Abstract Subject headings

Individual voice and speech characteristics are important for earwitness identification. A target-absent line-up with six foils was used to analyse the influence of voice andspeech features on recognition. To create ecologically valid conditions for voice recognition,the present study used voices in conversation in the target event and for the foils.The participants were particularly successful in rejecting the two voice foils that weremost dissimilar to the target voice in articulation rate and pitch. These two foils werealso given somewhat higher confidence judgments than the other foils, although the levelof that confidence was still somewhat low. In fact, participants as a collective wereunderconfident for these two foils but were overconfident for the other foils. In addition,they showed somewhat better ability in their confidence judgments to distinguish correctand incorrect responses for the two most dissimilar foils than for the four foils for whichtheir identification responses were less successful. For the other four foils, which weremore similar to the target voice, the participants showed in their confidence judgmentsvery poor ability to distinguish between correct and incorrect identifications. Laterpositions in the parade were more often (erroneously) identified as the culprit, regardlessof the specific foils used in those positions.
