The article examines the question of systematic character of time criteria (temporariness, temporality) in the practices of psychological interpretations. The approach for interpretation of self-identity dynamics is proposed. Self-identity is interpreted as a process of «symphonisation» of times (trans-temporality). Self-identity is analyzed as a problem of ensuring of stability of individual existence in the dynamics of self-development. The article presents in brief the results of studies conducted by the author in 1993–2009 which have been published in a number of publications including 3 monographs and 25 articles.
