Abstract
The purpose of this study was to measure the amount of error incurred by police officers when trying to accurately draw a previously completed movement path, which occurred during their response to a high-stress encounter. Secondary purposes of the study examined whether gridlines on a diagram or a distractor situation would influence memory accuracy. Officers (n = 23) were taken through a high-stress stimulus phase, followed by a memory recall phase where they were required to accurately draw their path of travel. Average distance traveled was 5.15 ± 1.98 m. Average discrepancy for all participants was an area of 3.23 ± 4.13 m2 and length of 1.43 ± 1.30 m. Significant length differences were found between actual and recalled paths of travel (p < .01). No other significant area or length differences were found.
