Psychological Disorders — NCERT Solutions

Given/Concept: Abnormality is defined using multiple criteria — deviation from social norms, statistical rarity, personal distress, dysfunction, and danger. The question asks whether a persistent pattern of deviant behaviour qualifies as abnormal.

Answer: Not necessarily — it depends on the context and criteria applied.

Elaboration:

1. Deviation from Social Norms:
Behaviour that violates the written or unwritten rules of a society is considered deviant. If such behaviour is long-standing and consistent, it may be labelled abnormal. For example, a person who persistently violates others' rights without remorse (as in Antisocial Personality Disorder) shows a long-standing deviant pattern that is considered a psychological disorder.

2. Limitations of Using Deviance Alone:

• Cultural Relativity: What is deviant in one culture may be normal in another. For example, hearing the voices of ancestors is considered spiritual in some cultures but may be labelled as hallucination in others.
• Historical Context: Norms change over time. Behaviours once considered deviant (e.g., left-handedness, homosexuality) are no longer classified as disorders.
• Eccentricity vs. Disorder: Some individuals consistently behave in unusual ways (e.g., artists, social reformers) but are not mentally ill. Their behaviour may be deviant but not dysfunctional or distressing.

3. Additional Criteria Needed:
For a long-standing deviant pattern to be considered truly abnormal, it should also involve:

• Distress to the individual or others
• Dysfunction — impairment in social, occupational, or other important areas
• Danger — risk of harm to self or others

4. Personality Disorders as an Example:
Personality disorders (e.g., Antisocial, Borderline) are characterised by long-standing, inflexible, and pervasive patterns of deviant behaviour that cause significant impairment. These are considered abnormal because they meet multiple criteria beyond mere deviance.

Conclusion: A long-standing pattern of deviant behaviour can be considered abnormal only when it is also dysfunctional, distressing, and/or dangerous. Deviance alone, without these additional criteria, is insufficient to label behaviour as a psychological disorder.

Given/Concept: Schizophrenia is a severe psychotic disorder characterised by disturbances in thought, perception, emotion, and behaviour. Its symptoms are classified as positive (excess or distortion of normal functions) and negative (diminution or loss of normal functions).

Answer: Changing topics frequently while speaking (known as loosening of associations or derailment) is a positive symptom of schizophrenia, as it represents a distortion of normal thought and speech processes — something added or in excess of normal functioning.

Other Symptoms of Schizophrenia:

A. Positive Symptoms (excesses — things that should not be present):

1. Delusions: False, fixed beliefs not based in reality. Types include:

• Delusions of persecution — belief that one is being plotted against
• Delusions of grandeur — belief that one has special powers or is a famous person
• Delusions of reference — belief that random events have special personal significance

2. Hallucinations: Sensory experiences without external stimuli. Most common are auditory hallucinations (hearing voices). Can also be visual, olfactory, or tactile.
3. Disorganised Thinking/Speech: Incoherent speech, loose associations, word salad (jumbled, meaningless speech), neologisms (made-up words).
4. Disorganised or Catatonic Behaviour: Unpredictable agitation, childlike silliness, or catatonia (stupor, rigidity, or purposeless motor activity).

B. Negative Symptoms (deficits — things that should be present but are absent):

1. Affective Flattening: Reduced range and intensity of emotional expression (blank facial expression, monotone voice).
2. Alogia: Poverty of speech — brief, empty replies.
3. Avolition: Inability to initiate and persist in goal-directed activities; apathy and lack of motivation.
4. Anhedonia: Inability to experience pleasure.
5. Social Withdrawal: Reduced social interaction and isolation.

Conclusion: Schizophrenia is a complex disorder with both positive symptoms (reflecting excess mental activity) and negative symptoms (reflecting loss of normal functioning). Frequent topic changes during speech is a positive symptom reflecting disorganised thinking.

Given/Concept: Dissociation refers to a disruption in the normally integrated functions of consciousness, memory, identity, emotion, perception, behaviour, and sense of self. It is the central feature of Dissociative Disorders.

Meaning of Dissociation:
Dissociation involves a splitting off or separation of certain mental processes from the main stream of consciousness. The individual 'disconnects' from their thoughts, feelings, surroundings, or even their own identity. It is often a defence mechanism against overwhelming stress or trauma.

Various Forms of Dissociative Disorders:

1. Dissociative Amnesia:

• Inability to recall important autobiographical information, usually of a traumatic or stressful nature.
• The memory loss is too extensive to be explained by ordinary forgetfulness.
• Dissociative Fugue is a subtype in which the person not only loses memory but also travels away from home and may assume a new identity.

2. Dissociative Identity Disorder (DID) — formerly Multiple Personality Disorder:

• The presence of two or more distinct personality states or identities that recurrently take control of the person's behaviour.
• Each identity may have its own name, age, gender, mannerisms, and memories.
• Transitions between identities are often triggered by stress.
• The person is usually unaware of the other identities.

3. Depersonalisation/Derealisation Disorder:

• Depersonalisation: Persistent feelings of being detached from one's own mental processes or body (feeling like an outside observer of one's thoughts, feelings, or body).
• Derealisation: Feelings that one's surroundings are unreal, dreamlike, or distant.
• Reality testing remains intact — the person knows these experiences are not real.

Causes:
Dissociative disorders are strongly associated with severe trauma, particularly childhood physical or sexual abuse, and are understood as a psychological escape from unbearable experiences.

Conclusion: Dissociation represents a fragmentation of the self as a response to trauma. Its various forms range from memory loss to complete separation of identity, all involving a disruption in the continuity of consciousness and self.

Given/Concept: Phobias are a type of anxiety disorder characterised by a persistent, excessive, and irrational fear of a specific object, situation, or activity that poses little or no actual danger. The fear leads to avoidance behaviour and significantly interferes with daily functioning.

Types of Phobias:

1. Specific (Simple) Phobia: Fear of a specific object or situation (e.g., snakes, heights, blood, flying).
2. Social Anxiety Disorder (Social Phobia): Fear of social situations where one may be scrutinised or embarrassed.
3. Agoraphobia: Fear of open or public spaces from which escape might be difficult.

Can a Simple Phobia (Fear of Snakes) Result from Faulty Learning?

Yes. Behavioural and learning theories explain phobias as the result of faulty or maladaptive learning. The fear of snakes (ophidiophobia) can develop through the following learning mechanisms:

1. Classical Conditioning (Pavlovian Learning):

• If a person had a frightening encounter with a snake (Unconditioned Stimulus → Unconditioned Response: fear), the snake becomes associated with fear.
• Subsequently, even the sight or thought of a snake (Conditioned Stimulus) triggers intense fear (Conditioned Response).
• Example: A child bitten by a snake develops a lasting fear of all snakes.

2. Observational Learning / Modelling (Vicarious Conditioning):

• A person may develop a phobia by observing someone else (e.g., a parent) react with extreme fear to snakes.
• The observer learns to associate snakes with danger without any direct experience.
• Example: A child who repeatedly sees their mother scream and run from snakes may develop the same phobia.

3. Operant Conditioning (Negative Reinforcement):

• Once the phobia develops, the person avoids snakes. This avoidance reduces anxiety, which reinforces the avoidance behaviour.
• The phobia is thus maintained because the person never confronts the feared object and never learns that it is not actually dangerous.

4. Information/Instruction:

• Repeated warnings ('snakes are deadly!') or frightening stories about snakes can also instil irrational fear.

Conclusion: A simple phobia like fear of snakes is indeed a product of faulty learning — through direct conditioning, vicarious learning, or reinforced avoidance. Behavioural therapies such as systematic desensitisation and exposure therapy, which work by unlearning these associations, are highly effective in treating phobias.

Given/Concept: Anxiety is a normal human emotion — a feeling of unease, worry, or fear about future events. It is adaptive when it motivates action. However, when anxiety becomes excessive, persistent, uncontrollable, and interferes with daily functioning, it becomes an Anxiety Disorder.

When Does Anxiety Become a Disorder?
Anxiety becomes a disorder when:

1. It is disproportionate to the actual threat or situation.
2. It is persistent — lasting for an extended period (e.g., 6 months or more in Generalised Anxiety Disorder).
3. It causes significant distress to the individual.
4. It leads to impairment in social, occupational, or other important areas of functioning.
5. It results in avoidance behaviour that restricts the person's life.

In short, normal anxiety is temporary and situation-specific, while an anxiety disorder is chronic, excessive, and debilitating.

Types of Anxiety Disorders:

1. Generalised Anxiety Disorder (GAD):

• Excessive, uncontrollable worry about a variety of everyday events (work, health, family) for at least 6 months.
• Accompanied by restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbance.

2. Specific Phobia:

• Intense, irrational fear of a specific object or situation (e.g., snakes, heights, blood, flying).
• The person recognises the fear is excessive but cannot control it.
• Leads to avoidance of the feared stimulus.

3. Social Anxiety Disorder (Social Phobia):

• Intense fear of social or performance situations where one may be judged, embarrassed, or humiliated.
• Leads to avoidance of social interactions.

4. Panic Disorder:

• Recurrent, unexpected panic attacks — sudden surges of intense fear accompanied by physical symptoms: palpitations, sweating, trembling, shortness of breath, chest pain, dizziness, fear of dying or losing control.
• Persistent concern about future attacks and their consequences.

5. Agoraphobia:

• Fear and avoidance of situations from which escape might be difficult or help unavailable during a panic attack (e.g., crowds, public transport, open spaces).

6. Separation Anxiety Disorder:

• Excessive fear or anxiety about separation from attachment figures, beyond what is developmentally appropriate.

Conclusion: While 'butterflies in the stomach' is a normal, even useful response to stress, anxiety crosses into disorder territory when it is chronic, disproportionate, and disabling. Anxiety disorders are among the most common psychological disorders and are highly treatable through psychotherapy (especially Cognitive Behavioural Therapy) and medication.
