Surgery of a high-grade carotid stenosis is evidence-based stroke prevention. Also cognitive effects are reported after carotid endarterectomy (CEA): both deterioration and improvement, the former attributed to perioperative complications and the latter often to learning effect. By imaging, brain perfusion and diffusion changes were shown in subjects with a high-grade stenosis undergoing CEA. We wanted to find out if the cognition of patients undergoing CEA display postoperative worsening or true improvement in association with findings in serial MR imaging. The patients had a poorer overall cognition than healthy matched controls. The cerebral hemisphere ipsilateral to the stenosis had higher diffusion and more sluggish perfusion leading to perfusion deficits. These asymmetries were abolished by CEA. Postoperatively, the patients showed a trend for cognitive worsening, most often attentional, but over months, the group performance improved similarly to the controls. Still, lower baseline perfusion was associated with a greater cognitive improvement, most clearly in executive functions. Consequently, despite the risk for transient decline, true cognitive benefit by CEA seems possible. 相似文献

This paper illustrates the empirical investigation of social representations by means of photographs as stimulus material and the technique of correspondence analysis to study the resulting data. The research was part of a campaign carried out to promote organ donation in Malta. The study tries to find out whether a public communication campaign could change perceptions. Five focus groups were held before the campaign and another five, two months after the campaign. Part of the data collected through these focus groups was analysed using correspondence analysis. The results showed that before the campaign, donors were generally perceived to be either young or important people or public personalities. After the campaign, donors were perceived more to be ordinary family people, educated, generous and religious. On the other hand, before the campaign, non‐donors were seen as conservative, uncouth and uncaring, whereas after the campaign non‐donors were generally perceived to be older, uninformed and uneducated people.

This multi‐method research linked the Big Five personality dimensions to aggression in early adolescence. Agreeableness was the personality dimension of focus because this dimension is associated with motives to maintain positive interpersonal relations. In two studies, middle school children were assessed on the Big Five domains of personality. Study 1 showed that agreeableness was associated with both indirect and direct aggression. In addition, the link between agreeableness and aggression was strongest for direct strategies. Study 2 examined the hypotheses that agreeableness predicts social cognitions associated with aggression, peer reports of direct aggression, and teacher reports of adjustment. Agreeableness predicted peer reports of aggression and social cognitions associated with aggression. In addition, aggression mediated the link between agreeableness and adjustment. Results suggest that of the Big Five dimensions, Agreeableness is most closely associated with processes and outcomes related to aggression in adolescents. Aggr.

Commentators have suggested that the conflict-resolution literature has progressed slowly. Another paradigm that may be used to generate experimentally testable hypotheses comes from the common law. Four scenario-based experiments are reported that were used to test hypotheses from a common law called adverse possession. One of three disputes involving a lost child, an automobile, and a patent were described in scenarios that subjects read and then rated using identical scales across scenarios. The scales measured the degree of ownership, neglect of the original owner, investment of the adverse possessor, and welfare of the disputed object. Whether the seizure of the disputed object was open and notorious and was continuous were statistically significant, while the results of the amount of time the possession was held by the adverse possessor was not. The common law has been shaped by judicial decisions that mirror social evolution and may reflect variables that people and nations can use to resolve conflicts. 相似文献

Happy, surprised, disgusted, angry, sad, fearful, and neutral facial expressions were presented extrafoveally (2.5° away from fixation) for 150 ms, followed by a probe word for recognition (Experiment 1) or a probe scene for affective valence evaluation (Experiment 2). Eye movements were recorded and gaze-contingent masking prevented foveal viewing of the faces. Results showed that (a) happy expressions were recognized faster than others in the absence of fixations on the faces, (b) the same pattern emerged when the faces were presented upright or upside-down, (c) happy prime faces facilitated the affective evaluation of emotionally congruent probe scenes, and (d) such priming effects occurred at 750 but not at 250 ms prime–probe stimulus–onset asynchrony. This reveals an advantage in the recognition of happy faces outside of overt visual attention, and suggests that this recognition advantage relies initially on featural processing and involves processing of positive affect at a later stage. 相似文献

Emotional scenes were presented peripherally (5.2° away from fixation) or foveally (at fixation) for 150 ms. In affective evaluation tasks viewers judged whether a scene was unpleasant or not, or whether it was pleasant or not. In semantic categorisation tasks viewers judged whether a scene involved animals or humans (superordinate-level task), or whether it portrayed females or males (subordinate-level task). The same stimuli were used for the affective and the semantic task. Results indicated that in peripheral vision affective evaluation was less accurate and slower than animal/human discrimination, and did not show any advantage over gender discrimination. In addition, performance impairment in the peripheral relative to the foveal condition was greater or equivalent for affective than for semantic categorisation. These findings cast doubts on the specialness and the primacy of affective over semantic recognition. The findings are also relevant when considering the role of the subcortical “low route” in emotional processing. 相似文献

Anxiety sensitivity (AS) refers to a person’s tendency to fear anxiety-related symptoms due to the belief that they have harmful
consequences. The Childhood Anxiety Sensitivity Index (CASI) is a well accepted operationalization of the AS construct in children and adolescents. This study evaluated the factor structure,
gender stability and psychometric properties of the CASI, modified to a 5-point scale, in a sample of Croatian children and
adolescents (N = 1,679). Exploratory and confirmatory analysis and a Schmid-Leiman solution confirmed the multidimensional and hierarchical
structure of the CASI, which consisted of three lower-order factors and a single higher-order factor. Further, the modification
of the CASI to a 5-point scale resulted in higher reliability, while maintaining acceptable levels of factor stability and
validity. 相似文献

Anxiety sensitivity (AS) refers to a person's tendency to fear anxiety-related symptoms due to the belief that these symptoms may have harmful consequences. The most widely used operationalization of AS in adults is the Anxiety Sensitivity Index (ASI). The factor structure, gender stability, and psychometric properties of the ASI in a sample of Croatian adults (N = 984) were evaluated. Results confirm the multidimensional and hierarchical structure of the ASI, which consisted of three lower-order factors (Physical Concerns, Psychological Concerns, and Social Concerns) and a single higher-order factor, AS. Furthermore, the achievement of normative scores for the ASI in a Croatian adult sample demonstrates the cross-national stability of the ASI. Reliability coefficients for the ASI, Physical Concerns, and Psychological Concerns are high and satisfactory in the total sample and for both genders. Overall, the results confirmed the cross-national stability, gender stability, reliability, and validity of the ASI in a sample of Croatian adults. 相似文献

Relationship quality is a strong predictor of health outcomes, and individuals with social anxiety disorder (SAD) report increased interpersonal impairment. However, there are few studies testing the effect of SAD on friendships and it is thus unclear whether there are behavioral differences that distinguish friendships in which a target individual has SAD from friendships in which the target individual does not have SAD. We tested for differences in the provision and receipt of support behaviors as a function of having a SAD diagnosis and accounting for comorbid depressive symptoms. Participants with SAD (n = 90) and their friends engaged in support conversations that were coded using the Social Support Interaction Coding System. Structural equation modeling revealed some differences between participants and friends when accounting for depression. Specifically, friends of participants with SAD and comorbid depression engaged in fewer positive helper behaviors than the friends of participants who did not have SAD or comorbid depression. Additionally, dyads in which the primary participant had SAD engaged in more off-task behaviors. Results suggest that SAD does not result in global interpersonal impairment, but that receipt of positive support behaviors from friends may differ as a function of SAD and comorbid depression. Interpersonal interventions aimed at increasing adaptive friendships and aspects of CBT that target subtle avoidance (e.g., safety behaviors) may be useful in facilitating more satisfactory relationships for these individuals. 相似文献
