Attention and memory for threat in panic disorder   总被引:1,自引:0,他引:1  
Recently, information processing paradigms have been utilized to explore the role of attentional and memory processes in the maintenance of clinical anxiety disorders. The present study extended these data using a dual-task paradigm to assess attentional vigilance and a cued recognition task to evaluate short-term memory effects in Panic Disorder (PD). Twenty PD patients and 20 normal controls completed a computerized task wherein they read aloud one of a pair of rapidly presented words (primary task) while simultaneously attempting to detect a small probe that appeared adjacent to one of the words (secondary task). Eighty stimulus words were chosen to represent four categories: physical panic-related threat, social threat, positive-emotional, and neutral. Reaction time and accuracy in detecting the probe were assessed, as well as psychophysiological responding (heart rate, skin conductance, EMG). Following task completion, a cued recognition task was administered to examine short-term memory of task stimuli. Results indicated that PD patients exhibited slower reaction times relative to normal controls during presentation of physical panic-related threat and positive-emotional stimuli. A similar trend emerged for social threat stimuli, although the PD and control samples responded similarly to neutral stimuli. No group differences were found on the cued recognition measure or psychophysiological responding during task performance. The data are discussed in terms of possible implications for cognitive models of PD.  相似文献

A previous study demonstrated that naming of repeated colors, objects, letters, and numbers (RAN test) was performed more slowly by dyslexic than by nondyslexic learning disabled children, whereas both groups were slower than controls. A test eliminating the vocal response and requiring “cancellation” of selected verbal targets distinguished the two learning disabled groups from each other only when the targets were triads of numbers or letters, the dyslexic group performing more slowly. Compared even with triad target selection, however, dyslexic children were relatively more impaired on rapid naming (RAN), suggesting a specific relationship of reading to speech or the greater mobilization of language functions which speech requires.  相似文献

This article reports on a content analysis of television commercials (n?=?434) aired during prime-time on US general networks (ABC, NBC, CBS, and FOX) and an African American niche station (Black Entertainment Television—BET) in 2002. Targeted group/nontargeted group representations are explored in relation to depictions of domestic/romantic fulfillment and agency. The findings reveal that although the majority of characters on all stations studied were male and White, the niche station did provide a venue for some positive gender representations. Specifically, characters on BET were more likely to be portrayed as respected and as sex-objects. Findings demonstrate that although the niche station BET represents a venue for minority voices, it is also a source of problematic representations of gender.  相似文献

Acute responses to smoking are influenced by nicotine and by nonpharmacological factors such as nicotine dose expectancy and sensory effects of smoke inhalation. Because negative mood increases smoking reinforcement, the authors examined whether these effects may be altered by mood context. Smokers (n=200) participated in 2 sessions, negative or positive mood induction, and were randomized to 1 of 5 groups. Four groups comprised the 2x2 balanced placebo design, varying actual (0.6 mg vs. 0.05 mg yield) and expected nicotine dose (expected nicotine vs. denicotinized [denic]) of cigarettes. A fifth group was a no-smoking control. Smoking, versus not smoking, attenuated negative affect, as well as withdrawal and craving. Negative mood increased smoking reinforcement. However, neither actual nor expected nicotine dose had much influence on these responses; even those smokers receiving and expecting a denic cigarette reported attenuated negative affect. A follow-up comparison suggested that the sensory effects of smoke inhalation, but not the simple motor effects of smoking behavior, were responsible. Thus, sensory effects of smoke inhalation had a greater influence on relieving negative affect than actual or expected nicotine intake.  相似文献

Eighty-one listeners defined by three age ranges (18-30, 31-59, and over 60 years) and three levels of musical experience performed an immediate recognition task requiring the detection of alterations in melodies. On each trial, a brief melody was presented, followed 5 sec later by a test stimulus that either was identical to the target or had two pitches changed, for a same-different judgment. Each melody pair was presented at 0.6 note/sec, 3.0 notes/sec, or 6.0 notes/sec. Performance was better with familiar melodies than with unfamiliar melodies. Overall performance declined slightly with age and improved substantially with increasing experience, in agreement with earlier results in an identification task. Tempo affected performance on familiar tunes (moderate was best), but not on unfamiliar tunes. We discuss these results in terms of theories of dynamic attending, cognitive slowing, and working memory in aging.  相似文献

Scholars have long argued that popular consumer culture is both producer and product of social inequality, but few detailed empirical studies have explored the ways that advertising imagery simultaneously constructs stereotypes of race and gender. This article reports on a content analysis of television commercials (n = 1699) aired on programs with high ratings for specific target audiences from 1992 to 1994. Characters in the television commercials enjoy more prominence and exercise more authority if they are White or men. Logistic regression analyses indicate that images of romantic and domestic fulfillment also differ by race and gender, with women and Whites disproportionately shown in family settings and in cross-sex interactions. In general, 1990s television commercials tend to portray White men as powerful, white women as sex objects, African American men as aggressive, and African American women as inconsequential. The authors suggest that these commercial images contribute to the perpetuation of subtle prejudice against African Americans by exaggerating cultural differences and denying positive emotions. Results are discussed in relation to the segmentation of media markets and possibilities for social change.  相似文献

Using secondary analysis, this study compared the characteristics of 1,763 parolees with substance abuse problems who successfully completed a post incarceration drug treatment program with those who did not. Those who completed the program were more likely to be women who had not used drugs 30 days before program admission, had fewer prior treatment experiences, remained in the program longer, and had secured employment and stable living arrangements by the time of discharge. Implications for treatment and program development are discussed.  相似文献

Background Primary care physicians often treat older adults with Generalized Anxiety Disorder. Objective To estimate physician diagnosis and recognition of anxiety and compare health service use among older adults with GAD with two comparison samples with and without other DSM diagnoses. Methods Participants were 60+ patients of a multi-specialty medical organization. Administrative database and medical records were reviewed for a year. Differences in frequency of health service use were analyzed with logistic regression and between-subjects analysis of covariance. Results Physician diagnosis of GAD was 1.5% and any anxiety was 9%, and recognition of anxiety symptoms was 34% in older adults with GAD. After controlling for medical comorbidity, radiology appointments were increased in the GAD group relative to those with and without other psychiatric diagnoses, χ2 (2, N = 225) = 4.75, p < .05. Conclusions Most patients with anxiety do not have anxiety or symptoms documented in their medical records.  相似文献

Most studies of inattentional blindness—the failure to notice an unexpected object when attention is focused elsewhere—have focused on one critical trial. For that trial, noticing the unexpected object might be a result of random variability, so that any given individual would be equally likely to notice the unexpected object. On the other hand, individual differences in the ability to perform the primary task might make noticing more likely for some individuals than for others. Increasing the difficulty of the primary task has been shown to decrease noticing rates for both brief static displays (Cartwright-Finch & Lavie, 2007) and dynamic monitoring tasks (Simons & Chabris, 1999). However, those studies did not explore whether individual differences in noticing arise from differences in the ability to perform the primary task. For our Experiment 1, we used a staircase procedure to equate primary task performance across individuals in a dynamic inattentional blindness task and found that the demands of the primary task affected noticing rates when individual differences in accuracy were minimized. In Experiment 2, we found that individual differences in primary task performance did not predict noticing of an unexpected object. Together, these findings suggest that although the demands of the primary task do affect inattentional blindness rates, individual differences in the ability to meet those demands do not.  相似文献

Despite the efficacy of evidence-based psychotherapies (EBP) for posttraumatic stress disorder (PTSD) and efforts to disseminate them, only 6–13% of veterans seeking care through the Veterans Affairs health care system receive these treatments. EBPs such as prolonged exposure (PE) and cognitive processing therapy (CPT) are exposure-based treatments. Provider and patient fears regarding the tolerability of exposure-based treatments likely impede their delivery and completion. The present study utilized qualitative interviews with 23 veterans who completed at least eight sessions of either PE or CPT to elicit firsthand accounts of veterans’ experiences in these EBPs. Results suggest that while a minority of veterans reported initial symptom worsening, the majority of veterans reported positive experiences and felt that, despite being stressful, these EBPs were “worth it.” Most veterans discussed thoughts of discontinuing treatment prematurely, but stated that adherence was encouraged by their commitment to finishing, desperation for relief, therapist/group support, and family support. Veterans believed exposure made an important contribution to symptom improvement, as did greater self-understanding and changing negative or unhelpful beliefs. These findings indicate veteran satisfaction with PE and CPT, and may assist providers to develop strategies to increase adherence and treatment completion.  相似文献
