False memory for analogical inferences: An indicator of text representational change but not of conceptual change

Se puso a prueba si la falsa memoria de inferencias analógicas implica un cambio conceptual acerca del análogo meta (AM), tal como sugieren, por ejemplo, Blanchette y Dunbar (2002), o sólo un cambio en la representación del texto meta. En el primer experimento un grupo que recibió un análogo base (AB) después de leer un análogo meta cometió falsos reconocimientos de inferencias analógicas en mayor medida que un grupo sin AB. No hubo sin embargo diferencias entre aquellos participantes que cometieron falsos reconocimientos y los que no en cuanto al grado de acuerdo con las inferencias. En el segundo experimento se obtuvieron los mismos resultados en un grupo en el que se controló que los participantes hubieran generado las inferencias esperadas. Se concluye que la falsa memoria de inferencias analógicas es un indicador de cambio en la representación del texto meta pero no de cambio conceptual con respecto al tema tratado por el texto meta.Two experiments investigated whether the false memory for analogical inferences implies a conceptual change of the target analog (TA), as suggested, for example, by Blanchette and Dunbar (2002), or only a representational change of the target text. In the first experiment a group of participants that received a source analog (SA) after having read a TA, produced more false recognitions of analogical inferences than a group without a SA. However, there was no difference between the participants who misrecognized analogical inferences and the ones who did not on the level of agreement with those inferences. In the second experiment the same results were obtained in a group where the generation of the expected inferences was controlled. These experiments show that the false memory for analogical inferences is an indicator of representational change of the target text but it is not an indicator of conceptual change of the target issue described by the target text

Analogies without commonalities? Evidence of re-representation via relational category activation

Analogies between cases with matching sets of connected relational structure is well-explained by existing theory. Re-representation is posited as an important mechanism to increase the flexibility of analogical processing by allowing the alignment of non-identical predicates across compared cases. It has been proposed that certain kind of categories can be characterized in terms of the relational structure that its exemplars tend to satisfy. Such relational categories have the property that all members of the category are analogous to one another. We ask whether a process of re-representation can alter the construal of a case and bring two evidently non-analogous cases into analogical alignment if they are both seen as members of the same relational category. We examine analogies between pairs of cases where the base is a canonical example of a relational category and the target would not be considered a member of the category on its own - critically, the cases themselves share no evident relational identities or similarities. In Experiment 1, we ask whether presenting a target case as part of an analogical pairing alters its construal. In Experiment 2, the pairs are presented for judgment as potential analogies. In both studies, participants interpret the target cases differently (consistent with the relational category) as a result of processing the analogy. There are two main implications: (1) a form of re-representation is at work in which the activation of a relational category triggers an alternate construal of the target case; and (2) this suggests a path to analogical status for cases that lack relational identities or similarities if the cases can both be fit to the same relational category.Fil: Oberholzer, Nicolás.

Overall Similarity Overrides Element Similarity when Evaluating the Quality of Analogies

Dominant computational models of analogical reasoning (e.g., SME, ACME and LISA) consider that two facts or situations are more analogous as the similarity between corresponding propositional elements increases. We report the results of two experiments demonstrating that when people judge the quality of an analogy, the similarity between matched elements is overridden by another type of similarity that implies comparing the meaning of whole propositions. In Experiment 1, participants received a base fact followed by two structurally identical target facts. Whereas in one of them propositional elements resembled their counterparts in the base, in the other they did not, but the meaning of the whole proposition resembled that of the base. Participants chose as more analogous the targets maintaining this second type of similarity. In Experiment 2, participants received a base cause followed by an effect, and were told that such effect reoccurred later as a consequence of an analogous cause. Participants had to decide which of two structurally identical facts was the cause of the target effect. Again, participants based their choices on global similarities, passing over similarities between propositional elements, but in a more ecologically valid task that involves comparing systems of relations. We conclude with some intuitions about the mechanisms underlying how people assess the quality on an analogy, and discuss their implications for future theories of analogical thinking.Fil: Minervino, Ricardo Adrian.
