Psychomotor Epilepsy and Aggressive Behavior

Abstract: The literature states that patients with psychomotor epilepsy are prone to aggressive acting-out behavior. Of 150 epileptic patients whose seizures were photographed, 42 had ictal psychomotor automatisms and 15 had postictal psychomotor attacks. There was no instance of ictal or postictal aggression in this study. When there was danger of aggressive behavior, it could promptly be averted by abandoning restraint efforts. To define the characteristics of the aggression prone individual, 700 charts were reviewed; 34 patients were found who had committed aggressive acts. The profile of the aggression-prone individual which emerged was that of a young man of lower-than-average intelligence with a history of behavioral difficulties dating back to school age and who did not have strong religious ties. Presence or absence of psychomotor epilepsy was not a relevant variable.

African Infant Precocity and Some Social Influences during the First Year

Abstract: In African infants precocious in both mental and motor test performance during the first year of life, environmental factors contributed at least 25% to test score variance. Even in the first year, therefore, social factors must be considered in evaluation of psychological development of these infants.

Competency based learning: technology, management, and design

Abstract: This volume looks at the management of learning and breaks the subject down into four main areas. The first is planning, in which the task is analysed, needs are identified and objectives are written. The second is organising, in which teaching tatics, class size, audiovisual aids and strategies are selected. The third is leading, in which student motivation, teaching strategy, older students and psychomotor skills are discussed. The final part is controlling, in which evaluation of courses and learning is discussed as well as the concept of managing by learning objectives.

Effects of antihistamines, chlormezanone and alcohol on psychomotor skills related to driving

Abstract: The effects of diphenhydramine, meclastine, and chlormezanone, alone or in combination with alcohol, on psychomotor skills related to driving have been investigated in 300 healthy volunteers. A choice reaction test and two coordination tests were employed. — Diphenhydramine caused sedation, partly independent of the dose, and slightly impaired psychomotor performance. Some subjects were exceptionally sensitive to diphenhydramine induced impairment of skills. It enhanced the effects of alcohol. — Meclastine did not impair psychomotor performance. A 1.5 mg dose did not enhance the effects of alcohol, but 3 mg did, although it was less potent than 50 mg of diphenhydramine. — Chlormezanone 200 mg had a relaxing effect which became apparent as a shortened reaction time at 30 min. Chlormezanone 400 mg did not affect psychomotor performance, nor did it enhance the effects of alcohol on psychomotor skills.

Drug interaction on psychomotor skills related to driving: hypnotics and alcohol.

Abstract: The effects of nitrazepam, diazepam, ethinamate, and bromvaletone administered the previous evening were studied the next morning on 260 volunteer students and policemen. Psychomotor skills were measured by a choice reaction test, two coordination tests, and an attention test. Nitrazepam impaired the psychomotor performance of middle aged subjects. Diazepam alone showed minimal effects but interacted with alcohol in a different way from nitrazepam. Ethinamate slightly improved co-ordinative skills but impaired attention. Its interaction with alcohol was very mild. Bromvaletone alone showed minimal effects on psychomotor performance but a strong interaction with alcohol. Since all the hypnotics studied interacted with alcohol taken the next morning, any of these combinations is deleterious for driving.

Effects of Environmental Color on Two Psychomotor Tasks

Abstract: A popular viewpoint holds that various hues will have differential effects on activation level and psychomotor performance. To test the performance hypothesis 125 Ss performed two psychomotor tasks...

Effects of Social Facilitation upon Females' Performance of two Psychomotor Tasks

Abstract: The purpose of this investigation was to test the effects of the presence of an audience as compared to a co-action group setting during performance of two different psychomotor tasks. Social facilitation theory predicts identical social influences resulting from either condition and does not take into account the nature of the task performed. Ninety female subjects were randomly selected from a voluntary population of 238. Thirty subjects were then randomly assigned to each of three treatment conditions: alone, audience, and co-action. All subjects performed three trials on each task: hand-steadiness and manual dexterity. Separate ANOVA was completed for performance on each task. When a significant F ratio was obtained the Tukey Method for multiple comparisons of means was applied. The results showed some support for the hypothesis that the effects of an audience and a co-action group setting are not identical. The co-action group performed significantly better than the audience group on both ta...

Testing Psychomotor Performance During Sustained Acceleration

Abstract: : Recommendations, developed for the USAF School of Aerospace Medicine (SAM), concern a human psychomotor performance task which could be used to monitor, on a moment-to-moment basis, an operator's ability to perform satisfactorily during sustained acceleration stress. First, a survey was made of the literature on performance testing during G-stress, and/or on the relationship between physiologic and behavioral changes during acceleration. Next, an experimental program was planned and carried out, in which candidate tasks were evaluated under conditions of hypoxia and alcohol intoxication. Final recommendations were then made for: a running memory task to measure a decrement in cognitive skills; and an automated testing system, for installation on the SAM centrifuge, suitable not only for the recommended test but also for many other diversified tasks.

Effects of Concurrent Negative Feedback On Performance of Two Motor Tasks. Working Paper Number Six.

Abstract: The effects of stress on state anxiety and on HR of male high school Ss were investigated using two psychomotor tasks. In the Stress Condition, Ss received negative feedback about performance; Ss in the Nonstress Condition were given rest intervals. Ss in the two conditions showed similar pretask, p> .05, A-State and HR measures. However, during the tasks the groups showed differing regression lines. The Nonstress Group maintained the same A-State level across the tasks with increased HR occurring as a result of the motor task. The Stress Group increased in A-State and HR measures. The two groups were significantly different, p<.01, in all within-task measures. The Stress Group performed better on the two motor skill tasks.

Relationship between social deprivation and aspects of psychomotor performance in middle adolescence.

Abstract: Though the depressed physical and nutritional status of the deprived groups in our society is historically well documented from both the imagina tive (Dickens, 1854) and journalistic (Chadwick 1842) points of view, very few investigations of a scientific nature have been conducted in this area which include objective motor performance measures in their design; the bulk of the available research literature is concerned with socio-occupational or regional differences as related to body size, par ticularly with regard to difference in height and weight (Meredith, 1951; Clements and Pickett, 1952, 1954; Scottish Council for Research in Education, 1953; Clements, 1953). It is the intention of this paper to call attention to aspects of the psychomotor condition of impoverished children by considering whether a socially determined standard of nutritive deficiency is significantly related to aspects of this condition in addition to the characteristics of height and weight. As a subsidiary we are interested in assessing the differential contribution, if any, of these 'physical' variables to this relationship before and after certain 'environmental' variables are held constant. While it is true that poverty, reproductive failure, and inadequate nutrition are components of a synergistic interaction, each being mutually rein forcing elements in a complex network of influences associated with the 'disadvantaged', their adverse effects on physical growth and development are probably greatest when such growth would normally be maximal. Consequently one of the most productive periods for assessing whether a socially determined standard of nutritive deficiency is significantly related to the physical/motor characteristics of the individual is that stage of the development cycle, termed middle adolescence, wherein occurs the adolescent growth spurt (Tanner, 1962).
