Background. The successful socialization and personal development of the individual are directly related to the processes of creating an adequate social picture of the world, which is promoted by attributive processes.

The Objective of the research was an empirical test of the religious impact on the choice of attribution in the representatives of the Muslims and Orthodox Christians. The tasks of identifying the peculiarities of attributive processes in Orthodox Christians and Muslims in solving problems with a different level of complexity in a group are discussed.

Progress Report. Two groups of Orthodox Christians and Muslims were invited to participate in the research. The main empirical part was preceded by the pilot research, whose aim was to obtain an array of possible options of attribution in the groups of Muslims and Orthodox Christians. Based on the results of the pilot research a questionnaire was created, it reflects the opinions of the group members and is supplemented by the author's versions.
After the approbation stage, the main stage of the research was carried out that is aimed at revealing the peculiarities of attributive processes in Orthodox Christians and Muslims in solving problems with a different level of complexity in a group discussion.

Research Results. The results showed that the representatives of the confessions under consideration are similar in using dispositional interpretations of the keys to success and reasons for failure, i.e. the internal attribution processes do not differ between Orthodox Christians and Muslims. In addition, differences in the attribution of both group success and failure, and also individual success and failure in the representatives of the two confessions in solving problems of varying degrees of complexity were revealed.

Conclusion. Religious macrofactor performed by traditional patterns of behaviour is less significant in comparison with the classical attributive processes being the results of group dynamic processes.
