What can cause a flashbulb memory?
a release of hormones at the time of high emotion, or increased rehearsal of the memory

Cahill & McGaugh (1998)
hormones are released at times of high emotion- arousal helps the person respond to the situation- enhanced memory is an adaptive behaviour, helps person when in a similar situation again

Cahill and McGaugh (1995)
found that when rats are injected with adrenaline, their recall is better- however this is not generalisable to the human population

Neisser (1982)
after a shocking event memories are shared and therefore rehearsed, the more rehearsal the better the memory e.g. if you were injured you'd recall the event to several people

How accurate are flashbulb memories?
no real way of testing them- just because there is a lot of detail the memory does not mean that it is correct

Wright (1993)
asked people about the Hillsborough disaster 1989- found that five months after the event peoples memories became vague and had a lot of biases- suggests that flashbulb memories don't exist, same as normal ones which can be altered too

Mcloskey et al (1988)
similar experiment to Wright but used the space shuttle challenger explosion- found that some elements of the memory had been forgotten and there were also some errors in recall after 9 months
8 of 20
Conway et al (1994) on Mcloskey
said the the space shuttle was not a good example because it didn't have personal significance to the participants

Conway et al (1994)
used Thatcher's resignation on people in the UK- found that 11 months after the event 86% ppts still had a good recall and a flashbulb memory- proves that flashbulb memories do exist when the event is significant to you

What is Freud's theory of repression?
repress traumatic memories so that they are locked out of the conscious and stored in the unconscious- ego defence mechanism stops the individual from any excess worrying or anxiety

Williams (1994)
asked 206 women about their admittance to hospital following a sexual assault 20 yrs ago- found that 38% couldn't remember ever being treated and 16% said that they remembered now but didn't before
12 of 20
Karon & Widener (1997)
talked to WWII veterans who had repressed traumatic events- found that when they recalled the traumatic memories in therapy, all of the psychological issues the men had been suffering from disappeared
13 of 20
Loftus & Burns (1982)
lab experiment- both groups watched a video of a bank robbery- one group the violent version (little boy shot in face) CG= less violent- found that those in group 1 had poorer recall proving that more emotion causes impaired memory
14 of 20
Loftus and Pickrell (1995)
showed that it was possible to plant false memories in ppts about getting lost in the mall as a child
15 of 20
Antikainen et al (2001)
tested ppts who suffered with major depression who had impairments in their memory- after treating their depression he found that there was an improvement in their memory
16 of 20
What three reasons are there as to why there is a relationship between depression and memory?
depression makes people have low motivation and attention, so the memory might not have been encoded, shrinking of the hippocampus (in women) & negative recall bias- can only remember negative memories
17 of 20
What is mood dependant memory?
an individual can remember better when they're in the same state of mind e.g. when you're happy you remember positive things
18 of 20
What did Eich et al (1994) say?
asked ppts to read 16 words and they had to describe a sad or happy memory associated with that word- after 2 days they were asked to imagine being in a sad or happy mood and then recall the words, people asked to be in a sad mood remembered more sad
19 of 20
Evaluate Eich et al's study.
lab experiment- lacks ecological validity, only asked to imagine
