Towards Comprehensiveness in Theory Construction in Second Language Acquisition: A Critical Look

Sparse unequivocal evidence among Second Language Acquisition (SLA) scholars boosts incomprehensiveness in theory construction. Individualism in theory construction is at the expense of excluding other perspectives and adopting a particular ideology from a parent discipline without referring to other perspectives. The purpose of the present paper is to achieve comprehensiveness in theory construction through a biological look. In a sense, the current work, although valuing the nurture-based attempts in SLA, holds that the orientation towards nature-based ideology will boost compatibility among a variety of points of view. Besides, to achieve comprehensiveness in research findings, attempts should be made to provide a link between hard and soft sciences
