Top Down Processing of Human Body Odors

 Steven M. Platek and Gordon G. Gallup, Jr.
  
 

Abstract:
ABSTRACT The perception of human body odor by other humans is influenced by the "smellers" endocrinological state, make-up at the HLA-loci, and the intensity of the odor being presented. Similarly, when people smell other types of odorants their impressions can be influenced by the same factors, as well as the "smellers" preconceived bias about the other odors (e.g., is the odor thought to be harmful, etc.). We examined whether individual's rated an axillary odor differently depending on whether they thought that the odor was that of a male or a female and whether they thought that the odor came from someone who had engaged in sexual activity or not. Smellers preferred the odors that they thought were female and the odors that they thought were engaged in sexual activity.
