Cognitive models assume that panic disorder is characterised by a tendency to misinterpret benign bodily symptoms (e.g. breathlessness) in a catastrophic fashion (e.g. suffocation). This is a central part of the cognitive model which presents a core focus for treatment. Several studies have supported this hypothesis. These studies have, however, almost always relied on self-report. In addition to susceptibility to biases (e.g. distortions of memory), a limitation of research based on verbal report is its inability to capture the spontaneous/automatic nature that is attributed to these catastrophic interpretations. The present paper reports on two experiments in which a priming procedure was used to test the hypothesis that panic disorder is characterised by spontaneous catastrophic interpretations and whether this effect is ‘specific’ to panic disorder. In line with predictions from the cognitive model, it was observed in the first experiment that the panic group demonstrated facilitated responses to trials consisting of a ‘symptom’ prime and a ‘catastrophic outcome’ target (e.g. breathlessness - suffocate). Similar effects were not observed for an anxious control group and a nonclinical control group, supporting the specificity of this effect. Interestingly, however, significant priming effects were observed for a group of mental health professionals (part of the healthy control group) who had no history of panic disorder. Subsequently, this unexpected observation was explicitly addressed in a second experiment, which confirmed the findings of Experiment 1. Together, these results suggest that associations between mental representations of benign bodily symptoms and catastrophic outcomes might develop as part of professional knowledge and experience, and should not necessarily be viewed as pathogenic. Theoretical and clinical implications are discussed. 相似文献

ABSTRACT More than a decade ago, Hansen, Harway, and Cervantes (1991) and Harway and Hansen (1993) examined mental health providers' ability to accurately perceive violence within couples presenting for therapy and to intervene in a manner that reduces risk. Alarmingly, 40% of therapists sampled failed to identify the presence of intimate partner violence (IPV) and none predicted lethality. Over a decade later, the present replication of Harway and colleagues' study was completed with the expectation that today's therapists are better prepared to identify IPV within a clinical vignette. Results show that therapists have indeed improved their ability to identify IPV. However, only one therapist accurately predicted lethality in the present study. Implications concerning IPV training for therapists are discussed. 相似文献

Whether the effects of exposure to 1 movement generalize to another dissimilar movement was investigated in 37 patients with low back pain (15 men, 22 women). Two movements were executed twice: bending forward while standing and lifting 1 leg while lying down. During each trial, baseline pain, expected pain, and experienced pain were recorded. Similar ratings for perceived harm were obtained. Analyses revealed an initial over prediction of pain, but after exposure the overprediction was readily corrected. This exposure effect did not generalize toward another dissimilar movement. These results were only characteristic for patients with catastrophic thinking about pain. Low pain catastrophizers did not overpredict pain. There were no effects of exposure on perceived harm. Exposure may profitably be conceived of as the learning of exceptions to a general rule. 相似文献

Metabotropic glutamate receptor 7 (mGluR7) is expressed in brain regions implicated in emotional learning and working memory, and previous behavioral experiments indicated contributions of mGluR7 to various complex behaviors. In the present study, we investigated the specific effects of mGluR7 deletion on a variety of conditioning paradigms that model crucial neurocognitive and psychopathological behavioral phenomena. Null-mutant mGluR7−/− mice displayed defects during scheduled appetitive conditioning, acquisition and extinction of appetitive odor conditioning, extinction of response suppression-based conditioned emotional responding (CER), acquisition of discriminative CER, and contextual fear conditioning. mGluR7−/− animals were slower to acquire the association between a conditioned stimulus and a positive or negative reinforcer, but eventually reached similar performance levels to their wildtype littermates. Notably, extinction learning of conditioned responses was slower in mGluR7−/− compared to wildtype animals. The observed delays in the acquisition of complicated stimulus associations across conditioning procedures may suggest a critical role for mGluR7 in neurocognitive functions and psychopathology. 相似文献

Because men of higher genetic quality tend to be poorer partners and parents than men of lower genetic quality, women may profit from securing a stable investment from the latter, while obtaining good genes via extrapair mating with the former. Only if conception occurs, however, do the evolutionary benefits of such a strategy overcome its costs. Accordingly, we predicted that (a) partnered women should prefer attached men, because such men are more likely than single men to have pair-bonding qualities, and hence to be good replacement partners, and (b) this inclination should reverse when fertility rises, because attached men are less available for impromptu sex than single men. In this study, 208 women rated the attractiveness of men described as single or attached. As predicted, partnered women favored attached men at the low-fertility phases of the menstrual cycle, but preferred single men (if masculine, i.e., advertising good genetic quality) when conception risk was high. 相似文献

This study examined whether consumers' use of evidence affected the price at which car salespersons offered to sell a vehicle. Two versions of a message–one containing evidence about the wholesale/invoice price of a vehicle and the other containing no evidence–were e-mailed to 134 sales managers at different Toyota dealerships. The prices offered by salespersons were collected and analyzed. Results indicated that sales managers who had received messages with evidence offered to sell the vehicle for a significantly lower price than did sales managers who received no evidence. These results, their implications, and avenues for future research are discussed. 相似文献

Unpredictability of an unconditioned stimulus (US) typically produces context conditioning in animals and humans. We modified the Martians task - a computer game measuring learning of Pavlovian associations through conditioned suppression - for assessing context conditioning in humans. One between-subjects and one within-subjects study are reported. Both experiments comprised four conditions: a predictable (Paired) condition in which the conditioned stimulus (CS) signaled the US, a neutral condition (No-US), one unpredictable condition in which the CS did not signal the US (Unpaired) and another one in which only unsignaled, temporally unpredictable USs were presented (US-only). Results showed more contextual conditioned suppression in the unpredictable conditions compared to the predictable condition. In contrast, more cued conditioned suppression occurred in the Paired condition than in the Unpaired condition. Consistent with animal research, context conditioning was increased by unpredictability. These data support the Martians task as a promising tool to extend research on human context conditioning. 相似文献

This study investigated whether the effects of exposure to one movement generalize towards another dissimilar movement in patients with low back pain. Thirty-nine patients (11 male, 28 female; mean age=43.49 yrs) were requested to perform two movements twice, i.e. bending forward and straight leg raising. During each of the four trials, baseline pain, expected pain and experienced pain were recorded. Analyses revealed that patients initially overpredicted pain, but after exposure the overprediction was readily corrected. This exposure effect did not generalize towards another dissimilar movement. The above pattern of results was only characteristic for patients reporting a high frequency of catastrophic thinking about pain. Low pain catastrophizers did not overpredict pain. The results are discussed in terms of the view that exposure may be better conceived of as the learning of exceptions to a general rule. 相似文献
