The primary goal of the study was to construct a computerised information-processing test battery to measure choice reaction time for up to and including six bits of information, to measure discrimination reaction time with regard to colour patterns and form patterns, to measure rate of information processing with regard to perceptual stimuli and conceptual reasoning, and to develop a suitable scoring system for the respective tests. The battery of tests was applied to 58 pilots. Opsomming Die hoofdoel van die studie was om ‘n gerekenariseerde inligtingverwerkingstoets-battery te konstrueer om keusereaksietyd tot en met ses bis inligting te meet, om diskriminasie-reaksietyd ten opsigte van kleurpatrone en vormpatrone te meet, om tempo van inligtingverwerking ten opsigte van perseptuele stimuli en konseptuele redenering te meet en om ‘n gepaste nasienstelsel vir die onderskeie toetse te ontwikkel. Die battery toetse is op 58 vlieëniers toegepas

The Relationship

The present report is of the relationship between digit symbol performance in schizophrenia and measures derived from a visual choice reaction-time task. The ability to ignore irrelevant visual stimuli was most closely related to digit symbol performance, other measures adding little to the predicted variance.

The purpose of this study was to investigate whether raised core temperature due to gradually increased amounts of exercise affects concentration and speed of information processing. 20 paid men, separated into groups of high (>56 ml/kg/min.) and low fitness (<46 ml/kg/min.) according to their maximal oxygen uptake (VO2max), participated in two experimental conditions (exercise and control). Concentration was measured by the Random Number Generation test of attentional deployment given every 10 min. of cycling at workloads calculated as 40, 50, 60, 70, and 80% of individual VO2max values and 10 min. after exercise cessation (exhaustion). Speed of information processing was estimated by an eight-choice reaction time/ movement time task given before and after exercise and 15 min. after exercise cessation. Core temperature was recorded at the same time individuals were administered the psychological tests. Analyses indicated that core temperatures increased significantly as a function of exercise intensity for high and low fitness groups. Correlations among the psychophysiological factors indicated that increases in core temperature were not associated with mental functioning. However, at certain core temperatures, core temperature and average choice reaction time/movement time were associated with participants' fitness.

Selection Of

Reaction time and rate of information processing are cited as critical components in the make-up of pilots. A need was identified to establish the validity of various chronometric measures in the selection of pilots. Fifty-eight military and commercial pilots and twenty non-pilots were subjected to Schepers’ Computerised Information Processing Test Battery, which measures reaction time, form discrimination time, colour discrimination time, rate of information processing (perceptual) and rate of information processing (conceptual). Five hypotheses and one postulate were formulated and tested. The results indicate that pilots could be differentiated from non-pilots with 92,3% accuracy. However, the results need to be cross-validated before they are used for selection. Opsomming Reaksietyd en tempo van inligtingverwerking word as kritieke komponente in die samestelling van vlieëniers beskou. ‘n Behoefte is geïdentifiseer om die geldigheid van verskeie chronometriese metinge in vlieënierskeuring te bepaal. Agt en vyftig militêre en kommersiële vlieëniers en twintig nie-vlieëniers is onderwerp aan Schepers se Gerekenariseerde Inligtingverwerkingstoets-battery wat reaksietyd, vormdiskriminasietyd, kleurdiskriminasietyd, tempo van inligtingverwerking (perseptueel) en tempo van inligtingverwerking (konseptueel) meet. Vyf hipoteses en een postulaat is gestel en getoets. Die resultate dui daarop dat vlieëniers met 92,3% akkuraatheid van nievlieëniers onderskei kan word. Die resultate behoort egter eers gekruisvalideer te word voordat dit finaal vir keuring gebruik kan word.
