Table 3 The nature of memory.

Declarative memory (“Knowing that”)
 Episodic Place and time dependant, eg, I found ten pence at the train station this morning
 Semantic Knowledge independent of time, eg, blue is a colour or that Paris is the capital of France
 Autobiographical Memories for events and issues relating to oneself. Can be semantic, eg, knowing you own a dog, or episodic, eg, remembering receiving the dog as a present
Non‐declarative memory (“Knowing how”)
 Procedural Skills such as knowing how to play the piano
 Priming Enhanced response to something because of recent exposure to it (eg, after buying a new car, suddenly noticing many similar ones on the road)
 Non‐associative A behavioural change brought by repeated presentation (eg, a loud crash that is initially startling and gradually becomes less so if it is repeated again and again)
 Classical conditioning A response originally elicited by one stimulus, can now be elicited by another one that originally had no effect (eg, Pavlov turning the light on before feeding the dogs resulted in the dogs salivating to the light alone)
