Schizophrenic pop - hearing voices or seeing people and things that aren't real. Makes you do crazy stuff sometimes.

Schizophrenic from my Psych101 lecture - a disorder that includes marked changes in behavior, mood, affect, and perception. Sufferers question reality, may feel persecuted, and experience sensory simulation that has no external cause. Genetic component coupled with trauma (stress-diathesis model), with an extremely high comorbidity of suicide attempts, depression, and self harm.

Antisocial pop - going against the grain, not wanting to hang out with people, being misanthropic. "Oh jeeze, i'm just so antisocial lately... maybe I'll party some other time, guys."

Antisocial personality disorder 101 - personlality disorder involving behavior that is typically not only interpersonally disruptive, but is often actively working against the benefit of others. Often accompanied by blunted capacity for empathy for others. Strong genetic component, may express after traumatic childhood experience or an abusive upbringing. Interestingly, has a high comorbidity for substance abuse and other potentially self-destructive behaviors. AKA sociopathy. Early.onset, typically pre-adolescence at latest for diagnosis. Otherwise, it's considered something akin to adolescent outburst, where it's expected to go away after some time. Early onset prognosis is worse.

Psychopathy pop - Cletus Cassidy, Michael Myers, Mrs. Voorhees, the Driller Killer, etc. See also "psycho"

Psychopathy 101 - similar to ASPD above, but not so much the self-destructive behaviors. Couples antisocial behaviors with complete lack of care or remorse for others, along with a superficial charm (refer back to Learning & Behavior, and social psych notes... charm is a skill!) to manipulate others into doing what they want. Often manifests as "conduct disorder" in kids, but diagnosis is difficult, as there is little objective criteria to go on. The very definition of Psychopathy is hard to nail down, given its broad symptom list, overlap with other diagnoses, and disagreement among professionals.

"Psycho" is often misused, as it actually refers to psychosis, which is a detachment from reality in which the sufferer can't tell what is and isn't real. Causes considerable distress and may lead to dangerous or self-injurious behaviors.
