Odors and Opinions (05-17-21)

Research by Syrjanen and colleagues, linking responses to faces and odors smelled while evaluating them, can likely to applied in additional contexts.  The investigators found via a literature review that “Generally, the results indicate that facial expressions are classified more rapidly in the context of odors. Apart from a few studies that show face-odor valence congruency effects, the most consistent finding is that valenced odors affect perceived face valence overall (e.g., faces are perceived as more unpleasant in an unpleasant odor condition).”
