Abstract:

A model for measuring the cognitive effort required to execute a decision strategy is proposed. The model is based on a set of elmentary information processes EIPs, e.g., reads, comparisons, additions that are assumed to be common components of decision strategies. A weighted sum of EIPs model is shown to provide good predictions for response time and subjective reports of effort. Estimates of the time and effort associated with each EIP seem plausible and consistent with those found in other cognitive tasks. Overall, the EIP approach to conceptualizing and measuring the effort of executing a choice strategy receives strong support. Keywords Decision making, Decision theory.
