Treating anxiety comorbid with heart disease is challenging due to (a) diagnostic overlap between anxiety and heart disease, (b) the high risk associated with ignoring chest pain symptoms and delaying seeking medical attention, (c) that cognitive-behavioral therapy based on catastrophic misinterpretation of bodily symptoms requires adaption to incorporate the element of risk, and (d) that certain interoceptive symptom induction experiments may be harmful and are therefore fraught with liability. We describe Panic Attack Treatment in Comorbid Heart Diseases (PATCHD) that is based on enhancing coping skills, performing safe interoceptive exposures and supervised exercise, and countering avoidance to reduce panic attack frequency. Pre- and posttreatment data from 18 patients shows a significant reduction in cardiovascular hospital admissions and length of stay, panic attacks, general anxiety, and depression (all p < .05). Because of the complex nature of panic disorder comorbid with heart disease, health professionals should familiarize themselves with several necessary CBT adaptions.  相似文献

This study tested James's theoretical assumption that the importance people attribute to different physical self-domains, in combination with perceived competence in those domains, influences higher order self-concepts. Data from four large samples (total N=1,831) from Sweden, Great Britain, Portugal, and Turkey were analyzed. A new version of an instrument, the Physical Self-Perception Profile-Revised (PSPP-R), was used to measure perceived competence and importance of physical self-domains, along with global self-esteem. Competence-importance interactions contributed significantly to higher order self-concepts in 3 of 4 PSPP subdomains. The same result was found in the structural equation modeling analyses and latent interaction analyses. Idiographic analyses showed that domains rated as intraindividually more important explained more global self-esteem variance compared with less important domains. In general, support for James's hypothesis was found across the different analyses. Differences between the methodology and results in the present study compared with previous studies are discussed.  相似文献

Personality traits contribute to health outcomes, in part through their association with major controllable risk factors, such as obesity. Body weight, in turn, reflects our behaviors and lifestyle and contributes to the way we perceive ourselves and others. In this study, the authors use data from a large (N = 1,988) longitudinal study that spanned more than 50 years to examine how personality traits are associated with multiple measures of adiposity and with fluctuations in body mass index (BMI). Using 14,531 anthropometric assessments, the authors modeled the trajectory of BMI across adulthood and tested whether personality predicted its rate of change. Measured concurrently, participants higher on Neuroticism or Extraversion or lower on Conscientiousness had higher BMI; these associations replicated across body fat, waist, and hip circumference. The strongest association was found for the impulsivity facet: Participants who scored in the top 10% of impulsivity weighed, on average, 11Kg more than those in the bottom 10%. Longitudinally, high Neuroticism and low Conscientiousness, and the facets of these traits related to difficulty with impulse control, were associated with weight fluctuations, measured as the variability in weight over time. Finally, low Agreeableness and impulsivity-related traits predicted a greater increase in BMI across the adult life span. BMI was mostly unrelated to change in personality traits. Personality traits are defined by cognitive, emotional, and behavioral patterns that likely contribute to unhealthy weight and difficulties with weight management. Such associations may elucidate the role of personality traits in disease progression and may help to design more effective interventions.  相似文献

National income has a pervasive influence on the perception of ingroup stereotypes, with high status and wealthy targets perceived as more competent. In two studies we investigated the degree to which economic wealth of raters related to perceptions of outgroup competence. Raters’ economic wealth predicted trait ratings when (1) raters in 48 other cultures rated Americans’ competence and (2) Mexican Americans rated Anglo Americans’ competence. Rater wealth also predicted ratings of interpersonal warmth on the culture level. In conclusion, raters’ economic wealth, either nationally or individually, is significantly associated with perception of outgroup members, supporting the notion that ingroup conditions or stereotypes function as frames of reference in evaluating outgroup traits.  相似文献

Many visual search experiments measure response time (RT) as their primary dependent variable. Analyses typically focus on mean (or median) RT. However, given enough data, the RT distribution can be a rich source of information. For this paper, we collected about 500 trials per cell per observer for both target-present and target-absent displays in each of three classic search tasks: feature search, with the target defined by color; conjunction search, with the target defined by both color and orientation; and spatial configuration search for a 2 among distractor 5s. This large data set allows us to characterize the RT distributions in detail. We present the raw RT distributions and fit several psychologically motivated functions (ex-Gaussian, ex-Wald, Gamma, and Weibull) to the data. We analyze and interpret parameter trends from these four functions within the context of theories of visual search.  相似文献

A matching-to-sample procedure was used to investigate whether 9-year-old children would demonstrate the emergence of a derived compound-sample conditional discrimination following training in four interrelated single-sample conditional discriminations and vice versa, as adults did in previous studies. In Experiment 1, three out of three children demonstrated the emergence of a compound-sample conditional discrimination following training in four single-sample conditional discriminations. In Experiment 2, two out of three children acquired a compound-sample conditional discrimination and they demonstrated the emergence of four single-sample conditional discriminations; one of them did so only after being exposed to a remediation training and testing procedure. Training variables that facilitated discrimination emergence in both directions are discussed. In general, results showed that the sophisticated learning skills that are supposedly possessed by adults are not required to demonstrate the two types of derived control under study.  相似文献

Although research on the prevention of drug use has shown that the effectiveness of programs depends partly on who applies them, the results of studies designed to clarify this issue are contradictory. This study compared the effects on smoking, in the short and medium term, of the implementation of two school-based prevention programs, depending on the type of applicator. The sample was made up of 200 seventh-grade students distributed among five experimental conditions: four of intervention, in which the programs were implemented by teachers from the school or by external psychologists, and one of control. The results show that teachers applying the Barbacana program and psychologists applying the Construyendo Salud (Building Health) program succeeded in reducing the incidence of cigarette smoking (BR-teachers 15%; C.S-psychologists 5%) and strengthening attitudes against smoking. An interaction effect between type of program and type of applicators was clearly observed.  相似文献

How little do we need to perceive 3-D shape in monocular natural images? The shape-from-texture and shape-from-shading perspectives would motivate that 3-D perception vanishes once low-level cues are disrupted. Is this the case in human vision? Or can top-down influences salvage the percept? In this study we probe this question by employing a gauge-figure paradigm similar to that used by Koenderink et al (1992, Perception & Psychophysics 52 487-496). Subjects were presented degraded natural images and instructed to make local assessments of slant and tilt at various locations thereby quantifying their internal 3-D percept. Analysis of subjects' responses reveals recognition to be a significant influence thereby allowing subjects to perceive 3-D shape at high levels of degradation. Specifically, we identify the 'medium-blur' condition, images approximately 32 pixels on a side, to be the limit for accurate 3-D shape perception. In addition, we find that degradation affects the perceived slant of point-estimates making images look flatter as degradation increases. A subsequent condition that eliminates texture and shading but preserves contour and recognition reveals how bottom-up and top-down cues can combine for accurate 3-D shape perception.  相似文献

Minority group members experience what is known as “minority stress,” by which individuals suffer stress because of their membership in stigmatized social categories. In turn, minority stress may lead to self-stigmatization. This occurs when minority group members experience a sense of shame created by the view of the majority culture and then incorporate the majority opinion into their self-image. Because it is cumulative with the stress an individual is already experiencing, self-stigmatization may become a significant stressor itself, possibly contributing to the development of suicidal ideation. A total of 609 self-identified LGBT individuals were asked to answer a battery of psychological tests to assess the interrelationships between self-stigma, perceived stress, and suicidal ideation. As expected, perceived stress predicted suicidal ideation, whereas self-stigmatization predicted both perceived stress and suicidal ideation. Structural equation modeling confirms the predictive value of self-stigma together with perceived stress in determining the suicidal ideation present among LGBT Filipinos. Self-stigma exerted a direct effect upon suicidal ideation not accounted for by perceived stress.  相似文献

Proposition 5.122 of Wittgenstein’s Tractatus (‘If p follows from q, the sense of [p] is contained in the sense of [q]’) has been the source of much puzzlement among interpreters, so much so that no fully satisfactory account is yet available. This is unfortunate, if only because the containment account of logical consequence has a venerable tradition behind it. Pasquale Frascolla’s interpretation of proposition 5.122 is based on a valid argument and one true premise. However, the argument explains sense containment only in an indirect way, leaving some crucial questions unanswered. Besides, Frascolla does not address the issue of how to make sense containment notationally perspicuous, an essential theme in Wittgenstein’s reflections. In this paper, we elaborate on Frascolla’s account by looking at the issue through the Tractarian notion of logical space. Our analysis shows that, for containment to be fully appreciated, one should adopt a negative perspective on the notion of sense (which is taken into consideration also by Wittgenstein), in line with the exclusionary theory of conceptual content, as labelled by Ian Rumfitt. Besides this, we introduce and discuss two methods—one envisaged by Wittgenstein himself—for making sense containment notationally perspicuous.  相似文献
