Research to support the view that anxiety has a positive effect on recall from Christianson and Hubinette. They carried out a survey of 110 people who had witnessed 1 of 22 genuine bank robberies. Some had been bystanders, some had been directly threatened. The people who had been subject to the most anxiety showed more accurate recall, the recall remained after 15 months. This suggests that high levels of anxiety can increase accuracy of EWT.
