Handedness and Psychomotor Performance
A I I E Transactions, 1970Abstract The results of three independent experiments with five diversified tasks and a total of 106 naive nonindustrial subjects tend to support the hypothesis that right-handed subjects are more likely to have a higher performance and to improve more on psychomotor tasks than do left-handed subjects.

Incentive and Practice in the Psychomotor Performance of the Elderly
Journal of Gerontology, 1978Adults aged 64 to 76 years were compared to adults aged 19 to 25 years in regard to the effects of practice and special incentive in Digit Symbol substitution performance. Differential age effects of motivation were not observed but those of practice were.

Effect of Pain on Human Psychomotor Performance
Acta Anaesthesiologica Scandinavica, 1978The effect of pain on human psychomotor performance was measured in seven healthy volunteers after an intramuscular injection of vitamin B or saline using a controlled cross‐over method. Vitamin B, causing moderate to severe pain, or painless saline was injected into the buttock at a time when the subjects' performance was impaired after an intravenous

The effects of anxiety upon psychomotor performance
Journal of Sports Sciences, 1988This paper describes an experiment which examined the effects of anxiety on choice reaction time and movement time. A balanced repeated measures design was adopted in which eight female subjects performed a six-choice visual reaction task in 'no anxiety' and 'anxiety' conditions. The anxiety condition required subjects to jump from a balcony 15 feet (4.

Electroencephalographic Studies of Skilled Psychomotor Performance
Journal of Clinical Neurophysiology, 2004Measurements based on the EEG have featured prominently in shaping present-day concepts of the neurocognitive aspects of skilled performance. The techniques include measurements of spectral power, interelectrode coherence, event-related potential components such as the P300, slow potentials, and the method of cognitive inference. The advantages offered

The effects of toluene and alcohol on psychomotor performance
Ergonomics, 1983Eight male subjects took part in four experimental sessions in an exposure chamber to assess the effects of toluene (80 p.p.m.) and alcohol (0.4 ml per kg body weight) individually and in combination on four measures of performance and also on mood. Alcohol caused a significant deterioration over the exposure session in performance on pursuit tracking ...

The effect of minor tranquilizers on psychomotor performance
Psychopharmacology, 1976The effect of a standard daily regimen of chlordiazepoxide, prazepam (a new benzodiazepine tranquilizer), and placebo were examined in a three way double-blind comparison for a sample of normal volunteers. The criteria include a limited spectrum of psychomotor functions.

Interpreting Linked Psychomotor Performance Scores
Research Quarterly for Exercise and Sport, 2013Given that equating/linking applications are now appearing in kinesiology literature, this article provides an overview of the different types of linked test scores: equated, concordant, and predicted. It also addresses the different types of evidence required to determine whether the scores from two different field tests (measuring the same construct)

Extreme Body Cooling and Psychomotor Performance
Ergonomics, 1968Abstract In a series of experiments on the effect of body cooling ( the lowering of Mean Weighted Skin Temperature (MVVST) while maintaining normal Hand Skin Temperature (HST)) on psychomotor performance, the following results were obtained. (I) Block-stringing (BS) and block-packing (BP) performance decreased linearity across levels of body cooling ...

Experimenter Expectancy Effects in Psychomotor Performance
Perceptual and Motor Skills, 1968This study investigated the effects upon psychomotor behavior of (a) student Es' expectancies about Ss performance created by the investigator, (b) information given those Es by the investigator about whether Ss were performing as expected, and (c) the cautioning of Es against bias.
