There is a growing concern among health authorities that an increasing number of people in the Western world become overweight and even obese. It is well known that obesity is related to several diseases (e.g., diabetes, stroke, and high blood pressure) and that such diseases related to obesity lead to early death. It has also been discussed whether overweight and obesity in themselves or in relation to such diseases lead to cognitive decline. On the basis of data from a large, population‐based, prospective study we examined three cognitive domains: episodic memory, semantic memory, and spatial ability. Two body measures were used to define normal weight and overweight, body‐mass index and waist/hip ratio. Although these two body measures reveal quite different prevalence data of overweight, the associations between overweight and cognition are similar. For episodic memory, overweight interacts with age, but when controlling for hypertension, stroke and diabetes, this interaction disappears. For semantic memory, normal weight participants outperform overweight participants even after controlling for these diseases. For spatial ability, the well‐established advantage for men holds for young‐old and old‐old normal‐weight participants. For overweight participants, this advantage holds for middle‐age participants only. We conclude that there is a weight‐cognition relationship even after controlling for obesity‐related diseases. The results are discussed in terms of possible biological mechanisms.  相似文献

Snakes and faces are unique stimuli because they are deeply grounded in evolutionarily shaped behavior systems. Snakes are the prototypical stimulus in a predatory defense system promoting escape from predators, which prepares primates for efficient processing, attentional priority, and rapid fear acquisition to snakes and other stimuli related to predation. The social submissiveness system plays a similar role on the social arena by promoting yielding to dominant individuals without jeopardizing the protection of the group. Supporting these theoretical propositions, empirical data from a research program spanning four decades demonstrate enhanced fear conditioning to snakes and threatening faces compared to neutral stimuli, as well as fast nonconscious processing of, and prioritized attention to, snakes and threatening faces. Human brain‐imaging data show that these effects are mediated by an extensive fear‐network centering on the amygdala.  相似文献

This article presents a group position model of prejudice and a set of individual-level theoretical approaches to explain prejudice toward immigrants, who are a relatively new minority group in Western Europe. It specifically tests the effects of the perceived threat posed by the new minorities to the dominant group position of the citizens in the European nation-states. Threat is measured both as individuals’ perceptions of threat over economic and sociocultural resources and as contextual factors. Results show that individuals’ perception of threat to their ingroup’s position has the most powerful effect on prejudice, whereas context does not seem to matter. The findings imply that sources of perceived threat should be addressed to help reduce prejudice.  相似文献

This study examined the factorial structure of data generated in the Videotaped Structured Interview for assessment of Type A behavior. Based on the literature, it was argued that there are at least three distinct concepts of Type A behavior, focused on competitiveness and pressured drive, speech characteristics, and hostility, respectively. These three concepts were clearly represented among the factors from factor analyses based on data from 282 subjects. Three factors represented speech and psychomotor characteristics, where the first reflected interactions between subject and interviewer (e.g., response latency, interruptions), the second tempo of speech (accelerating, dysrhythmic and rapid speech), and the third oral gestures (e.g., expiratory sighs). Hostility was reflected in two factors, one defined by emotional intensity (e.g., anger when recalling paat event) and the other hostility expressed towards the interviewer. Pressured drive dominated a content factor reflecting self-awareness of Type A behavior. Finally, there was one factor related to psychomotor tension. Through further factor and item analyses, it was possible to combine these factors into three homogeneous and moderately intercorrelated subscales of Type A behavior reflecting Hostility, Speech Characteristics, and Self-Awareness of Type A behavior. These scales showed good interrater agreement and stability over two years. The Self-Awareness Scale was highly correlated with self-report measures of Type A behavior. The Hostility Scale, on the other hand, was moderately related to measures of Type A behavior, anger and hostility, but was unrelated to anxiety. The Speech Characteristic Scale, finally, was virtually unrelated to psychometric measures.  相似文献

Therapeutic factors in an inpatient group from Turkey are presented. A total of 40 patients were seen over a period of 2 years and each patient was given Yalom's (1983) 60-item therapeutic factor list on discharge. The first four most valued therapeutic factor groups were Catharsis, Existential Factors, Cohesiveness and Hope. There were significant differences in the highly valued factors in different diagnostic groups. Patients with diagnoses of anxiety/somatization and borderline/identity problem preferred factors resembling those in many out-patient studies. The results are discussed in the light of relevant literature.  相似文献

This study of naturally occurring behaviour employed a "beeper technique" to investigate the actions carried out by 152 subjects in eight different groups, viz. adult students, employed students who were also parents, unemployed, art students, doctoral students, alcoholics, retired people and a control group. Actions were sampled for seven subsequent days, five times per day between 8 a.m. and 10 p.m. at randomly selected occasions. Each action was rated on a number of variables, shortly after it was sampled (median delay approximately 10 min). Some of the findings were: Time allocation corresponded well with national estimates. Being under situational control was highly aversive. Instrumental and consummatory orientations correlated positively. The background variables were, on the whole, only rather weakly related to action ratings, but it was found that women and retired persons tended to report a higher level of well-being.  相似文献

The importance of individual response patterns in claustrophobic patients was examined in the present study. Thirty-four psychiatric outpatients with a phobia of enclosed spaces were assessed in a small test chamber. During the test their overt behavior was video-taped, heart-rate was measured continuously, and self-ratings of experienced anxiety were made at certain intervals. On the basis of their reactions in the test situation, the patients were divided into two groups showing different response patterns—behavioral and physiological reactors. Within each group the patients were randomly assigned to one behaviorally-focused method (exposure), one physiologically-focused method (applied relaxation) and a waiting-list control group. The patients were treated individually in eight sessions. The between-group comparisons showed that both exposure and applied relaxation were significantly better than the waiting-list condition. Furthermore, exposure yielded better results than applied relaxation for the behavioral reactors, while applied relaxation was better than exposure for the physiological reactors. The improvements were maintained at a follow-up assessment 14 months after the end of treatment. The results support the hypothesis that greater effects are achieved when the method used fits the patient's response pattern than when it does not.  相似文献

The purpose of the present study was an attempt to describe clinical symptoms in terms of physiological reactions and negative cognitions experienced by phobic patients. A total of 267 clinical phobic patients divided among blood phobia, small animals phobia, dental phobia, claustrophobia, social phobia and agoraphobia, participated in the study. The patients within each phobic category were separated into a Conditioned and an Indirect Acquisition group, based on their answers to a set of specific questions concerning the etiology of the phobia. All patients rated (0–4) how intensively they experienced 11 specified physiological reactions and 10 negative cognitions when confronted with their phobic situation in vivo. A mean score was calculated for each item within each group, and an item rank-order hierarchy was set up for each group. Differences between items within each hierarchy were statistically evaluated by one-way ANOVAs and Turkey's HSD-tests. Results showed particular idiosyncratic patterns of responding for the blood phobic, agoraphobic and social phobic groups as well as several commonalities among all the groups concerning activation of specific physiological reactions and negative cognitions. A more fine-grained analysis of the data is best made by direct visual inspection of the figures in this paper.  相似文献

We investigated the relationship between components of rumination, brooding and reflection, and autobiographical remembering by testing whether voluntary and involuntary rehearsal mediated rumination-related variation in the sensory-affective and metacognitive features of memory experience. We focused on achievement and failure memories as both are goal-related events, yet they represent distinct experiences in terms of valence and functionality. For failure memories, brooding was associated with intense recollection and reduced psychological distance. Brooding was related to enhanced distance of achievements, indicating the disruptive effects of brooding on remembering. Although reflection attenuated the recollective experience for both achievement and failure memories, it brought achievement memories to a subjective closer past. Structural equation modelling demonstrated the mediating role of involuntary remembering on the pattern of remembering experience.  相似文献

The purpose of this study was to evaluate Denizli midwives’ self-reported knowledge of genetic diseases and genetic counseling. Data was collected on forms that obtained information about midwives approaches to basic genetics, genetic disorders, and genetic counseling (response rate = 70.1%). The highest response rate of midwives describing themselves as “knowledgeable” about basic genetic information was for mitosis and meiosis with 4.8%, about genetic disorders was for phenylketonuria with 61.1%, and about genetic counseling was for recommending ultrasonography during pregnancy with 98.1%. The source for basic genetics information for 56.4% of participants was in their school level classes. None of the midwives felt that they had sufficient knowledge about genetic counseling or screening and 76.4% would like to attend an educational course. Even though the midwives have recognized their knowledge deficit they occasionally give genetic counseling. As a result of this study a genetics course is planned for midwives so they can actively participate in the prevention and early diagnosis of genetic diseases.  相似文献
