<p>This thesis aimed partly to examine the effects of gender on conversation dynamics, partly to investigate whether interaction between participants with contrasting opinions promotes cognitive development on a moral task. Another objective was to explore whether particular conversational features of interaction would have any impact upon a pair’s joint response or on each child’s moral development. The conversations were coded with regard to simultaneous speech acts, psychosocial behaviour and types of justifications used. The results show no gender differences regarding psychosocial processes, but the boys used more negative interruptions, more overlaps and significantly proportionately more justifications in the form of assertions than the girls in the study. Gender differences were often more pronounced in same-gender as opposed to mixed-gender pairs, but children also altered their behaviour to accommodate to the gender of their conversational partner. Children who participated in the interaction phase of the study showed more overall progress on an eight-weeks delayed post-test than those who did not. However the only conversational feature that was related to the outcomes of conversation and development was the use of expiatory force justifications which were associated with a more advanced reply immediately after interaction as well as two weeks later.</p>
