Slow fronto-occipital potentials, mental category, and laboratory performance
George Washington University, Human Resources Research Office, 1969 - Education - 16 pages
Physiological measures as independent indexes and predictors of attention-demanding performance are examined. Laboratory performance tasks were individually administered to pre-basic combat trainees selected on the basis of Armed Forces qualification battery (AFQT) classification. Assignment to tasks was representative with respect to mental category. Concurrent with performance on some of these tasks, slow biopotentials (mv) were recorded from the frontal and occipital emissary vein distributions on the midline scalp and were displayed on a type R dynograph. These biopotentials were also examined independently with respect to their ability to predict performance on selected tasks. (Author).
