Decision making under uncertainty in a quasi realistic binary decision task – An fMRI study

摘要: Abstract Approaching real life decision making through Quasi Realistic Decision Making may increase the ecological validity of experiments. This could help narrow gap between laboratory settings and observations in world contexts thus allow for generalization results to everyday life. A binary task with quasi realistic context stimuli was created investigate neural processing certain uncertain making, using functional Magnetic Resonance Imaging. On basis behavioral data (consistency decisions identical contexts), trials were identified. allowed comparing conditions, contrasting each condition a low level baseline (i.e., trial fixation dot). Conjunction analysis contrasts uncertainty versus certainty indicated large overlap network recruitment distributed bilateral middle frontal, medial inferior parietal, occipito-temporal, medio-temporal areas, cingulate cortex. While basic principles comparable, direct contrast revealed activation foci frontal parietal areas. The approach common which is modulated by uncertainty.
