Anxiety

• Supporting evidence

  Johnson and Scott (1976)- found that between ppts hearing crashing and seeing a man run out with a pen and a man run out with a bloody knife, more ppts who saw the man with the pen were able to correctly identify the man.
• Limitation of Johnson and Scott’s evidence

  Ppts may have been surprised and not anxious.
• Contradictory evidence

  Pickrel (1998)- found that EWT was less accurate in unusual conditions.
• Supporting evidence

  Christianson and Hubinette (1993)- found that people who faced more anxiety (threatened by robbers) showed more accurate recall compared to those who witnessed the crime but were not threatened by the robbers.
• Limitation for Christianson and Hubinette

  There study occurred a few months after the crime meaning the other factors may have influenced their recall of the crime.
