Cognitive models propose that self‐focused attention (SFA) interacts with fear of negative evaluation to maintain social anxiety. Thus, the effect of SFA on anxiety would be expected to be specific to those with existing social concerns. However, much research suggests that the effect of SFA on anxiety occurs across anxiety levels. Manipulations of attention focus have been criticised for (1) lack of ecological validity and (2) eliciting fear of negative evaluation directly. The present study examined the role of SFA in social anxiety using an ecologically valid procedure that did not elicit fear of negative evaluation directly. Self‐reported anxiety was assessed among high and low socially anxious individuals under conditions of SFA or external‐focused attention. The manipulation successfully altered focus of attention but did not directly affect fear of negative evaluation or self‐reported anxiety. Taken together with the findings of previous studies, the results suggest that focusing on internal physiological states per se does not increase self‐reported social anxiety, and that self‐focus that does not have an explicitly evaluative dimension does not elicit social anxiety. The findings have implications for approaches to reducing social anxiety through reducing SFA.  相似文献

The present study represents one of the first comparisons of the long-term effectiveness of traditional cognitive behavior therapy (i.e., Beckian cognitive therapy; CT) and acceptance and commitment therapy (ACT). One hundred thirty-two anxious or depressed outpatients were randomly assigned to receive either CT or ACT, and were assessed at posttreatment (n = 90) and at 1.5-year (n = 91) follow-up. As previously reported, the two treatments were equivalently effective at posttreatment according to measures of depression, anxiety, overall (social/occupational/symptom-related) functioning, and quality of life. However, current results suggest that treatment gains were better maintained at follow-up in the CT condition. Clinical significance analyses revealed that, at follow-up, one-third more CT patients were in the clinically normative range in terms of depressive symptoms and more than twice as many CT patients were in the normative range in terms of functioning levels. The possible long-term advantage of CT relative to ACT in this population is discussed.  相似文献

Attention bias modification (ABM) protocols aim to modify attentional biases underlying many forms of pathology. Our objective was to conduct an effect size analysis of ABM across a wide range of samples and psychological problems. We conducted a literature search using PubMed, PsycInfo, and author searches to identify randomized studies that examined the effects of ABM on attention and subjective experiences. We identified 37 studies (41 experiments) totaling 2,135 participants who were randomized to training toward neutral, positive, threat, or appetitive stimuli or to a control condition. The effect size estimate for changes in attentional bias was large for the neutral versus threat comparisons (g = 1.06), neutral versus appetitive (g = 1.41), and neutral versus control comparisons (g = 0.80), and small for positive versus control (g = 0.24). The effects of ABM on attention bias were moderated by stimulus type (words vs. pictures) and sample characteristics (healthy vs. high symptomatology). Effect sizes of ABM on subjective experiences ranged from 0.03 to 0.60 for postchallenge outcomes, –0.31 to 0.51 for posttreatment, and were moderated by number of training sessions, stimulus type, and stimulus orientation (top/bottom vs. left/right). Fail-safe N calculations suggested that the effect size estimates were robust for the training effects on attentional biases, but not for the effect on subjective experiences. ABM studies using threat stimuli produced significant effects on attention bias across comparison conditions, whereas appetitive stimuli produced changes in attention only when comparing appetitive versus neutral conditions. ABM has a moderate and robust effect on attention bias when using threat stimuli. Further studies are needed to determine whether these effects are also robust when using appetitive stimuli and for affecting subjective experiences.  相似文献

In previous studies we have shown that a General Factor of Personality (GFP) occupies the apex of the hierarchy of personality as well as the apex of the personality disorders in the same way that g, the general factor of mental ability, occupies the apex in the organization of cognitive abilities (Rushton & Irwing, 2011). In a critique, Muncer (2011) re-analyzed one of our data sets and concluded there was no evidence for a GFP. He also argued against the evolutionary theory we had proposed for the origin of the GFP. In this rejoinder I rebut Muncer’s conclusion and describe how directional selection can explain the GFP.  相似文献

Selection of new geographies in which to expand is a key decision for businesses aspiring to go beyond the opportunities in the existing markets. The conventional approaches of market selection can only provide a set of systematic steps for problem solving without considering the relationships between the decision factors. Decision models based on statistical techniques are able to examine the relationship between decision factors but are unable to effectively assist decision makers in identifying the most promising market, particularly in terms of prioritizing across decision factors. Analytic Hierarchy Process (AHP) is a commonly used approach for choosing alternatives by prioritizing across multiple decision factors. The typical AHP modelling requires knowledge of criteria and/or alternatives along with their relative weights, generally elicited from field experts. Quite often, firms encounter situations where decision makers are aware of only the overall objective and a set of earmarked geographies for setting up market locations while being relatively unaware of decision criteria and relative weights. This precludes using AHP to identify promising market locations. This paper conceptualizes a market selection decision model that integrates AHP with statistical modelling techniques to identify the attractive market locations for the purpose of expansion. The model first uses principal component analysis and multiple regression to determine significant decision criteria and their weights. Thereafter, it applies AHP to prioritize the market locations across the decision criteria. This integrative approach is illustrated for identifying the attractive locations in rural markets for a steel firm in India. The major advantage of this approach is that unlike the existing models, it works in situations when firms have not enough knowledge about factors for evaluating alternative market locations. Another key advantage of the proposed model is that of economizing resources for data collection on variables representing decision factors. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Psychological distance in terms of its purpose as a psychological adjustment is currently not well understood. Some researchers claim that psychological distance serves as an emotion regulator, while others argue that psychological distance has the reverse effect, leading to cognitive avoidance and rumination. To elucidate upon this discrepancy, we propose that a complementary matching of psychological distance to one's habitual psychological distance perspective may lead to better emotion regulation when compared to the original perspective (i.e. fixing on either psychological immersion or distance). This study hypothesizes that a complementary matching of psychological distance to one's habitual perspective generally leads to better emotion regulation; specifically, individuals with high avoidant attachment, who habitually distance themselves from their experiences, may benefit from psychological immersion, while individuals with high anxious attachment, who habitually immerse themselves in their experiences, may benefit from psychological distancing. A total of 83 participants completed measures of adult attachment orientations; read a conflict scenario, triggering their attachment systems; and then rewrote that scenario using designated pronouns, thereby employing psychological immersion or psychological distance. Participants in the self‐immersed condition were asked to write from the first‐person perspective, whereas those in the self‐distancing condition were asked to write from the third‐person perspective. The results support our hypothesis of a complementary matching of psychological distance and habitual perspective.  相似文献

Even at subclinical levels, anxiety and depression are associated with impaired cognitive control. It is unclear, though, to what extent these deficits reflect a common underlying dysfunction. Using a non-affective hybrid masked prime-Simon task, we obtained several measures of within- and between- trial inhibitory behavioral control in 80 young, healthy volunteers, together with measures of their anxiety and depression levels. Neither depression nor anxiety affected low-level within-trial control, or any of the between-trial control measures. However, increased levels of depression, but not of anxiety, were associated with impaired high-level within-trial control (increased Simon effect). Results indicate that depression, but not anxiety, impairs voluntary online response-control mechanisms independent of affective content.  相似文献

Abstract

The growing ill-health in Sweden is related to the crisis of the welfare state and to globalization and the expansion of a new virtual reality affecting the conceptualization of time and space, as well as to wider areas of human interaction, thinking, and ethical judgment. Fear and anxiety are emotional states of mind that have widespread effects on an individual level as well as on the whole of society.  相似文献

Background: Inflammatory Bowel Disease (IBD) impacts quality of life (QoL). Psychological factors influence the course of the disease and should be targeted for intervention.

Methods: Our study was a prospective, randomised control trial. Fifty-six outpatients were randomly chosen and allocated to a treatment group or a waiting-list control group. Treatment group patients attended three relaxation-training sessions and received an audio disc for home practice. Evaluations performed pre and post-treatment: state anxiety was assessed with the State-Trait Anxiety Inventory, QoL with the IBD Questionnaire. The Visual Analogue Scale assessed pain, depression, stress and mood. Patients completed a symptom monitoring diary. The control group's symptoms were monitored without study-related treatment.

Results: Thirty-nine subjects completed the study and were included in the data analysis. Following the relaxation-training intervention, the treatment group's (n?=?18) measured results showed a statistically significant improvement as compared to the control group (n?=?21) (time by treatment interaction): anxiety levels decreased (p?<?0.01), QoL and mood improved (p?<?0.05), while levels of pain and stress decreased (p?<?0.01).

Conclusions: Findings indicate IBD patients may benefit from relaxation training in their holistic care. New studies as well as further investigation of the subject are warranted.  相似文献
