Guess You're Right on This One Too: Central and Peripheral Processing in Attitude Changes in Large Populations

In processes of attitude change people may employ different mechanisms, for example focussing on arguments (central processing) versus focusing on the reputation of the source (peripheral processing). In this paper we formalise these processes and systematically explore how this affects the relation between two attitude dimensions. Both an aggregated correlation as a local heterogeneity index are used to explain the effects. Results indicate that peripheral processing contributes to the relation between attitudes, but only on a local level.
