A research agenda set forth in the 1975 book Political Communication is wel
l suited for study in an era when conventional mass communication gives way
to less centralized channels. Features of this approach include a focus on
behavior and cognitions rather than inferred attitudes, close attention to
measurement of media experience, conceptualization of curvilinear processe
s that occur otter rime, comparative theorizing that can be tested across d
ifferent national systems, and reconceptualization of communication as a pr
ocess defined more by its functions than whether it occurs via mass media o
r interpersonal channels.
