Acceptance and commitment therapy (ACT) has never been tested for patients with chronic fatigue. We aimed to test if a 3.5‐week ACT rehabilitation program for patients with chronic fatigue improved quality of life (QoL), fatigue, and psychological flexibility. Further, to test if improvements in QoL and fatigue were associated with improvement in psychological flexibility, and if psychological flexibility explained variance above and beyond maladaptive cognitions typically targeted in CBT for fatigue. Patients (n = 140) who had been on sick leave > 8 weeks due to chronic fatigue received a 3.5‐week non‐controlled inpatient rehabilitation program based on ACT. A physician and a psychologist examined the patients, assessing medication use and SCID‐I diagnoses. Patients completed questionnaires about somatic complaints, psychological complaints, and maladaptive cognitions before and after treatment. At post‐treatment, patients reported improved QoL (p < 0.001; g = 1.07) and less fatigue (p < 0.001; g = 1.08), but not increased psychological flexibility (p = 0.6). Changes in psychological flexibility was associated with improved QoL, but not fatigue, in hierarchical regression analyses. When adjusting for other cognitions, changes in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility, were associated with improved QoL and fatigue. The ACT‐based treatment improved QoL and reduced fatigue for patients with chronic fatigue with large effect sizes. Improvement was associated with a reduction in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility. 相似文献

The attentional blink (AB) refers to the finding that the perception of the second of two targets (T2) is impaired when presented in close temporal proximity to the first target (T1). An exception to this deficit occurs when T2 immediately follows T1, an effect referred to as lag 1 sparing. So far, it has been unclear whether the AB is location specific or nonspatial in nature. Most demonstrations of an AB across different locations have shown an absence of lag 1 sparing, due to accompanying spatial switch costs. This means that the AB pattern itself may be explained through such switch costs. In this study, to minimize spatial switch costs, attention was made to move continuously across multiple locations by aid of a cue. An AB across different locations was found, including lag 1 sparing. We conclude that the AB and lag 1 sparing are not tied to a location but represent a central deficit, in line with current theory. 相似文献

Mental images: Specific or general,personal or impersonal? 总被引:1,自引:0,他引:1
Tore Helstrup Cesare Cornoldi & Rossana Debeni 《Scandinavian journal of psychology》1997,38(3):189-197
In three experiments the relation between visual images classified in terms of the four categories of personal, impersonal, specific, and general images was explored. The results showed that subjects were able to generate all types of images, with personal images being the easiest to recall. Personal images, together with general images, were the image types being easiest to integrate with one another. Overall, the observations suggested the existence of two imagery dimensions: specific-general, and personal-impersonal. Memory was found to be best for personal images. Personal images turned out to be easier to integrate in memory than specific images. The findings were discussed in terms of different image generation models. 相似文献

The evolutionary background for cognition and awareness is currently under ardent scrutiny. Poikilothermic vertebrates such as teleost fishes are capable of classical conditioning and have long-term memories, but it remains unknown to what degree such capabilities are associated with affective states. Here, we investigate whether the concept of frustration may apply to Atlantic salmon. In mammals, this paradigm comprises the omission of an expected reward (OER), which elicits behavioural and physiological coping responses (e.g. aggression and stress reactions). Six groups with 200 fish in each were conditioned to associate a flashing light (CS) with feeding. Conditioning over 22?days led to a change from aversion to attraction to the CS. Subsequently, 3 groups served as control, and 3 groups were subjected to an OER paradigm for 9?days, in which the expected food reward was delayed for 30?min during two out of three daily meals. Compared to controls, OER groups displayed higher levels of aggression and more heterogeneous growth rates, indicating a more pronounced social hierarchy. Cortisol levels did, however, not differ between treatments and both groups responded similarly to acute stress. These results indicate that teleost fishes, like mammals, respond aggressively to OER. The capacity to respond behaviourally to frustrating conditions thus likely reflects an adaptive response to environmental unpredictability, which has been conserved throughout vertebrate evolution. 相似文献

The purpose of this paper was to examine predictors of an interest in liposuction among women with eating problems. A questionnaire was sent to 3500 women aged 18-35 years, whereof 378 of 1861 responders screened positively on eating problems. Assessments included sociodemographic status, social network, physical exercise, attitudes towards cosmetic surgery, teasing history, body dysmorphic disorder-like symptoms, body image, self-esteem, personality, interpersonal attachment and emotional distress. Fifty-two percent reported an interest in liposuction, which was independently predicted by appearance orientation, appearance evaluation, being critical/quarrelsome, teasing history, wish for a better relationship with father, low education and being unmarried. Predictors differed somewhat from those previously found in the general population. Considering that our sample consisted of women with self-reported eating problems, the association between liposuction and eating behaviors should be further examined in a sample of patients with a formal eating disorder diagnosis. 相似文献

The goal of the present paper is to construct a formal explication of the pluralistic ignorance explanation of the bystander effect. The social dynamics leading to inaction is presented, decomposed, and modeled using dynamic epistemic logic augmented with ‘transition rules’ able to characterize agent behavior. Three agent types are defined: First Responders who intervene given belief of accident; City Dwellers, capturing ‘apathetic urban residents’ and Hesitators, who observe others when in doubt, basing subsequent decision on social proof. It is shown how groups of the latter may end in a state of pluralistic ignorance leading to inaction. Sequential models for each agent type are specified, and their results compared to empirical studies. It is concluded that only the Hesitator model produces reasonable results. 相似文献
