We investigated effects of coffee cue presentation on desire for coffee and cognitive performance. The 2 (cue and no-cue)×2 (instruction: reward and no-reward) between-subjects design was used. The smell and sight of coffee were presented in the cue condition, but not in the no-cue condition. The participants in the reward condition were instructed that they would obtain coffee after the behavioral task and the amount of coffee depended on their performance of the task. The participants in the no-reward condition were instructed to perform as many tasks as possible. The dependent variable was performance of the behavioral task and subjective desire for coffee. In the task, the participants were asked to find vowels among letters printed on task sheets. As a result, the participants in the cue condition found more vowels than those in the no-cue condition, in both instruction conditions. There was no difference in subjective rating between any conditions. These results suggest that the coffee cue may enhance cognitive performance rather than desire for coffee.

Some studies have found that a neutral stimulus can become associated with caffeine or alcohol through classical conditioning. Further, several studies have shown that the taste, smell, and sight of caffeine or alcohol (e.g., decaffeinated coffee, non-alcoholic drinks) can acquire the properties of a conditioned stimulus. In human classical conditioning, a conditioning procedure (i.e., the pairing of a conditioned stimulus and unconditioned stimulus) and other factors (e.g., verbal information) are the sources of learning. In the present context, verbal information refers to whether participants are told that their drink is decaffeinated or non-alcoholic. The taste, smell, and sight of decaffeinated coffee (caffeine cue) or non-alcoholic beer (alcohol cue) can induce a conditioned response, even when participants know that the drink is decaffeinated or non-alcoholic. Therefore, in everyday life, decaffeinated coffee and non-alcoholic beer may change performance in coffee or alcohol drinkers.
