A forensic psychologist used a set of digital facial images depicting varying degrees of distress to assess empathy levels in a group of 12 young offenders before and after they attended a 45-minute victim-awareness workshop.

Explain how two different sets of equivalent images could be used in this study and why this would be an improvement.
