Explanation of memory from the point of view of the information in our long-term memory, but we can't get it because we don't have the cues that enable us to access it
A cue is going to help us recall information, it has to be present at encoding (when the information goes into your head) and at retrieval (when we try to access the information)
Godden and Baddy studied sea divers who learned on land and recalled on land, learned underwater and recalled underwater, learned underwater and recalled on land, learned on land and recalled underwater - recall was higher when context matched
Evaluating the supporting evidence - the studies typically lack control for demand characteristics and other confounding factors, which weakens support for the theories
It is difficult to test the theories directly because we are making inferences about internal cognitive processes based on observable behaviour, so we cannot be certain that forgetting is due to lack of cues or state-dependent processes
