In this case, we focussed our purpose to make clear the effectiveness putting a partner's image into screen during their communication. And the communication was done under the context of Game theory especially so called prisoner's delemma game.The result is as follows :1) Under the conditions of special pay off matrix having possibilites of decreasing gain, and under the condition of having partner's image, cooperative alternatives were significantly chosen.2) The correlations between co-operative choice rate and competitive choice rate indiates that adding informations of partner's image increase the magnitude of information and bring low correlations.
