An action crisis is defined as an intra-psychic conflict between further goal pursuit and disengagement from the goal and frequently signifies the beginning of disengagement processes. By analyzing dispositional predictors of the development of goal-related action crises over time, we applied a process-based approach to goal disengagement. In two longitudinal studies, we evaluated the effect of action (vs. state) orientation on the development of action crises. Using change-regression models, the hypothesis could be confirmed that action orientation enables individuals to overcome action crises in personal goals. Furthermore, in two cross-sectional studies, previously reported effects of action orientation on health and well-being could be replicated and shown to be partially mediated by a decreased overall prevalence of action crises.  相似文献

We create a sense of time, our understanding of time and subjective time in our minds by experiencing memories, images and chains of events in life as consecutive sequences. We also create timelessness within ourselves. If a person powerfully experiences the present moment, linking this feeling of integration to the self the feeling of timelessness and illusion of eternity is reinforced, making both the past and the future seem less significant than the present moment. A negative experience of timelessness is linked both to the fear that life will end as well as to the fear of disintegration, shattering, the loss of the self and corporeality. By contrast, a positive experience of timelessness enriches and integrates the personality, linking experiences together in a highly personal and authentic way with a great feeling of freedom which is not tied to a specific point in time. The author argues that a creative experience is always based on an inner, timeless dialogue, even when it is manifested in the transference of psychoanalysis. Through his attitude, an analyst can influence both the analysand's creativity and his experience of timelessness by reinforcing the role of the analysand's true self in his experiences of the self as a whole. Further, a mystical experience could be an act of sublimation taking place during psychoanalytic transference, while communing with nature, or while being creative. Deeply experiencing something truly representing a personal truth as a timeless experience, in a mystical experience or a dream, is probably linked to the ability to fully experience a moment in and of itself, without external stimuli, and with the ability to objectify the self. During such moments, a person can look into himself truly and openly, without any other immediate aspirations.  相似文献

In his Parts of Animals, Aristotle distinguishes three modes of the necessary.However, it is not clear just what these three modes are.Nor is it clear how this passage fits with other texts where Aristotle distinguishes modalities in different ways.Here I present and explain Aristotle’s three modes of necessity, and claim that they are the only three recognized by Aristotle.I then explain how this passage agrees with other passages where Aristotle mentions formal and structural features of the modalities.I end by showing how having three modes of necessity does not make ‘necessary’ ambiguous.Rather, I claim, Aristotle has a single, central notion of necessity and hence a unified theory of modality  相似文献

Most words are associated with multiple senses. A DVD can be round (when describing a disc), and a DVD can be an hour long (when describing a movie), and in each case DVD means something different. The possible senses of a word are often predictable, and also constrained, as words cannot take just any meaning: for example, although a movie can be an hour long, it cannot sensibly be described as round (unlike a DVD). Learning the scope and limits of word meaning is vital for the comprehension of natural language, but poses a potentially difficult learnability problem for children. By testing what senses children are willing to assign to a variety of words, we demonstrate that, in comprehension, the problem is solved using a productive learning strategy. Children are perfectly capable of assigning different senses to a word; indeed they are essentially adult-like at assigning licensed meanings. But difficulties arise in determining which senses are assignable: children systematically overestimate the possible senses of a word, allowing meanings that adults rule unlicensed (e.g., taking round movie to refer to a disc). By contrast, this strategy does not extend to production, in which children use licensed, but not unlicensed, senses. Children’s productive comprehension strategy suggests an early emerging facility for using context in sense resolution (a difficult task for natural language processing algorithms), but leaves an intriguing question as to the mechanisms children use to learn a restricted, adult-like set of senses.  相似文献

The aim of the present study was to examine if perceived normative pressure (i.e., perception of the normative expectations of family and friends regarding one's intergroup attitudes) had a direct impact on majority youth's (N = 93) explicit attitudes and moderated the relationship between their implicit (measured with the ST-IAT) and explicit attitudes towards Russian immigrants in Finland. The results indicated that normative pressure is positively associated with the explicit attitudes of adolescents, and that the implicit attitudes of the adolescents towards immigrants surface on the explicit level only when they do not perceive a normative pressure to hold positive intergroup attitudes. More specifically, when there is no normative pressure, the explicit attitudes of youth are, at best, neutral, and reflect their implicit attitudes. In contrast, when normative pressure is perceived to be high, the level of explicit attitudes is generally more positive, and the expression of explicit attitudes is not determined by implicit attitudes. The effects of age, sex, quality of past intergroup contact experiences, and intergroup anxiety were controlled for in the analysis. The findings highlight the importance of taking normative pressure into consideration when studying socially sensitive ethnic attitudes among adolescents.  相似文献

In a survey questionnaire, 81 Swedish managers working in the private and public sectors were presented with scenarios in which a manager chose among inefficient (i.e., economically worse) alternatives, implying equal rewards to subordinates; and efficient (i.e., economically better) alternatives, implying unequal rewards. The managers also rated 26 different emotion words, describing their responses to the inequality of rewards in the scenarios. The results showed stronger outward‐directed and inward‐directed negative emotions, and weaker inward‐directed positive emotions when the inequality of rewards increased. Furthermore, negative emotions were found to mediate the choices among efficient and inefficient alternatives.  相似文献

The study was planned to evaluate the effect of loss of hearing and vision on balance and gait in 60 children, 20 of whom had hearing loss (M age = 9.3 yr., SD = 0.9), 20 who were visually impaired (M age = 12.2 yr., SD = 2.5), and 20 controls with no disability (M age = 9.4 yr., SD = 0.6). Standing Balance subtests of the Southern California Sensory Integration Tests were used. Gait analysis was conducted on a powdered surface. When the gait analysis results of the three groups of children were compared, statistically significant differences were noted. Scores for the hearing impaired group were more like those of the control group than those of the visually impaired group. Results show that children with visual impairment had more problems with balance and gait than controls.  相似文献

This article presents current philosophical reflections on religious diversity and concomitant attitudes towards the interreligious situation. The motive behind this presentation is to show that in order to deal more efficiently with the phenomenon of religious plurality, there is a need for a development of the philosophy of religion, where new perspectives are opened up and explored. The very concept of religion as a belief system is put into question, since it has caused philosophical reflections on religious diversity to be confined to certain metaphysical and epistemological concerns. Instead of focusing on the noun ‘religion’, the article suggests a way to understand the adjective ‘religious’ and view religious plurality as a plurality of ways of being religious. This opens up a certain context of interreligious relations and interreligious dialogue, where this very dialogue itself can contribute to the development of philosophical tools, concepts and categories for dealing with the fact of plurality. I call this context constructive dialogical pluralism.  相似文献

The transition into middle school may be a risky period in early adolescence. In particular, friendships, peer status, and parental monitoring during this developmental period can influence the development of problem behavior. This study examined interrelationships among peer and parenting factors that predict changes in problem behavior over the middle school years. A longitudinal sample (580 boys, 698 girls) was assessed in Grades 6 and 8. Peer acceptance, peer rejection, and their interaction predicted increases in problem behavior. Having high-achieving friends predicted less problem behavior. Parental monitoring predicted less problem behavior in general, but also acted as a buffer for students who were most vulnerable to developing problem behavior on the basis of being well liked by some peers, and also disliked by several others. These findings highlight the importance of studying the family–peer mesosystem when considering risk and resilience in early adolescence, and when considering implications for intervention.  相似文献
