Impact of cognitive-behavioral therapy for panic disorder on comorbidity: a controlled investigation

This study examined the effects of cognitive-behavioral therapy (CBT) for principal panic disorder with or without agoraphobia, on comorbidity in 30 individuals (16 female). To test the hypothesis that improvements in co-existing conditions were not due to spontaneous fluctuations across time, patients receiving immediate CBT were compared to those assigned to wait list (n = 11). Results indicated clinician-rated severity of comorbid specific phobia declined significantly following immediate CBT compared to no change after wait list. The number of patients without comorbidity of any severity increased after immediate CBT, with no such increase following wait list. However, the groups did not differ in the frequency of additional diagnoses or overall severity of comorbidity. In the total sample, results indicated reductions in comorbidity by 9-month follow-up, with marked declines in the severity of comorbid generalized anxiety disorder (GAD), social and specific phobia. Our findings suggest that targeted CBT for panic disorder has beneficial effects on comorbidity over the longer term and that some of its immediate effects exceed those due to the passage of time alone.     

Interference effects in the picture-word stroop task

Line drawings of common objects with an embedded three-or four-letter word or scrambled word were presented either to the right or left visual field. Subjects were to name the line drawing of a common object as fast and as accurately as possible. Reaction times and response accuracy were recorded and analyzed. Percent errors were significantly higher when a line drawing with a word was presented in the right visual field than in the left visual field. Sex of subject was not significant. This finding is analogous to results found when the color-word Stroop task is used.     

Stroop interference: Hemispheric difference in Chinese speakers

Some recent studies have demonstrated that the processing of color is favored by the nondominant hemisphere in English-speaking subjects. Single Chinese logographs in Japanese- as well as Chinese-speaking subjects are similarly favored. In the present study, it was hypothesized that more Stroop interference would occur in the nondominant hemisphere because the two processes involved in the Stroop effect (i.e., reading logographs and naming colors) are possibly localized in that hemisphere in Chinese-speaking subjects. Eighteen right-handed Chinese-English bilinguals were used as subjects. There were three conditions in each visual field: Interference, reading, and naming. Each slide was presented for 150 msec preceded by a fixation dot. Subjects were asked to verbally report as fast and as accurately as possible either the color words or the color names, depending upon the condition. Reaction times and error rates were analyzed. As expected, more Stroop interference was obtained when color words were presented in the left visual field. This result is in direct contrast with that of Y-C. Tsao, T. Feustel, and C. Soseos 1979, Brain and Language, 8, 367–371. In that study, more Stroop interference was obtained when the materials were presented in the right visual field in English-speaking subjects.     

On processing chinese ideographs and english words: some implications from Stroop-Test results.

When Chinese subjects tried to name the color of characters which represented conflicting color words, they showed markedly greater interference than did English speaking readers performing an English version of the same task. This effect cannot be attributed to bilingualism among the Chinese subjects since bilinguals in other languages show smaller Stroop-interference than monolingual controls. Instead, there may be some fundamental differences in the perceptual demands of reading Chinese and English which can have widespread implications for human information processing.     

The Effects of Person-Environment Fit and External Locus of Control on Organizational Affective Commitment: a Study of Immigrant Wives in Taiwan

The National Immigration Agency of Taiwan reported that, by 2014, more than 498,000 immigrant spouses were registered in Taiwanese households, 91 % of which was female. Immigrant wives are now a significant part of Taiwanese society, and they are an important aspect of the labor force in Taiwan’s economy. However, they face major challenges in the workplace, which influences their work outcomes, results in a reduced labor force for enterprises, and increases societal costs. This pioneering study employed the person-environment fit and locus of control concepts from the organizational behavior field to address this issue. A sample of 130 immigrant wives from Indonesia and Vietnam living in Taiwan was surveyed. The results of a hierarchical regression analysis found that immigrant wives’ person-job fit and person-supervisor fit significantly influenced their affective commitments to their workplaces. An external locus of control significantly weakened the relationship between person-environment fit and affective commitment. The contributions and implications of the study results were discussed.     

Behavioral avoidance tests and disgust in contamination fears: distinctions from trait anxiety

Much of the existing literature examining the role of disgust is limited to specific phobia. Recent research has begun to examine the role of disgust in contamination fear, a subtype of obsessive-compulsive symptoms. Through the use of behavioral avoidance tasks (BATs), the current study was designed to examine the role of disgust in people with contamination fears, with attention to distinguishing high and low trait anxiety. From a large screening of undergraduate students, three groups were formed based on their level of contamination fear and level of trait anxiety: contamination fearful ( n = 12 ), high-trait anxiety ( n = 11 ), and low trait anxiety ( n = 15 ). Subjects were asked to engage in six different BATs corresponding to six domains of disgust (food, animals, body products, body envelope violations, death, and sympathetic magic). One-way analysis of variance (ANOVA) showed significant differences between the contamination fearful group and the high trait anxiety group on the animal and sympathetic magic BATs. Significant differences on the food, animal, body envelope violations, and death BATs were also found between the contamination fearful group and the low-trait anxious group. The findings modestly support the importance of disgust in contamination fears. Implications for the study of disgust in contamination fear are provided.     

Brand signal quality of products in an asymmetric online information environment: An experimental study

Previous research regarding the effectiveness of brand name signalling has focused mainly on when and how marketers will recover costs. This study reverses this trend by examining how buyers may interpret signals via the brand name, the effectiveness of signalling via brand name in terms of buyer‐value perspectives and how buyers' reactions to signals affect sellers' decisions to adopt a signalling strategy. Signalling theory and concepts from consumer‐based branding research are used to suggest how to evaluate the effectiveness of signalling via brand name in the context of the consumer market – a market in which information is asymmetric. Findings from a number of repeated experiments, using the methodology of experimental economics, demonstrate that the function of a brand fluctuates according to which market conditions prevail for brand and price, the extent of brand differentiation and the magnitude of brand‐building costs.

A Unified,Transdiagnostic Treatment for Adolescents With Chronic Pain and Comorbid Anxiety and Depression

Chronic pain disorders represent a significant public health concern, particularly for children and adolescents. High rates of comorbid anxiety and unipolar mood disorders often complicate psychological interventions for chronic pain. Unified treatment approaches, based on emotion regulation skills, are applicable to a broad range of emotional disorders and suggest the possibility of extending these interventions to chronic pain and pain-related dysfunction. This case report describes the use of a unified protocol for treatment of an adolescent boy with chronic daily headache and social anxiety and an adolescent girl with whole body pain and depression. Following weekly, 50-minute individual treatment sessions, the boy demonstrated notable improvement in emotional symptoms, emotion regulation skills, somatization, and functional disability. The girl showed some improvement on measures of anxiety and depression, although there appeared to be a worsening of pain symptoms and somatization. However, both patients demonstrated improvement over follow-up. This case study illustrates the potential utility of a unified treatment approach targeting pain and emotional symptoms from an emotion regulation perspective in an adolescent population.
