While some research suggests that olfactory imagery exists
and operates in ways similar to that of actual scents,
research also suggests that olfactory processing differs in
important ways from that of the other senses, especially that
of vision. It has been shown, for example, that although
individuals can discriminate among thousands of different
odors (Buck and Axel 1991) and are reasonably good at
detecting odors they have smelled before (Gottfried 2010),
they are quite poor at identifying odors they smell (Cain
1979). That is, individuals often have difficulty stating just
what it is they happen to be smelling at any particular moment,
unless they can see the odor referent. Thus, while
most healthy individuals have little difficulty identifying or
naming objects that they see, they have considerable difficulty
naming objects that they smell—if they cannot see the
object that is emitting the odor (Gottfried and Dolan 2003).
