Theory Driven Processing and the Use of Complex Evidence.
Crocker, Jennifer; Taylor, Shelley E.
The influence of expectations and hypothesis testing on subjects' use of particular types of evidence to estimate covariations was investigated. Results of the first study indicated that all subjects relied most on positive confirming evidence and did not over-utilize evidence that was consistent with expectations. Results of the second study indicated that subjects reported seeing more instances which confirmed than disconfirmed their expectations, but subjects did not over-utilize the estimated frequency of expectation-consistent instances in their covariation judgments. Hypothesis-testing subjects relied most on the estimated frequency of hypothesis-confirming instances, while subjects who were not given a hypothesis to test did not appear to use any particular type of evidence to estimate covariation.
