications for future work addressing our comparison-focused approach. 相似文献

Abstract Although many studies have examined the nature of memory distortions in anxious individuals, few have considered biases in specific memory processes, such as encoding or retrieval. To investigate whether the presentation of threat material facilitates encoding biases, spider fearful (n=63), blood fearful (n=73), and nonfearful (n=75) participants encoded spider related, blood related, and neutral words as a function of three levels of processing (i.e., structural, semantic, and self referent). Participants subsequently completed either a free recall or a recognition task. All participants demonstrated a partial depth of processing effect, such that they recalled more words encoded in the self referent condition than in the other two conditions, but groups did not differ in their recall of stimuli as a function of word type. Relative to participants in the other groups, spider fearful participants had fewer spider related intrusions in the recall condition, and they made fewer errors in responding to structural and semantic encoding questions when spider related words were presented. These results contribute to an increasingly large body of literature suggesting that anxious individuals are not characterized by a memory bias toward threat, and they raise the possibility that individuals with spider fears process threat-relevant information differently than individuals with blood fears. 相似文献

Abstract The purpose of this study was to determine the association between the occurrence of stressful life events and internalizing and externalizing problems, and to analyze longitudinally buffering effects of supportive family relationships. To this end, 100 Spanish adolescents were studied twice, when they were in mid-adolescence (15–16 years) and two years later. They completed questionnaires regarding stressful life events, family relationships, and adolescent adjustment. Results showed that high quality parent-adolescent relationships protected boys and girls against the negative consequences of stressful life events on externalizing, but not internalizing, symptoms. The adolescents who enjoyed good relationships with their parents in mid-adolescence did not increase their externalizing problems in late adolescence as consequence of the occurrence of stressful events. However, these stressors did lead to an increase in the number of externalizing problems when the family relationships were of a middle or low quality. These results highlight the important role that supportive family relationships play in the behavioral adjustment of adolescents, protecting them against some negative consequences of stressful life events, and suggest the relevance of supporting parents through resources such as parent education in order to help them to improve their relationships with their adolescents. 相似文献

Few studies have attempted to explain ethnic differences in female aggression. The degree to which ethnic differences exist in the influence of parents' approval of aggression on their preadolescent daughters' use of physical, verbal, and relational aggression was explored in a sample of 97 parent-child dyads. Results indicate that European American parents were more disapproving of their daughters' aggressive behavior than were African American parents. Parents' attitude toward aggression was predictive of European American girls' use of physical and verbal aggression and African American girls' use of relational aggression. Implications for aggression prevention and intervention for girls are discussed. 相似文献

Researchers and workplace violence experts have cited risk factors that theoretically increase the likelihood that individuals will experience workplace violence. Those include working alone, contact with the public, traveling to dangerous areas, as well as other factors. By the very nature of what social services workers do, many encounter these risk factors on a regular basis. Using national data, trends in workplace violence experienced by social services workers are examined, and comparisons are made between the rates of workplace violence among similar workgroups. Results suggest that social services workers are nearly six times more likely than other workers to experience workplace violence. In the discussion, attention is given to strategies to prevent violence against social services workers. 相似文献
