(cog. psy) Eyewitness reliability
memories are not always accurate
bias
preconceived assumptions & stereotypes
episodic memory
schemas what you htink of the ppl around you, e.g sexism
witnessing a crime is a traumatic incident
how significant the event was to the witness
what was the focus of their attention
how the witness copes
e.g blocking out traumatic memories
motivated forgetting
memory is limited
the mind picks certain things to remember, therefore everything may not always be remembered
e.g people often focus/remember the weapon as they are concerned for their safety and that is the main threat
if the witness didn't perceive the event as a crime immediately, they most likely didn't recognise and store detailed memories from that time
age and health of the witness
elders do not have the same memory capacity as youths
biological factors
may have poor vision
issues with occipital lobe
difficulty processing and recognizing faces
issues with parietal lobe
may have poor hearing
temporal lobe
parietal lobe
frontal lobe
affect the perception, how something is remembered
can affect the suggestibility and therefore reliability of the witness
in a state of high terror, a witness' fight or flight kicks in which disables some unnecessary processing of senses
memories may fade or change over time
