What research did Milne and Bull do that supports the cognitive interview?
found the 'report everything' and 'context reinstatement' components of the cognitive interview to be the key techniques in gaining accurate, detailed recall, which suggests modified versions of the cognitive interview should concentrate on these features
give some research to contradict the cognitive interview?
Memon et al- report that officers think the 'change of perspective' component misleads witnesses into speculating about the event witness and therefore it is less frequently used
what can recalling the context in which the event happened include?
