In this study I focused on channel changing as an aspect of the select
ivity dimension of audience activity, and explored the influence of co
gnitive involvement (attention to and mental engagement with a televis
ion program) and perceived affective reactions (positive and negative)
on channel changing. Questionnaires were completed by 222 adult respo
ndents who owned remote control devices. Pearson and partial correlati
ons provided preliminary support for the study's hypotheses. LISREL an
alysis also revealed partial support. In general, the results point ou
t that channel changing while watching a television program is both a
reflection of lack of interest and an avoidance behavior. When viewers
are not mentally engaged with the program, and are experiencing negat
ive affective reactions to the content, channel changing increases. Th
e discussion links the study's findings to selective exposure research
and notes implications for media effects.
