Renewal rate refers to how fast the reserves of attention
are replenished. It is assumed that a recovery
period will renew these resources. Thus, taking
a break to have a snack or eat lunch will rejuvenate
the resources of attention. Increasing cognitiveemotional
arousal (stimulating interest) also acts to
renew the reserves. Thus, entering a new museum
gallery on a new topic (especially one that is interesting)
generally results in increased attention to
exhibits.
