the use of Semantic Differential scaling to define the multidimensional representation of odors
Journal of Sensory Studies, 2008Co-Authors: Pamela Dalton, Christopher Maute, Akiko Oshida, Satoshi Hikichi, Yu IzumiAbstract:ABSTRACT The mental representation elicited by smelling an odor often consists of multiple sensory and affective dimensions; however, the richness of this elaboration is difficult to capture using methods to rate the intensity of these factors in isolation. Attempts to use language descriptors for olfactory experience have also been shown to be rather limited; among nonspecialists, there is no universally accepted system for describing odors, leading to greater reliance on specific item associations. In this study, we explored the utility of Semantic Differential (SD) scaling for illustrating the various dimensions of olfactory experience. Three hundred volunteers rated 30 distinct odorants using 50 Semantic Differential scale adjectives. Three factors emerged from the analysis (based on 17 adjective pairs) accounting for 53% of the variance, and corresponding to the evaluation, potency and activity dimensions identified for other stimulus types. SD scaling appears to be a viable method for identifying the multiple dimensions of mental representation evoked when smelling an odorant, and may prove a useful tool for both consumer and basic research alike. PRACTICAL APPLICATIONS Although numerous methods of classifying odors have been developed, little agreement has been achieved on the dimensions that are useful to both basic and consumer research. The identification of a set of Semantic Differential adjectives that are relevant to olfactory experience can become a useful tool for classifying the qualitative and affective bases on which odorants differ. In particular, the degree to which odorants evoke multidimensional representations from other sensory modalities (visual, auditory, somatosensory or gustatory) can be usefully applied in the arena of product development both within and across cultures.

the middle of the road results from the aging Semantic Differential with four cohorts of medical students
Journal of the American Geriatrics Society, 2007Co-Authors: Thomas Stewart, Paul G Eleazer, Rebecca Boland, Darryl G WielandAbstract:OBJECTIVES: To explore the presence of negative stereotypical attitudes among medical students and the extent to which attitudes changed over time. DESIGN: Analysis of pre- and postexperience administration of attitude measures to four cohorts of medical students (two cohorts as quasi-controls and two cohorts as curriculum “treatment” groups). SETTING: The curriculum of a community-based medical school in the United States. PARTICIPANTS: Four sequential cohorts of medical students. INTERVENTION: Experience in a required comprehensive vertically integrated curriculum. MEASUREMENTS: The Aging Semantic Differential (ASD), using an 85-year-old woman as the cue image. RESULTS: The reliability scores for all administrations were acceptable. The two control cohorts demonstrated no change in attitude scores, whereas the treatment cohorts reflected a slight shift toward more-positive scores. However, all cohorts had scores for all sittings that were in the neutral range; on average students routinely scored 70% of the 32 items neither positively nor negatively. CONCLUSION: These students seemed not to hold negative stereotypes as measured using the ASD. Although two of the 32 items prompted negative stereotyping, and six items elicited positive stereotyping, attitudes were neutral about older adults. Characteristics of the ASD itself or of the response set used in this study may have affected the results.

the aging Semantic Differential a confirmatory factor analysis
Gerontologist, 1995Co-Authors: Robert C Intrieri, A Von Eye, Jeffrey A KellyAbstract:The Aging Semantic Differential (ASD), which is used to measure attitudes and quantify bias and negative stereotypes toward older people, is a 32-item scale published more than 20 years ago (Rosencranz & McNevin, 1969). Several factor analytic studies failed to replicate the original three-factor structure. Confirmatory factor analyses (CFA) using 100 third-year medical students compared six-factor models derived from the gerontological literature. A modified version of Holtzman, Beck, and Kerber's (1979) four-factor model proved to be the "best" comparative fit based upon a consensus of fit indices.
