We examine the effort required to execute decision strategies and propose a set of
elementary information processes (EIPs)(eg, reads, additions, comparisons) as a common
language for describing these strategies. Based upon these component processes, a model
for measuring the effort required to execute a decision strategy is proposed which suggests
that effort is a weighted sum of EIPs. We test several variants of this model by attempting to
predict decision latencies and subjective reports of effort. The proposed weighted EIP model …
