The role of predictive features in retrieving analogical cases

Abstract

Access to prior cases in memory is a central issue in analogical reasoning. Previous research accounts for access in terms of overall similarity between complete new exemplars compared to complete stored instances and stresses the relative importance of surface-level similarities in access to complete cases (Gentner & Landers, 1985; Rattermann & Gentner, 1987). However, for cross-domain remindings, abstract similarities capture the important commonalities between cases ( Schank, 1982; Seifert, McKoon, Abelson, & Ratcliff, 1986). Therefore, models of analogy must account for structural-level remindings when they do occur in terms of abstract similarities. In planning and problem-solving tasks, a stored exemplar may be more useful if accessed before the new pattern is complete, when past experience can bring to bear possible solutions or warn of potential dangers while the outcome is yet undetermined. Further, different partial sets of abstract features may result in differing access to analogous cases. Features that predict when prior cases might be useful to problem solving could serve as better retrieval cues than other abstract cues that are equally similar, yet less distinctive to the specific problem situation. To test these hypotheses, several experiments were conducted using thematic stories in a modification of the reminding paradigm developed by Gentner and Landers (1985). By examining the relative effectiveness of subsets of features in accessing relevant cases, it was found that a subset of abstract cue features predicting when a planning failure might occur led to more reliable access to complete prior analogies than did a subset of abstract features expressing specific information about planning decisions and outcomes. Further experiments show that how distinctly the feature sets characterize the conditions leading up to the planning decision point, and not differences in the overall similarity to the case, determines access based on abstract cues.
