The dissociation between the recall of stimulus frequencies and the judgment of contingency allows the placement of the competition effect in the final causal processing stages

ABSTRACT

In the predictive learning and causal reasoning literature it has beensuggested that the processing of events is under the control of a competitivemechanism. However, little is known about whether the competitivemechanism operates at the encoding or near the response stages. The presentwork suggests that measures based on the recall of frequencies of the cells inthe contingency table could help us in the placement of the competitionprinciple within the processing stages. As the contingency judgment about aconstant symptom-illness relation changed according to the validity of asecond different symptom, we concluded in favour of a competitionmechanism. However, estimated frequencies did not change as a result ofsuch manipulation. This dissociation suggests that the competitivemechanism operates near the response stage rather than at the stimulusencoding period
