Abstract [en]

Annoyance and health symptoms associated with ambient odors are common problems, and current research emphasizes psychological/cognitive mechanisms as crucial when developing such problems. The objective of this study was to investigate if responses to odor exposure are influenced by beforehand given information. A total of 34 individuals were exposed to butanol, and were given either positive or negative information about the substance. Their responses were measured by repeated ratings of perceived odor intensity, perceived odor pleasantness/unpleasantness, self‐reported health symptoms and cognitive performance.

Individuals given negative information perceived the odor as more unpleasant and reported significantly more health symptoms than those given positive information. There were no significant differences between the groups on perceived intensity and cognitive performance. The results provide evidence that annoyance and health symptoms ascribed to odors to a high degree is influenced by cognitive factors, such as health risk perception.
