Comprehensive Study Notes on Personality and Psychological Disorders

Antisocial Personality Disorder (ASPD)

• Definition and Prevalence:     * Antisocial personality disorder is considered the most widely studied of all personality disorders.     * Statistically, it affects approximately $3\%$ of the male population.     * It affects less than $1\%$ of the female population.
• Core Characteristics:     * Individuals with ASPD do not experience worry or the need for a "cover-up" in most contexts; they do what they need to do to satisfy their own needs.     * They lack a frame of reference for feelings of fear, deprivation, or worry in others.     * There is a significant lack of empathy; an individual may state, "I do what I want, and I know you think I shouldn't feel bad, but that's on you… Because I don't act like [that]."
• Origins and Correlations:     * Many individuals with ASPD suffered from emotional deprivation in childhood, including abuse or neglect.     * Developmental Note: While there is a correlation between an abusive childhood and ASPD, it is not established as a direct causation.
• Spectrum and Societal Presentation:     * ASPD is a wide-spectrum disorder.     * Manipulation is common; the individual may blame the victim for being "stupid" for trusting them (e.g., signing over assets after knowing them for only two weeks).     * The "Front" (Double Lives): Relationships are often used as a front to appear socially acceptable.     * Serial killers and mass murderers have historically lived double lives, serving as husbands, fathers, soccer coaches, and teachers to avoid suspicion.
• Developmental Progression of Deviance:     * Behavioral issues typically start early in life.     * By adulthood, there is often a history of vandalism, petty theft, shoplifting, and assault.     * The speaker notes that extreme violence, such as dismembering bodies, does not happen immediately but is the result of deviance that starts early and escalates over time.

Dissociative Disorders

• General Features:     * These disorders involve significant memory loss and temporary (though potentially long-term) personality changes.     * They are rooted entirely in psychological causes rather than physical trauma.
• Dissociative Fugue Example:     * A person may walk back into their house after $20\,\text{years}$ and act as if they just came home from work on that same day $20\,\text{years}$ ago.     * They do not understand why their spouse looks older or why their children are grown and in college.     * During those $20\,\text{years}$, they lived a completely different life: they had a different name, a different job, and perhaps a different spouse and children.     * The shift is a "literal break," not a "double life," where one tries to juggle two households. It is not caused by hitting one's head or a car accident.

Dissociative Identity Disorder (DID)

• Nature of the Disorder:     * DID is extremely rare and involves a complete and utter shift between distinct personalities.     * It is distinct from choosing to act differently in various social situations (which is not DID).
• Clinical Presentation:     * The shift is coupled with memory loss of the previous personality's actions.     * Patients typically seek therapy for "losing time" rather than a belief that they have multiple personalities.     * Example: A person goes to work and the next thing they remember is waking up in Vegas $4\,\text{days}$ later with no knowledge of how they got there or what they did.     * Patients may also be approached by strangers on the street who call them by a name they do not recognize.
• Physiological Shifts:     * Personalities can exhibit different physical traits: some may require glasses to see while others do not.     * Some personalities may have specific allergies (e.g., an allergy to penicillin) that the host personality does not have.     * These physiological changes make the disorder much harder to fake than in the past.
• Role of Personalities:     * The internal personalities serve as a pattern of behavior designed to protect the "host."     * The sole job of these personalities is to ensure the host does not get hurt or overwhelmed by trauma.     * Personalities usually emerge in therapy when the therapist pushes into topics the personalities were created to guard.     * Personalities are often reluctant to "go back" once they have emerged.
• Treatment Goals:     * The goal in therapy is "integration," where all parts of the personality group work together, with the host personality in control.

Schizophrenia and Delusional States

• Paranoid Schizophrenia (Impairment):     * Involves delusions of persecution mixed with delusions of grandeur.     * The individual believes someone is after them because they are uniquely important (e.g., they have seen a secret government experiment).     * Their delusional systems are often complex and sophisticated, supported by facts, figures, statistics, and "proof."     * They are generally not a danger to society because they tend to isolate themselves in highly locked, "panic room style" homes to avoid others.
• General Schizophrenic Symptoms:     * Logic and Cognition: They do not follow standard rules of logic, reasoning, or intelligence. In their head, their language and world make perfect sense.     * Delusions: False beliefs, such as delusions of grandeur where the person believes they are inherently important without a specific cause.     * Perceptions: They suffer from hallucinations (e.g., seeing or hearing things others cannot). To the schizophrenic, these perceptions are very real and frustrating when others cannot share them.     * Emotional Dysregulation:         * Often emotionally inappropriate or immature.         * May giggle at inappropriate times or make disruptive noises.         * May engage in socially unacceptable behaviors, such as urinating in public.     * Behavior and Communication:         * Active but aimless; they lack goals or a clear direction.         * Communication may involve "word salads" or native-sounding jingles, making coherent conversation difficult; the speaker compares it to talking to a very young child.
• Genetics and Prevalence:     * In the general population, the chance of developing schizophrenia is a $1\%$ random occurrence.     * If a sibling has schizophrenia, the risk increases to $1\,\text{in}\,10$.     * If an identical DNA-matched twin has the disorder, the chance increases to $50\%$.
• Social Impact:     * Individuals with schizophrenia do not feel "sick" or abnormal; they believe what they are doing is right.     * They have extreme difficulty forming relationships and maintaining jobs.     * They are often found on the fringes of society or experiencing homelessness due to their inability to interact with others or follow social rules.

Other Psychological Categories

• Childhood Disorders:     * Includes ADD, ADHD, and autism.     * Because the biological causes haven't always been isolated, behavioral therapy is often used to manage these conditions where medication might not suffice.
• The "Kitchen Sink" (Unspecified Disorders):     * The DSM includes a section for unspecified disorders that do not fit into major categories like personality, addictive, childhood, sexual, or psychotic disorders.
• Specific Examples:     * Pyromaniacs: They do not hear voices telling them to start fires; they simply find it "fun" and do not want to stop.     * Histrionics: Addicted to drama. They treat everything as the "end of the world," similar to the "Chicken Little" story (screaming the sky is falling when hit by an acorn). They create drama even where no evidence for it exists; being around them is described as "exhausting."     * Passive-Aggressives: They may be internally enraged but will never admit it or express it directly. They will say they aren't angry while showing it through indirect behavior and withholding.

Questions & Discussion

• Question/Prompt (Implicit): Is there a connection between childhood abuse and ASPD?     * Response: Yes, there is a correlation, but it is not a causation.
• Legal Question: Can you avoid legal consequences for a crime by claiming a different personality did it?     * Response: No. Physiological proof (like allergies or eye-sight changes) makes DID much harder to fake in legal or clinical settings now.
• Course Logistics:     * Monday is the last formal class before finals.     * The upcoming lecture will focus on treatment protocols and options for the disorders discussed during the week.     * It is a good idea to know what treatment entails before seeking it.     * The instructor closed by wishing students a "very good evening."
