Exemplar-effects in rule-based multiple-cue judgment under time pressure

• The field of multiple-cue judgment focuses on the cognitive representations and processes involved in tasks where people need to integrate information across several cues into a judgment on a single criterion dimension. We present here an experimental approach to examine the influence of exemplar-based processes in human judgment, hypothesizing that a default exemplar-based process underlie judgment with emphasis on when cue-abstraction is discontinued. Using predictions from detailed cognitive models, we evaluate participants judgments on two tests with and without time pressure, after extensive learning with cue-abstraction. Results confirmed that participants were unable to use cue-abstraction under time pressure, but failed to confirm the expected shift to exemplar-based memory based on model fit on group level. Participants did however show typical behavioral markers for exemplar-based processes under time pressure, which emphasizes its likely contribution in the judgment process. Moreover, a large subsample of participants did show the expected shift to exemplar-based memory under time pressure. Nevertheless, the results provide novel insights to how exemplar-based processes influence cue-abstraction under time pressure, and open up for the idea of a default exemplar-based process in human judgment.
