Abstract

The experiment presented here was designed to explored the impacts of the semantic similarity and the test modality on listeners’ ability to identify speakers’ voice and recognition. Fifty-two undergraduate students participated in this study as subjects for course credit of General Psychology. Participants heard an audio tape of two people, a male and a female, uttering Chinese two-character words from six categories, and later decided who said each word. The author varied the semantic distinctiveness of the words that two people spoke and the distinctiveness of the test modality. Participants demonstrated higher source monitoring scores and the recognition advantage of source constancy between study and test when the same category words were spoken by the same speaker. The advantage of source constancy between study and test was not found in source monitoring. There was correlation between recognition and source monitoring only when the same category words were spoken by the same speaker and test modality was audition. These results suggested that if the words from the same source had more similar semantic features, subjects identified sources of the words more easily. The semantic similarity was an important factor that influenced the source monitoring.
