RT-based Concealed Information Test (CIT) has been suggested to detect lying with high accuracy. However, because previous research have been conducted with a minimum of five probes, limited evidence is available to determine whether or not the RT-based CIT is also useful in precisely detecting lies with less than five probes. In this study, the accuracy of an RT-based Concealed Information Test (CIT) was examined by varying the numbers of probes used for the test. Results suggested that the RT-based CIT produces accurate lie detecting outcomes as the number of probes increases from a single probe to three probes. When five probes were used, however, the accuracy level did not improve from the level achieved with three probes. Interestingly, the accuracy decreased when the stimuli for the RT-based CIT were constructed with numeric elements of an event such as the amount of money. Further discussed are possible explanations in regards to the differences observed in the RT-based CIT accuracy rates dependent on the numbers of probes.
