The relationship between severe early institutional deprivation and scholastic attainment at age 11 in 127 children (68 girls
and 59 boys) adopted from institutions in Romania was compared to the attainment of 49 children (17 girls and 32 boys) adopted
within the UK from a non-institutional background. Overall, children adopted from Romania had significantly lower attainment
scores than those adopted within the UK; the children within the Romanian sample who had spent 6 months or more in an institution
had significantly lower attainment scores than those who had spent less than 6 months in an institution, but there was no
additional risk of low attainment associated with longer institutional care after 6 months. The lower scholastic attainment
in the children adopted from Romanian institutions, as compared with domestic adoptees, was mediated by IQ, and to a lesser
degree, inattention/overactivity. When these factors were taken into account, only small between-group differences in attainment
remained. 相似文献

The effects of exposure to muscular male models among men: exploring the moderating role of gym use and exercise motivation 总被引:1,自引:1,他引:0
This study examines the effects of exposure to the muscular male body ideal on body-focused negative affect among male gym users and non-exercisers. As hypothesized, the impact of media exposure depended on men's exercise status. Non-exercisers (n = 58) reported greater body-focused negative affect after exposure to images of muscular male models than after neutral images (no model controls), whereas gym users (n = 58) showed a tendency for less body-focused negative affect after the model images than after the control images. Furthermore, the extent to which gym users were motivated to increase strength and muscularity moderated these exposure effects; men who reported stronger strength and muscularity exercise motivation reported a greater degree of self-enhancement after exposure to the muscular ideal. The findings are interpreted with respect to likely differences in motives for social comparisons. 相似文献

Previous studies have found that in American culture high-arousal positive states (HAP) such as excitement are valued more and low-arousal positive states (LAP) such as calm are valued less than they are in Chinese culture. What specific factors account for these differences? The authors predicted that when people and cultures aimed to influence others (i.e., assert personal needs and change others' behaviors to meet those needs), they would value HAP more and LAP less than when they aimed to adjust to others (i.e., suppress personal needs and change their own behaviors to meet others' needs). They test these predictions in 1 survey and 3 experimental studies. The findings suggest that within and across American and Chinese contexts, differences in ideal affect are due to specific interpersonal goals. 相似文献

In this article I give an overview of some recent work in philosophy of science dedicated to analysing the scientific process in terms of (conceptual) mathematical models of theories and the various semantic relations between such models, scientific theories, and aspects of reality. In current philosophy of science, the most interesting questions centre around the ways in which writers distinguish between theories and the mathematical structures that interpret them and in which they are true, i.e. between scientific theories as linguistic systems and their non-linguistic models. In philosophy of science literature there are two main approaches to the structure of scientific theories, the statement or syntactic approach—advocated by Carnap, Hempel and Nagel—and the non-statement or semantic approach—advocated, among others, by Suppes, the structuralists, Beth, Van Fraassen, Giere, Wójcicki. In conclusion, I briefly review some of the usual realist inspired questions about the possibility and character of relations between scientific theories and reality as implied by the various approaches I discuss in the course of the article. The models of a scientific theory should indeed be adequate to the phenomena, but if the theory is ‘adequate’ to (true in) its conceptual (mathematical) models as well, we have a model-theoretic realism that addresses the possible meaning and reference of ‘theoretical entities’ without relapsing into the metaphysics typical of the usual scientific realist approaches. 相似文献

The purpose of the study was to examine the relationship between perceptions of the motivational team climate and task and social cohesion among male college athletes. Basketball and soccer players (n = 179) completed two response measures, the Perceived Motivational Climate in Sport Questionnaire‐II (Newton, Duda, & Yin) and the Group Environment Questionnaire (GEQ; Carron, Widmeyer, & Brawley) before practice in a team setting near the end of the competitive season. Hierarchical linear modeling analysis revealed that individual perceptions of a task‐involving climate positively predicted, and perceptions of an ego‐involving climate negatively predicted, individual‐attraction‐to‐group task cohesion. Further analysis indicated that perceptions of a task‐involving climate also significantly predicted individual‐attraction‐to‐group social cohesion and group‐integration task cohesion. Perceptions of an ego‐involving climate failed to demonstrate any other predictive value in relation to team cohesion. Discussion underscores the beneficial nature of a task‐involving motivational team climate in regard to the formation and development of task and social cohesion among competitive male college athletes. 相似文献

Theories of self-regulation emphasize the special role that the symbolic self may play in approach and avoidance movements, but experimental evidence is lacking. In two experiments (total N = 157), participants moved either a self-relevant (e.g., “me”) or non-self (e.g., “not me”) agent to one of two locations, one occupied by a positive word and the other occupied by a negative word. In both experiments, the movement agent interacted with the destination valence such that it was only the symbolic self that moved more quickly to positive rather than negative locations. These results established a role for the symbolic self in approach/avoidance that had been questioned, thereby supporting both classic and contemporary self-related theories of approach and avoidance. 相似文献

The recent revolutions known as the Arab Spring have been characterized as the products of social media. However, there is an alternative view that revolution takes place on the street or the battlefield and that the role of social media has been overstated. We argue that some new technologies can serve to facilitate rapid social change when they provide ways to overcome restrictions on the freedoms of expression and association. In doing so, communication technologies enable the formation of new social identities that can challenge existing social orders by promoting the growth of a social movement that is positioned as loyal to the nation and its people but opposed to the government. Our analyses focus on the role of social media in spreading video images of dissent and the links between this video material, satellite television, and mobile telephones in Tunisia and Egypt. 相似文献

The benefits of testing on learning are well described, and attention has recently turned to what happens when errors are elicited during learning: Is testing nonetheless beneficial, or can errors hinder learning? Whilst recent findings have indicated that tests boost learning even if errors are made on every trial, other reports, emphasizing the benefits of errorless learning, have indicated that errors lead to poorer later memory performance. The possibility that this discrepancy is a function of the materials that must be learned—in particular, the relationship between the cues and targets—was addressed here. Cued recall after either a study-only errorless condition or an errorful learning condition was contrasted across cue–target associations, for which the extent to which the target was constrained by the cue was either high or low. Experiment 1 showed that whereas errorful learning led to greater recall for low-constraint stimuli, it led to a significant decrease in recall for high-constraint stimuli. This interaction is thought to reflect the extent to which retrieval is constrained by the cue–target association, as well as by the presence of preexisting semantic associations. The advantage of errorful retrieval for low-constraint stimuli was replicated in Experiment 2, and the interaction with stimulus type was replicated in Experiment 3, even when guesses were randomly designated as being either correct or incorrect. This pattern provides support for inferences derived from reports in which participants made errors on all learning trials, whilst highlighting the impact of material characteristics on the benefits and disadvantages that accrue from errorful learning in episodic memory. 相似文献
