Previous research dealing with the effects of source credibility on eyewitness' memories has found that sources that are seen as credible by the eyewitness' are more likely to be believed and more often change the witness' original memory than do sources seen as not credible. The present experiment is an extension of the previous research testing if adults that witness an event are affected differently by the misinformation presented by a child (non credible source) or an adult (credible source). Fifty-two people were shown a video depicting a scene of a husband and a wife arguing in their home. They were then given a narrative that contained some misinformation and some correct information about four critical details. Finally the subjects' memory for the original event seen was tested with a standard forced-choice recognition test. Accuracy and confidence levels were measured. The analyses revealed that witnesses were less accurate in the misinformation condition than in the correct condition, p=.048. However, source credibility did not affect witnesses accuracy differentially, p>.05.
