В статье рассматриваются теоретические и экспериментальные подходы к моделированию социальных взаимодействий. Общение и обмен информацией с другими людьми влияют на поведение человека в разных сферах жизни. В основном такое влияние оказывают лидеры, выдающиеся индивиды , обладающие высоким социальным статусом или экспертными знаниями. Социальные взаимодействия исследуются в моделях социального обучения, теоретико-игровых моделях, моделях конформности и др. Не хватает формальных моделей асимметричных взаимодействий, с помощью которых можно выделить объективные характеристики, отражающие высокий социальный статус индивида и его восприятие другими, а также показать влияние лидера на других людей и проанализировать механизм этого влияния.

his article explores theoretical and experimental approach to modeling social interactions. Communication and exchange of information with other people affect individual’s behavior in numerous areas. Generally, such influence is exerted by leaders, outstanding individuals who have a higher social status or expert knowledge. Social interactions are analyzed in the models of social learning, game theoretic models, conformity models, etc. However, there is a lack of formal models of asymmetric interactions. Such models could help elicit certain qualities characterizing higher social status and perception of status by other individuals, find the presence of leader influence and analyze its mechanism.
