Donald A. Dewsbury 《Aggressive behavior》1983,9(3):207-215
Social behavior, aggression, and copulation were studied in six groups of two males and two females each in seven species of muroid rodents (Clethrionomys gapperi, Microtus montanus, M ochrogaster, M pennsylvanicus, Peromyscus eremicus, P leucopus, and P polionotus) in a seminatural enclosure. Data were compared to those from an earlier study with P maniculatus tested under identical conditions. There were appreciable species differences in levels of both aggressive and sexual behavior; the two were not significantly correlated. Although levels of aggression did not appear well correlated with reports of social structure in the field, patterns of weight loss and litter production during the study did appear correlated. In general, levels of copulatory behavior appeared weakly correlated with factors previously proposed as predictors of polygamous mating systems; levels of aggressive behavior were better correlated with taxonomy. 相似文献

The term “aggression” has been used to describe practically all situations in which an organism threatens, damages, or kills another-with the exception of certain predator-prey relationships. As a result, a great deal of confusion and controversy has arisen as to the causal factors and functions of aggression. The main ethological hypotheses concerning the nature of aggression are put forward. In order to illustrate the divergence in causal factors and functions, differences in motivational, physiological, and ecological bases of aggression in two closely related fish species are described. A basic division of aggression into “self-defensive” and “property-protective” behavior is suggested, together with the parameters separating these categories on behavioral, causal, and functional bases. Mechanisms which enable motivational changes from one category to another to take place during a single encounter are discussed, these being pain stimuli and physical or psychological “cornering.” The importance of learning effects on fighting behavior are emphasized, especially their negative and positive reinforcing effects in relation to self and property defense. The biological significance of aggressive conditioning for the animal and the role of aggression in species maintenance are discussed. 相似文献

Male intruder rats were placed individually into the cage of an established resident on 2 occasions separated by a 7–8 day interval. Residents readily attacked intruders and both animals lost weight during the first encounter. In contrast, no serious fighting occurred on the second encounter, and both intruders and residents maintained their body weight during the 24-hr test. Observation of the intruder's behavior during the first 30 min of each encounter indicated that defensive-submissive postures represent a response to an attack that only temporarily inhibits aggression whereas the emission of 22 kHz calls by the intruder is associated with a relatively permanent decrease in the resident animal's aggressive response. 相似文献

In three studies, Resource Holding Power (RHP) and provocation were manipulated in scenarios involving a young person in a bar with friends. In Study 1, teenage men reported lower likelihood of responding with physical aggression when insulted as levels of three RHP cues (size, allies and reputation) increased, effects that were accentuated by combinations of high-RHP cues; in the second part of this study, they consistently rated an insult to their girlfriend as the most provoking from a range of possible provocations, chosen on theoretical and empirical grounds. Study 2 replicated the results of the first part of Study 1 in samples of men and women in their twenties, although the effects were weaker at low levels of RHP. Study 3 combined a high- or low-provoking event, with low, medium or high RHP, and a wider range of response choices. As expected, direct aggression increased as provocation increased and RHP decreased. Delayed aggressive responses, including revenge fantasies, were highest in response to high provocation and high RHP. Findings are discussed in relation to theoretical models of aggressive motivation. 相似文献

医院积极处理医疗投诉的意义与实施方法 总被引:1,自引:0,他引:1

医疗投诉往往是医疗纠纷的雏形,消极处理可能使矛盾激化,让医院和患者成为对立的双方,由此增加了问题解决的难度和成本。医院积极对待处理医疗投诉具有积极意义,在降低投诉处理难度和成本的同时,也很好的塑造了医院的社会形象。同时阐述了其积极应对的措施。 相似文献

As aggressive behavior has a negative impact in general psychiatry, its influence specifically from a gender-related point of view in an in-patient population of a psychiatric clinic was assessed at the time of admission. A group of 521 successively admitted psychiatric in-patients was investigated at admission with the help of the "Social Dysfunction and Aggression Scale". A slightly higher frequency and intensity of "verbal aggressive behavior" was observed in males. Within the other categories of aggressive behavior ("tension", "physical violence to things", and "assaults"), however, the percentages and intensities of gender-related aggressive behavior did not differ significantly. Furthermore, under the covarying impact of various psychiatric diagnoses, the gender-related differences concerning the intensity of "verbal aggressive behavior" disappeared. When comparing male and female subgroups, it was notable that male schizophrenic patients were younger than female patients when displaying comparable risks of showing at least one kind of aggressive behavior. In addition, in the female subgroup, "self-injurious behavior" was more strongly correlated to the category "tension" than in the male subgroup. Although there are some methodological shortcomings, the present results show that there are small qualitative differences in gender-related aggressive behavior in addition to minimal quantitative differences in the frequency and intensity of "verbal aggressive behavior" at admission. 相似文献

执行功能与攻击行为关系的研究 总被引:3,自引:1,他引:2
攻击行为产生的原因十分复杂,受当今认知神经科学的影响,心理学研究人员从执行功能的角度来探讨攻击行为。现有的研究主要从心理学、流行病学、行为神经学、神经心理学和神经成像角度,考察和分析二者内在的关联,结果表明在暴力犯罪、反社会人格、杀人犯、精神病患者、少年犯、注意缺陷-多动障碍等群体,执行功能与攻击行为间存在很强的负向关联。将来的研究需要拓宽研究被试群体,深入考察内在的脑机制,制定恰当的攻击行为干预方法。 相似文献

班级行为范式对个体行为与受欺负关系影响的多层分析 总被引:3,自引:1,他引:3
运用同伴提名法、问卷法对82个班级4654名初中生的个体行为、朋友数量及学业成绩进行了测量,并用多层线性模型(HLM)对数据进行了分析处理。研究结果表明,在个体水平上,初中生的朋友数量和学业成绩对受欺负状况有明显的负向预测效果,初中生的攻击和退缩行为对受欺负状况有明显的正向预测效果。在班级水平上,班级的攻击行为范式可以减弱攻击行为和受欺负状况间的正向联系,增强退缩行为和受欺负状况间的正向关联;而班级的退缩行为范式则可以强化攻击和受欺负状况间的正向联系,弱化退缩行为与受欺负状况间的正向关联。 相似文献
