This study investigates abstracted processes and introduces a new prototype abstraction model adapted to estimation tasks. This prototype abstraction model assumes that the processing of whole exemplar patterns supports the detection of the underlying statistics necessary for the abstraction of two extreme prototypes on the continuous criterion dimension of the task. The prototypes are stored in memory as valid reference points for future similarity-based judgments. This prototype model was

This study hypothesises that the training mode and the number of exemplars in training interact and affect subsequent model performance at test. The results from an experiment confirmed this hypothesis and showed that observational training supports an efficient prototype abstraction and feedback training supports an efficient cue abstraction. ARTICLE HISTORY From a neo-Brunswikian point of view emphasising adaptive learning, information about the criterion value would be for the observational learner something static and embedded in the environment. Thus, the external environment does not "feed back" the information contingent on the individual's actions as it does for the feedback learner. In that sense, observational training is a more unsupervised learning mode than feedback JOURNAL
