ABSTRACT:
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)
