Selective Exposure

Abstract

This article provides an overview of selective exposure research, with an emphasis on the relationship between selective exposure and the evolving media environment. First, a brief history of selective exposure studies in social psychology and political communication is presented within the context of contemporaneous social and technological changes. Next, the consequences and democratic implications of selective exposure are discussed. In addition, arguments about the scale of partisan selective exposure, absence of selective avoidance, and normatively positive aspects of selective exposure are reviewed.

Modeling and Simulation of Opinion Natural Reversal Dynamics with Opinion Leader Based on HK Bounded Confidence Model

“…e bounded confidence rules indicate that a pair of agents begin to impact each other when the difference between their opinions is not higher than a given threshold [18], and the evolution of collective opinions may eventually lead to three stable states: consensus, polarization, or separation [19]. Both the DW model and the HK model are repeatedly updated with the average value of opinion based on bounded confidence at discrete time points, and this rule conforms to the "selective contact" in social psychology [20]. However, their differences lie in the range and mode of individual communication, and at a specific time, only a pair of agents which meet the confidence threshold will randomly interact in the DW model, while all individuals who satisfied this condition can communicate their views at the same time in the HK model, and the state of each agent's opinion is always updated to the average value of all individuals within their confidence threshold.…”
