Abstract [en]

Armelius, K., and Armelius, B-Å. Redundancy and inference behavior. Umeå Psychological Reports No. 102, 1976. -Within MCPL research redundancy has been treated as synonymous with intercorrelation among cues. As shown in the present paper this definition of redundancy is inadequate, and a definition of redundancy based on Brunswik' s conceptual frame-work and made in analogy with the definition of redundancy in information theory was proposed. Redundancy was defined as the difference between the sum of all squared correlations and the squared multiple correlation. That is, when the intercorrelation between cues does not contribute to the predictable variance in the criterion the task is redundant. When the cue intercorrelation does contribute to the predictable variance in the criterion the task was defined as a suppressor task. Some implications of this view of probabilistic inference tasks for research were discussed in the paper.
