Abstract:
In air communication the identification of ambiguous message signals is substantially aided by operator familiarity with the message population and by the high degree of contextual redundancy present. Previous laboratory research on perceptual setting as an aid to the identification of ambiguous messages has ignored the factors of familiarity and contextual organization. The present experiment constituted an attempt to learn whether further response restriction in the form of setting cues would facilitate the recognition of visually distorted words drawn from a logically organized population, when subjects were familiar with the word categories and the specific words. Experimental variables were (1) degree of categorical restriction (in cuing) (2) type of familiarization (categories only or categories plus specific words), and (3) temporal position of the setting cues (before or after stimulus presentation). Principal findings were: (1) Increases in categorical restriction led to improved identification. (2) Familiarity with specific words, apart from a knowledge of the word categories, siginficantly improved identification. (3) Temporal position of cuing was not a significant factor. These results imply the probable helpfulness of setting cues for the identification of ambiguous messages in operational situations where familiarity and context have already markedly restricted the operator's responses.
