Wegner's seminal investigations of effects of thought suppression on later thought frequency have had a significant impact on recent approaches to understanding emotional disorders characterized by the occurrence of persistent, repetitive, unwanted thoughts. Thought suppression has now been implicated as a etiological and/or maintaining factor in(More)
Leading models of obsessive-compulsive disorder (OCD) implicate thought suppression as a key factor in the escalation and persistence of the disorder. This experiment examined the effects of suppression on the frequency of obsessional thoughts in 50 individuals with a primary diagnosis of OCD, and also investigated the effects of participants' appraisals(More)
Glucose turnover and its regulation were studied during and after two identical bouts of intense exhaustive exercise separated by 1 h to define differences in response. Six lean young postabsorptive male subjects exercised at approximately 100% maximal O2 uptake (3.7 +/- 0.3 l/min) for 13.0 +/- 0.7 min for the first (EX1) and 13.2 +/- 0.8 min for the second(More)
Intense exercise is associated with a marked stimulation of glucose production (Ra), a somewhat smaller increment in its utilization (Rd) (and therefore hyperglycemia), large increases in plasma catecholamines, and moderate hyperglucagonemia. The hyperglycemia increases in recovery and is accompanied by hyperinsulinemia. Because these adaptations are unique(More)
To explore the role of perfectionism across anxiety disorders, 175 patients with either panic disorder (PD), obsessive compulsive disorder (OCD), social phobia, or specific phobia, as well as 49 nonclinical volunteers, completed two measures [Frost, R. O., Marten, P., Lahart, C., & Rosenblate, R., (1990). The dimensions of perfectionism. Cognitive Therapy(More)
Wegner's (1994, Psychological Review, 101, 34-52) research on the paradoxical effect of thought suppression has been incorporated into contemporary cognitive-behavioural models of obsessive-compulsive disorder. However, findings on the effects of thought suppression on thought frequency have been inconsistent and few studies have actually examined the(More)
Individuals with social phobia often hold erroneous beliefs about the extent to which others experience symptoms of social anxiety and the ways in which others evaluate people who appear to be anxious. The purpose of this study was to: (a) provide normative data on the frequency with which individuals in a nonclinical sample experience particular symptoms(More)
Attentional biases for threatening stimuli have been implicated in the development of anxiety disorders. However, little is known about the relative influences of trait and state anxiety on attentional biases. This study examined the effects of trait and state anxiety on attention to emotional images. Low, mid, and high trait anxious participants completed(More)
Hyperglycemia with accompanying hyperinsulinemia occurs after brief, greater than 85% maximum oxygen consumption exercise to exhaustion in normal subjects and persists up to 60 min of recovery. To determine the importance of endogenous insulin secretion during and after intense exercise, responses to exercise of lean fit male post-absorptive(More)
The present study reports on the development and preliminary validation of a 52 item self-report instrument designed to assess intrusive thoughts, images and impulses that are similar to the aggressive, sexual and disease-related thinking characteristic of clinical obsessions. Two hundred and ninety-three students completed the Obsessive Intrusions(More)
