- Research on multiple cue judgment with continuous cues and a continuous criterion has been dominated by statistical modeling of the cue utilization with linear muliple regression. In this study we apply two cognitive process models to investigate the relative contributions of explicit abstraction of the cue-criterion relations and memory for concrete exemplars in a multiple-cue judgment task. The task was an extension of a previous tas with binary cues (P. Juslin, H. Olsson., A-C Olsson, 2003) and involved multiple continuous cues that either combined by addition or multiplication. As predicted by the process model (P.Juslin, L. Karlsson, & H. Olsson, manuscript) explicit abstraction of cue-criterion relations were induced in the additive task, while exemplar memory was induced in the multiplicative task.

- An experiment with a mulitple-cue judgment task tested the hypothesis that humans can only abstract explicit representations of cue-criterion relations when the cues are related to the criterion by an additive function. It is proposed that the sequential and capacity-constrained nature of controlled, explicit thought can only induce and execute linear additive cue integration; non-addititve environments require exemplar memory. The results showed that an additive task induced processes of cue abstraction and cue integration, while a multiplicative task induced exemplar processes. The results suggest flexible interplay between distinct representation-levels, a preference to abstract explicit "rules" whenever possible although this capacity is constrained to additive cue-criterion relations.
