Explain in simplest language so I can understand. Also make memory tricks and menmonics to remember
Here's everything from your 8 pages explained in the simplest way possible, with memory tricks throughout!
🧠 PSYCHIATRY - PSYCHOLOGY MADE SIMPLE
PART 1: LEARNING (Conditioning)
Classical Conditioning
Simple explanation: You learn to respond to something NEW because it was paired with something OLD.
Pavlov's dog: Bell (new) + Food (old) → Dog salivates to JUST the bell
Memory trick: "BELL before BALL" - the bell comes first, then the natural response follows automatically. It's INvoluntary (you can't control it, like salivating).
Operant Conditioning
Simple explanation: You do something because of what happens AFTER it (reward or punishment). It's VOLuntary - you choose to do it.
The 4-Box Grid (Skinner's quadrants):
| ADD a stimulus | REMOVE a stimulus | |
|---|---|---|
| Increase behavior | Positive Reinforcement ✅ | Negative Reinforcement ✅ |
| Decrease behavior | Positive Punishment ❌ | Negative Punishment ❌ |
Simple examples:
- Positive Reinforcement = Give candy for good grades → study more 🍭
- Negative Reinforcement = Remove seatbelt beeping when you buckle up → you buckle up more 🔔
- Positive Punishment = Get a speeding ticket → drive slower 🚔
- Negative Punishment = Take away phone for bad grades → behave better 📵
Memory trick: "Positive = ADD, Negative = REMOVE" (it's math, not good/bad!)
Extinction = Stop rewarding/punishing → behavior eventually disappears. Like ignoring a child's tantrum until they stop.
PART 2: TRANSFERENCE & COUNTERTRANSFERENCE
Simple explanation:
| Term | Who does it | Direction |
|---|---|---|
| Transference | PATIENT | Projects feelings onto DOCTOR |
| Countertransference | DOCTOR | Projects feelings onto PATIENT |
Memory trick: "Transference = The patient Transfers feelings to doctor. Counter = doctor Counters back."
Example: Patient treats doctor like their parent (transference). Doctor treats patient like their younger sibling (countertransference).
PART 3: EGO DEFENSES
Think of ego defenses as mental shields your brain uses automatically to protect you from painful feelings.
🔴 IMMATURE DEFENSES (unhealthy - like a child coping)
Mnemonic: "ADDFIIPP RRS" or just learn by story:
| Defense | Simple meaning | Memory trick |
|---|---|---|
| Acting Out | Deal with stress by DOING something impulsive instead of feeling it | "Act now, think never" - skip therapy, skip the pain |
| Denial | Pretend the bad thing isn't happening | "De-NILE" = like the river Nile, you're swimming in denial |
| Displacement | Take anger out on WRONG target | Angry at boss → yell at wife. "Kick the dog" syndrome |
| Dissociation | Brain goes completely numb/blank during trauma | "Dis-CONNECT" - brain disconnects from reality |
| Fixation | Stuck at a childish stage when stressed | "FIX-ated" = frozen in time like a broken clock |
| Idealization | See someone as PERFECT, ignoring all flaws | "Idol-ization" - making someone your idol |
| Identification | Copy someone you admire (unconsciously) | "I wanna BE like Mike" |
| Intellectualization | Use facts/logic to AVOID feeling emotions | Nerd defense: "Let me analyze my cancer statistics instead of crying" |
| Isolation of Affect | Talk about trauma WITHOUT any emotion | "Murder in the news voice" - describe horror flatly |
| Passive Aggression | Show anger indirectly (late to work, "forgetting") | "Passive-Aggressive employee" - never says mad, just shows it |
| Projection | Blame YOUR feelings on someone ELSE | "I'm not cheating, YOU are!" - the cheater accuses the partner |
| Rationalization | Make up excuses to justify your behavior | "I didn't want that job anyway" (sour grapes) |
| Reaction Formation | Feel one thing, act the OPPOSITE | Secretly hate child → smother them with love |
| Regression | Stress → go back to childlike behavior | Bedwetting after new sibling born. "Re-GRESS = go backwards" |
| Repression | Unconsciously FORGET traumatic memories | "Re-PRESS down" - pushed below consciousness, can't remember |
| Splitting | People are ALL good OR all bad, never in between | "Splitting" = split people into 2 groups. Classic in Borderline personality |
Big mnemonic for immature defenses:
"A Dumb Dog Forgot Five Important Individuals, Including Poor Rats Running Rampant" Acting out, Denial, Displacement, Fixation, Five (Idealization, Identification, Intellectualization), Isolation, Passive aggression, Rationalization, Reaction formation, Regression, Repression
🟢 MATURE DEFENSES (healthy - adults use these)
Mnemonic: "SASH" (Mature adults wear a SASH - the book even says this!)
| Letter | Defense | Simple meaning |
|---|---|---|
| S | Sublimation | Turn bad impulse into something SOCIALLY GOOD. Angry teen → plays sports |
| A | Altruism | Help others to feel better yourself. Mafia boss donates to charity |
| S | Suppression | CONSCIOUSLY choose to not think about it for now (vs repression = unconscious) |
| H | Humor | Joke about your own stress to cope. Med student jokes about boards |
Key difference - Suppression vs Repression:
Suppression = you CHOOSE to set it aside (conscious, temporary) Repression = it gets pushed down WITHOUT you knowing (unconscious)
PART 4: GRIEF
Simple: Normal sadness after loss. NOT a disorder. Adapts within 6 months.
Prolonged Grief Disorder = still intense, persistent, and impairing after 6-12 months = NOW it's a disorder.
Memory trick: "6 months to adapt, 12 months to diagnose a problem"
PART 5: CHILD DEVELOPMENT MILESTONES
The book uses a clever system - remember the first letters!
Infant (0-12 months)
Motor: "Parents Observe"
- P = Primitive reflexes (Moro, rooting, palmar, Babinski = "Mr. Peanut Butter")
- P = Posture milestones: lifts head (1mo), rolls/sits (6mo), crawls (8mo), stands (10mo), walks (12-18mo)
- P = Picks toys hand-to-hand (6-9mo), Pincer grasp (10mo)
- P = Points to objects (12mo)
Social: "Start"
- Social smile by 2 months
- Stranger anxiety by 6 months
- Separation anxiety by 9 months
Memory trick: "2, 6, 9 - Smile, Stranger, Separation" = 2-6-9 SSS
Verbal: "Observing"
- Orients to voice (4mo)
- Object permanence (9mo)
- "mama/dada" (10mo)
Toddler (12-36 months)
Motor: "Child"
- Cruises, first steps (12mo)
- Climbs stairs (18mo)
- Cubes stacked = age in years × 3
- Cutlery - feeds self (20mo)
- Kicks ball (24mo)
Social: "Rearing"
- Recreation = parallel play (24-36mo)
- Rapprochement = moves away AND comes back to parent (24mo)
- Realization = core gender identity (36mo)
Verbal: "Working"
- 50-200 words by 2yr
- 300+ words by 3yr
Preschool (3-5 years)
Motor: "Don't"
- Drive tricycle (3yr)
- Drawings (copies line/circle by 4yr)
- Dexterity - hops one foot (4yr)
Social: "Forget, they're still"
- Freedom from parent (3yr)
- Friends - cooperative play, imaginary friends (4yr)
Verbal: "Learning!"
- Language - 1000 words (3yr) = "3 zeros"
- Legends - tells detailed stories (4yr)
PART 6: CHILD ABUSE
Mnemonic: "N-P-S-E" = "No Parent Should Emotionally-Abuse"
| Type | Key Signs |
|---|---|
| Neglect (most common) | Poor hygiene, malnutrition, failure to thrive |
| Physical abuse | Injuries in DIFFERENT healing stages, shaken baby syndrome |
| Sexual abuse | STIs, UTIs, genital trauma. Peak age = 9-12 years |
| Emotional abuse | Labile mood, vague physical complaints with no cause |
Key fact for physical abuse: Injuries in DIFFERENT stages of healing = deliberate abuse (not one accident)
Vulnerable Child Syndrome: Parents think child is fragile and over-medicalize. "Kid wrapped in bubble wrap."
PART 7: CHILDHOOD PSYCHIATRIC DISORDERS
| Disorder | Memory Trick |
|---|---|
| ADHD | Onset before 12, diagnosed after 4. In ≥2 settings. Tx: methylphenidate |
| Autism | "ASD = Social Deficit + Repetitive" - more in males |
| Conduct Disorder | "Conduct = Children" (becomes Antisocial Personality in adults) |
| ODD | Argumentative toward authority for ≥6 months |
| Selective Mutism | Silent in SPECIFIC places (school), talks normally elsewhere |
| Separation Anxiety | Terrified to leave home/parent. Can fake illness to avoid school |
| Tourette's | Motor + vocal tics >1 year. Associated with OCD and ADHD |
| DMDD | Severe tantrums + ALWAYS angry between them. Onset <10, diagnosed >6 |
Conduct vs Antisocial: "Conduct = Children, Antisocial = Adults"
PART 8: MEMORY DISORDERS (Amnesias)
| Type | Simple meaning | Trick |
|---|---|---|
| Retrograde | Can't remember BEFORE the injury | "Retro = old stuff you forget" (retro = old) |
| Anterograde | Can't make NEW memories after injury | "Ante = can't go forward" |
| Korsakoff | Both types + confabulation (makes up stories to fill gaps) | Due to vitamin B1 (thiamine) deficiency in alcoholics |
Mnemonic: "Retro = Before, Ante = After" (alphabetically, B comes before A)
PART 9: DISSOCIATIVE DISORDERS
| Disorder | Simple meaning | Trick |
|---|---|---|
| Depersonalization/Derealization | Feel detached from your OWN body or surroundings. Know it's not real. | "Detached from me or my world" |
| Dissociative Amnesia | Can't remember personal info after trauma. May wander away (fugue) | "Fugue = flee from memory" |
| Dissociative Identity Disorder | Multiple personalities with different memories | Formerly "Multiple Personality Disorder". More in females. Associated with abuse |
Key: In depersonalization, reality testing is intact (you know something is off). In psychosis, you don't.
PART 10: DELIRIUM
Simple: Brain suddenly confused - fluctuates between alert and confused ("waxing and waning").
Features: Hallucinations (visual), confusion, sleep disturbance, agitation.
Causes mnemonic: "I WATCH"
Infection, Withdrawal, Acute metabolic, Trauma, CNS, Hypoxia (+ drugs, meds)
Key: Most common cause of altered mental status in hospital/ICU. REVERSIBLE.
Drugs that WORSEN delirium: Anticholinergics, benzodiazepines, opioids ("ABO = Always Bad in Old patients")
PART 11: PSYCHOSIS
Simple: Lost touch with reality - false beliefs (delusions), seeing/hearing things (hallucinations).
Types of hallucinations:
| Type | Cause hint |
|---|---|
| Auditory | Usually psychiatric (schizophrenia) |
| Visual | Usually neurologic (dementia) or drugs |
| Tactile | Alcohol withdrawal or cocaine ("cocaine crawlies") |
| Olfactory | Temporal lobe epilepsy |
| Hypnagogic | While GOING to sleep ("going = g for hypnaGOgic") |
| Hypnopompic | While WAKING up ("get pomPED up in the morning") |
Memory trick for hypnagogic vs hypnopompic:
"HypnaGOgic = GO to sleep" "HypnoPOMPic = POMP up awake"
PART 12: SCHIZOPHRENIA
Symptoms (3 types):
- Positive = ADDED experiences (hallucinations, delusions) - "too much"
- Negative = LOST abilities (flat affect, no motivation, no pleasure) = "4 A's: Affect flat, Alogia, Avolition, Anhedonia"
- Cognitive = Can't plan, focus, or remember
Diagnosis: ≥2 symptoms for ≥6 months (≥1 month active)
Treatment: Atypical antipsychotics (risperidone) - first line
Memory trick: "Positive = Plus (extra), Negative = Minus (missing)"
Schizophrenia Spectrum:
| Disorder | Duration |
|---|---|
| Brief Psychotic | 1 day - 1 month (usually stress-triggered) |
| Schizophreniform | 1-6 months |
| Schizophrenia | >6 months |
Memory trick: "1 day, 1 month, 6 months = Brief, Form, Full"
PART 13: MOOD DISORDERS
Mania features - "DIG FAST"
Distractibility Impulsivity/Indiscretion Grandiosity Flight of ideas Activity increased Sleep decreased Talkativeness
Bipolar Quick Guide:
| Type | What you need |
|---|---|
| Bipolar I | At least 1 full MANIC episode |
| Bipolar II | At least 1 HYPOMANIC + 1 depressive episode (never full mania) |
| Schizoaffective | Schizophrenia + mood episodes, but psychosis must occur ALONE for ≥2 weeks |
Memory trick:
"Bipolar I = I have MANIA (the big one)" "Bipolar II = II episodes needed: hypomania + depression"
