Cognitive behaviour therapy for the management of obsessive-compulsive disorder

Current research reflects conflict regarding best practice in the treatment of obsessive-compulsive disorder (OCD). The. present study reports on the psychological treatment of a 54-year-old woman diagnosed with OCD, and follows the implementation of pharmacological treatment. The study utilises both exposure and response prevention (ERP) and cognitive therapy (CT), although there was no attempt to compare these approaches in an experimental design. Measures of avoiding and neutralising behaviours were taken on three occasions across treatment. Measures were also taken of intrusive thoughts, appraisal of responsibility, and effective challenging, both across treatment and at follow-up. The results indicate that gains were made in addition to those reported following the implementation of medication. The results also suggest that the addition of CT to exposure and response prevention facilitates the extinction of neutralising behaviours.

An exploratory study of gendered differences in young tourists perception of danger within London

This paper studies young tourists' perception of danger within the urban holiday environment of London, England. The study of perceived danger is important not only in its own right, but also because of the influence it may have on use of leisure spaces and times. This research assesses gender and group composition differences in perception of danger, addressing the relatively neglected issues of men's perception and the relationship between the genders. For the purpose of this paper 'danger' was assessed by studying how safe, relaxed, vulnerable, threatened, and at risk people felt while in London. The study found a number of similarities and differences between the men and women studied, in terms of how they perceived danger and their group composition during the day and nigh-time. These results indicate that gender may not be the only influence on perception and behaviour, and that men and women should not be regarded as-homogenous cohorts. (C) 2001 Elsevier Science Ltd.

The effect of videoconferencing on the depth perception of observers

The ability of the human eye to perceive depth was measured using a specially designed instrument. Visual acuity and both monocular and binocular stereoacuity were measured when viewing the instrument directly and via a videoconferencing link. Ten subjects with an average age of 32.5 years (range 24-50) took part in the study. The group mean visual acuity using both eyes under normal test conditions was -0.04 logMAR (Snellen 6/5) compared with 0.18 logMAR (Snellen 6/10) for the video-link. The mean stereoacuity using both eyes was 37 (SD 18) under normal test conditions. When a videoconferencing link was used, the mean stereoacuity fell to 1218 (SD 1203) using one eye and to 1651 (SD 1419) using both eyes. The ability to perceive depth remotely via a video-link was significantly decreased compared with normal test conditions.
