Scientific discoveries about the dangers of smoking and antismoking actions carried out in Western countries over recent decades have progressively helped create an antismoking social norm. Nevertheless, many smokers still refuse to quit. We conducted two studies to investigate smokers' resistance to this norm as a function of their personal self‐esteem (PSE) and group‐based self‐esteem (GBSE). An initial correlational study assessed smokers' perception of the antismoking social norm, their PSE, and their antismoking attitudes. Smokers with low PSE had lower antismoking attitudes than those with high PSE when the antismoking norm was strong. The second study assessed GBSE (i.e., smokers' satisfaction as smokers) and manipulated both the strength of the antismoking norm and PSE (i.e., focus on personal weaknesses or strengths). Smokers with low PSE displayed the lowest antismoking attitudes when the antismoking norm was strong and their GBSE was high. These results show that the antismoking norm can produce paradoxical effects and suggest that the way individuals cope with stigmatization is affected by the interplay between PSE and GBSE.

Abstract Endeavoring to conquer space—a domain once reserved to gods and spirits—is not always a denial of the existence of divinities and the human practices devoted to them. On the contrary, many examples of religious attitudes can be seen in the space venture of the past 50 years or so, such as lighting candles before launching a rocket or blessing a team of cosmonauts. To say that such behavior is an expression of the sacred dimension means recognizing that the space venture goes beyond the usual borders of human existence but, at the same time, does not reveal everything about mankind. There must always be a place for terrae incognitae—for unknown and uncharted lands. 相似文献

Posttraumatic stress disorder (PTSD) affects the functional recruitment and connectivity between neural regions during autobiographical memory (AM) retrieval that overlap with default and control networks. Whether such univariate changes relate to potential differences in the contributions of the large-scale neural networks supporting cognition in PTSD is unknown. In the present functional MRI study, we employed independent-component analysis to examine the influence of the engagement of neural networks during the recall of personal memories in a PTSD group (15 participants) as compared to non-trauma-exposed healthy controls (14 participants). We found that the PTSD group recruited similar neural networks when compared to the controls during AM recall, including default-network subsystems and control networks, but group differences emerged in the spatial and temporal characteristics of these networks. First, we found spatial differences in the contributions of the anterior and posterior midline across the networks, and of the amygdala in particular, for the medial temporal subsystem of the default network. Second, we found temporal differences within the medial prefrontal subsystem of the default network, with less temporal coupling of this network during AM retrieval in PTSD relative to controls. These findings suggest that the spatial and temporal characteristics of the default and control networks potentially differ in a PTSD group versus healthy controls and contribute to altered recall of personal memory. 相似文献

Prism adaptation induces rapid recalibration of visuomotor coordination. The neural mechanisms of prism adaptation have come under scrutiny since the observations that the technique can alleviate hemispatial neglect following stroke, and can alter spatial cognition in healthy controls. Relative to non-imaging behavioral studies, fMRI investigations of prism adaptation face several challenges arising from the confined physical environment of the scanner and the supine position of the participants. Any researcher who wishes to administer prism adaptation in an fMRI environment must adjust their procedures enough to enable the experiment to be performed, but not so much that the behavioral task departs too much from true prism adaptation. Furthermore, the specific temporal dynamics of behavioral components of prism adaptation present additional challenges for measuring their neural correlates. We developed a system for measuring the key features of prism adaptation behavior within an fMRI environment. To validate our configuration, we present behavioral (pointing) and head movement data from 11 right-hemisphere lesioned patients and 17 older controls who underwent sham and real prism adaptation in an MRI scanner. Most participants could adapt to prismatic displacement with minimal head movements, and the procedure was well tolerated. We propose recommendations for fMRI studies of prism adaptation based on the design-specific constraints and our results. 相似文献

The current study explored the relationships between declarative pointing and theory of mind abilities in 30 children between 3 and 4 years of age. Measures used to examine theory of mind (ToM) included a parental questionnaire and the Scaling of Theory of Mind Tasks. Results showed a dissociation between expressive and informative pointing, which have been regarded as two subcategories of the declarative function. ToM abilities were significantly related to the production of informative pointing, but not to the production of expressive pointing. This distinction might be explained by special features associated with informative pointing, such as early signs of cooperation abilities. Our results might have key implications for psychologists, as they may help improve evaluation and intervention programs for the development of social skills in preschoolers. 相似文献

This study investigated the development of hand preference for bimanual manipulative activities and pointing gestures in toddlers observed longitudinally over a 5-month period, in relation to language acquisition. The lexical spurt was found to be accompanied by an increase in the right-sided bias for pointing but not for manipulation. Moreover, results revealed a significant correlation between hand preference for imperative pointing gestures and manipulative activities in children who did not experience the lexical spurt during the observational period. By contrast, measures of handedness for declarative pointing were never correlated with those of handedness for manipulation. This study illustrates the complex relationship between handedness and language development and emphasizes the need to take the different functions of pointing gestures into account. 相似文献

This study aimed to investigate (a) whether it is possible to increase emotional competence (EC) in adulthood; (b) whether this improvement results in better mental, physical, and social adjustment; (c) whether this improvement can be maintained 1 year later; and (d) whether these benefits are accompanied by a reduction in stress-hormone secretion (i.e., cortisol). One hundred and thirty-two participants were randomly assigned to an EC-enhancing intervention (in group format) or to a control group. Participants in the intervention group underwent a specifically designed 15-hr intervention targeting the 5 core emotional competencies, complemented with a 4-week e-mail follow-up. Results reveal that the level of emotional competencies increased significantly in the intervention group in contrast with the control group. This increase resulted in lower cortisol secretion, enhanced subjective and physical well-being, as well as improved quality of social and marital relationships in the intervention group. No significant change occurred in the control group. Peer reports on EC and quality of relationships confirmed these results. These data suggest that emotional competencies can be improved, with effective benefits on personal and interpersonal functioning lasting for at least 1 year. The theoretical implications of these results as well as their practical implications for the construction and the development of effective emotional competencies interventions are discussed. 相似文献

Accidental falls in older individuals are a major health and research topic. Increased reaction time and impaired postural balance have been determined as reliable predictors for those at risk of falling and are important functions of the central nervous system (CNS). An essential risk factor for falls is medication exposure. Amongst the medications related to accidental falls are the non-steroidal anti-inflammatory drugs (NSAIDs). About 1-10% of all users experience CNS side effects. These side effects, such as dizziness, headaches, drowsiness, mood alteration, and confusion, seem to be more common during treatment with indomethacin. Hence, it is possible that maintenance of (static) postural balance and swift reactions to stimuli are affected by exposure to NSAIDs, indomethacin in particular, consequently putting older individuals at a greater risk for accidental falls. The present study investigated the effect of a high indomethacin dose in healthy middle-aged individuals on two important predictors of falls: postural balance and reaction time. Twenty-two healthy middle-aged individuals (59.5 ± 4.7 years) participated in this double-blind, placebo-controlled, randomized crossover trial. Three measurements were conducted with a week interval each. A measurement consisted of postural balance as a single task and while concurrently performing a secondary cognitive task and reaction time tasks. For the first measurement indomethacin 75 mg (slow-release) or a visually identical placebo was randomly assigned. In total, five capsules were taken orally in the 2.5 days preceding assessment. The second measurement was without intervention, for the final one the first placebo group got indomethacin and vice versa. Repeated measures GLM revealed no significant differences between indomethacin, placebo, and baseline in any of the balance tasks. No differences in postural balance were found between the single and dual task conditions, or on the performance of the dual task itself. Similarly, no differences were found on the manual reaction time tasks. The present study showed that a high indomethacin dose does not negatively affect postural balance and manual reaction time in this healthy middle-aged population. Although the relatively small and young sample limits the direct ability to generalize the results to a population at risk of falling, the results indicate that indomethacin alone is not likely to increase fall risk, as far as this risk is related to abovementioned important functions of the CNS, and not affected by comorbidities. 相似文献

Immigration, cultural diversity and integration are among the most central challenges for modern societies. Integration is often impeded by negative emotions and prejudices held by the majority members towards immigrants in a common society. Based on the ingroup projection model (Mummendey & Wenzel, 1999), we examined the impact of perceived relative ingroup prototypicality on intergroup emotions and prejudice. Additionally, we examined whether this impact is causal and explored the issue of causality in more detail contrasting a linear causal model with bi‐directional or reciprocal causality. Hypotheses were tested in a study with a two‐wave panel of majority members (N=1085) in Germany. We examined the proposed relations between relative ingroup prototypicality, intergroup emotions and prejudice and determined the causal direction of these relationships. Results support the predictive power of relative ingroup prototypicality on intergroup emotions and prejudice. Moreover, most causal relations between our measures are reciprocally causal. We discuss the implications of these findings for the general conception of prejudice and intergroup emotions. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
