A notable uptick of interest in the stability of self‐esteem has been observed over the past few years. Most researchers, however, have focused on unidimensional rather than multidimensional conceptualizations of self‐esteem. The paucity of empirical research is surprising given conflicting theoretical perspectives on the stability of self‐esteem. The goal of the present study was to thoroughly disentangle different conceptualizations of self‐esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self‐esteem. We analysed two‐year longitudinal data from participants (N = 644 at T1, N = 241 at T2) with an average age of 47.0 years (SD = 12.4). Analyses using a latent variable approach revealed that the domains of self‐esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self‐esteem. Results did not provide support for either top‐down or bottom‐up effects between domain‐specific and global self‐esteem. These findings have important theoretical and practical implications regarding the stability and development of self‐esteem in adulthood and advance the understanding of self‐esteem in personality theory. © 2018 European Association of Personality Psychology 相似文献

It has been suggested that the impact of emotional expressions on the startle reflex is influenced by the intention communicated by the expression (e.g., the intention to attack). However, we propose that the meaning of an emotional expression is not only based on the intention, but is also influenced by characteristics of the expresser such as gender: since men are typically seen as more dominant than women, anger expressed by men should be perceived as particularly threatening, thus amplifying the startle response. We compared the influence of anger, fear and neutral expressions shown by men and women on the startle reaction. Startle reactions were measured using electromyography. As predicted, we found stronger startle reactions after the presentation of anger expressed by men compared to fearful and neutral expressions shown by men. For female expressers, the startle response was not affected by expression type. 相似文献

Many everyday decisions have to be made under risk and can be interpreted as choices between gambles with different outcomes that are realized with specific probabilities. The underlying cognitive processes were investigated by testing six sets of hypotheses concerning choices, decision times, and information search derived from cumulative prospect theory, decision field theory, priority heuristic and parallel constraint satisfaction models. Our participants completed 40 decision tasks of two gambles with two non‐negative outcomes each. Information search was recorded using eye‐tracking technology. Results for choices, decision time, the amount of information searched for, fixation durations, the direction of the information search, and the distribution of fixations conflict with the prediction of the non‐compensatory priority heuristic and indicate that individuals use compensatory strategies. Choice proportions are well in line with the predictions of cumulative prospect theory. Process measures indicate that individuals thereby do not rely on deliberate calculations of weighted sums. Information integration processes seem to be better explained by models that partially rely on automatic processes such as decision field theory or parallel constraint satisfaction models.

Conditioned behavior as observed during classical conditioning in a group of identically treated animals provides insights into the physiological process of learning and memory formation. However, several studies in vertebrates found a remarkable difference between the group-average behavioral performance and the behavioral characteristics of individual animals. Here, we analyzed a large number of data (1640 animals) on olfactory conditioning in the honeybee (Apis mellifera). The data acquired during absolute and differential classical conditioning differed with respect to the number of conditioning trials, the conditioned odors, the intertrial intervals, and the time of retention tests. We further investigated data in which animals were tested for spontaneous recovery from extinction. In all data sets we found that the gradually increasing group-average learning curve did not adequately represent the behavior of individual animals. Individual behavior was characterized by a rapid and stable acquisition of the conditioned response (CR), as well as by a rapid and stable cessation of the CR following unrewarded stimuli. In addition, we present and evaluate different model hypotheses on how honeybees form associations during classical conditioning by implementing a gradual learning process on the one hand and an all-or-none learning process on the other hand. In summary, our findings advise that individual behavior should be recognized as a meaningful predictor for the internal state of a honeybee--irrespective of the group-average behavioral performance. 相似文献

Individuals decide to use healthcare when the expected benefits outweigh the perceived costs. One of these cost factors in this decision can be stigma. So far, it has not been researched how former soldiers of the German Armed Forces with a service-induced mental illness perceive stigma and how it influences their healthcare use. As stigma is shaped by the socio-cultural context, the setting of the potential healthcare use must be considered. Narrative interviews were conducted with 33 former soldiers with mental health problems. The data were analyzed using a thematic analysis approach, in which codes were formed and emerging themes were systemized. The relationship between stigma and healthcare use was analyzed. Occupational discrimination and social exclusion were experienced in both in the military and civilian context, but stigma functioned differently in each context. In the military context, former soldiers’ self-stigma of mentally ill individuals being weak was in stark contrast to their internalized military standards. This contrast let them avoid disclosure and subsequent healthcare use. In civilian context, the participants perceived 2 different stigma costs: mental illness stigma and former soldier stigma (i.e., stigmatization because of their military past). Both were perceived as barriers to healthcare use. A model, illustrating these different stigma costs in the different contexts, was developed. Further research on the link between stigma and healthcare use of this group is urgently needed. 相似文献

The “Model for Reaching Ethical Judgments in the context of Modern Technologies — the Case of Genetic Technology”, which is presented here, has arisen from the project “Ethical Criteria bearing upon Decisions taken in the field of Biotechnology”. This project has been pursued since 1991 in the Zentrum für interdisziplinäre Technikforschung (ZIT) of the Technical University of Darmstadt, with the purpose of examining decision-making in selected activities involving the production of transgenic plants that have a useful application. The model is the basis of an outline for interviews to investigate how far decisions concerning the development of such plants with genetic techniques take ethical criteria into account. It was necessary to design this new model because other models for reaching judgments of this kind were not conceptually suited for concrete application. This model represents a problem related approach and combines methodological with substantive typology. In this it differs from comparable models for reaching ethical judgments. 相似文献

Previous research has conceptualized dispositional envy as a general construct that does not vary across comparison domains. In five studies (N = 1393), we examine dispositional envy as a domain‐specific construct. In Study 1, we present the development of a domain‐specific measure of dispositional envy. Across samples from different populations and two countries (Studies 2 and 3), the measure is shown to have good reliability, construct validity and stability over three months, highlighting the trait‐like character of the construct. State levels of envy were also examined in the academic domain (Study 4) and in dyadic interactions between unacquainted participants (Study 5). Results show a Person × Situation Interaction effect (i.e. Dispositional Envy × Situation) on experiences of envy. By placing domain‐specific dispositional envy into a network of similar and dissimilar constructs, the current findings serve as a foundation for drawing conclusions about the nature of dispositional envy.

Point-light displays of human gait provide information sufficient to recognize the gender of a walker and are taken as evidence of the exquisite tuning of the visual system to biological motion. The authors revisit this topic with the goals of quantifying human efficiency at gender recognition. To achieve this, the authors first derive an ideal observer for gender recognition on the basis of center of moment (J. E. Cutting, D. R. Proffitt, & L. T. Kozlowski, 1978) and, with the use of anthropometric data from various populations, show optimal recognition of approximately 79% correct. Next, they perform a meta-analysis of 21 experiments examining gender recognition, obtaining accuracies of 66% correct for a side view and 71% for other views. Finally, results of the meta-analysis and the ideal observer are combined to obtain estimates of human efficiency at gender recognition of 26% for the side view and 47% for other views. 相似文献

Kant and Confucius maintain that the art of becoming human is synonymous with the unending process of becoming moral. According
to Kant, I must imagine a world in which the universality of my maxims were possible, while realizing that if such a world existed, then morality
would disappear. Morality is an impossible possibility because it always meets resistance in our encounter with nature. According
to Confucius, human beings become moral by integrating themselves into the already meaningful natural order that is tian 天. Like Kant, he upholds the dignity of human beings. For Kant this dignity rests on the autonomy of each human being’s reason,
while for Confucius it is dependent upon our interconnection with each other, demanding ongoing self-extension. Despite these
differences, the two thinkers would concur that our efforts at humanization are unceasing and that we may never fully live
up to our human potential. 相似文献

This work investigates the nature of two distinct response patterns in a probabilistic truth table evaluation task, in which people estimate the probability of a conditional on the basis of frequencies of the truth table cases. The conditional-probability pattern reflects an interpretation of conditionals as expressing a conditional probability. The conjunctive pattern suggests that some people treat conditionals as conjunctions, in line with a prediction of the mental-model theory. Experiments 1 and 2 rule out two alternative explanations of the conjunctive pattern. It does not arise from people believing that at least one case matching the conjunction of antecedent and consequent must exist for a conditional to be true, and it does not arise from people adding the converse to the given conditional. Experiment 3 establishes that people's response patterns in the probabilistic truth table task are very consistent across different conditionals, and that the two response patterns generalize to conditionals with negated antecedents and consequents. Individual differences in rating the probability of a conditional were loosely correlated with corresponding response patterns in a classical truth table evaluation task, but there was little association with people's evaluation of deductive inferences from conditionals as premises. A theoretical framework is proposed that integrates elements from the conditional-probability view with the theory of mental models. 相似文献
