Abstract
AbstractA total of 288 male and 288 female undergraduate students heard a taped voice of a mock abductor for a total of 18 seconds, 36 seconds, 120 seconds, or 6 minutes. One‐third of all subjects heard the voice for one massed trial, one‐third for two equal periods separated by a 5‐minute inter‐trial interval, and the remainder for three equal periods separated by 5‐minute intervals. Voice identification and confidence of response were tested immediately after observation, or 24 hours later, or 1 week later. Hit rates were significantly greater with longer voice‐sample durations, and were superior with two distributed exposures to the suspect's voice in contrast to one massed exposure or three distributed exposures. However, the false alarm rate in the suspect‐present line‐up differed significantly as a function of voice‐ sample durations and retention intervals, and voice‐sample durations and frequency of distributed exposures. False alarms in the suspect‐absent line‐up were consistently high (overall M = .58) and exceeded the overall hit rate (M = .40). Confidence of response was negatively correlated with suspect identification in the 18‐second voice‐sample condition, but was positively correlated with voice‐sample durations of 120 seconds and 6 minutes.
