| Abstract: | Multi-attribute decision problem analyses are dominated by accounts assuming that people select from a set of cognitive strategies in order to make decisions. This paper explores an alternative account based on sequential sampling and evidence accumulation. Two experiments varied aspects of a decision environment in order to explore competing models of decision behaviour. The results underline the intra-participant (here as: prcpt.) consistency but inter-prcpt. differences in the amount of evidence considered in decisions. This pattern was best captured by a sequential evidence accumulation model (SEQ). The SEQ model was also preferred by the minimum description length (MDL) criterion to a naive strategy-selection model (NSS). |
