The role of emotional information and internal motivation in older adults’ decision-making process was explored in this review. The role was embodied in the following four aspects: self-related of tasks influence the invest of cognitive resources; older adults pay more attention to emotional information related to decisions, give preference to positive information and are sensitive to the way of decision-making tasks described. Future research should consider more direct ERPs evidence. For example, use ERPs technique to monitor older adults’ decision-making in order to discriminate the information types that older adults used and their emotional and motivational responses. This method could contribute to precisely discern the effect of emotional information and internal motivation on information search. Furthermore, future research should also study the neutral mechanism of older adults’ decision-making process from the perspective of neurobiology.
