Developing models of decision making

Models of Deferred Decision Making

Deferred decision making (DDM) refers to when an individual collects evidence about two or more risky alternatives and decides when to stop and make a final choice. Real world examples include physicians running tests before diagnosing an illness, or commanders collecting intelligence before taking military action. We conducted a DDM study aimed at investigating how people know when to defer a ...

Models of Affective Decision Making

Intuitively, how you feel about potential outcomes will determine your decisions. Indeed, an implicit assumption in one of the most influential theories in psychology, prospect theory, is that feelings govern choice. Surprisingly, however, very little is known about the rules by which feelings are transformed into decisions. Here, we specified a computational model that used feelings to predict...

Computational models of decision making

This chapter presents a connectionist or artificial neural network approach to decision making. An essential idea of this approach is that decisions are based on the accumulation of the affective evaluations produced by each action until a threshold criterion is reached. This type of sequential sampling process forms the basis for decision making in a wide variety of other cognitive tasks such ...

Shared Mental Models & Decision-Making

The Problem: Decision-making among members of a group entails aggregating the opinions of the constituents. If the opinions are unconstrained, then concensus typically fails when any vote is taken. In contrast, when opinions reflect a shared model of the domain, then concensus is likely, assuming members can communicate accurately the reasons for their individual choices. How, then, will concen...
