"How has social psychology investigated the concept of change? In this chapter, we try to answer this question by moving in two directions. First, we briefly consider the main lines of research described in some of the reference books on social psychology, and the contributions of leading scholars who studied change (i.e. the great names in its history, cf. Lubek, 1993). Second, we analyze the abstracts of the papers published in two journals of pivotal importance in this field since their inception, i.e. the Journal of Personality and Social Psychology and the European Journal of Social Psychology. In line with recent developments in digital methods, the distant reading of large corpora of scientific literature can serve as a valid counterpart to more traditional ways of pursuing a historical quest like the one we posit here (Tuzzi, 2018)"--
