- Abnormal behaviour is linked to brain and nervous system problems.
- Neurotransmitter imbalance can cause mental disorders.
- Hormonal and biochemical changes affect mood and behaviour.
- Mental disorders may have a genetic basis.
- MRI and PET scans support the biological explanation.

Key Points
Key Points: Concept of Abnormal Behaviour
- Modern life stress such as competition, unemployment, disasters, and rapid social changes increases psychological disorders.
- Psychological problems are rising due to changes in society, culture, and lifestyle.
- Abnormal behaviour means deviation from normal behaviour.
- Normal and abnormal behaviour differ in kind, not just in degree.
- Abnormal behaviour shows poor adjustment to environment and situations.
Key Points: Perspectives of Abnormal Behaviour> Statistical Perspective
- The statistical perspective defines abnormal behaviour as infrequent or rare behaviour in a population.
- According to this view, normal and abnormal differ in degree, not in kind, and are shown on a bell-shaped curve.
- Most people fall in the middle (normal range), while very low or very high extremes are considered abnormal or superior.
- Normality and abnormality are relative concepts, and there is no clear-cut boundary between them.
- Abnormal behaviour refers to actions that are socially inappropriate, culturally unexpected, and cause distress or poor adjustment.
Key Points: Perspectives of Abnormal Behaviour> Biological and Medical Perspectives
Key Points: Perspectives of Abnormal Behaviour> Psychological/Psychodynamic Perspective
- Biological factors alone cannot explain all mental disorders; psychological factors are also important.
- The behavioural model says abnormal behaviour is learned through experience, such as fear after a traumatic event.
- The cognitive model explains that faulty thinking patterns can cause anxiety, guilt, and low self-esteem.
- The psychodynamic perspective states that unconscious conflicts and repressed feelings can lead to mental disorders.
- A single negative experience (e.g., public humiliation) can create long-lasting fear and avoidance behaviour.
Key Points: Perspectives of Abnormal Behaviour> Socio-Cultural Perspective
- Socio-cultural factors like poverty, unemployment, low education, and prejudice can cause mental disorders.
- Negative and stressful environments increase the risk of mental health problems.
- Children who lack love, support, and basic needs (food, education) may develop stress and anxiety.
- Child labour and early life stress harm mental health and coping ability.
- Lack of social support and poor social conditions can lead to mental disorganization.
Key Points: Perspectives of Abnormal Behaviour> Diathesis-Stress Perspective
Key Points: Features of Abnormal Behaviour
- Abnormal behaviour is explained by the 4 Ds – Deviance, Distress, Dysfunction, and Danger.
- Deviance: Behaviour that is extreme, unusual, or against social norms (considering cultural differences).
- Distress: Behaviour that causes personal suffering, anxiety, or emotional discomfort for a long time.
- Dysfunction: Behaviour that interferes with daily activities and normal functioning in life.
- Danger: Behaviour that harms or threatens the safety of oneself or others.
Key Points: Classification of Psychological Disorders
- Classification of psychological disorders is necessary for proper diagnosis and specific treatment.
- Mental disorders are classified based on symptoms and syndromes (a group of related symptoms).
- Proper diagnosis helps in understanding causes and selecting correct treatment.
- Two major classification systems are ICD-10 (by WHO) and DSM (by American Psychiatric Association).
- ICD-10 is used worldwide and includes both physical and mental disorders.
- DSM (currently DSM-5) provides detailed criteria for diagnosis and is widely used by psychologists and psychiatrists.
- DSM classification is descriptive in nature and focuses on patterns of thoughts, emotions, and behaviours.
Key Points: DSM-IV Classification System
- DSM-IV is a classification system developed by the American Psychiatric Association for diagnosing mental disorders.
- It classifies disorders into many categories such as childhood disorders, mood disorders, anxiety disorders, psychotic disorders, and personality disorders.
- Major groups include Schizophrenia, Mood Disorders, Anxiety Disorders, Somatoform Disorders, Dissociative Disorders, Eating Disorders, and Substance-Related Disorders.
- It also includes disorders related to sleep, impulse control, sexual and gender identity, and adjustment problems.
- DSM-IV provides clear symptoms and diagnostic criteria for each disorder.
- It gives additional background information, including biological, age, sex, and cultural factors.
- The system helps psychiatrists and psychologists in accurate diagnosis and proper treatment planning.
Key Points: DSM-IV Classification System> DSM-IV Multiaxial System
- DSM-IV uses a five-axis system to classify mental disorders for a more detailed and complete diagnosis.
- Axis I includes major clinical disorders like schizophrenia, mood disorders, anxiety disorders, eating disorders, and substance-related disorders.
- Axis II covers personality disorders (e.g., antisocial, borderline, narcissistic) and mental retardation, which are long-term conditions.
- Axis III and IV consider general medical conditions and psychosocial/environmental problems (family, social, economic, occupational issues) affecting the disorder.
- Axis V measures overall functioning using the Global Assessment of Functioning (GAF) scale, which helps in treatment planning and predicting outcomes.
Key Points: DSM-IV Classification System> Schizophrenia Symptoms (as per DSM-IV-TR)
Key Points: Limitations of DSM-IV
- DSM-IV excels in description, fails in explanation of causes.
- Labelling creates stigma and clinical bias against patients.
- Gender bias reflects societal stereotypes, not biological reality.
- The categorical system ignores the symptom severity spectrum.
- The dimensional approach offers a more accurate disorder assessment.
- Universal framework justifies continued DSM-IV usage despite flaws.
Key Points: APA Criteria of Abnormal Behaviour
- According to the American Psychiatric Association (APA), abnormal behaviour must have clinical significance, causing distress, disability, or dysfunction in the individual.
- The behaviour should not be culturally accepted or culturally appropriate.
- Abnormal behaviour is maladaptive, meaning it creates problems for the person, family, or society.
- Culture plays an important role in deciding whether a behaviour is abnormal or not.
- The behaviour must be continuous, persistent, and serious, not temporary like normal emotional reactions.
Key Points: DSM-V Classification
- DSM-V is a standard classification manual used in abnormal psychology and psychiatry to define and describe mental disorders.
- A condition is called a mental disorder when it involves disturbances in behaviour, thoughts, or emotions, along with personal distress and impairment.
- The symptoms must arise from internal dysfunctions with biological or psychological causes.
- Axis I includes major clinical disorders like depression, anxiety disorders, schizophrenia, and substance dependence.
- Axis II covers personality disorders and intellectual disabilities, which are long-term and affect overall functioning.
- Axis III and IV consider general medical conditions and psycho-social/environmental stressors that influence the disorder.
- Axis V (GAF) gives a score from 1–100 to assess overall functioning; lower scores indicate more severe problems.
Key Points: Major Psychological Disorder> Anxiety Disorders
- Anxiety disorder is a long-lasting excessive worry or fear that interferes with daily life.
- GAD involves unrealistic and persistent worry with symptoms like restlessness, headache, and rapid heartbeat.
- A phobia is an intense and irrational fear of specific objects or situations, leading to avoidance.
- Panic disorder causes sudden panic attacks with breathlessness and fear of losing control or dying.
- Severe anxiety shows symptoms like sweating, dizziness, tremors, nausea, and sleep problems.
Key Points: Symptoms of Anxiety Disorders
- Anxiety is the body’s fight-or-flight response without real danger, causing physical and psychological symptoms.
- Common symptoms include sweating, rapid heartbeat, dizziness, worry, tension, and poor concentration.
- Panic disorder involves sudden, intense fear attacks with breathlessness and fear of dying or losing control.
- A phobia is an irrational and persistent fear of harmless objects or situations that interferes with daily life.

- Compulsive acts are performed to reduce anxiety caused by obsessive thoughts.
- Common compulsions include repeated hand washing, checking locks, counting, ordering, cleaning, and hoarding objects.
- These behaviours are persistent and interfere with normal daily activities.
- Obsessions and compulsions often occur together, but sometimes a person may have only obsessive thoughts.
- Mild obsessive-compulsive traits can help in jobs requiring accuracy and attention to detail (e.g., cashier, engineer, accountant).
- Severe compulsive behaviour can cause problems in jobs requiring public interaction and may need proper treatment.
Key Points: Mood Disorders
- Mood disorders involve extreme and long-lasting emotional changes that disturb normal life.
- They are more intense than normal mood swings and may include deep sadness or hopelessness.
- They require immediate medical and psychological treatment.

- Biological causes include genetics, brain chemistry imbalance, and stress-triggered mood changes (stronger genetic role in bipolar disorder).
- Cognitive causes include learned helplessness and Beck’s Negative Cognitive Triad (negative views of self, world, and future).
- Emotional & cultural factors include guilt and shame, which vary across cultures and societies.
- The psychoanalytic view links bipolar disorder to unresolved conflicts, low self-esteem, and relationship difficulties.
Key Points: Depressive Disorders
- Dissociative disorders affect memory, identity, and sense of reality.
- People may feel detached, confused about identity, or forget important events.
- Main types: Amnesia, Fugue, DID, and Depersonalization/Derealization.
- They are usually caused by severe stress or childhood trauma.
- They are not due to brain damage and occur across cultures.
Key Points: Dissociative Amnesia
- Dissociative Amnesia – Memory loss without brain damage, usually caused by trauma or stress.
- Memory loss may be localised or generalised, and the person may not recognise familiar people.
- Dissociative Fugue – Memory loss with loss of identity; person leaves home and may assume a new identity.
- Fugue is a defence mechanism against severe psychological stress.
- Dissociative Identity Disorder (DID) – Two or more distinct personalities in one person, often linked to early trauma.
Key Points: Anti-social Personality Disorder
- Meaning: ASPD is a Cluster B disorder marked by rule-breaking, impulsive behaviour, manipulation, and no guilt.
- Prevalence: Affects 5–15% of people; much higher in prisoners. In children, it appears as juvenile delinquency.
- Causes: Strong genetic influence (low serotonin, twin studies, ADHD), along with poor family environment and emotional deprivation.
- Impact: Individuals violate laws and social norms, posing risks to society; early identification is important.
Key Points: Avoidant Personality Disorder
- Meaning: AvPD involves fear of unfamiliar people, social inhibition, and feelings of inadequacy, but family relationships remain positive.
- Symptoms: Avoids strangers, feels embarrassed in groups, and struggles with peer relationships and studies.
- Causes: Linked to parental reinforcement of shyness, maternal anxiety, trauma, and low self-esteem.
- Risk Factors: More common in girls and in those with poor social skills or physical/medical difficulties.
- Treatment: Psychotherapy for both the child and parents to improve social skills and reduce avoidance.
Key Points: Histrionic Personality Disorder
- Meaning: HPD involves excessive emotionality and constant attention-seeking.
- Core Trait: Feels uncomfortable when not the centre of attention.
- Behaviour: Uses dramatic actions or appearance to gain attention and gets upset when ignored.
- Hidden Issue: Lacks true self-confidence and depends on others’ approval.
- Treatment: Psychotherapy (CBT, group therapy) is the main treatment; medication helps with related anxiety.

- Meaning: Dependent Personality Disorder (DPD) is marked by an excessive need for care, leading to clingy and dependent relationships.
- Core Traits: Individuals show pessimism, self-doubt, and emotional immaturity.
- Relationship Pattern: They expect constant support and attention and form overly dependent relationships.
- Emotional Reaction: When their needs are not met, they feel resentful and create relationship conflicts.
- Impact: Their excessive dependence creates problems in personal, medical, and workplace relationships.
Key Points: Passive and Aggressive Style Personality
- Horney vs Freud: Horney said gender differences come from social conditions, not biology.
- Basic Anxiety: Disturbed parent-child relationships create fear of helplessness and isolation.
- Coping Styles: Children develop rigid coping styles that become part of their personality.
- Passive & Aggressive: Passive style means obedience; aggressive style means fighting and asserting.
- Withdrawn Style: Child avoids people and represses emotions to escape anxiety.
Key Points: Major Psychological Disorder> Eating Disorders
- Eating disorders are serious problems related to eating habits and body image, often starting in adolescence.
- Anorexia nervosa involves fear of weight gain, very little eating, and severe weight loss.
- Bulimia nervosa involves binge eating followed by purging like vomiting or using laxatives.
- Binge eating disorder involves repeated uncontrolled eating without purging.
- Other types include pica (eating non-food items) and rumination disorder (re-chewing food).
Key Points: Anorexia Nervosa
Key Points: Bulimia Nervosa
Key Points: Behavioural and Developmental Disorders
- Meaning: Behavioural disorders involve persistent, age-inappropriate behaviours that disrupt daily activities and social functioning.
- Developmental Nature: These disorders begin in childhood or adolescence and may cause serious long-term consequences if neglected.
- Intellectual & Developmental Disorders: Include mental retardation (low intellectual functioning), autism, and learning disabilities.
- Behavioural & Emotional Disorders: Include ADHD, conduct disorder, anxiety disorders, and eating disorders.
- Other Childhood Disorders: Include gender identity disorder, tic disorders (e.g., Tourette’s), and elimination disorders (e.g., enuresis, encopresis).
Key Points: External Behaviour Disorders
- Classification: Childhood developmental problems are divided into externalising (undercontrolled) and internalising (overcontrolled) types. ADHD, ODD, and CD fall under externalising disorders.
- ADHD: Marked by inattention, impulsivity, and hyperactivity; more common in boys and causes academic difficulties despite normal intelligence.
- ODD: Characterised by persistent defiance, irritability, and argumentative behaviour beyond normal age limits; early intervention is important.
- CD: Involves serious, aggressive, deceitful, and rule-breaking behaviours with disregard for others’ rights.
- Causes & Treatment: These disorders are influenced by genetic and environmental factors and are managed through therapy, behaviour modification, family support, and early intervention.
Key Points: Internal Behaviour Disorders
- Separation Anxiety Disorder (SAD) is an internalising disorder where a child shows excessive fear of separation from parents or loved ones.
- It is normal in early childhood, but becomes a disorder when it is intense, persistent, and disrupts daily functioning.
- Symptoms include excessive worry about losing parents, refusal to leave home, nightmares about separation, and physical complaints like headaches or stomachaches.
- Causes include life stress, separation experiences, and genetic factors.
- Early professional help, especially Cognitive Behavioural Therapy (CBT), along with parental support, can reduce the severity of the disorder.
Key Points: Autism
- Autism (Autism Spectrum Disorder – ASD) is a neurodevelopmental disorder affecting communication and social interaction.
- Symptoms usually appear in early childhood (12–24 months).
- ASD is characterized by problems in communication and social relationships.
- Children show restricted and repetitive behaviours, such as repeated movements or rigid routines.
- Other features include poor eye contact, difficulty sharing emotions, and sensitivity to sensory stimuli.
- Causes are not fully known but may include genetic factors, family history, older parents, low birth weight, and environmental risks.
- There is no cure, but therapies like behaviour therapy, speech therapy, and occupational therapy help improve functioning.
Key Points: Major Psychological Disorder> Schizophrenia
- The term schizophrenia was coined by Paul Eugen Bleuler in 1911 from the Greek words schizein (split) and phren (mind), referring to fragmented thinking.
- It is a psychotic disorder that usually begins in adolescence or young adulthood and disturbs thoughts, emotions, perception, and behaviour.
- It is a complex cluster of disorders involving withdrawal from reality and problems in attention, perception, motivation, and social relationships.
- Important theorists include Meyer (life stresses), Sullivan (social isolation), Langfeldt (types of schizophrenia), and Schneider (first-rank symptoms).
- Symptoms include positive symptoms (delusions, hallucinations, disorganised thinking), negative symptoms (alogia, flat affect, avolition, social withdrawal), and psychomotor symptoms (catatonia).
Key Points: Symptoms of Schizophrenia> Positive Symptoms
- Positive symptoms are abnormal additions to behaviour such as hallucinations, delusions, disorganised thinking, bizarre behaviour, and incongruent affect.
- Hallucinations are false perceptions without real stimuli, commonly hearing voices or seeing things that are not present.
- Delusions are strong false beliefs, such as persecution, grandeur, or control over thoughts and actions.
- Disorganised thinking and speech involve loose associations, poor concentration, and invented words (neologisms).
- Bizarre behaviour and incongruent affect include unusual actions, catatonia, and emotions that do not match the situation.
Key Points: Symptoms of Schizophrenia> Negative Symptoms
- Negative symptoms refer to the absence of normal emotions and behaviours, leading to low functioning and poor quality of life.
- Common symptoms include flat affect, avolition, alogia, anhedonia, and social withdrawal.
- Patients often remain silent, isolated, and emotionally unresponsive.
- These symptoms affect daily life, causing poor performance, disturbed sleep, and neglect of hygiene.
- Negative symptoms usually last longer and respond less to treatment than positive symptoms.
Key Points: Types of Schizophrenia
- Schizophrenia – A mental disorder with abnormal thoughts, delusions, and hallucinations, causing personality decline.
- Catatonic – Extreme motor behaviour (rigid or violent); the most severe form.
- Disorganised – Silly behaviour, flat emotions, and unclear speech.
- Paranoid – Delusions of persecution/grandeur and hearing voices.
- Undifferentiated & Residual – Mixed symptoms, or social withdrawal after the acute phase.
Key Points: Origin and Causes of Schizophrenia
- Schizophrenia is a serious disorder affecting 1–2% of people.
- Genetic factors – Runs in families; multiple genes increase risk.
- Biochemical factors – Neurotransmitter imbalance contributes to symptoms.
- Brain dysfunction – Enlarged ventricles and low frontal lobe activity affect thinking.
- Psychological factors – Stressful family environment and criticism increase risk and relapse.
Key Points: Treatment and Management of Schizophrenia
- Early detection and diagnosis of schizophrenia are very important for better recovery.
- Treatment includes medication (to reduce symptoms like hallucinations) and psychiatric therapy.
- Around 30–40% recover completely, 30–40% partially, and 20–30% may remain chronic.
- Patient cooperation with doctors and regular treatment is essential for improvement.
- Family and social support in a warm and non-critical environment help reduce symptoms and improve adjustment.
Key Points: Concept of Psychotherapy
Key Points: Forms of Psychotherapy
- Forms: Psychotherapy includes group, family, marital, client-centred, and behaviour therapies.
- Types: Three main types — psychodynamic, behaviour, and existential therapy.
- Cause: Psychodynamic—inner conflicts; Behaviour—faulty learning; Existential—lack of life meaning.
- Treatment: Psychodynamic uses free association; Behaviour changes faulty behaviour; Existential supports self-growth.
- Clinical formulation: Explains the client’s problem and guides treatment.
Key Points: Psychodynamic Therapies
- Psychodynamic therapies assume psychological disorders arise from unresolved unconscious conflicts.
- Freud's personality model includes the Id (pleasure), the Ego (reality), and the Superego (morality) that balance impulses and conscience.
- Mental disorders occur when there is a conflict between the Id impulses and the Ego control, disrupting daily life.
- Freud’s psychoanalysis uncovers hidden unconscious conflicts to resolve psychological issues.
- Example: A student skipping studies (Id) feels guilty (Superego), and the Ego fails to balance, causing stress.
Key Points: Psychodynamic Therapies> Psychoanalysis
- Psychoanalysis, developed by Sigmund Freud, explains personality through the Id (desires), the Ego (reason), and the Superego (morality).
- Repressed desires in the unconscious mind cause anxiety and lead the Ego to use defence mechanisms.
- Therapy helps clients gain insight into hidden feelings and conflicts through self-reflection.
- It is an important psychological theory that introduced the concept of the unconscious mind.
- However, it is time-consuming, expensive, and lacks strong scientific evidence.
- Today, modified psychoanalytic therapies are used that focus on both past conflicts and present problems.
Key Points: Techniques used in Psychoanalysis
- Psychoanalysis, developed by Sigmund Freud, aims to bring unconscious conflicts and repressed desires into conscious awareness.
- Free Association allows the client to speak freely about thoughts and feelings, helping uncover hidden conflicts in the unconscious mind.
- Dream Interpretation analyzes the hidden meanings of dreams, which Freud called the “royal road to the unconscious.”
- Resistance occurs when clients unconsciously block painful memories or thoughts during therapy.
- Transference happens when clients transfer feelings from past relationships onto the therapist, helping reveal childhood conflicts and emotions.
Key Points: Alfred Adler's Psychodynamic Therapy
- Alfred Adler believed feelings of inferiority can cause mental disorders.
- Inferiority may lead to wrong beliefs and faulty thinking, affecting mental health.
- Adler’s theory, Individual Psychology, states that human behaviour is purposeful and goal-directed.
- Personal goals motivate behaviour and help overcome feelings of inadequacy.
- An inferiority complex from childhood must be overcome for healthy personality development.
Key Points: Sullivan's Psychodynamic Therapy
Key Points: Humanistic-existential Therapy> Client Centred Therapy
- Humanistic Approach: Mental disorders occur when the environment blocks personal growth and self-fulfilment.
- Developer & Aim: Developed by Carl Rogers to reduce negative self-image and anxiety.
- Basis: Based on self-actualisation; problems arise when a person’s growth is blocked, especially in childhood.
- Non-Directive Therapy: The therapist does not direct or interpret; the client explores their own feelings.
- Therapeutic Climate: Therapist provides empathy, congruence, and unconditional positive regard.
- Client’s Role: The client does most of the therapeutic work.
- Limitation: Effectiveness is not fully supported by empirical research.
Key Points: Behaviour Therapies
- Behaviour Therapy: Based on behaviourism, mental disorders occur due to faulty learning.
- Focus: Emphasises present behaviour, while the past is considered only to understand causes.
- Basis: Based on classical conditioning by Ivan Pavlov and instrumental conditioning by Edward Thorndike.
- Behavioural Analysis: Identifies malfunctioning behaviour, antecedent factors, and maintaining factors.
- Reinforcement: Uses positive reinforcement, negative reinforcement, token economy, and differential reinforcement.
- Techniques: Aversive conditioning, systematic desensitisation, modelling, and relaxation.
- Therapist’s Role: Conduct accurate behavioural analysis and choose suitable techniques to change behaviour.
Key Points: Behaviour Therapies> Systematic Desensitisation
- Meaning: A behaviour therapy used to treat phobias and anxiety by gradual exposure to feared situations while staying relaxed.
- Basis: Based on classical conditioning and reciprocal inhibition, where relaxation reduces anxiety.
- Steps: Involves relaxation training, anxiety hierarchy, and gradual desensitisation.
- Use: Effective for phobias, anxiety neuroses, and exam anxiety.
Findings of Ayllon and Houghton (1962)
- Ayllon and Houghton (1962) found that chronic schizophrenic patients resumed eating themselves when food was used as a reinforcer.
- The improvement brought about by the manipulation of food tended to generalise to social interaction among patients.
Key Points: Behaviour Therapies> Operant-Based Behaviour Therapy
Key Points: Aversion Therapy
Key Points: Flooding or Impulsive Therapy
- Flooding is a technique where the person is exposed to a very intense anxiety-provoking situation until the anxiety gradually reduces.
- It helps the client face fear directly instead of avoiding it, building tolerance to stress.
- It works by reducing autonomic (physical) anxiety responses, so the stimulus no longer creates fear.
- It is based on the idea that neurotic behaviour develops due to conditioned avoidance of fearful situations.
- It is used to treat phobias (e.g., fear of animals, water) and is often more effective than just imagining the feared situation.
Key Points: Modelling
- Modelling is a behaviour therapy based on social learning theory by Albert Bandura (1963), where patients learn by observing others.
- In this technique, the patient watches a model perform behaviours that they find difficult or fearful.
- It is used to treat phobias, such as fear of snakes, dogs, cats, spiders, and dark places.
- It is also used to improve interpersonal relationships by observing therapists’ interactions.
- Through continuous observation of models, fear reduces and new behaviours are learned.
Key Points: Assertive Training
- Assertive training is a behaviour therapy used to help people behave confidently in social situations.
- It reduces anxiety in interpersonal relationships and helps people express their rights and opinions.
- It is useful for non-assertive individuals who are shy, timid, or afraid to speak up.
- The therapist assesses non-assertiveness and gives practice situations to train the client to respond assertively.
- With practice, the person gains self-confidence and learns that assertiveness is different from aggression.
Key Points: Thought Stopping
- A behavioural technique used to control unwanted and repetitive thoughts.
- Developed by J. G. Taylor (1955) and later by Joseph Wolpe (1973).
- The therapist says “STOP” when the disturbing thought occurs; later, the client uses it themselves.
- “STOP” acts as an aversive cue, reducing the frequency of the unwanted thoughts.
- It helps reduce anxiety and interrupt intrusive thinking.

- Patients earn tokens for showing desirable behaviour, which can later be exchanged for rewards.
- It involves identifying undesirable behaviour and reinforcing desirable behaviour through tokens.
- Rewards may include food items, entertainment, privileges, or other incentives.
- The main aim is to develop socially acceptable and adaptive behaviour, especially in children and hospitalized patients.
