conclusions there was a decrease in cognitive function, including attention, visual memory, naming, and executive function, as well as psychomotor function among residents of department of anesthesiology and intensive care, faculty of medicine, universitas indonesia, who underwent 12 working hours. results cognitive stimulation” test revealed statistically significant decrease at sequential ima...
AIMS To establish the norms for the letter-cancellation task-a psychomotor performance task. MATERIALS AND METHODS Eight hundred nineteen school students were selected in the present study in an age range between nine and 16 years (M = 12.14; SD = 1.78 years). Subjects were assessed once for the cancellation task. RESULTS Both age and sex influenced performance on the SLCT; therefore, corre...
An experiment to assess psychomotor performance before and after forward-facing (-Gx) impact was conducted using the AFAMRL Horizontal Decelerator Facility. There were 10 volunteer subjects who participated in 50 tests at 4 impact levels (0 G or sham, 8 G, 10 G, and 12 G). Two initial head positions were explored at the highest impact level. The manikin psychomotor task, a complex reaction time...
background: noise is defined as unwanted or meaningless sound that apart from auditory adverse health effects may distract attention from cues that are important for task performance. human performance is influenced by many job-related factors and workplace conditions including noise level. objective: to study the effect of noise on human performance. methods: the participants included 40 healt...
conclusion the results of the study suggest that biofeedback training may help to train stressed athletes to acquire a control over their psychophysiological processes, thus helping an athlete to perform maximally. results two way repeated measure anova was used to simultaneously compare within and between group differences. response time, concentration, heart rate variability, respiration rate...
As part of a larger study, data on arithmetic computation and motor coordination were obtained from 206 twin pairs. The twins were measured once before and three times after ingesting a standard dose of alcohol. Previous analyses ignored the time-series structure of these data. Here we illustrate the application of simplex models for the genetic analysis of covariance structures in a repeated-m...
This study assessed the effect of intravenous alcohol infusions on psychomotor impairment and compared it with that of alcohol administered orally. Comparisons were made between three European drink-driving limits of blood alcohol concentration (BAC) (20, 50 and 80 mg 100 ml-1) and an oral dose of alcohol 0.75 mg kg-1. Twelve volunteers, aged 22-34 yr, were recruited. At targets of 20, 50 and a...
The role of illicit drugs on driving, and particularly of cannabis and driving, is the object of increasing awareness. While there is increasing evidence of their effect on psychomotor performance and increased risk of involvement in traffic accidents, limited information is available concerning factors that can predict the likelihood of driving under the influence of cannabis. The present stud...
BACKGROUND Imaging studies show that placebo enhance release of dopamine in the mesolimbic and mesocortical tracts. Dopamine in these areas are involved in attention and working memory function. PURPOSE We wanted to investigating the effect of placebo on psychomotor function and working memory capacity. METHOD 31 medical students participated in this single blind, crossover trial. Choice re...
OBJECTIVE To examine the variability in psychomotor task performance in women in reference to the menstrual cycle. METHODS One hundred and eighty young women with spontaneous regular menstrual period of 30 days duration and 20 young men were assessed in the Department of Pharmacology, College of Medicine, Al-Mustansiriya University, Baghdad, Iraq during 2003. RESULTS Women had significantly...
