Also includes attitude toward the examiner (cooperative or uncooperative).
• Behavior: Examines stereotypy (repetitive speech/action without significance), mannerism (repetitive movements with significance), perseveration (repeating the same act despite stopping desire), echolalia (imitating words), echopraxia (imitating actions), negativism (resistance to movement), and catatonic symptoms (excitement, posturing, stupor, rigidity).
