P O S T E R S was to determine if a similar relationship between naming and memory would be observed with auditory stimuli. The auditory stimuli were computer-generated musical notes associated with a variety of musical instruments. Participants named the stimuli during the first phase of the test, and then, following a 10 minute retention interval, named the stimuli again and were asked whether they had experienced each stimulus during the initial phase of the test. During the second phase of testing, half the stimuli were from the first phase, and half were new. Some participants were provided with four possible names for each stimulus as they named them, while others were required to generate their own names. The results were remarkably similar to those found previously for odor and flavor stimuli, that is, consistent and correct naming was highly predictive of recognition memory performance. We conclude that similar processes are involved in naming and remembering of the olfactory and auditory stimuli, and we speculate that object identification processes played a critical role in the namingmemory relationship. #P105 POSTER SESSION III: OLFACTORY PERCEPTION, HUMAN PSYCHOPHYSICS & ANIMAL BEHAVIOR; PERIPHERAL TASTE DEVELOPMENT & SIGNALING The Effect of Odor Naming Feedback on Odor Naming And Recognition Memory Robert Frank, Erica Mannea Univ. of Cincinnati Cincinnati, OH, USA The current study examined the effect of corrective odor naming feedback on subsequent odor naming and recognition memory performance. It has been established that feedback can improve odor naming performance. The current study examined the relationship between odor naming and recognition memory with and without naming feedback to determine if the feedbackmediated improvement in naming was accompanied by an improvement in memory. Participants were separated into two groups; a feedback group and a control group. The performance of these two groups on an odor naming and odor recognition memory task was then compared. Results showed that odor naming and recognition memory performance improved as a result of corrective odor naming feedback. As expected, those who received feedback scored higher in naming and memory compared to those without feedback. More importantly, when corrective feedback was effective (changing incorrect naming to correct naming), memory performance approached 100%. When naming feedback was ineffective, no evidence for memory was observed. The results provide compelling evidence for a strong relationship between odor naming and recognition memory. We propose that when it was effective, the feedback allowed participants to access odor knowledge that was then used to support both odor naming and episodic odor memory. #P106 POSTER SESSION III: OLFACTORY PERCEPTION, HUMAN PSYCHOPHYSICS & ANIMAL BEHAVIOR; PERIPHERAL TASTE DEVELOPMENT & SIGNALING Smell and Prejudice: Affect influences on olfactory threshold Jhoette M Dumlao, Jhanvi Menon, Alan Hirsch, Oliaga Vrilos Smell &Taste Treatment and Research Foundation, LTD. Chicago, IL, USA Objectives of the study: To delineate the effect mood has on olfactory threshold. Methods : Five male and five female subjectively normosmic non-smokers, between ages 20 to 55,without known psychiatric disorders, odor sensitivities, or allergies, on no psychotropic medications, were recruited for this IRB approved study. Each subject was shown three randomly presented mood altering 10 minute audiovisual clips in a standardized method as per Chen and McClintock. After each tape the impact on mood was delineated by using the Ottawa- Georgia Mood Scale and olfactory thresholds were mapped as per the recommendations of the phenylethyl alcohol(PEA) smell threshold test of Doty. Results: All subjects underwent expected mood changes in response to the video segments. Average threshold in the positive, negative and neutral states were -5.4,-6.1 and -5.3 respectively with all values falling between-2 to -9. Of all participants, 30%, 20% and 60% showed greatest threshold in the positive, negative and neutral states respectively. Results were analyzed comparing positive affect vs. all conditions, negative affect vs. all conditions and both positive and negative affects vs. neutral conditions. The statistical significance was determined for all subjects, both sexes and orders of presentation, by using the paired T-test and Signed –Rank test for non parametric conditions. Analysis revealed no significant results (p
