It refers to the fact that by accepting participation metaphor/language use/emergent grammar position, chaos/complexity theory does not reject psychological perspective. As it is stated , chaos complexity theory like socialists focus on the following issues: 1. all languages are static 2. there are mechanisms for language change 3.language and learning are seen as an open systems. Nevertheless, C/CT never rejects the following characteristics which psychological perspective focuses on: 1. languages are sensitive to initial conditions 2. there are systemic patterns with dynamic paths.
