Q

Tulving et al. (1983) - encoding specificity principle

Q

Godden and Baddeley (1975) - deep sea divers

A

divers were given lists of words to learn either on land or underwater, then asked to recall either on land or underwater (4 conditions). those who recalled in different contexts had 40% lower accurate recall than those who learned and recalled in the same context. suggests not having the same environmental cues both when learning and recalling effects memory and leads to retrieval failure.

Q

Carter and Cassaday (1998) - drug study

A

ppts had to learn words either on antihistamine drugs (internal physiological state from alert to drowsy) or on no drugs, and then recall either on or off antihistamine drugs. when internal state and recall were different, performance on memory tests was significantly worse. suggests when internal cues are absent, more forgetting occurs.

Q

+AO3 - research support, Aggleton and Waskett (1999)

A

museum of Jorvik in York, Viking era experience, constructed town as well as smell of Jorvik. ppts asked to recall details about details about trip to museum, significantly better recall when researcher recreated smell from museum. supports retrieval failure as it shows that using cues improves a persons ability to recall details of an event.

Q

+AO3 - RWA, cognitive interviews

A

one technique of the cognitive interview is reinstating context, which involves the witness possibly being taken back to the crime scene or to recreate it mentally. this aims to activate cues for the witness in order to retrieve memories from the crime. strength because research on retrieval failure has been very useful to the police force in order to improve EWT.

Q

-AO3 - recall & recognition

A

Godden and Baddeley replicated their deep sea diver study with recognition, asking ppts if they recognised words read to them from a list rather than recall. there was no context-dependent forgetting and performance was the same in all conditions. this is a weakness as it suggests retrieval failure is a limited explanation for forgetting as it only applies to recall, not recognition.
