Fraud Detection Post Training |
Percent confidence that a given vignette describing fraud is actually an example of fraud, measured at baseline and immediately after 4 weeks of training. Participants were given a vignette describing fraud (which was mixed in with vignettes not describing fraud) and were asked to give their percent confidence that this is actually an example of fraud. Higher confidence indicates higher accuracy when detecting fraud, with a minimum of 0 and a maximum of 100. Measures accuracy in discriminating fraud from non-fraud text-based scenarios (using 3 parallel forms). |

Driving Simulator Hazard Perception Post Training |
Driving simulator (scenarios including hazards) measures of speed, maximum brake compression, and lane position, at baseline and immediately after 4 weeks of training. These measures provide an estimate of accuracy in driving scenarios that involve hazards in the DriveSafety simulator (using 3 parallel forms). All measures were transformed into Z scores and averaged in order to create a measure of overall driving performance, where higher scores represent more dangerous (worse) driving performance. |
