Introduction to Memory Psychology
2
What do we already know about Memory? Short Term? Long Term? Memory loss? Anything else?

Memory
4
Memory is learning that has persisted over time It is our ability to store and retrieve information Cognitive Psychology

Discuss Imagine what would happen if you woke up to find you completely lost your memory. Answer these questions What do you normally do in a day that you would no longer be able to do? What would you be unable to do if you would not recognise your friends or family?
8
Discuss cont What experiences would you miss? How would you plan your day if you could not remember what you were just thinking about a few moments ago?
9
Key words Memory: the mental process involved in registering storing and retrieving information Capacity: the amount of information that can be stored Duration: the length of time that information can be kept
10
Key Words cont Short term memory: a limited capacity system for storing information for short periods Long term memory: an unlimited capacity system for storing information for long periods
11
Why can’t Clive Wearing remember? One possible explanation is that no new memory trace is laid down Can you think of two others? It could be laid down but disappears quickly Or it could be laid down but could not be retrieved : A functioning brain would be able to register info, store it and retrieve it

How did you do? Experiments like these demonstrate the limitations of short term memory According to George Miller the typical storage capacity for STM is 7 + - 2 items. Memory rehearsal strategies such as chunking can significantly increase memorisation and recall.
