K. A. Mitchell 《Aggressive behavior》1976,2(1):31-37
The aggressive behavior of large Clibanarius vittatus against small C. vittatus was investigated. Large C. vittatus were more aggressive and showed fewer fear reactions in all conditions tested. The degree of dominance of large over small C. vittatus was much more marked and more predictable when the smaller crab occupied a Polinices rather than a Littorina shell and the large crab occupied a Littorina shell in both conditions. Evidence is given to suggest that C. vittatus reacts more to the shape than the size dimensions of a Polinices shell, and that small crabs occupying a Polinices shell are less active than other crabs occupying a Littorina shell. 相似文献

Aspects of the social pecking of domestic chicks in a free response situation were examined in a series of experiments. It was proposed that a dual pattern of responses involving (a) a preponderance of pecks at the head of a conspecific, and (b) heightened emotionality (as indicated by the emission of distress calls) might be taken to reflect an aggressive tendency, and evidence was reviewed that showed that a brief period of isolation was a sufficient condition to elicit such a pattern. The main questions asked in this paper are: (a) whether the gender of a chick had a material influence on the incidence of such social pecking, and (b) whether orders established in pecking exchanges reflected a unidimensional social ordering among chicks. In the 1st set of studies the effect of the sex of subject on rates of social pecking was tested. While an isolation procedure clearly produced the dual pattern of heightened head pecking and calling, reliable sex differences were not in evidence. In a 2nd study, concerned with the generality of social orders as observed in social pecking exchanges, the isolation procedure again was sufficient to produce apparently aggressive reactions but the resulting peck orders between chicks did not predict success in later tests when the same 2 subjects were pitted against one another in either approach or avoidance competitive tasks. These results are discussed in terms of the relationship of infant aggression to adult aggression, and suggestions are made for a revised view of the development of the aggressive behavior of fowl. 相似文献

对竞和的现代从商之道进行企业伦理解读,我们不难发现,企业如果以竞和为自己的从商之道,必能形成一幅企业内部和谐、外部和顺、整体协调以及企业与整个社会义利共生的和谐图景。而这种义利共生的和谐图景,带给企业和社会的也不只是遵循企业伦理原则之义,还有和实生物、和气生财、和能致祥以及和成天下之利。 相似文献

研究包含两个实验,均采用反应时测量的方法。第一个实验考查并验证了阈下情绪启动效应衰退的现象;第二个实验的结果则支持反应时指标测量情绪启动效应发生机制的反应竞争的观点,并提出阈下情绪启动效应的内在机制模型。文章最后用反应竞争的观点对第一个实验中的现象进行了解释,提示内隐学习可能在效应衰退现象中发挥作用。 相似文献

Persistence is an important predictor of future successes. The present research addresses the relationship between testosterone and persistence in men. One hundred eighteen men were randomly assigned to win or lose a competitive number tracing task against a confederate or complete the task alone in a non‐competitive control condition. Saliva samples were collected prior to and after the competition or control conditions. Participants were then given a maximum time of 30 min to spend attempting to solve unsolvable puzzles, with the option to quit at any time. In contrast to our prediction, changes in testosterone concentrations in response to the competitive interaction did not predict persistence behaviour. However, individual differences in testosterone concentrations (pre‐competition/non‐competition) were positively correlated with persistence. These findings are the first to examine associations between neuroendocrine function and persistence behaviour in people and suggest that testosterone should also be considered when predicting persistence‐related outcomes.

In interactive decisions, cues to what others will do are important in forming a strategy. Information about others' personalities appears to be potentially valuable for this purpose. We report a series of four studies examining how information about another actor's personality influences people's own choices in interactive decisions. The studies found widespread beliefs that others' personality characteristics are strongly predictive both of broad classes of decision behavior (competition/cooperation, risk‐seeking/risk‐aversion) (Study 1) and of specific choices (Study 2) in single‐agent settings. These beliefs extended to predicting others' choices in interactive decisions (Study 3) and to shaping the predictor's own decisions in interactive play in Chicken and Assurance games (Study 4). Overall, we found extensive evidence that laypeople believe that the personality traits we selected (angry‐hostility, anxiety, assertiveness, excitement‐seeking, and warmth) have substantial effects on behavior in interactive decisions and they act on those beliefs when making their own decisions. The empirical evidence supporting the predictive validity of these traits was, however, quite weak. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

In many cases, the formation of intermediate phases in solid-state reaction starts from nucleation, proceeds at first by lateral spreading along interface in the form of narrow layer and after that continues slow growth in normal direction. So far, the lateral growth stage was considered as something almost instant. Yet, if the emerging phase is not the first one and the already growing phase layer has high diffusivity, the lateral growth can be also kinetically suppressed due to ‘sucking out’ of atoms from the moving interface into the growing first phase layer. Criteria of such suppression are formulated and examples of real systems are discussed. 相似文献

Machiavellianism is characterized by a manipulative interpersonal style and willingness to exploit others (Christie & Geis, 1970). Though previous research has focused on the influence of Machiavellianism in short‐term relationships, Machiavellianism may also influence behavior within long‐term committed romantic relationships. Heterosexual men (N = 93) and women (N = 141) in current romantic relationships of at least 12 months duration were recruited online. Participants completed Machiavellianism, Intra‐Sexual Competition, Mate Retention and Sexual Coercion scales. Regression analyses revealed that those with high levels of Machiavellianism were more likely to compete with same‐sex rivals, directly guard a mate and employ inter‐sexual or intra‐sexual negative inducements as a form of mate retention than those with low levels of the personality trait. Gender did not moderate the influence of Machiavellianism on these behaviors. Findings highlight the influence of Machiavellianism within long‐term committed romantic relationships. 相似文献

ObjectivesThis research explored whether several subgroups of athletes representing distinct emotional trajectories could be shown to exist within the latent class growth analysis (LCGA) of pleasant and unpleasant sport emotions (anger, anxiety, dejection, excitement, happiness). A secondary aim was to explore whether athletes belonging to distinct emotional trajectories reported distinct scores of trait-emotional intelligence (EI) at time 1 (T1).DesignA longitudinal three-wave measurement design (beginning, middle, and end of a competitive season) was used in the present study.MethodA sample of 460 athletes completed the sport emotion questionnaire across three measurement times and the brief emotional intelligence scale at T1.ResultsResults of LCGAs showed five trajectories for anger, anxiety and happiness, and six trajectories for dejection and excitement. Furthermore, athletes belonging to distinct (adaptive or maladaptive) trajectories reported significantly different scores of EI.ConclusionsLCGA results highlighted the athlete heterogeneity in longitudinal sport emotions. Higher scores of EI were reported by athletes belonging to adaptive emotional trajectories. These results could be used to help coaches and sport psychologists to identify athletes at risk of developing dysfunctional emotional trajectories across the competitive season. Moreover, this study suggested potential benefits of EI-centred interventions to help athletes to experience adaptive emotional trajectories. Finally, these results highlighted that heterogeneity in sport emotions must be accounted for in future research. 相似文献
