Abstract
SummaryIn two experiments and one follow‐up analysis, we examined the impact of using a repeated forced‐choice (RFC) line‐up procedure with child and adult eyewitnesses. The RFC procedure divides the identification task into a series of exhaustive binary comparisons that produces not only traditional line‐up information (identification decision and confidence) but also information about witness' selection behavior. Experiment 1 revealed that younger children (6‐ to 8‐year‐olds) struggled with the RFC procedure, while older children (9‐ to 11‐year‐olds) performed as well with the RFC procedure as with a simultaneous procedure (with wildcard). Experiment 2 replicated this comparable performance with adults. Witnesses' suspect selection behavior during the RFC was predictive of identification accuracy for older children and adults. A model examined the additional information provided by the RFC in experiments 1 and 2 and provided evidence that witnesses' patterns of responding can be used to estimate suspect selection bias (a proxy for suspect recognition strength) associated with individual line‐up decisions.
