Introduction. The aim of this study was to evaluate two measures in a cognitive examination: psychomotor function and the perception of time (PT) in patients after intravenous anesthesia for endoscopic procedures. Material and Methods. We tested 23 anesthetized patients (Anesthesia Group, AG) and 17 not anesthetized patients (Control Group, CG). The Dufour Cross-Shaped Apparatus (DA) was used t...

Drug analyses were performed on 200 blood samples that were taken for alcohol analysis from road users in Tasmania. Alcohol at a concentration of above 0.5 g was found in 75% of the samples, and other drugs were found in 17% of the samples. Cannabis was the most prevalent of these other drugs: it was detected in 6% of road users; benzodiazepine drugs were detected in 5% of road users; and barbi...

PURPOSE Biofeedback is an emerging tool to acquire and facilitate physiological and psychological domains of the human body like response time and concentration. Thus, the present study aims at determining the reconstitution of psychomotor and performance skills in basketball players through biofeedback training. METHODS Basketball players (N=30) with different levels of expertise (university...

background: children with attention deficit hyperactivity disorder/developmental coordination disorder (adhd/dcd) suffer from problems associated with gross and fine motor skills. there is no effective pharmacological therapy for such patients. we aimed to assess the impact of methylphenidate (mph) on motor performance of children with adhd/dcd. methods: in this double-blind placebo-controlled,...

Individuals who work nonstandard schedules, such as rotating or night shifts, are more susceptible to workplace injuries, performance decrements, and reduced productivity. This population is also almost twice as likely to use illicit drugs as individuals working a standard day shift. The purpose of this study was to examine the effects of smoked marijuana on performance, mood, and sleep during ...

In this study we assessed the discriminative stimulus, self-reported, and performance effects of flumazenil in humans. The first group (n = 6) was trained to discriminate flumazenil (0.56 mg/70 kg i.v.) from saline and tested with flumazenil (0.10, 0.32, 0.56, and 1.0 mg/70 kg) under a two-response drug discrimination procedure. The second group (n = 8) was trained to discriminate flumazenil (0...

Numerous studies have demonstrated that motor control deficits are characteristic of patients diagnosed with schizophrenia and those at-risk for the development of the disorder. Recent advances in the quantification of motor dysfunction have confirmed this, but these methods fail to consider an important aspect of subject performance: the qualitative nature of their psychomotor dyscontrol. We r...

BACKGROUND The purpose of this study was to examine the effect of sleep deprivation on flow experience. METHODS Sixteen healthy male volunteers of mean age 21.4±1.59 (21-24) years participated in two experimental conditions, ie, sleep-deprivation and normal sleep. In the sleep-deprived condition, participants stayed awake at home for 36 hours (from 8 am until 10 pm the next day) beginning on ...
