The author distinguishes two kinds of cognitive processes: automatic p
rocesses, which are mostly subconscious, are learned and changed slowl
y and are not subject to the capacity limitations of working memory, a
nd strategic processes, which are conscious, are subject to capacity l
imitations, and can easily be adapted to situational circumstances. Th
e perception of advertising and the way it influences brand evaluation
involves both processes. Automatic processes govern the recognition o
f advertising stimuli, the relevance decision that determines further
higher-level processing, the retrieval of information, and the provisi
on of a heuristic for brand evaluation. Strategic processes govern lea
rning and inference formation. The relative importance of both types o
f processes depends on product involvement. The distinction of these t
wo types of processes leads to some conclusions that are at variance w
ith current notions about advertising effects. For example, the attent
ion span problem is relevant only for strategic processes. A certain a
mount of learning can occur with little conscious effort, and advertis
ing's effect on brand evaluation may be more stable for low- than for
high-involvement products.
