Voice Identification: Levels-of-Processing and the Relationship between Prior Description Accuracy and Recognition Accuracy.
Walter, Todd J.
A study examined whether a person's ability to accurately identify a voice is influenced by factors similar to those proposed by the Supreme Court for eyewitness identification accuracy. In particular, the Supreme Court has suggested that a person's prior description accuracy of a suspect, degree of attention to a suspect, and confidence in identifying a suspect, are reliable predictors for accurately identifying a suspect. Subjects, 18 males and 42 females from an undergraduate psychology course or volunteers from the local community, listed to a voice and later described the voice on a speech characteristic checklist. Later they were asked to identify the voice from a lineup and denote how certain they were of their choice. Results indicated no relationship between voice description accuracy and identification accuracy, or between degree of confidence and identification accuracy. Moreover, depth of processing had no effect on description accuracy, identification accuracy, or the relationship between the two. Future "earwitness" research should: employ a voice lineup in which the target voice is either present or absent; use longer retention delay between target presentation and voice identification; and develop a valid descriptive measure. (Contains 21 references, 2 tables, and 1 figure of data. The voice description checklist is attached.) (RS)
