Decision making with and without feedback: The role of intelligence, strategies, executive functions, and cognitive styles. Entscheidungsfindung mit und ohne Rueckmeldung: Die Rolle von Intelligenz, Strategien, exekutiven Funktionen und kognitiven Stilen.
Investigated the effects of intelligence, decision-making strategies, and general cognitive styles on the role of feedback in making decisions under risk. A total of 100 healthy volunteers (aged 18-62 years) were assessed with the game-of-dice task (GDT). 50 participants performed the original GDT, and the other 50 participants performed a modified GDT in which no feedback was provided. A neuropsychological test battery assessing general intelligence (Leistungspruefsystem, LPS), information processing (Farbe-Wort-Interferenztest, FWIT), and executive functioning (Trail Making Test, TMT, and Modified Card Sorting Test, MCST) as well as questionnaires assessing strategy application (Calculative-Intuitive Questionnaire, CAL/INT) and cognitive styles (German version of Rational-Experiential Inventory, REI) were administered to all participants. Results showed that participants performing the original GDT had higher net scores than those performing the modified GDT. The benefit of feedback was moderated by participants' intelligence and strategy application.
