was to determine if a similar relationship between naming and<br />
memory would be observed with auditory stimuli. The auditory<br />
stimuli were computer-generated musical notes associated with a<br />
variety of musical instruments. Participants named the stimuli<br />
during the first phase of the test, and then, following a 10 minute<br />
retention interval, named the stimuli again and were asked<br />
whether they had experienced each stimulus during the initial<br />
phase of the test. During the second phase of testing, half the<br />
stimuli were from the first phase, and half were new. Some<br />
participants were provided with four possible names <strong>for</strong> each<br />
stimulus as they named them, while others were required to<br />
generate their own names. The results were remarkably similar to<br />
those found previously <strong>for</strong> odor and flavor stimuli, that is,<br />
consistent and correct naming was highly predictive of<br />
recognition memory per<strong>for</strong>mance. We conclude that similar<br />
processes are involved in naming and remembering of the<br />
olfactory and auditory stimuli, and we speculate that object<br />
identification processes played a critical role in the namingmemory<br />
relationship.<br />

The Effect of Odor Naming Feedback on Odor Naming<br />
And Recognition Memory<br />

The current study examined the effect of corrective odor naming<br />
feedback on subsequent odor naming and recognition memory<br />
per<strong>for</strong>mance. It has been established that feedback can improve<br />
odor naming per<strong>for</strong>mance. The current study examined the<br />
relationship between odor naming and recognition memory with<br />
and without naming feedback to determine if the feedbackmediated<br />
improvement in naming was accompanied by an<br />
improvement in memory. Participants were separated into two<br />
groups; a feedback group and a control group. The per<strong>for</strong>mance<br />
of these two groups on an odor naming and odor recognition<br />
memory task was then compared. Results showed that odor<br />
naming and recognition memory per<strong>for</strong>mance improved as a<br />
result of corrective odor naming feedback. As expected, those<br />
who received feedback scored higher in naming and memory<br />
compared to those without feedback. More importantly, when<br />
corrective feedback was effective (changing incorrect naming to<br />
correct naming), memory per<strong>for</strong>mance approached 100%. When<br />
naming feedback was ineffective, no evidence <strong>for</strong> memory was<br />
observed. The results provide compelling evidence <strong>for</strong> a strong<br />
relationship between odor naming and recognition memory. We<br />
propose that when it was effective, the feedback allowed<br />
participants to access odor knowledge that was then used to<br />
support both odor naming and episodic odor memory.<br />

Objectives of the study: To delineate the effect mood has on<br />
olfactory threshold. Methods : Five male and five female<br />
subjectively normosmic non-smokers, between ages 20 to<br />
55,without known psychiatric disorders, odor sensitivities, or<br />
allergies, on no psychotropic medications, were recruited <strong>for</strong> this<br />
IRB approved study. Each subject was shown three randomly<br />
presented mood altering 10 minute audiovisual clips in a<br />
standardized method as per Chen and McClintock. After each<br />
tape the impact on mood was delineated by using the Ottawa-<br />
Georgia Mood Scale and olfactory thresholds were mapped as per<br />
the recommendations of the phenylethyl alcohol(PEA) smell<br />
threshold test of Doty. Results: All subjects underwent expected<br />
mood changes in response to the video segments. Average<br />
threshold in the positive, negative and neutral states were -5.4,-6.1<br />
and -5.3 respectively with all values falling between-2 to -9. Of all<br />
participants, 30%, 20% and 60% showed greatest threshold in the<br />
positive, negative and neutral states respectively. Results were<br />
analyzed comparing positive affect vs. all conditions, negative<br />
affect vs. all conditions and both positive and negative affects vs.<br />
neutral conditions. The statistical significance was determined <strong>for</strong><br />
all subjects, both sexes and orders of presentation, by using the<br />
paired T-test and Signed –Rank test <strong>for</strong> non parametric<br />
conditions. Analysis revealed no significant results (p
