Objective: It is unknown whether aging affects predecisional processing, that is, gathering information and evaluating options before making a decision. Here, we investigated information sampling in mild @entity303 of @entity195 (DAT) and healthy aging by using the Information Sampling Task (IST). Method: In a first investigation, we compared @entity1 with mild DAT (n = 20) with healthy controls (n = 20) on the IST and several neuropsychological background tests. In a second investigation, healthy older adults (n = 30) were compared with younger adults (n = 30) on the IST and executive-function tasks. Results: Results of the first investigation demonstrated that, in the IST, @entity1 gathered significantly less information, made riskier and less accurate decisions, and showed less reward sensitivity relative to controls. We found a significant correlation between performance on the IST and performance on tests of verbal fluency, working memory, and recognition in @entity1 but not in controls. Results of the second investigation indicated a largely similar performance pattern between healthy older adults and younger adults. There were no significant correlations for both groups between the IST and executive-function tasks. Conclusions: There are no relevant changes with healthy aging in predecisional processing. In contrast, mild DAT significantly affects predecisional information sampling. Thus, the problems shown in @entity1 with mild DAT in decision making might be related to the @entity1 ' difficulties in predecisional processing. Decision-making performance in mild DAT might be improved by helping the @entity1 at a predecisional stage to gather sufficient information and evaluate options more accurately.
