Eyewitness Testimony: The Effects of Discussion on Recall Accuracy and Agreement

While some previous research has suggested that group discussion may facilitate eyewitness accuracy, other research has drawn attention to the potential dangers of such discussion. The present studies examine this controversy and the interaction between accuracy and agreement following group discussion. It was found that individuals tend to agree in their testimony following group discussion, and are liable to change their original replies to bring themselves into agreement with group leaders' recall. A second experiment focused upon the actual items which witnesses agreed on following discussion. Changing the mode of questioning from interrogative to narrative eliminated differences in magnitude of agreement between discussion and no-discussion groups. As narrative recall leads to reporting of "easy" items, it was suggested that only certain "difficult" items are susceptible to discussion effects. The need for caution regarding the reliance on testimony following witness discussion was stressed.     

A skills training approach to the reduction of institutional offending

Offenses committed by those held in institutions can have repercussions at several levels: the individual must suffer the consequences of his or her actions; there may be a victim; and valuable staff time is spent adjudicating the outcome. A number of studies have suggested that an adjunct to behavioural training in institutions is a reduction in institutional misbehaviour—a suggestion which the present study sought to capitalize upon in a direct manner. In a borstal for young male law-breakers, referrals of individuals who received above average numbers of discipline reports in the institution were gathered. These people were then offered a place on a training course designed to attempt to modify behaviour towards authority figures, prison officers in particular. The course was carried out in two forms: a ‘Short’ Course of 4 days duration, and a ‘Long” Course spread over 8 weeks. Assessment of the effects of training was made by monitoring levels of discipline reports, and also by the administration of self-report and personality scales. Compared with No-training and Non-referred Controls, no significant changes in the frequency of receiving discipline reports was found following either mode of training. However, a number of changes on the self-report and personality measures suggested some degree of change after training. Implications for the construction of future courses with similar objectives are discussed.

A comparative outcome study of behavioral social-skills training, interpersonal-problem-solving and non-directive control treatments with child psychiatric outpatients

The purpose of the present study was to compare the short- and long-term efficacy of behavioral social-skills training and interpersonal-problem-solving with a control condition (non-directive treatment) with a clinical population of 61 socially-maladjusted outpatient boys. Treatment consisted of 12 weekly 1-hr sessions, with follow-up conducted at 12 months. A comprehensive assessment strategy was employed which included direct behavioral observations, parent, teacher, peer, self-report and academic performance measures. The results of this social-skills comparative outcome study indicated that the behavioral and interpersonal treatments resulted in changes on parent, teacher, self-report and peer sociometric ratings at post-treatment. At the 1-yr follow-up, the behavioral treatment maintained it's gains and continued to show modest improvement. Conversely, the interpersonal treatment manifested significant declines, as did the control group. These findings and implications for future research are discussed.
