La autoeficacia es uno de los conceptos mas tratados ultimamente desde la psicologia social. A traves de el, se ha pretendido explicar ciertas creencias, pautas y comportamientos humanos segun factores afectivos, cognitivos y conductuales. El presente articulo plantea un acercamiento contemporaneo a este concepto, caracterizandolo y distinguiendolo de otros terminos de significancia parecida, y contrastando las diferentes definiciones que se le han otorgado. Tambien se enumeran sus campos de aplicacion investigativa y academica para finalizar con una propuesta especifica sobre la relacion de la autoeficacia con el termino posmodernista de competencias, especificamente con las llamadas competencias de agenciacion. Abstract Lately, self-efficiency is one of the most studied concepts in social psychology that thereby seeks to explain certain believes, standards and patterns of human behavior from an affective, cognitive and behavioral analysis level. This article proposes a contemporary approach to the concept of self-efficiency, characterizing it, distinguishing it from other terms with similar meaning, and contrasting the different definitions it has been attributed with. It also enumerates its research and academic application fields to conclude with the assumption of a relation between self-efficiency and the postmodern term competences or more specifically management competences
