Potentials and limitations of cognitive treatments for obsessive-compulsive disorder

Exposure and response prevention (ERP) is a well-established treatment for obsessive-compulsive disorder (OCD). However, it is not completely effective for many patients, and some do not benefit from or tolerate this treatment. Over the past 3 decades there has been growing interest in using cognitive interventions, either as adjuncts or alternatives to exposure-based treatments such as ERP, to address these shortcomings. Cognitive therapy and cognitive behavior therapy for OCD have both demonstrated greater efficacy than no treatment at all, and appear to have a lower incidence of dropout than ERP. Unfortunately, however, for the average OCD patient, cognitive interventions have not improved treatment efficacy; that is, cognitive interventions, either alone or combined with ERP, are no more effective than ERP alone. Reasons for this disappointing result are considered, and indications for the use of cognitive interventions are discussed. Future research directions are suggested in order to evaluate more fully the merits of, and indications for, cognitive methods for treating OCD.     

Healing and Psychotherapy: The Pentecostal Tradition

This paper explores the practice of healing in the Pentecostal movement. The practice of healing has a long tradition in Pentecostal practice. The meaning of divine healing and what could be components of a theology of healing are examined. It is important for pastoral counselors, pastors, and chaplains to be aware of the importance of divine healing for Pentecostal clients.     

Does negative priming reflect inhibitory mechanisms? A review and integration of conflicting views

Negative priming has traditionally been viewed as a reflection of an inhibitory mechanism of attention. However, recent accounts have suggested that negative priming does not reflect inhibitory mechanisms. Rather, slowed reaction times on negative priming trials are either due to retrieval of incompatible response tags or of mismatching perceptual information, or due to extra processes needed to distinguish past from present information. In contrast, it is proposed that there is no firm evidence to discount inhibition models. In fact, although retrieval processes can be implicated in negative priming effects, understanding of these requires consideration of the inhibitory processes involved in selecting information for goal-directed behaviour.     

Visual Search Remains Efficient When Visual Working Memory is Full

Many theories of attention have proposed that visual working memory plays an important role in visual search tasks. The present study examined the involvement of visual working memory in search using a dual-task paradigm in which participants performed a visual search task while maintaining no, two, or four objects in visual working memory. The presence of a working memory load added a constant delay to the visual search reaction times, irrespective of the number of items in the visual search array. That is, there was no change in the slope of the function relating reaction time to the number of items in the search array, indicating that the search process itself was not slowed by the memory load. Moreover, the search task did not substantially impair the maintenance of information in visual working memory. These results suggest that visual search requires minimal visual working memory resources, a conclusion that is inconsistent with theories that propose a close link between attention and working memory.     

African Americans and High Blood Pressure: The Role of Stereotype Threat

We examined the effect of stereotype threat on blood pressure reactivity. Compared with European Americans, and African Americans under little or no stereotype threat, African Americans under stereotype threat exhibited larger increases in mean arterial blood pressure during an academic test, and performed more poorly on difficult test items. We discuss the significance of these findings for understanding the incidence of hypertension among African Americans.
