Introduction to Psychiatry Practice Questions

Q: A 14-year-old boy cleans his room regularly to avoid his mother's scolding. This behavior is an example of which of the following?

Negative reinforcement. ### Explanation This question tests the fundamental concepts of **Operant Conditioning**, a theory of learning proposed by B.F. Skinner. **Why Negative Reinforcement is Correct:** In behavioral psychology, **reinforcement** always aims to *increase* the frequency of a behavior. * **Negative** means an aversive (unpleasant) stimulus is **removed or avoided** following a behavior. * In this scenario, the boy performs the behavior (cleaning the room) to **avoid** an unpleasant consequence (mother’s scolding). Because the removal of the scolding makes the cleaning behavior more likely to occur in the future, it is defined as negative reinforcement. **Analysis of Incorrect Options:** * **A. Positive Reinforcement:** This involves *adding* a pleasant stimulus (e.g., giving a chocolate) to increase a behavior. If the boy cleaned his room to get a reward, it would be positive reinforcement. * **C. Punishment:** The goal of punishment is to *decrease* a behavior. If the mother scolded the boy *after* he made a mess to stop him from being messy, that would be punishment. * **D. Extinction:** This is the gradual weakening and disappearance of a conditioned response when reinforcement is stopped (e.g., if the mother stops reacting entirely, the boy might eventually stop cleaning). **High-Yield Clinical Pearls for NEET-PG:** * **Reinforcement = Increase** behavior; **Punishment = Decrease** behavior. * **Positive = Add** stimulus; **Negative = Remove/Avoid** stimulus. * **Clinical Application:** Negative reinforcement plays a major role in **Obsessive-Compulsive Disorder (OCD)**. The patient performs a compulsion (e.g., handwashing) to remove the unpleasant stimulus (anxiety caused by obsessions). * **Avoidance Learning:** This is a specific type of negative reinforcement where a response prevents an aversive stimulus from occurring at all.

Q: Which of the following is NOT considered a paraphilia?

Lesbianism. **Explanation:** The correct answer is **A. Lesbianism**. **1. Why Lesbianism is the correct answer:** In modern psychiatry (ICD-11 and DSM-5), **Lesbianism** (female homosexuality) is recognized as a normal variation of human sexuality and is **not** classified as a mental disorder or a paraphilia. Historically, homosexuality was removed from the DSM in 1973 and the ICD in 1990. Paraphilias involve intense and persistent sexual interests in atypical objects, situations, or non-consenting individuals, whereas lesbianism refers to a sexual orientation. **2. Why the other options are incorrect:** * **B. Fetishism:** A paraphilia involving sexual arousal from the use of non-living objects (e.g., shoes, latex) or a highly specific focus on non-genital body parts. * **C. Frotteurism:** A paraphilic disorder characterized by achieving sexual arousal from touching or rubbing against a non-consenting person, typically in crowded public places. * **D. Voyeurism:** A paraphilia involving the act of observing an unsuspecting person who is naked, disrobing, or engaging in sexual activity to derive sexual pleasure. **Clinical Pearls for NEET-PG:** * **Paraphilia vs. Paraphilic Disorder:** A *paraphilia* is an atypical sexual interest, while a *paraphilic disorder* is a paraphilia that causes distress/impairment to the individual or involves harm/risk to others. * **Gender Distribution:** Most paraphilias are diagnosed almost exclusively in males. * **Treatment:** The mainstay of treatment for paraphilic disorders is **Cognitive Behavioral Therapy (CBT)** and, in severe cases, anti-androgens or SSRIs to reduce libido. * **Common High-Yield Paraphilias:** Exhibitionism (exposing genitals), Pedophilia (interest in children), and Masochism/Sadism (pain-related).

Q: Who disregarded the topographical theory of mind?

Freud. ### Explanation The correct answer is **Freud**. Sigmund Freud initially proposed the **Topographical Theory of Mind** in 1900, which divided the mind into three layers: the **Conscious, Preconscious, and Unconscious**. However, as he developed his theories, he found this model insufficient to explain mental conflicts and defense mechanisms. Consequently, in 1923, Freud **disregarded (or superseded)** the topographical model in favor of the **Structural Theory of Mind**, which introduced the concepts of the **Id, Ego, and Superego**. While he did not delete his previous work, he moved away from the topographical model as the primary framework for understanding the psyche. #### Analysis of Incorrect Options: * **Adler (Alfred Adler):** Known for **Individual Psychology**, he focused on the "Inferiority Complex" and "Striving for Superiority." He broke away from Freud but did not create or disregard the topographical theory. * **Erik Erikson:** Famous for the **Psychosocial Stages of Development** (8 stages). He expanded on Freud’s theories by focusing on social factors rather than psychosexual ones. * **Seligman (Martin Seligman):** Associated with the concept of **"Learned Helplessness,"** which is a cornerstone in the psychological understanding of Depression. #### NEET-PG High-Yield Pearls: * **Topographical Model:** Conscious (current awareness), Preconscious (accessible memory), Unconscious (repressed biological drives). * **Structural Model:** **Id** (Pleasure principle, present at birth), **Ego** (Reality principle, develops at 6 months), **Superego** (Morality principle, develops at age 5-6). * **The Unconscious:** Freud considered this the largest part of the mind, accessible via dreams and free association. * **Defense Mechanisms:** These are functions of the **Ego** used to manage anxiety arising from conflicts between the Id and Superego.

Q: Who was the scientist involved in the invention of psychosurgery?

António Egas Moniz. **Explanation:** **Correct Answer: B. António Egas Moniz** António Egas Moniz, a Portuguese neurologist, is credited with the invention of **psychosurgery**. In 1935, he performed the first **prefrontal leucotomy** (later known as lobotomy) to treat severe mental disorders like schizophrenia and depression. He believed that mental illnesses were caused by fixed, abnormal neural circuits in the frontal lobes that needed to be surgically severed. For this pioneering work, he was awarded the **Nobel Prize in Physiology or Medicine in 1949**. **Why other options are incorrect:** * **A. Jean Piaget:** A Swiss psychologist famous for his theory of **Cognitive Development** in children (Sensorimotor, Preoperational, Concrete operational, and Formal operational stages). * **C. Martin Seligman:** An American psychologist known for the concept of **"Learned Helplessness,"** which serves as a psychological model for depression. * **D. Eugen Bleuler:** A Swiss psychiatrist who coined the term **"Schizophrenia"** (replacing Dementia Praecox) and described the **4 A's** (Association, Affect, Ambivalence, and Autism). **High-Yield Clinical Pearls for NEET-PG:** * **Walter Freeman:** Refined Moniz’s technique into the "Transorbital (Ice-pick) Lobotomy," which became widely used in the US. * **Modern Psychosurgery:** Unlike the crude lobotomies of the past, modern psychosurgery is highly precise (stereotactic) and used only for treatment-resistant cases. Examples include **Stereotactic Cingulotomy** (most common for refractory OCD) and **Subcaudate Tractotomy**. * **Egas Moniz** also developed **Cerebral Angiography**, a landmark contribution to neuroradiology.

Q: Fixation is a concept related to:

Psychosexual stages of development. **Explanation:** **Fixation** is a core concept in **Sigmund Freud’s Theory of Psychosexual Development**. According to Freud, as a child progresses through stages (Oral, Anal, Phallic, Latency, and Genital), the libido (id energy) focuses on different erogenous zones. If a child experiences excessive gratification or significant frustration at a particular stage, a portion of the libido remains "stuck" there. This is termed **Fixation**, which influences adult personality traits and potential psychopathology (e.g., an "oral fixation" leading to smoking or overeating). **Analysis of Incorrect Options:** * **Option A (Psychosocial stages):** Proposed by **Erik Erikson**. It focuses on social crises (e.g., Trust vs. Mistrust) across the entire lifespan, rather than psychosexual energy. * **Option C (Cognitive stages):** Proposed by **Jean Piaget**. It describes how children develop intellectual mental models (Sensorimotor, Preoperational, Concrete, and Formal operational stages). * **Option D (Hierarchy of needs):** Proposed by **Abraham Maslow**. It is a motivational theory in psychology comprising a five-tier model of human needs, often depicted as a pyramid. **Clinical Pearls for NEET-PG:** * **Regression vs. Fixation:** While fixation is staying stuck at an earlier stage, **Regression** is a defense mechanism where an individual reverts to an earlier stage of development under stress. * **Anal Stage Fixation:** Often associated with "Anal-retentive" personality (obsessive cleanliness, orderliness, and stubbornness)—a high-yield link to **OCD traits**. * **Phallic Stage:** The period (3–6 years) where the **Oedipus and Electra complexes** occur; resolution is vital for developing the Superego.

Q: Operant conditioning where a painful stimulus is given to a child for decreasing a certain undesired behavior can be classified as:

Punishment. **Explanation:** This question tests the fundamental principles of **Operant Conditioning**, a theory developed by B.F. Skinner which posits that behavior is shaped by its consequences. **1. Why Punishment is Correct:** In behavioral psychology, **Punishment** is defined as any consequence that **decreases** the likelihood of a behavior recurring. * **Positive Punishment:** Adding an aversive/painful stimulus (e.g., a slap or a loud noise) to decrease a behavior. * **Negative Punishment:** Removing a pleasant stimulus (e.g., taking away a toy) to decrease a behavior. Since the question describes giving a painful stimulus to decrease an undesired behavior, it is a classic example of Positive Punishment. **2. Why Incorrect Options are Wrong:** * **Positive Reinforcement (A):** Involves **adding** a rewarding stimulus to **increase** a desired behavior (e.g., giving a chocolate for finishing homework). * **Negative Reinforcement (B):** Involves **removing** an aversive stimulus to **increase** a desired behavior (e.g., a child cleans their room to stop their mother’s nagging). *Note: Students often confuse this with punishment; remember that reinforcement always aims to increase behavior.* * **Negotiation (D):** This is a social/communication strategy, not a formal term within the framework of Operant Conditioning. **Clinical Pearls for NEET-PG:** * **Reinforcement** = Behavior Increases; **Punishment** = Behavior Decreases. * **Positive** = Stimulus is Added; **Negative** = Stimulus is Removed. * **Extinction:** The gradual weakening and disappearance of a conditioned response when it is no longer reinforced (e.g., ignoring a child's temper tantrum). * **Token Economy:** A therapeutic technique based on positive reinforcement where "tokens" (secondary reinforcers) are given for desirable behavior and can be exchanged for rewards.

Q: Anxiety is classified as which of the following?

Neurosis. ### Explanation **Correct Option: A. Neurosis** In traditional psychiatric classification (ICD-9 and earlier psychodynamic models), mental disorders are broadly divided into **Neurosis** and **Psychosis**. Anxiety is the hallmark of neurosis. * **The underlying concept:** In neurosis, the individual maintains **intact reality testing** and has **insight** into their condition (they recognize their symptoms as distressing and abnormal). The personality remains organized, and there are no hallucinations or delusions. Anxiety disorders, phobias, and OCD fall under this category. **Why other options are incorrect:** * **B. Psychosis:** This is characterized by a "loss of contact with reality." Key features include impaired reality testing, lack of insight, and the presence of delusions or hallucinations (e.g., Schizophrenia). In anxiety, the patient’s perception of reality remains functional. * **C. Personality Disorder:** These are enduring, pervasive, and inflexible patterns of inner experience and behavior that deviate markedly from cultural expectations (e.g., Borderline or Antisocial PD). While anxiety can be a symptom, it is not the defining classification for the state of anxiety itself. **High-Yield Clinical Pearls for NEET-PG:** * **Insight:** Present in Neurosis; Absent/Impaired in Psychosis. * **Reality Testing:** Intact in Neurosis; Impaired in Psychosis. * **Modern Classification:** While the term "Neurosis" was removed from the DSM-III onwards to favor descriptive categories (like Anxiety Disorders), it remains a frequent conceptual question in exams. * **Hierarchy of Diagnosis:** Always rule out organic causes (Medical/Substance-induced) before diagnosing a primary Anxiety Disorder.

Q: Which of the following is an example of a mature defense mechanism?

Suppression. **Explanation:** Defense mechanisms are unconscious psychological strategies used to cope with anxiety and internal conflict. They are categorized into four levels based on maturity (Narcissistic, Immature, Neurotic, and Mature). **Correct Answer: D. Suppression** Suppression is a **Mature** defense mechanism. It involves the **conscious** decision to delay paying attention to an emotion or need in order to cope with the present reality. For example, a student decides not to think about their exam results while attending a family function. Unlike other mechanisms, mature defenses are adaptive and help maintain psychological health. **Incorrect Options:** * **A. Intellectualization (Neurotic):** This involves using excessive abstract thinking or complex explanations to avoid experiencing disturbing feelings. It is a level 3 (neurotic) defense. * **B. Dissociation (Immature/Neurotic):** This involves a temporary, drastic modification of one’s character or sense of identity to avoid emotional distress (e.g., "out-of-body" experiences). It is generally classified as an immature or neurotic defense. * **C. Displacement (Neurotic):** This involves shifting an impulse or feeling from a threatening object to a safer, less threatening target (e.g., a doctor yelling at a nurse after being scolded by the Chief of Medicine). **High-Yield Clinical Pearls for NEET-PG:** * **Mnemonic for Mature Defenses (SASH):** **S**ublimation (channeling impulses into socially acceptable actions), **A**ltruism (service to others), **S**uppression (conscious postponement), and **H**umor. * **Suppression vs. Repression:** This is a common examiner favorite. **Suppression is conscious**, while **Repression is unconscious** (forgetting a trauma involuntarily). * **Reaction Formation:** Transforming an unacceptable impulse into its exact opposite (e.g., being overly kind to someone you dislike). This is a Neurotic defense.
