Loftus-weapon focus
· Asked participants to come to a lab and wait in the
corridor. Participants heard a argument inside the lab.
Then in the 1st condition a man came out with greasy
hands and holding a pen. In the 2nd condition a man
came out holding a bloody knife.
· After participants were shown 50 photos and asked
to pick out the man who came out the room.
· Found that those participants in the 2nd condition
(who had high anxiety) had lower memory recall
performance
· This shows that high anxiety can lead to low memory
recall- supporting the inverted U theory…read more

Here's a taster:

Yuille and Cutshall- gunman gunned down
· Reviewed 21 statements from witnesses who saw a
man try and steal a gun from a gun shop, who was then
shot by the shop owner.
· Found that participants who were closer to the
witness at the time (high anxiety) had higher recall

· This shows that high anxiety levels doesn't cause low
memory performance- it actually causes higher
memory recall- opposes inverted U theory…read more
