HealthDay (9/28, Preidt) reports, “People with psychopathic traits — such as callousness, manipulation, sensation-seeking and antisocial behaviors — are not able to use their sense of smell as well as other people can,” according to a study published online Sept. 18 in Chemosensory Perception. Investigators examined nearly 80 individuals to see whether or not their olfactory function was poor. Participants were also assessed for psychotic behavior and whether they possessed the ability to empathize with the feelings of others. The researchers “found that the people with the most psychopathic traits were more likely to have trouble identifying or distinguishing between smells.”
