have ever met them  ● Many more  Hallucinations  - unreal perceptual experiences  ■ Auditory and tactile (hearing)  Formal thought disorder  - change topics with little coherent transition  ■ Loose associations or derailment  Disorganized or catatonic behavior  - unpredictable and apparently  untriggered agitation  ■ Catatonia - being unresponsive to the environment (adding  behavior of unresponsiveness)  Negative symptoms  - absence of behaviors, thoughts, or perceptions that  normally would be there  Restricted affect  - severe reduction/absence of emotional expression  Avolition  - Inability to initiate or persist at goal-directed activities (distinct  from depression because this only happens during active phase of illness)  ■ Cognitive deficits - basic cognitive processes are impaired or  slowed down
