This document discusses using classical conditioning in music advertising. It describes classical conditioning as pairing an unconditioned stimulus that elicits a response with a conditioned stimulus that initially does not elicit a response. The document then summarizes an experiment where 244 students listened to music they either liked or disliked while viewing a slide presentation about pens, and were more likely to choose a pen color featured in the slides if they liked the accompanying music. The document concludes that pairing liked music with products can increase consumer preference and choice of that product through classical conditioning effects.
