Prior research has primarily focused on the usefulness of bias scales in voir dires (Kassin & Wrightsman, 1983; Jones et al., 2015), yet studies have additionally shown that jurors experience psychosocial stress (NCSC, 1998; Bornstein et al., 2005). The potential of using the Perceived Stress Scale (PSS; Cohen et al., 1983) as a screening tool was evaluated because stress influences a number of cognitive processes related to decision making (Soares et al., 2012; Morgado et al., 2015). Participants (n = 55) were asked to watch trial videos and read evidence summaries. Perceived stress was assessed at the beginning of the study. Jurors were asked to report a verdict and answer questions related to their comprehension. Highly-stressed jurors demonstrated significantly lower comprehension of the trial evidence than did lower stressed jurors, t(53) = 2.49, p = .02. Other significant relationships were found in relation to verdicts rendered, verdict consistency, and comprehension. Stress may impact different cognitive processes needed to render a competent verdict, though future studies will need a larger sample size to generalize these results.
