Self-monitoring and identification of olfactory dimensions.

The basic categories of odors are not agreed on. Many classifications of odors have been proposed, but none has met widespread acceptance. The variability among qualitative judgments of odors which makes it difficult to construct reliable classifications may depend on cultural or personal idiosyncrasies. To check personality factors in odor evaluation, we asked 40 subjects, who had previously completed a personality questionnaire, to make qualitative judgments about 10 odors on 10 semantic differential scales. From comparison of two different self-monitoring groups, on the semantic differential, reliable differences did not emerge. While high self-monitoring subjects tended to maintain intermediate positions, for some odors, low self-monitors hazarded more polarized evaluations.

Interference processes in visual and olfactory stimulations.

The aim of this work was to verify whether two congruent inputs (simultaneous administration of one odor and the corresponding name) increase recall or, on the contrary, whether recall becomes worse when there is no coincidence between the two simultaneous stimuli (verbal and olfactory). The data show no significant difference among the experimental conditions. It seems then possible to conclude that a 'visual dominance' effect takes place vis-á-vis the olfactory mode.

Visual dominance in olfactory memory.

The object of the present study was to verify the emergence of a 'visual dominance' effect in memory tests involving different sensory modes (sight and smell), brought about the preattentive mechanisms which select the visual sensory mode regardless of the recall task.

Meaningfulness and isolation effect for normal and retarded subjects.

The aim of this study was to verify whether, in the normal and retarded subjects (aged 11.7 yr.), the isolation effect is less evidence the lower the meaningfulness of the material to be recalled. 12 groups were tested, six normal and six retarded, each of 25 subjects. The retardation was diagnosed with Raven's Progressive Matrix '38. Three series each of 9 CVC trigrams were used at 15--20%, 50--55% and 85--90% of associative value, respectively. Each trigram was exposed for 3 sec. As the level of meaningfulness increased so did the isolation effect for both normal and retarded subjects. For the retarded, however, the isolation effect only appears when the level of meaningfulness is very high.
