  The increasing integration of cognitive psychology with neuroscience provides evidence for the  mind-brain identity theory according to which mental processes are neural, representational, and computational.  Other philosophers dispute such identification on the grounds that minds are embodied in biological systems and extended into the world.  However, moderate claims about embodiment are consistent with the identity theory because brain representations operate in several modalities (e.g. visual and motor) that enable minds to deal with the world. Another materialist alternative to mind-brain identity comes from recognizing that explanations of mind employ molecular and social mechanisms as well as neural and representational ones.
