    ABSTRACT Researchers in different paradigms have concentrated on different narrow slices of the decision making domain, such as choice in classical decision theory or recognition in naturalistic research. We distill a more comprehensive and fruitful conception based on graded commitments to action at different levels of specificity and scope. Three pathways to commitment -Choice, Matching, and Reassessment -differ in both their starting points (initial commitment status), the questions they pose, and the normative rationales they confer on conclusions (desirability of consequences, fit between situation and rule, and successful performance, respectively). Levels of uncertainty, understood as obstacles or affordances for commitment, apply within each mode, accounting for cognitive strategies that vary from quick and accurate to slow and exploratory in each mode. Implications for cognitive engineering include adaptation of decision aids and training to both fundamental differences and the need for seamless transitions among decision modes and uncertainty levels
