Fears related to anxiety sensitivity (AS)-illness/injury sensitivity, fear of negative evaluation, and fear of pain-may have important theoretical associations with intolerance of uncertainty (IU). In separate investigations, AS and IU have been independently related to the same anxiety-related psychopathology. AS and IU seem to share a basis in fearing unknown, potentially harmful consequences; however, their inter-relationship remains uncertain. IU regarding a specific stimulus, a physical sensation for example, may result in a variety of interpretations and responses, including the catastrophic appraisals that characterize AS. The association between AS and IU was examined in a sample of 293 undergraduates. Results of confirmatory factor and correlation analyses suggest the two constructs are related, but nonetheless independent. It appears that IU may be a required component of catastrophic misappraisals while being an important construct related to fear and anxiety in its own right. Future research directions and potential applications are discussed.  相似文献

Suicide risk is thought to increase with a greater potential for activation of suicide-related schemas. Suicide schemas are less likely to be activated with reductions of emotional range associated with certain negative symptoms of schizophrenia. The study tested whether suicide risk would increase in patients with recent onset schizophrenia with increased potential for suicide schema activation as indicated by lower levels of specific negative symptoms that reflected emotional reactivity, namely emotional withdrawal and blunted affect. A logistic regression analysis of baseline data of 278 recent onset schizophrenic patients with a measure of suicide behaviour as the dependent variable and negative symptoms, delusions, hallucinations, depression, gender, episode, ethnicity, education, age, duration of untreated psychosis and substance use as independent variables was carried out. Emotional withdrawal, but not blunted affect was significant and negatively associated, and depression positively associated with suicide behaviour. There was evidence to indicate that restricted emotions are associated with reduced suicide risk as predicted.  相似文献

Past research shows that violent video game exposure increases aggressive thoughts, angry feelings, physiological arousal, aggressive behaviors, and decreases helpful behaviors. However, no research has experimentally examined violent video game effects on physiological desensitization, defined as showing less physiological arousal to violence in the real world after exposure to video game violence in the virtual world. This experiment attempts to fill this gap. Participants reported their media habits and then played one of eight violent or nonviolent video games for 20 min. Next, participants watched a 10-min videotape containing scenes of real-life violence while heart rate (HR) and galvanic skin response (GSR) were monitored. Participants who previously played a violent video game had lower HR and GSR while viewing filmed real violence, demonstrating a physiological desensitization to violence. Results are interpreted using an expanded version of the General Aggression Model. Links between desensitization, antisocial, and prosocial behavior are discussed.  相似文献

We hypothesized that a tendency towards abstract, general and decontextualized processing is a cognitive distortion that causally contributes to symptoms of depression. This hypothesis predicts that training dysphoric individuals to become more concrete and specific in their thinking would reduce depressive symptoms. To test this prediction, participants with stable dysphoria (scoring ≥ 14 on BDI-II at 2 consecutive weekly assessments) were randomly allocated in an additive design either to an active intervention control consisting of relaxation training or relaxation training plus concreteness training. Concreteness training involved repeated mental exercises designed to encourage more concrete and specific thinking about emotional events. Both interventions involved a training session and then repeated daily use of compact disc recordings for 7 days. Relaxation training plus concreteness training resulted in significantly greater decreases in depressive symptoms and marginally significantly greater decreases in state rumination than relaxation training alone. These findings suggest the potential value of concreteness training as a guided self-help intervention for mild-to-moderate depressive symptoms.  相似文献

Inferences from faces can predict success. This may be particularly important for women, who are often evaluated by their appearance. Here 170 northeastern U.S. undergraduates judged personality traits or leadership ability from the faces of all 20 U.S. Fortune 1,000: 2006 female chief executive officers (CEOs) and we compared these ratings to the same trait ratings made for male CEOs in a previous study. After controlling for cues important for female leaders (attractiveness, affect, age, and masculinity/femininity), ratings of competence and leadership predicted the amount of profits that the CEOs’ companies made and ratings of dominance predicted the amount of individual compensation that the CEOs received. CEOs’ success is therefore related to their facial appearance regardless of target and perceiver gender.  相似文献

We have designed and implemented a low-cost digital system using closed-circuit television cameras coupled to a digital acquisition system for the recording of in vivo behavioral data in rodents and for allowing observation and recording of more than 10 animals simultaneously at a reduced cost, as compared with commercially available solutions. This system has been validated using two experimental rodent models: one involving chemically induced seizures and one assessing appetite and feeding. We present observational results showing comparable or improved levels of accuracy and observer consistency between this new system and traditional methods in these experimental models, discuss advantages of the presented system over conventional analog systems and commercially available digital systems, and propose possible extensions to the system and applications to nonrodent studies.  相似文献

One of the reasons integrated care has not become a dominant service delivery model is the unmet training agenda. This article argues that the typical mental health professional is not trained to adequately address the challenges of integrated care. To insure competency both a macro and clinical training agenda are needed. At the macro-level, mental health professionals need to understand healthcare economics and basic business principles as any integrated care service delivery system is embedded and driven by economic forces. Integrated care practitioners also need some basic business skills to understand these forces and to create and manage a financially viable system, given the future flux of the system. Traditional mental health professionals also do not have the clinical skills to implement integrated care. Integrated care is not simply placing a traditionally trained mental health professional and letting them practice specialty mental health in a medical setting. Thus, the special skills needed in integrated care are enumerated and discussed. Finally, a new degree program is described as it is time given the huge need and advantages of integrated care to develop specialty training in integrated care.  相似文献

Recent evidence suggests the existence of multiple cognitive mechanisms that support the general cognitive ability factor (g). Working memory and processing speed are the two best established candidate mechanisms. Relatively little attention has been given to the possibility that associative learning is an additional mechanism contributing to g. The present study tested the hypothesis that associative learning ability, as assessed by psychometrically sound associative learning tasks, would predict variance in g above and beyond the variance predicted by working memory capacity and processing speed. This hypothesis was confirmed in a sample of 169 adolescents, using structural equation modeling. Associative learning, working memory, and processing speed all contributed significant unique variance to g, indicating not only that multiple elementary cognitive processes underlie intelligence, but also the novel finding that associative learning is one such process.  相似文献
