Abstract:
Six separate experiments were conducted to investigate the effects of specific retrieval procedures on recall, recognition, confidence and the confidence / accuracy relationship for these retrieval domains. In experiment I the effects of retrieval procedures were considered as part of a recognised police interview technique, the Cognitive Interview (CI), while in experiments 11,111, and IV the retrieval procedures involved discrete context manipulations. Experiments V and VI focused exclusively on the confidence / accuracy relationship for recall as a function of specific retrieval procedures and question type. Results indicated that although frequently improving the quality and quantity of recall, the Cl and other types of context reinstatement manipulation did not reliably improve recognition accuracy from lineup presentations, nor did they have a significant moderating effect upon the confidence / accuracy relationship. However in experiment TV in which a long (three month) delay was utilised significant effects of context manipulation on recognition performance were found. With regard to confidence, experiment I indicated that the Cl was responsible for a significant increase in confidence of recall but not recognition. Results from experiments II, III, and iv indicated non consistent effects of context manipulation on confidence, rating-q for either recall and recognition. With regard to the confidence / accuracy relationship, results from the initial five experiments indicated that in very few instances was confidence and accuracy significantly related. However, in experiment VI confidence and accuracy was found to be reliably and consistently related The most important finding to emerge from this research suggests the retrieval procedure undergone by a witness (interactive interview / passive questionnaire), to be an important moderator of the confidence / accuracy relationship. As such the results are supportive of Leippe's (1980) two premises in which it is suggested that as reconstructional and social influences increase, the confidence / accuracy relationship will correspondingly decrease
