We know that misinformation presented in interrogating questions or in advertising produces blendings, that even imagining a possible episode might produce blending as well, however, we do not know whether reasoning and problem solving can produce the same effect. On the other hand, models of analogy-making assume "perfect memory" for old episodes. The AMBR model of analogical problem solving has mechanisms for interaction between memory and reasoning which explain partial memory and memory distortions and has predicted blending effects which are due to the reasoning process. Such predictions have no parallel in any other model we know of. There has been no experimental support for these predictions so far. The current paper describes an experiment explicitly designed to test these predictions. It consists of three sessions: 1) solving three problems, 2) solving two more target problems by analogy with some of the problems in the first session, and 3) reproduction of the three problems in the first session. The results demonstrate that the degree of blending in the recalled stories depends on the target problem solved in the second session.

This paper presents an unusual prediction made by the DUAL-based model of judgment JUDGEMAP and its verification. The model is shortly presented as well as the simulation data obtained with it. These data predict that people will use the information on an irrelevant dimension when judging another dimension. This prediction is then tested in a psychological experiment and confirmed.

This paper presents a series of simulation experiments related to the interaction of memory and analogy-making in the AMBR model. This interaction makes it possible to demonstrate blending between superficially dissimilar episodes as a result of the established analogical mapping between them and of superficially and structurally dissimilar episodes as a result of a double analogy with a third episode. Both simulation experiments model the blending effect of analogy-making. The conditions for the emergence of such blending are explored on the basis of a proposed specific analogy-like retrieval mechanism.

This paper presents an attempt to build an integrated model of analogy-making and memory. In contrast to other models of analogy-making (Forbus et. al, 1995, Thagards et al,

This paper presents two experiments exploring context effects on human judgment and testing JUDGEMAP’s predictions that irrelevant information such as the color of the stimulus can produce a contrast effect with respect to skewed stimuli set to be judged. The first experiment demonstrates the effect on a perceptual judgment task (judging the length of lines which are colored in red and green), while the second experiment demonstrates exactly the same effect on a conceptual judgment task (judging the age of a person when the absolute age is presented by numbers with colored digits – red and green). These results rule out the “recalibration ” of the perceptual system explanation. The fact that the same effects were obtained in both cases prompts for a common explanation. JUDGEMAP provides such an explanation: the color is used in retrieving past instances in WM based on the spreading activation mechanism and thus the comparison set becomes biased. The biased comparison set which is then mapped on the scale elements produces a shift in the mean ratings.
