Popular Abstract in Swedish

Konventionella neuropsykologiska test, och begåvningstest, tar sällan hänsyn till att begåvningen "filtreras" genom individens personlighet vid utförandet av uppgifterna. Två lika begåvade personer (dvs med samma IQ) kan utföra samma test på helt olika sätt beroende på t.ex att den ena är impulsiv och snabb och den andra eftertänksam och försiktig. Detta medför skillnader både i slutresultat, och i de specifika strategivariabler som numera kan mätas med stor noggrannhet vid datoriserad testning, t.ex. Automated Psychological Test system APT-PC, (Levander, 1988). Föreliggande studie beskriver framtagandet av strategivariabler och index i dessa test, och validering av dessa mot externa kriterier...

Automated Psychological Test system APT-PC, (Levander, 1988). Föreliggande studie beskriver framtagandet av strategivariabler och index i dessa test, och validering av dessa mot externa kriterier såsom personlighetsskalor och val av yrke. På sikt kan mätning av strategivariabler vid testning ersätta subjektiva mått av både kapacitet och personlighet, vilket kan vara av intresse dels i rekryteringssammanhang, men också i kliniska sammanhang, t.ex. med hjärnskadade patienter.

Abstract
"Personality determines very largely the use a person makes of his intellectual gifts" (Eysenck, 1988). Computerization of neuropsychological tests has made possible a detailed analysis of both quantitative and qualitative aspects of a person´s test performance. Factor analyses of test data generally bring out two main factors of performance: speed and accuracy, representing both the intellectual capacity, and the subject´s preference for one over the other, probably reflecting general traits in the personality. A conceptualization of strategy indices in the Perceptual Maze test in terms of serial vs global processing and impulsive vs consistent test behavior, and their relation to personality questionnaire data was studied. A PET... (More)
"Personality determines very largely the use a person makes of his intellectual gifts" (Eysenck, 1988). Computerization of neuropsychological tests has made possible a detailed analysis of both quantitative and qualitative aspects of a person´s test performance. Factor analyses of test data generally bring out two main factors of performance: speed and accuracy, representing both the intellectual capacity, and the subject´s preference for one over the other, probably reflecting general traits in the personality. A conceptualization of strategy indices in the Perceptual Maze test in terms of serial vs global processing and impulsive vs consistent test behavior, and their relation to personality questionnaire data was studied. A PET activation study during performance of the Perceptual Maze test and a sham maze task revealed no specific maze-planning activation, nor any relations between solution strategy and laterality, nor any sex differences. In students, however, sex differences in performance and strategy were found, women being slower and more cautious than men. A comparison of skill, strategy, and personality data in air force pilot recruits and randomly selected conscripts showed that pilots were skilled and fast, but not impulsive in tests, despite high scores in impulsivity related scales. Criminal subjects were found to be less flexible than other groups, not changing strategy when conditions changed, in the k-test of selective attention. In the final study strategy and performance indices were validated against personality questionnaire data and choice of profession. In conclusion, strategy evaluation in computerized tests may be a valid and objective way to assess ´personality in action´ in normal subjects, but may also be of interest in clinical settings.
