  • Title: Discriminating the stimulus elements during human odor-taste learning: a successful analytic stance does not eliminate learning.
    Author: Stevenson RJ, Mahmut MK.
    Journal: J Exp Psychol Anim Behav Process; 2011 Oct; 37(4):477-82. PubMed ID: 22003966.
    Abstract:
    Odor "sweetness" may arise from experiencing odors and tastes together, resulting in a flavor memory that is later reaccessed by the odor. Forming a flavor memory may be impaired if the taste and odor elements are apparent during exposure, suggesting that configural processing may underpin learning. Using a new procedure, participants made actual flavor discriminations for one odor-taste pair (e.g., Taste A vs. Odor X-Taste A) and mock discriminations for another (e.g., Odor Y-Taste B vs. Odor Y-Taste B). Participants, who were successful at detecting the actual flavor discriminations, demonstrated equal amounts of learning for both odor-taste pairings. These results suggest that although a capacity to discriminate flavor into its elements may be necessary to support learning, whether participants experience a configural or elemental flavor representation may not.
