Abstract

This paper investigates whether news story length and production pacing affect channel changing behavior in younger and older adults. Viewers used a remote-control device to choose among four local news programs that varied systematically by story length and pacing. In general, pacing and length have greater effects on younger viewers. Fast pacing increased viewers' evaluations of the newscasts, but when combined with long stories, decreased younger viewers' time spent on channel. Viewers' cognitive effort, physiological arousal, and recognition all decreased before and increased after a channel change. Frequent channel changing was associated with lower cognitive effort and recognition.
