title: When discounting fails: An unexpected finding.
abstract: Two studies were designed to investigate the effects of prior information about plausible causes on subsequent attributions. In the Experiment 1, prior information was given about an internal and an external cause. It was predicted and found that the stronger an expectancy for a behavior, the more the behavior would be attributed to the cause that formed the basis of the expectancy. It was also predicted that (1) for facilitative causes, the stronger the expectancy based on a given cause, the less the behavior would be attributed to other causes (discounting), and (2)for inhibitory causes, the stronger the expectancy, the more the behavior would be attributed to other causes (augmenting). These predictions were not supported. It was suggested that discounting and augmenting did not occur because subjects had been given information about both causes which "locked in" their attributions to each cause. To test this explanation, a second study was undertaken in which observers were given information about only one cause. The results of Experiment 2 indicated that discounting and augmenting may only occur for attributions to causes about which no prior information is available.
