Chung, S., Fink, E. L., Waks, L., Meffert, M. F., & Xie, X. (2012). Sequential
information integration and belief trajectories: An experimental study using
candidate evaluations. Communication Monographs, 79, 160-180.
?? : Using an extended model of information integration theory, the
sequential information integration model (SIIM), the effects of initially presented
information on belief trajectories were investigated. SIIM predicts (a) damped
oscillatory trajectories when congruent information and incongruent information
are presented alternately; and (b) smaller amplitudes of trajectories when initial
beliefs have greater weight. An experiment was conducted that utilized a hypothetical
election (N=201). Participants initially received specific (vs. no) information
about candidates’ positions on issues and then indicated their evaluation of
the candidates 11 times in response to additional pieces of information that
were provided over time. As predicted, belief trajectories were found to have
damped oscillatory patterns. The amplitude of the trajectories was smaller for
participants with strong party identification than for those with weak party
identification. Implications of these findings for theories of persuasion and
political decision-making are discussed.
