Livsløbsudviklingen af intelligens og dens sammenhæng med centrale livsudfald

intelligens, udvikling, livsforløb, livsudfaldResumé
Denne artikels primære formål er at give læseren et overblik
med hensyn til de mere overordnede intelligensformers udvikling
over et livsløb og sekundært at undersøge, om intelligens
kan forudsige udvalgte livsudfald i bestemte aldersperioder. Vi
afklarer en række forhold, såsom hvad intelligens er, hvordan
den kan måles på tværs af forskellige livsfaser, og hvorledes
udvikling defineres som absolut forandring på gruppeniveau
eller som forandring i individuelle forskelle. Livsløbsudviklingen
i intelligens illustreres fra den tidlige barndom til den sene
alderdom via det skandinaviske normmateriale fra tre sammenlignelige
tests udviklet af den amerikanske psykolog David
Wechsler og suppleres med længdesnitsundersøgelser, der også
anvendes til at afklare den prædiktive værdi af intelligens. Udviklingen
viser sig at variere betydeligt som et resultat af intelligenstype,
udviklingstype og livsperiode. Individuelle forskelle
i intelligens har væsentlig forudsigelsesværdi med hensyn til
vigtige livsudfald i alle livets faser.
