Theories that fear results from previous traumatic experience (i.e. conditioning theories) have enjoyed widespread support for over half a century. Recent research, however, has cast doubt on the validity of these models in some specific phobias. Two studies on the etiology of height phobia have obtained findings consistent with a non-associative,(More)
Preliminary Phase I and II trials for the Lidcombe Program of early stuttering intervention have found favorable outcomes and that the treatment is safe. Although speech-language pathologists (SLPs) often need to intervene with pre-schoolers' early stuttering, many of these children will recover at some time in the future without such intervention.(More)
Using a two-lever operant drug discrimination paradigm, rats have been trained to discriminate between the administration of saline and R-(+)-HA-966 (R-(+)-3-amino-1-hydroxypyrrolid-2-one, 30 mg/kg i.p.) an antagonist at the glycine modulatory site on the N-methyl-D-aspartate (NMDA) receptor/ion channel complex. Drug-appropriate responding was not induced(More)
It is axiomatic that the capacity to experience fear is adaptive, enabling rapid and energetic response to imminent threat or danger. Despite the generally accepted utility of functional fear, the nature of maladaptive fear remains controversial. There is still no consensus about how specific fears and phobias are acquired and modulated. Two major schools(More)
A laboratory autonomic conditioning procedure was used to establish fear conditioning in human participants by pairing neutral stimuli with electric shock. Participants were also trained to make a button-press response to avoid shock. A target fear stimulus was then extinguished by presenting it without shock. The experimental group was given the(More)
The acquisition of fear of heights in an undergraduate student sample was investigated. Height-fearful (n = 50) and non-fearful (n = 50) groups were formed on the basis of extreme scores to the heights item on the FSS-III (Wolpe & Lang, Behaviour Research and Therapy, 2, 27-30, 1964). Subjects were then assessed with a battery of measures including the(More)
Stuttering is a common speech disorder that causes significant distress and may cause social maladjustment and hinder occupational potential. Treatments for chronic stuttering in adults can control stuttering by teaching the speaker to use a new speech pattern. However, these treatments are resource intensive and relapse prone, and they produce speech that(More)
UNLABELLED Previous research has not explored the Five Factor Model of personality among adults who stutter. Therefore, the present study investigated the five personality domains of Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness, as measured by the NEO Five Factor Inventory (NEO-FFI), in a sample of 93 adults seeking speech(More)
A small number of retrospective studies on the etiology of specific fears have obtained findings consistent with a biological (non-associative) explanation of fear acquisition. Unfortunately, reliance on imperfect memory to recall conditioning events which occurred many years earlier limits the conclusions that can be drawn from such data. The present(More)
Two research groups have raised the possibility that magical ideation may be a fundamental feature of obsessive-compulsive disorder. It has been proposed to underlie thought action fusion and superstitious beliefs. In this study, the Magical Ideation scale, the Lucky Behaviours and Lucky Beliefs scales, the Thought Action Fusion-Revised scale, the Padua(More)
