Complete Answers (All 12 Questions)

Q1. Describe perceptual processes and factors influencing perception.

Perception - Definition

Perception is the process by which organisms interpret and organize sensation to produce a meaningful experience of the world. It is an active cognitive process that goes beyond mere sensory input.

Perceptual Process (Steps)

1. Sensation/Reception Sensory organs receive raw stimuli from the environment (light, sound, touch, taste, smell).

2. Selection Not all stimuli are attended to. The brain selects relevant stimuli based on interest, need, and novelty. This is called selective attention.

3. Organization The selected sensory data is organized into a meaningful whole. Gestalt principles govern this:

Figure-Ground: Distinguishing an object (figure) from its background.
Proximity: Objects close together are seen as a group.
Similarity: Similar objects are grouped together.
Closure: Incomplete figures are perceived as complete.
Continuity: We perceive continuous patterns.

4. Interpretation The organized pattern is given meaning based on past experience, memory, and context.

5. Response/Reaction The individual responds behaviorally or cognitively based on their interpretation.

Factors Influencing Perception

A. External (Stimulus) Factors

Intensity: Brighter lights, louder sounds attract more attention.
Size: Larger objects are noticed more easily.
Contrast: Objects that differ from their surroundings stand out.
Movement: Moving stimuli attract more attention.
Novelty: New or unusual stimuli are more perceptible.
Repetition: Repeated stimuli are more easily noticed.

B. Internal (Personal) Factors

Needs & Motives: Hungry people notice food more readily (e.g., a thirsty person perceives mirage as water).
Interest & Attention: We perceive what we are interested in.
Past Experience: Prior learning shapes how we interpret stimuli.
Mental Set: Readiness to perceive in a certain way - "set" determines what we see.
Emotions: Emotional state colors perception (depressed people see things negatively).
Personality: Introverts and extroverts perceive social situations differently.
Culture: Cultural background affects perception of colors, space, and social situations.

C. Physiological Factors

Sensory acuity (sharpness of sense organs)
Age-related changes in perception
Fatigue and physical state

Q2. Describe the scope and branches of Psychology in detail.

Definition of Psychology

Psychology is the scientific study of behavior and mental processes. The word is derived from Greek: "Psyche" (soul/mind) + "Logos" (study).

Scope of Psychology

Psychology has a very wide scope:

Individual behavior - studying how individuals think, feel, and act.
Group behavior - how people behave in social settings.
Normal and abnormal behavior - understanding mental health and mental disorders.
Applied areas - education, industry, health, law, sports.
Cross-cultural and universal human experiences.

Major Branches of Psychology

Branch	Focus
General Psychology	Basic principles of behavior and mental processes
Abnormal Psychology	Study of psychological disorders and deviant behavior
Social Psychology	How people influence and relate to each other
Developmental Psychology	Human growth across the lifespan
Clinical Psychology	Diagnosis and treatment of mental disorders
Health Psychology	Psychological factors in physical health and illness
Educational Psychology	Learning, teaching, and educational settings
Industrial/Organizational Psychology	Behavior in the workplace
Neuropsychology	Brain-behavior relationships
Forensic Psychology	Psychology in legal and criminal contexts
Sports Psychology	Mental factors in athletic performance
Counseling Psychology	Helping people cope with life challenges
Physiotherapy-relevant	Rehabilitation psychology, pain psychology, patient compliance

Importance of Psychology in Physiotherapy (BPT)

Understanding patient motivation and compliance.
Managing chronic pain (biopsychosocial model).
Handling anxiety and depression in disabled patients.
Communication and therapeutic relationship skills.

Q3. Describe classical conditioning with its principles and applications.

Definition

Classical conditioning (Pavlovian conditioning) is a form of learning in which a neutral stimulus, when repeatedly paired with an unconditioned stimulus, eventually comes to elicit a response similar to the one originally elicited by the unconditioned stimulus.

Discovered by: Ivan Pavlov (Russian physiologist, Nobel Prize 1904) through his famous experiment on dogs.

Pavlov's Experiment

Term	Example
Unconditioned Stimulus (UCS)	Food (naturally produces salivation)
Unconditioned Response (UCR)	Salivation to food (natural reflex)
Conditioned Stimulus (CS)	Bell (neutral initially)
Conditioned Response (CR)	Salivation to bell (after training)

Procedure: Bell was rung just before food was given, repeatedly. Eventually, the dog salivated at the sound of the bell alone.

Principles of Classical Conditioning

Acquisition: The gradual development of the conditioned response when CS is paired repeatedly with UCS.
Extinction: When CS is presented repeatedly without UCS, the CR gradually weakens and disappears.
Spontaneous Recovery: After extinction, if rest is given and CS is presented again, the CR reappears (though weaker).
Stimulus Generalization: The CR is elicited not only by the original CS but also by similar stimuli (e.g., dog salivates to similar-pitched bells).
Stimulus Discrimination: The organism learns to respond only to the specific CS and not to similar stimuli after differential training.
Higher-Order Conditioning: A well-established CS can itself act as a UCS to condition a new neutral stimulus.

Applications of Classical Conditioning

1. Systematic Desensitization (Behavior Therapy)

Used for phobias and anxiety.
Patient is progressively exposed to fear-inducing stimuli while relaxed.
The fear response (CR) is extinguished.

2. Aversion Therapy

Used in alcohol/drug addiction.
A nauseating drug (UCS) is paired with alcohol (CS) → patient feels sick at the thought of drinking.

3. Advertising

Pleasant stimuli (attractive people, music) are paired with a product to create a positive attitude.

4. Phobia Development

Watson's "Little Albert" experiment showed how fear (phobia) can be classically conditioned.

5. In Physiotherapy

Patients can develop conditioned anxiety responses to treatment (needle phobia, white coat syndrome).
Understanding this helps physiotherapists create a calm treatment environment.

Q4. Define personality. Explain types and methods of personality assessment.

Definition

Personality is the unique and relatively stable pattern of thoughts, feelings, and behaviors that characterize an individual and distinguish them from others. It is consistent across time and situation.

The word comes from Latin "persona" meaning mask.

Gordon Allport: "Personality is the dynamic organization within the individual of those psychophysical systems that determine his characteristic behavior and thought."

Types of Personality

A. Type Theory (Hippocrates/Galen - Humoral Theory)

Type	Trait
Sanguine	Cheerful, optimistic
Choleric	Quick-tempered, active
Melancholic	Sad, withdrawn
Phlegmatic	Calm, slow

B. Sheldon's Somatotype Theory

Body Type	Personality
Endomorph	Sociable, relaxed (viscerotonia)
Mesomorph	Active, assertive (somatotonia)
Ectomorph	Introverted, restrained (cerebrotonia)

C. Eysenck's Personality Types (PEN Model)

Psychoticism (P)
Extraversion-Introversion (E)
Neuroticism-Stability (N)

D. Type A and Type B Personality

Type A	Type B
Competitive, hurried, aggressive	Relaxed, patient, easygoing
Higher risk of coronary heart disease	Lower cardiovascular risk

E. Big Five Personality Traits (OCEAN Model)

Openness to Experience
Conscientiousness
Extraversion
Agreeableness
Neuroticism

Methods of Personality Assessment

1. Observation Method

Direct observation of behavior in natural or controlled settings.
Used in clinical settings to assess patient personality during rehabilitation.

2. Interview Method

Structured or unstructured conversations to understand personality.
Used in clinical psychology intake assessments.

3. Self-Report Inventories (Questionnaires)

MMPI (Minnesota Multiphasic Personality Inventory): 10 clinical scales, used for psychopathology.
Eysenck Personality Questionnaire (EPQ)
NEO Personality Inventory (measures Big Five)
16 PF (Sixteen Personality Factor Questionnaire) by Cattell

4. Projective Techniques

Based on psychoanalytic theory.
Ambiguous stimuli are used; responses reveal unconscious aspects of personality.
Rorschach Inkblot Test: Patient interprets inkblots.
Thematic Apperception Test (TAT): Patient tells stories about ambiguous pictures.

5. Rating Scales

Others (teachers, colleagues) rate an individual on specific traits.

6. Behavioral Assessment

Direct recording of specific behaviors in frequency and duration.

Q5. Describe learning and memory in detail. Explain types of learning, process and types of forgetting.

Learning

Definition: Learning is a relatively permanent change in behavior or behavioral potential that results from experience or practice.

Characteristics of Learning:

Change in behavior
Relatively permanent
Results from experience (not maturation or drugs)

Types of Learning

1. Classical Conditioning (Pavlov)

Learning by association - neutral stimulus paired with unconditioned stimulus.

2. Operant/Instrumental Conditioning (Skinner)

Learning through consequences - reinforcement increases behavior; punishment decreases it.
Positive reinforcement: Add reward (giving a treat after exercise compliance).
Negative reinforcement: Remove unpleasant stimulus (removing pain during correct posture).

3. Trial and Error Learning (Thorndike)

Random responses are made until the correct response is found.
Law of Effect: Satisfying outcomes strengthen the response.

4. Observational/Social Learning (Bandura)

Learning by watching others (modeling).
Important for physiotherapy - patients observe correct exercise technique.

5. Insight Learning (Kohler)

Sudden understanding of a problem without trial and error.
Seen in higher animals and humans.

6. Latent Learning (Tolman)

Learning that occurs but is not immediately shown in behavior.

Memory

Definition: Memory is the mental process of encoding, storing, and retrieving information.

Stages of Memory (Atkinson-Shiffrin Model):

Sensory Memory: Very brief (1-2 sec), holds raw sensory data.
Short-Term Memory (STM): Holds 7±2 items for about 20-30 seconds.
Long-Term Memory (LTM): Relatively permanent storage with unlimited capacity.

Types of LTM:

Declarative (Explicit): Episodic (personal events) and Semantic (facts/knowledge).
Non-Declarative (Implicit): Procedural memory (skills, habits).

Forgetting

Definition: Forgetting is the failure to retain or retrieve information that was previously learned.

Process / Causes of Forgetting:

Decay Theory: Memory trace fades over time if not used (disuse).
Interference Theory:
- Proactive Interference: Old learning interferes with new learning.
- Retroactive Interference: New learning interferes with recall of old learning.
Retrieval Failure (Cue-Dependent Forgetting): Information is stored but cannot be accessed without the right cue.
Motivated Forgetting (Repression): Unconsciously pushing threatening memories out of awareness (Freud).
Organic Causes: Brain damage, Alzheimer's disease, amnesia.
Lack of Consolidation: Memory not properly encoded during learning.

Ebbinghaus Forgetting Curve: Forgetting is most rapid immediately after learning and then levels off gradually.

Q6. Explain schizophrenia and other major psychiatric disorders along with their management.

Schizophrenia

Definition: Schizophrenia is a severe, chronic mental disorder characterized by disturbances in thought, perception, emotion, and behavior. DSM-5 requires at least 2 symptoms for ≥1 month.

Symptoms - Positive Symptoms (excess/distorted functions):

Hallucinations: False perceptions without external stimulus (most common: auditory - hearing voices).
Delusions: Fixed false beliefs (persecution, grandeur, reference).
Disorganized Thinking: Loose associations, word salad, tangential thinking.
Disorganized/Catatonic Behavior

Negative Symptoms (diminished functions):

Alogia: Poverty of speech
Anhedonia: Loss of pleasure
Avolition: Lack of motivation
Affective Flattening: Reduced emotional expression
Asociality: Social withdrawal

Types of Schizophrenia (older DSM-IV classification):

Paranoid, Disorganized, Catatonic, Undifferentiated, Residual

Management of Schizophrenia:

Antipsychotic medications: Typical (Haloperidol, Chlorpromazine) and Atypical (Risperidone, Olanzapine, Clozapine).
Psychotherapy: Cognitive Behavioral Therapy (CBT) for psychosis.
Social Skills Training
Family Therapy and psychoeducation
Rehabilitation - vocational and social rehabilitation.

Other Major Psychiatric Disorders

1. Mood Disorders

Major Depressive Disorder: Persistent sadness, hopelessness, anhedonia, sleep and appetite changes. Treated with antidepressants (SSRIs) + CBT.
Bipolar Disorder: Alternating episodes of mania (elevated mood, grandiosity, decreased sleep) and depression. Treated with Lithium, valproate.

2. Anxiety Disorders

Generalized Anxiety Disorder (GAD): Excessive, uncontrollable worry. Treated with SSRIs, benzodiazepines, CBT.
Panic Disorder: Recurrent panic attacks.
Phobias: Intense fear of specific objects or situations.

3. Obsessive-Compulsive Disorder (OCD)

Obsessions (intrusive thoughts) + Compulsions (repetitive behaviors). Treated with SSRIs + Exposure and Response Prevention (ERP).

4. Post-Traumatic Stress Disorder (PTSD)

Following trauma: flashbacks, nightmares, hyperarousal. Treated with Trauma-focused CBT, EMDR.

5. Personality Disorders

Borderline, Antisocial, Narcissistic. Treated with Dialectical Behavior Therapy (DBT).

6. Delusional Disorder

Non-bizarre fixed delusions without other psychotic symptoms. Treated with antipsychotics.

Q7. Short Notes

A. Trial and Error Learning

Definition: A form of learning where an organism tries various responses randomly to a problem situation until one response is successful, and the organism gradually eliminates unsuccessful responses.

Thorndike's Experiment: A hungry cat was placed in a "puzzle box." The cat randomly tried various responses (scratching, biting, pushing) until it accidentally pulled a latch that opened the door. With repeated trials, the cat learned to pull the latch directly.

Thorndike's Laws:

Law of Effect: Response followed by satisfaction is strengthened; response followed by discomfort is weakened.
Law of Exercise: Practiced responses become stronger; unused responses become weaker.
Law of Readiness: Learning occurs when the organism is ready; forced learning causes frustration.

Characteristics:

Involves random, exploratory behavior
Goal-directed
Gradual learning - errors decrease over time
Motivation is required
Learning curve shows improvement over trials

Application in Physiotherapy: Patients learning new motor skills (e.g., walking with prosthetic limb) use trial and error - incorrect movements are gradually eliminated.

B. Memory and its Stages

Definition: Memory is the cognitive process of encoding, storing, and retrieving information.

Stages (Multi-Store Model - Atkinson & Shiffrin, 1968):

Stage 1 - Sensory Memory:

Duration: 0.5 to 3 seconds
Capacity: Large but brief
Type: Iconic (visual) and Echoic (auditory)
Raw sensory data briefly held before processing

Stage 2 - Short-Term Memory (STM):

Duration: 20-30 seconds without rehearsal
Capacity: 7 ± 2 chunks (Miller's Law)
Maintenance rehearsal transfers information to LTM
Working memory: Active manipulation of information

Stage 3 - Long-Term Memory (LTM):

Duration: Potentially lifetime
Capacity: Unlimited
Types:
- Declarative: Episodic (autobiographical events) + Semantic (general knowledge)
- Non-Declarative (Procedural): Motor skills, habits, conditioned responses
- Prospective: Memory for future events

Memory Processes: Encoding → Storage → Retrieval

Q8. Short Notes

A. Obsessive-Compulsive Disorder (OCD)

Definition: OCD is an anxiety-related disorder characterized by persistent, unwanted, intrusive thoughts (obsessions) and/or repetitive behaviors or mental acts (compulsions) performed to reduce anxiety.

Obsessions (intrusive, unwanted thoughts):

Fear of contamination (germs, dirt)
Fear of harming others
Need for symmetry/order
Unwanted sexual or religious thoughts

Compulsions (repetitive behaviors):

Excessive hand-washing
Checking (locks, switches)
Counting, repeating words
Arranging objects symmetrically

Diagnosis (DSM-5):

Obsessions and/or compulsions are time-consuming (>1 hour/day)
Cause significant distress or impairment
Not due to substance use or medical condition

Prevalence: About 2-3% of general population; equal in men and women.

Etiology: Serotonin dysregulation, OFC-basal ganglia circuit dysfunction, genetic factors.

Management:

Pharmacological: SSRIs (Fluoxetine, Fluvoxamine, Sertraline) - first-line medication
Psychological: Exposure and Response Prevention (ERP) - most effective therapy
CBT: Cognitive restructuring + ERP
Severe cases: Clomipramine (TCA), augmentation with antipsychotics

B. Illusion and Hallucination

Illusion:

Definition: A misperception or misinterpretation of a real external stimulus.
The stimulus exists but is wrongly perceived.
Types:
- Visual illusions (e.g., Muller-Lyer illusion, mirage)
- Auditory illusions
- Tactile illusions
Examples: Seeing a rope as a snake in dim light; hearing music in random noise.
Can occur in normal individuals under certain conditions (fatigue, emotion, drugs).
In psychiatry: Seen in delirium, intoxication, extreme anxiety.

Hallucination:

Definition: A false sensory perception occurring without any external stimulus. "Perception without object."
Types:
- Auditory: Hearing voices (most common in schizophrenia)
- Visual: Seeing things not present (common in drug intoxication, delirium)
- Olfactory: Smelling non-existent odors (temporal lobe epilepsy)
- Tactile: Feeling things on/under skin (cocaine - "formication")
- Gustatory: Taste hallucinations
- Hypnagogic: While falling asleep
- Hypnopompic: While waking up (can be normal)

Key Difference:

Feature	Illusion	Hallucination
Stimulus	Present (but misinterpreted)	Absent
Reality	Distorted reality	No reality base
Normality	Can be normal	Usually pathological

Q9. Short Notes

A. Group Therapy

Definition: Group therapy is a form of psychotherapy in which one or more therapists treat a small group of clients together at the same time (typically 5-12 members).

Founder: Joseph Pratt (1905) initiated group methods for tuberculosis patients.

Types of Group Therapy:

Psychoeducational Groups: Teaching coping skills (stress management)
Support Groups: Sharing experiences (cancer patients, AA)
Cognitive-Behavioral Groups: Applying CBT principles in a group setting
Psychodynamic Groups: Exploring unconscious patterns in relationships
Self-Help Groups: Peer-led (Alcoholics Anonymous)

Yalom's Therapeutic Factors (11 curative factors):

Installation of Hope - seeing others improve gives hope
Universality - "I'm not alone in my problems"
Imparting Information - sharing knowledge
Altruism - helping others boosts self-esteem
Corrective Recapitulation of Primary Family Group - resolving family conflicts
Imitative Behavior - modeling therapist and other members
Interpersonal Learning - learning from group interactions
Group Cohesiveness - sense of belonging
Catharsis - emotional release
Existential Factors - taking responsibility for one's life
Development of Social Skills

Advantages:

Cost-effective (multiple clients at once)
Reduces isolation and stigma
Peer feedback and support
Wider range of perspectives

Application in Physiotherapy: Group exercise sessions, chronic pain management programs, cardiac rehabilitation groups.

B. Difference between STM and LTM

Feature	Short-Term Memory (STM)	Long-Term Memory (LTM)
Duration	20-30 seconds	Potentially lifelong
Capacity	7 ± 2 items (Miller, 1956)	Unlimited
Encoding	Mainly acoustic (sound-based)	Mainly semantic (meaning-based)
Retrieval	Immediate, rapid	May require effort and cues
Forgetting	Displacement, decay	Interference, retrieval failure
Brain area	Prefrontal cortex	Hippocampus (consolidation), neocortex
Nature	Active, working memory	Relatively passive storage
Loss	Rapid unless rehearsed	Gradual; resistant to loss
Example	Remembering a phone number briefly	Remembering your childhood birthday

Transfer from STM to LTM:

Elaborative rehearsal (relating new info to existing knowledge)
Chunking (grouping items)
Mnemonics

Q10. Short Notes (2 marks each)

A. Intelligence Test

Definition: Intelligence tests are standardized psychometric tools designed to measure cognitive abilities such as reasoning, problem-solving, memory, and verbal ability.

Major Intelligence Tests:

Stanford-Binet Scale: Measures IQ across age groups. IQ = Mental Age/Chronological Age × 100.
Wechsler Adult Intelligence Scale (WAIS): Measures verbal and performance IQ.
Wechsler Intelligence Scale for Children (WISC)
Raven's Progressive Matrices: Non-verbal, culture-free test.

IQ Classification:

IQ Range	Category
130+	Very superior
120-129	Superior
90-109	Average
70-79	Borderline
Below 70	Intellectual disability

B. Mood Disorders

Mood disorders are psychiatric conditions characterized by significant disturbances in emotional state.

Types:

Major Depressive Disorder: Persistent depressed mood, loss of interest, fatigue, sleep/appetite changes, suicidal ideation (≥2 weeks).
Bipolar I: Full manic episodes + depressive episodes.
Bipolar II: Hypomanic episodes + major depressive episodes.
Dysthymia (Persistent Depressive Disorder): Mild but chronic depression (>2 years).
Cyclothymia: Mild mood cycling.

Management: Antidepressants (SSRIs, SNRIs), Mood stabilizers (Lithium), Antipsychotics, CBT.

C. Cognitive Behavioral Therapy (CBT)

CBT is a structured, goal-oriented, time-limited psychotherapy developed by Aaron Beck.

Core Principle: Thoughts (cognitions) → Feelings → Behaviors. Changing negative thoughts changes emotions and behavior.

Techniques:

Cognitive restructuring (identifying and challenging negative automatic thoughts)
Behavioral activation
Exposure therapy
Problem-solving
Relaxation training

Used for: Depression, anxiety, OCD, PTSD, eating disorders, chronic pain.

In Physiotherapy: CBT-based pain management helps patients with chronic musculoskeletal pain by addressing catastrophizing and fear-avoidance behavior.

D. Heredity and Environment

Heredity (Nature): Genetic factors inherited from parents that influence physical and psychological traits. Genes influence personality, intelligence, mental disorder susceptibility (e.g., schizophrenia heritability ~80%).

Environment (Nurture): External factors including family, culture, upbringing, education, and experiences that shape development.

Nature vs. Nurture: Not an either/or debate - most traits result from gene-environment interaction (G×E). Example: A genetic predisposition to depression may only manifest under environmental stress (diathesis-stress model).

Q11. Short Notes (2 marks each)

A. Motivation

Definition: Motivation is an internal state or condition that activates, directs, and sustains behavior toward a goal.

Types:

Intrinsic Motivation: Behavior driven by internal rewards (interest, satisfaction).
Extrinsic Motivation: Behavior driven by external rewards (money, praise).

Maslow's Hierarchy of Needs (1943):

Physiological needs (food, water, sleep)
Safety needs (security, shelter)
Love/Belonging (relationships)
Esteem (recognition, achievement)
Self-Actualization (realizing full potential)

In Physiotherapy: Patient motivation is key to compliance. Using goal-setting and positive reinforcement improves rehabilitation outcomes.

B. Nature vs. Nurture Controversy

This is a long-standing debate about whether human behavior, intelligence, and personality are determined more by:

Nature (genes, heredity, biology), OR
Nurture (environment, upbringing, culture, experience)

Extreme positions:

Nativists (Galton): Intelligence is primarily genetic.
Environmentalists (Watson): "Give me any infant and I can make them anything."

Modern View: Both interact. Twin studies show both genetic and environmental influences. Identical twins raised apart still show high similarity, but environment also plays a significant role.

Concept of Reaction Range: Genes set the potential range; environment determines where within that range an individual falls.

C. Causes of Forgetting

Decay/Disuse: Memory trace fades if not used over time.
Proactive Interference: Old memories interfere with retention of new information.
Retroactive Interference: New learning interferes with recall of old information.
Retrieval Failure: Lack of appropriate retrieval cues.
Motivated Forgetting (Repression): Unconsciously forgetting threatening material (Freud).
Consolidation Failure: Memory not properly encoded (e.g., concussion immediately after an event causing anterograde amnesia).
Organic Causes: Brain damage, Alzheimer's, Korsakoff's syndrome.

Ebbinghaus Forgetting Curve: Maximum forgetting in first 24 hours; spaced repetition reduces forgetting.

D. Theories of Emotion

1. James-Lange Theory: Stimulus → Physiological response → Emotion. "We feel sad because we cry." (Peripheral theory)

2. Cannon-Bard Theory: Stimulus → Simultaneous physiological arousal AND subjective emotion. (Thalamic theory - challenged James-Lange)

3. Schachter-Singer Two-Factor Theory: Emotion = Physiological arousal + Cognitive label. Context determines which emotion is felt.

4. Lazarus Cognitive-Appraisal Theory: Emotion follows cognitive appraisal of the situation. Primary appraisal (is it threatening?) → Secondary appraisal (can I cope?).

5. Papez-MacLean Limbic System Theory: Emotions are mediated by the limbic system (amygdala, hippocampus, hypothalamus).

Q12. Short Notes (2 marks each)

A. Need and Drive Motivation (Hull's Drive Reduction Theory)

Clark Hull (1943) proposed that behavior is motivated by biological drives.

Need: A biological deficiency or lack (e.g., hunger, thirst).

Drive: The psychological state of tension or arousal created by an unmet need (e.g., hunger need → drive state of hunger motivation).

Drive Reduction Theory:

Need → Drive → Motivated Behavior → Goal Achievement → Drive Reduction → Homeostasis

Example: Body needs water (need) → feeling of thirst (drive) → drinking water (behavior) → thirst quenched (drive reduction).

Primary Drives: Innate biological (hunger, thirst, sex, pain avoidance). Secondary Drives: Learned (money, fame, power - which reduce primary drives indirectly).

Limitation: Does not explain why people sometimes increase arousal (curiosity, thrill-seeking).

B. Delusional Disorder

Definition: A psychotic disorder characterized by the presence of one or more non-bizarre delusions lasting at least 1 month, without other psychotic symptoms (no hallucinations, disorganized behavior, or negative symptoms).

Types of Delusions:

Persecutory: Belief that one is being persecuted (most common type)
Grandiose: Belief in having extraordinary power/wealth
Erotomanic: Belief that a person (often of higher status) is in love with them
Jealous: Belief that partner is unfaithful
Somatic: Belief of having a physical illness or defect
Mixed/Unspecified

Key Feature: Functioning is not markedly impaired; behavior is not bizarre.

Management:

Antipsychotic medications (Pimozide, Risperidone)
CBT
Psychoeducation
Building therapeutic alliance (very challenging as patient lacks insight)

C. Personality Disorder

Definition: Personality disorders are enduring, inflexible, pervasive patterns of inner experience and behavior that deviate markedly from cultural expectations, cause distress, and are stable since adolescence or early adulthood.

DSM-5 Clusters:

Cluster A (Odd/Eccentric):

Paranoid PD: Distrust and suspicion
Schizoid PD: Detachment, restricted emotion
Schizotypal PD: Odd beliefs, magical thinking

Cluster B (Dramatic/Erratic):

Antisocial PD: Disregard for others' rights, deceitfulness
Borderline PD: Unstable relationships, identity, impulsivity, self-harm
Histrionic PD: Attention-seeking, theatricality
Narcissistic PD: Grandiosity, lack of empathy

Cluster C (Anxious/Fearful):

Avoidant PD: Social inhibition, fear of rejection
Dependent PD: Excessive need for care
Obsessive-Compulsive PD: Perfectionism, rigidity

Management: DBT (especially Borderline PD), psychotherapy, medications for symptoms.

D. Stress Management

Stress: A state of mental or emotional strain resulting from demanding circumstances. Selye described the General Adaptation Syndrome (GAS): Alarm → Resistance → Exhaustion.

Types of Stress:

Eustress: Positive, motivating stress
Distress: Negative, harmful stress

Stress Management Techniques:

Physical Techniques:

Regular exercise (releases endorphins)
Progressive Muscle Relaxation (PMR)
Deep breathing exercises (diaphragmatic breathing)
Yoga and meditation

Psychological Techniques:

CBT (cognitive restructuring)
Mindfulness-Based Stress Reduction (MBSR)
Biofeedback
Time management and problem-solving

Social Techniques:

Social support networks
Group therapy
Counseling

Lifestyle Modifications:

Adequate sleep (7-8 hours)
Healthy diet
Avoiding alcohol, caffeine, smoking

In Physiotherapy: Stress management is integral to treating musculoskeletal conditions as chronic stress exacerbates pain, delays healing, and reduces exercise compliance.
