This paper reports on the results of two empirical studies which attempt to cast the source credibility variable in communication into a human information processing paradigm. The subjects for the studies were college students in an introductory communication course. The first study deals with the degree to which the processes of source credibility assessment and information seeking behavior can be considered to be structurally isomorphic. The second study seeks support for the proposition that more information is processed for and about perceived high credible persons than those with perceived lower credibility. Taking both cited studies into account, directions for additional research are offered. (Author/RB)
