Two experiments were conducted to verify the influence of various mental simulations on the effectiveness and persistence of weight loss processes. In study one, 40 female students (aged 19–27, M = 23) who were eager to lose weight were randomly assigned to one of four groups: positive outcome simulation, process simulations, mixed simulations (process followed by negative outcome), and control (no simulations). Students from the mixed and process simulation groups lost significantly more weight after five weeks than participants from the outcome simulation and control groups. A total of 106 females (aged 19–45, M = 29) participated in study two, in which five types of mental simulations were tested. Besides the images used in study one, process followed by positive outcome simulations and negative outcome simulations were implemented. Results showed that process followed by positive outcome simulations lead to the highest persistence in the weight loss process, while process followed by negative outcome simulations induced the greatest reduction in weight. Both studies revealed self-regulatory benefits from mental simulations in difficult and long-term personal goal attainment. 相似文献

The aim of this paper is to describe from a semantic perspective the problem of conservativity of classical first-order theories over their intuitionistic counterparts. In particular, we describe a class of formulae for which such conservativity results can be proven in case of any intuitionistic theory T which is complete with respect to a class of T-normal Kripke models. We also prove conservativity results for intuitionistic theories which are closed under the Friedman translation and complete with respect to a class of conversely well-founded Kripke models. The results can be applied to a wide class of intuitionistic theories and can be viewed as generalization of the results obtained by syntactic methods. 相似文献

We investigate a simple game paradigm for intuitionistic logic, inspired by Wajsberg’s implicit inhabitation algorithm and Beth tableaux. The principal idea is that one player, ?ros, is trying to construct a proof in normal form (positions in the game represent his progress in proof construction) while his opponent, ?phrodite, attempts to build a counter-model (positions or plays can be seen as states in a Kripke model). The determinacy of the game (a proof-construction and a model-construction game in one) implies therefore both completeness and semantic cut-elimination. 相似文献

The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants’ body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain. 相似文献

Some people might believe that individuals who are more satisfied with their body are also happier. However, people tend to overrate the influence of some factors (e.g. money or health) on their happiness; a phenomenon termed the focusing illusion. Our aim was to examine the focusing illusion in relation to body satisfaction. We experimentally manipulated body satisfaction and life satisfaction focus by varying the order of relevant measurement scales. Volunteers (N = 97) completed two questionnaires placed in separate envelopes to control the order of scales administration. Participants either completed the Body Satisfaction Scale followed by the Satisfaction with Life Scale or vice versa. In line with the focusing illusion the association between body satisfaction and life satisfaction was significantly stronger when participants were asked about their body satisfaction first. Body satisfaction as a focusing illusion may need to be considered by scientist as well as lay people who try to look better and be happier. 相似文献

Previous research indicates that political conservatism is associated with epistemic needs for structure and certainty (Jost et al., 2003) and that nouns elicit clearer and more definite perceptions of reality than other parts of speech (Carnaghi et al., 2008). We therefore hypothesized that conservatives would exhibit preferences for nouns (vs. verbs and adjectives), insofar as nouns are better suited to satisfy epistemic needs. In Study 1, we observed that social conservatism was associated with noun preferences in Polish and that personal need for structure accounted for the association between ideology and grammatical preferences. In Study 2, conducted in Arabic, social conservatism was associated with a preference for the use of nominal sentences (composed of nouns only) over verbal sentences (which included verbs and adjectives). In Study 3, we found that more conservative U.S. presidents used greater proportions of nouns in major speeches, and this effect was related to integrative complexity. We discuss the possibility that conservative ideology is linked to grammatical preferences that foster feelings of stability and predictability. 相似文献

The aim of this study was to assess the memory of pain induced by running a marathon and the factors that influence it. Sixty-two marathon runners participated in the study, which comprised two phases. Immediately after a participant had reached the finishing line of the marathon, they were asked to rate the intensity and the unpleasantness of their pain and the emotions they felt at that time. Either three or six months later they were asked again to rate the intensity and the unpleasantness of the same pain experience. Regardless of the length of recall delay, participants underestimated both recalled pain intensity and unpleasantness. The pain and negative affect reported at the time of the pain experience accounted for 24% of the total variance in predicting recalled pain intensity and 22% of the total variance in predicting recalled pain unpleasantness. Positive affect at the time of pain experience was not a significant predictor of both the recalled pain intensity and pain unpleasantness. It is concluded that pain induced by physical exercise is not remembered accurately and the pain and negative affect experienced influence recall. Further research is needed on the influence of positive affect on the memory of pain. 相似文献

The main goal of the paper is to sketch an ontological model of visual content at the low- and medium-level of visual processing, relying on psychological conceptions of vision. It is argued that influential cognitive models contain assumptions concerning “objects of content,” that is, objects whose presence is a necessary condition of the adequacy of visual representations. Subsequently, the structure of considered objects of content is presented, and its development through the perceptual process is described. In addition, during the course of the article I present some connections between analytic metaphysics and the ontology of visual content. 相似文献

The main aims of this study were to assess memory of pain and pain-related affect in headache sufferers and to compare the pain memories of individuals who suffer from migraines and those who experience non-migraine headaches. A total of 313 women participated in the study, 86 of whom had a diagnosis of migraine headache. The women rated their state anxiety about having a headache, the intensity and unpleasantness of headache pain, and their emotions while actually experiencing a headache. Either three or six months later, the participants were asked to recall their state anxiety, the intensity and unpleasantness of pain, and the emotions they had felt. Regardless of the length of recall delay or migraine diagnosis, participants accurately remembered both pain intensity and unpleasantness. Together, recalled anxiety, experienced pain and recalled positive affect were the most important predictors of memories for headache, accounting for 41% and 37% of the total variance in recalled pain intensity and unpleasantness, respectively. However, participants overestimated recalled positive and negative affect. The effect of recalled affect on memory of headache, together with the overestimation of recalled affect, suggests that although memory of headache is accurate, it is influenced by distorted memories of affect. 相似文献
