Self-construal concerns how individuals understand who they are in relation to the broad set of cultural influences in which they live. We look at the nature and antecedents of self-construal, and characterize it as a self-process, rather than self-knowledge. Integrating work from the literature on social and evolutionary psychology, and philosophy, we suggest that the differences between independent and interdependent self-construal are best understood from a self-agency perspective. This concerns how people assess whether they are the causes of an action and, if so, whether their causal role depends on other people. We introduce and discuss the roles of three different modalities of agency involved in agency assessment: implicit (sensorimotor), intermediate (self-related affordances), and explicit (reflective) self-agency. We offer a conceptual model on how self-agency relates to power, evolutionary motivations and to social and cultural affordances, in the formation of, and interaction with, different types of dominant independent and interdependent self-construals.Keywords: self-construal, self-agency, power, social and cultural affordances, social environment, evolutionary psychologyIn 1991, Markus and Kitayama published an article that focused on a fundamental question of psychology-namely, the relationship between the individual self and the social and cultural setting. This became one of the most influential articles of the decade, referred to by Devine and Brodish (2003, p. 200) as a 'modern classic in social psychology'; it is the fourth (see Footnote 1) most cited Psychological Review paper in the web of science (Anderson, 2011). Self-construal theory's original framing-the first systematic social psychological attempt to map the relationship between culture and the self-remains powerfully insightful today.Self-construal theory introduced a new way to understand the individual consequences of cross-cultural differences, in terms of their implications for the construal of the self. Relating the debates on Eastern versus Western values to the individual level, Markus and Kitayama (...
