Aim: Primary/recency effect on witness testimony? (and confidence)
Methodology:
# Lab exp, simulated courtroom procedure
# 192 Undergrad students (96M: 96F) Some heard witnesses give 'guilty' testimonies first, others heard 'innocnet' -Same material, different order
# Reach guilty or not guilty verdict and rate confidence
Results: Guilty witness first produced more guilty verdicts, also more confident in judgements suggesting strong primary effects in courtroom decision making
Evaluation: # Lab experiment used therfore has scientific credibility
# Lacks generalisability due to students being used
# Paid students therfore social desirability/demand charachteristics come into question
