A model of selection by aspects

Abstract A choice process model is discussed. This model retains the sequential nature of Tversky's Elimination by Aspect (EBA) heuristics: subjects are assumed to split the set of alternatives into increasingly smaller subsets until a one-element set is obtained. It differs from EBA in the way these splits are performed. We assume that: (i) the process cannot be reduced to elimination, (ii) subjects may process several attributes at the same time, (iii) at a given level of the selection/ elimination process, the alternatives may be examined relative to several attribute groupings. The results of an experiment supporting our model are presented.
