Abstract: When inferring causal relationships, people are often faced with ambiguous evidence.Models of causal inference have taken different approaches to explain reasoning about such evidence.One approach -epitomized by Bayesian models of causal inference -defers judgment by representing uncertainty across multiple explanations.Another approachusually adopted by associative models -approximates uncertainty by positing within-compound associations, a special type of association that forms between simultaneously presented cues.Although these approaches explain many of the same experimental findings, we note some limitations of the latter approach.Within-compound associations form whenever two cues are presented simultaneously -even when the causal influences of the cues are already known.Since associative models use within-compound associations to modify beliefs about one potential cause when learning about another, associative models therefore predict that cues with known causal influences can have their influence revised as a result of being presented with other cues.In two experiments, we tested the predictions of the two approaches.The results were consistent with models that represent uncertainty across multiple explanations and inconsistent with models that use within-compound associations.
