Exposure to an acute naturalistic stressor induces both psychological and physiological changes in humans. The two studies reported here explored the impact of exposure to an acute naturalistic stressor on state anxiety, working memory and HPA axis activation (salivary cortisol). In both experiments, ten healthy male participants were exposed to an acute(More)
RATIONALE Neuroimaging evidence suggests that ecstasy-related reductions in SERT densities relate more closely to the number of tablets typically consumed per session rather than estimated total lifetime use. To better understand the basis of drug related deficits in prospective memory (p.m.) we explored the association between p.m. and average long-term(More)
Although it is widely known that memory is enhanced when encoding and retrieval occur in the same state, the impact of elevated stress/arousal is less understood. This study explores mood-dependent memory's effects on visual recognition and recall of material memorized either in a neutral mood or under higher stress/arousal levels. Participants' (N = 60)(More)
Acute stress has been associated with changes in cognitive performance and mood, and these have been in part associated with stress-related increased release of cortisol. Both glucose and caffeine consumed in isolation have been shown to moderate cortisol response and affect cognitive performance and affect mood; however, there has been very little research(More)
BACKGROUND During emergencies maladaptive behavior can reduce survival. This study compared the effects of a basic firefighter training course on 21 volunteers (with no firefighting experience) with age and gender-matched controls. METHODS Stress reactivity (salivary cortisol and anxiety) were monitored across the course: day 1 (classroom), day 2(More)
This research explored the post-stroke cognitive ability of a 52-year male, KM, who suffered a left middle cerebral artery stroke. KM received no rehabilitation post-stroke, as clinic assessments suggested that mental functioning had returned to an acceptable level. However, KM believed that his cognitive ability had not returned to pre-stroke levels.(More)

Associative learning underpins behaviours that are fundamental to the everyday functioning of the individual. Evidence pointing to learning deficits in recreational drug users merits further examination. A word pair learning task was administered to examine associative learning processes in ecstasy/polydrug users. After assignment to either single or(More)
