Evolutionary-developmental modeling of neurodiversity and psychopathology.

Modeling the extremes of mental/emotional conditions requires explicit account of evolutionary-developmental sources of human neurodiversity, not merely psychopathology. The target article's approach could be improved by incorporation of a hierarchical scheme wherein mental/emotional infrastructure interacts across differentiated layers of function. The notion "symptom networks" thus calls for differentiation into hierarchically interacting components of mental/emotional evolution and development.
