Does the type of judgement required modulate cue competition?

According to the comparator process hypothesis (Matute, Arcediano, & Miller , 1996), cue competition in the learning of between-events relationships ar ises if the judgement required involves a comparison between the probabilit y of the outcome given the target cue and the probability of the outcome gi ven the competing cue. Alternatively, other associative accounts (the Resco rla-Wagner model: Rescorla & Wagner, 1972) conceive cue competition as a le arning deficit affecting the target cue-outcome association. Consequently, the comparator process hypothesis predicts that cue competition occurs in i nference judgements but not in contiguity ones, for only the first type of judgement implicitly involves such a comparison. On the other hand, the Res corla-Wagner model predicts cue competition in both inference and contiguit y judgements, because it establishes no relevant role for the type of judge ment in producing cue competition. In Experiments: 1 and 2 we manipulated t he relative validity of cues and the type of question (inference vs. contig uity) in a predictive learning task. In both experiments cue found a cue co mpetition effect, but no interaction between the relative validity of cues and the type of question, suggesting that the Rescorla-Wagner theory suffic es to explain cue competition.
