Aletha Huston and John Wright proposed
a somewhat different theory of attention
to television, positing that the features of
television that drive children’s attention may
change as a child ages. Specifically, they
claimed that in infancy, perceptually salient
features of television such as movement and
sound effects drive attention. With age and
experience, however, children are less influenced
by perceptual salience and are able to
pay greater attention to informative features
such as dialogue and narrative
