- - - - conducted exp using scissors, handgun, wallet, raw chicken as hand held items in a hair salon. Found recall accuracy poorer for the more unusual the item is. limits weapons effect
    - - interviewed pps months after, found they had no control over pps in the time apart. Effects of the anxiety may have been overwhelmed by other factors e.g. post event discussion- confounding variable to original study
  - - - points out that EWT are more important in real life, but pps answers in studies do not matter the same- EWT may be more adaptable than thought
    - - Showed pps two clips, 1) a mugger with dark brown hair 2) mugger with light brown hair. Pps discussed clips in pairs (having seen different versions). described a blend of the two 'medium brown'. EWT distorted through memory contamination
    - - Pps watched a video then asked misleading questions. Found recall was more accurate on central events than peripheral ones. Probably because focus was on central events so misleading questions had little effect
- - - - pps given a list of words organised into categories-pps given list 1 at a time not knowing there were categories. Recall was 70% for first list, but got worse as learnt more lists- proactive. then told the name of each category and asked to recall words- again 70% accuracy - interference is only temporary.
- - - - found witnesses reported greater detail when detectives had been trained in CI
    - - showed how some of the 4 elements of CI were more important, each technique did report more info than standard, but elements like report everything and context reinstatement had better recall
    - - CI needs special training and many forces cannot provide with their streachted resources to have enough hours
- - - - found that the type of rehearsal is more important than the amount. Elaborative rehearsal is needed for LT storage. This occurs when you link the information to your existing knowledge or understanding what the info means. This means it can be transferred to LTM without rehearsal
    - - K.F- STM poor for digits when recalled to him, but fine when he said them himself. Suggests there could be another Short term store for non verbal sounds
