title: Detection of feigned memory impairments using a Chinese word task.
abstract: In this study the detection of feigned memory impairments was investigated using a forced-choice task with Chinese words as stimuli. Task difficulty on accuracy and response time and the faking strategies employed were examined for 85 participants, 42 men and 43 women, who were administered the experimental task. Following a simulation design, all participants performed under control and faking conditions. Their accuracy of performance and response times were measured. Analysis indicated significant differences on both outcome measures for the two conditions. Further, a significant difference in accuracy, but not in response time, among levels of task difficulty was observed. For classification accuracy, using the cut-off score criterion seemed more effective than using the below-chance criterion or response time. Implications for relying on chance criterion to identify deception are discussed.
