    "title": "Modeling an Experimental Study of Explanatory Coherence",
    "subtitle": null,
    "abstract": "The problem of evaluating explanatory hypotheses is to choose the hypothesis or theory that best accounts for, or explains, the given evidence. Thagard (e.g.. 1989) and Ranney (in press; Ranney & Thagard, 1988) describe a theory of explanatory coherence intended to account for a variety of explanatory evaluations; this theory has been implemented in a coimectionist computer model, ECHO. In this study, we examine three questions regarding the relationship between human explanatory reasoning and echo's explanatory evaluations: Does E C H O predict subjects' evaluations of interrelated propositions? Are local temporal order differences (not explicitly modeled by ECHO) important to the subjects? Does E C H O predict subjects' inflectional reasoning? W e found that subjects often entertain competing hypodieses as nonexclusive and presume an implied backing for certain (superordinate) hypotheses. These tendencies were modeled in E C H O by assigning a fraction of data priority (usually reserved for evidence) to the superordinate hypotheses. In simi, the E C HO model helps to interpret subjects' reasoning patterns, and shows continued potential for simulating explanatory coherence processes.",
