Introduction to Psychiatry — MCQs

A researcher is studying whether a new knee implant is better than existing alternatives in terms of pain after knee replacement. She designs the study so that it includes all the surgeries performed at a certain hospital. Interestingly, she notices that patients who underwent surgeries on Mondays and Thursdays reported much better pain outcomes on a survey compared with those who underwent the same surgeries from the same surgeons on Tuesdays and Fridays. Upon performing further analysis, she discovers that one of the staff members who works on Mondays and Thursdays is aware of the study and tells all the patients about how wonderful the new implant is. Which of the following forms of bias does this most likely represent?

Question 101: Id, ego, and superego are terms coined by whom?

A. Sigmund Freud (Correct Answer)
B. Bleuler
C. Moral
D. Kraepelin

Explanation: **Explanation:** The correct answer is **Sigmund Freud**. In his **Structural Theory of the Mind** (1923), Freud proposed that the human psyche is composed of three distinct but interacting components: 1. **Id:** Operates on the **Pleasure Principle**. It is entirely unconscious and consists of instinctual drives (Libido/Thanatos). 2. **Ego:** Operates on the **Reality Principle**. It acts as a mediator between the Id, the Superego, and reality. It utilizes **Defense Mechanisms** to manage anxiety. 3. **Superego:** Operates on the **Morality Principle**. It represents internalized social norms, conscience, and the "ego ideal." **Why other options are incorrect:** * **Bleuler (Eugen Bleuler):** Known for coining the term **"Schizophrenia"** and describing the **"4 As"** (Association, Affect, Ambivalence, Autism). * **Morel (Bénédict Morel):** Introduced the concept of **"Démence précoce"** (early dementia), which was the precursor to the concept of schizophrenia. * **Kraepelin (Emil Kraepelin):** Known as the father of modern scientific psychiatry. He distinguished between **Dementia Praecox** (Schizophrenia) and **Manic-Depressive Psychosis** (Bipolar Disorder). **High-Yield Clinical Pearls for NEET-PG:** * **Topographical Model:** Freud also described the Mind in terms of **Conscious, Preconscious, and Unconscious**. * **Defense Mechanisms:** These are functions of the **Ego** used to resolve conflicts between the Id and Superego. * **Psychosexual Stages:** Freud’s developmental theory includes the Oral, Anal, Phallic, Latency, and Genital stages. * **Father of Psychoanalysis:** Sigmund Freud.

Question 102: Who coined the term 'id'?

A. Freud (Correct Answer)
B. Skinner
C. Weyker
D. Weyker

Explanation: **Explanation:** The term **'id'** (along with 'ego' and 'superego') was coined by **Sigmund Freud**, the father of psychoanalysis. In his **Structural Theory of the Mind** (1923), Freud described the 'id' as the most primitive part of the personality. It is present from birth, resides entirely in the **unconscious mind**, and operates on the **Pleasure Principle**, seeking immediate gratification of biological drives and instinctual needs (libido and aggression). **Analysis of Options:** * **A. Freud (Correct):** He developed the tripartite model of the psyche. While the 'id' is the instinctual core, the **Ego** operates on the *Reality Principle*, and the **Superego** acts as the *Moral Conscience*. * **B. Skinner:** B.F. Skinner was a pioneer of **Behaviorism**. He is best known for **Operant Conditioning** (learning through reinforcement and punishment), not psychoanalytic structures. * **C & D. Weyker:** This name is not associated with major psychiatric or psychological theories relevant to the NEET-PG curriculum. **Clinical Pearls for NEET-PG:** * **Topographical Model:** Freud’s earlier model consisting of the Conscious, Preconscious, and Unconscious. * **Defense Mechanisms:** These are functions of the **Ego** used to resolve conflicts between the Id and Superego. * **Primary Process Thinking:** The illogical, symbolic, and fantasy-oriented thought process associated with the **Id**. * **Father of Modern Psychiatry:** While Freud founded psychoanalysis, **Philippe Pinel** is often credited with the humane reform of psychiatric care, and **Emil Kraepelin** is considered the founder of modern scientific psychiatry/psychopharmacology.

Question 103: Who introduced cardiazol (metrazol) therapy for the production of seizures in the management of mental illness?

A. Adler
B. Meduna (Correct Answer)
C. Freud
D. Cerletti

Explanation: **Explanation:** The correct answer is **Meduna (Option B)**. **Ladislas J. Meduna**, a Hungarian psychiatrist, introduced **Cardiazol (Metrazol) convulsive therapy** in 1934. His work was based on the (now debunked) biological antagonism theory, which hypothesized that epilepsy and schizophrenia were mutually exclusive conditions. He believed that inducing seizures could "cure" schizophrenia. While Metrazol was effective in inducing convulsions, it was difficult to control, caused severe apprehension in patients, and often led to spinal fractures. It was eventually replaced by Electroconvulsive Therapy (ECT). **Analysis of Incorrect Options:** * **Adler (Option A):** Alfred Adler was a pioneer of **Individual Psychology**. He is best known for the concept of the "Inferiority Complex" and the importance of social interest, rather than somatic treatments. * **Freud (Option C):** Sigmund Freud is the father of **Psychoanalysis**. His approach focused on the unconscious mind, talk therapy, and dream analysis, not physical seizure induction. * **Cerletti (Option D):** Ugo Cerletti, along with Lucio Bini, introduced **Electroconvulsive Therapy (ECT)** in 1938. They used electricity instead of chemicals (like Cardiazol) to induce therapeutic seizures, which proved to be safer and more reliable. **High-Yield Clinical Pearls for NEET-PG:** * **First Pharmacological Convulsive Agent:** Camphor (used by Meduna before switching to Metrazol). * **Introduction of ECT:** Cerletti and Bini (1938). * **Insulin Coma Therapy:** Introduced by Manfred Sakel in 1933. * **Chlorpromazine (First Antipsychotic):** Introduced by Delay and Deniker in 1952, marking the beginning of the psychopharmacological revolution.

Question 104: According to Freud's structural model of the mind, what does the term "id" represent?

A. The emotional part of the mind (Correct Answer)
B. The rational part of the mind
C. The moral part of the mind
D. The conscience part of the mind

Explanation: **Explanation:** Sigmund Freud’s **Structural Model of the Mind** divides the human psyche into three components: the Id, Ego, and Superego. **1. Why Option A is Correct:** The **Id** is the primitive, instinctive, and **emotional** part of the mind. It operates entirely in the unconscious and is driven by the **Pleasure Principle**, seeking immediate gratification of all biological needs, drives, and lustful or aggressive impulses. It does not account for logic or social reality, making it purely emotional and impulsive. **2. Why Incorrect Options are Wrong:** * **Option B (The rational part):** This refers to the **Ego**. The Ego operates on the **Reality Principle**. It acts as a mediator between the unrealistic Id and the external world, using logic and reasoning to satisfy drives in socially acceptable ways. * **Options C & D (The moral/conscience part):** These refer to the **Superego**. The Superego develops last (around age 5) and represents the internalized ideals and moral standards of parents and society. It consists of the **Conscience** (which punishes with guilt) and the **Ego Ideal** (which rewards with pride). **Clinical Pearls for NEET-PG:** * **Pleasure Principle:** Governs the Id. * **Reality Principle:** Governs the Ego. * **Primary Process Thinking:** Primitive, illogical thinking associated with the Id (e.g., dreams, hallucinations). * **Secondary Process Thinking:** Logical, goal-oriented thinking associated with the Ego. * **Defense Mechanisms:** These are unconscious maneuvers employed by the **Ego** to protect the individual from anxiety arising from the conflict between the Id and Superego.

Question 105: Postponing attention to a conscious impulse or conflict is a mature defense mechanism known as?

A. Sublimation
B. Suppression (Correct Answer)
C. Humor
D. Anticipation

Explanation: **Explanation:** The correct answer is **Suppression**. In psychiatry, defense mechanisms are categorized by George Vaillant into four levels based on maturity. **Suppression** is a **Level IV (Mature)** defense mechanism. It involves the **conscious** and intentional decision to delay paying attention to a disturbing impulse, conflict, or emotion until a more appropriate time. Unlike unconscious mechanisms, the individual is aware of the stressor but chooses to "put it on the back burner" to remain functional in the present. **Analysis of Incorrect Options:** * **A. Sublimation:** This involves channeling socially unacceptable impulses into socially productive and acceptable behaviors (e.g., a person with aggressive urges becoming a professional boxer). It does not involve "postponing" but rather "transforming" the impulse. * **C. Humor:** This involves using comedy or irony to express feelings and thoughts without personal discomfort and without producing an unpleasant effect on others. It helps diffuse the intensity of a stressful situation. * **D. Anticipation:** This involves realistically planning or "practicing" for future inner discomfort or external stressful events (e.g., mentally preparing for a difficult exam). **NEET-PG High-Yield Pearls:** * **Suppression vs. Repression:** This is a common examiner favorite. **Suppression is conscious** (voluntary), while **Repression is unconscious** (involuntary). Repression is considered a Level II (Immature/Maladaptive) defense. * **Mature Defense Mechanisms (Mnemonic: SASH):** **S**ublimation, **A**ltruism, **S**uppression, **H**umor. (Anticipation is also included in this category). * **Altruism:** Dealing with stressors by dedicating oneself to meeting the needs of others (vicarious satisfaction).

Question 106: Who is the scientist credited with a Nobel Prize for his contributions to psychosurgery?

A. Erik Erikson
B. Alfred Adler
C. Manfred Bleuler
D. Egas Moniz (Correct Answer)

Explanation: **Explanation:** **Correct Answer: D. Egas Moniz** António Egas Moniz was a Portuguese neurologist who is credited as the founder of modern psychosurgery. He developed the **prefrontal leucotomy** (later known as lobotomy) in 1935 to treat severe psychiatric disorders like schizophrenia and refractory depression. For this contribution, he was awarded the **Nobel Prize in Physiology or Medicine in 1949**. He is also famously known for developing **cerebral angiography**. **Analysis of Incorrect Options:** * **A. Erik Erikson:** A developmental psychologist known for the **Theory of Psychosocial Development**, which outlines eight stages of the human life cycle (e.g., Trust vs. Mistrust). * **B. Alfred Adler:** A neo-Freudian who founded **Individual Psychology**. He is best known for concepts like the **Inferiority Complex** and the importance of birth order. * **C. Manfred Bleuler:** The son of Eugen Bleuler (who coined the term 'Schizophrenia'). Manfred is known for his extensive longitudinal studies on the course and prognosis of schizophrenia. **High-Yield Clinical Pearls for NEET-PG:** * **Psychosurgery Today:** While Moniz’s crude leucotomy is obsolete, modern stereotactic psychosurgery (e.g., **Deep Brain Stimulation** or **Cingulotomy**) is used as a last resort for treatment-resistant OCD and Depression. * **Eugen Bleuler (Father):** Coined the "4 As" of Schizophrenia (Affect, Autism, Ambivalence, Association). * **Walter Freeman:** The American neurologist who popularized the "transorbital" (ice-pick) lobotomy, though he did not win the Nobel Prize.

Question 107: Which among the following are defence mechanisms adopted when an individual is faced with problems or failures? I. Rationalization II. Regression III. Projection IV. Replacement Select the correct answer using the code given below :

A. I, III and IV
B. I, II and III (Correct Answer)
C. I, II and IV
D. II, III and IV

Explanation: ***I, II and III*** - **Rationalization**, **Regression**, and **Projection** are all classic defense mechanisms described in psychoanalytic theory. - These mechanisms are unconscious strategies used by the **ego** to reduce anxiety and protect the self from unacceptable thoughts or feelings, particularly when an individual faces problems or failures. *I, III and IV* - This option correctly identifies Rationalization and Projection, but incorrectly includes **Replacement**. - While "replacement" might refer to a form of **displacement** in some contexts, it is not a standard, recognized defense mechanism in the classic psychoanalytic framework. *I, II and IV* - This option correctly identifies Rationalization and Regression, but incorrectly includes **Replacement**. - **Replacement** is not a standard defense mechanism; instead, individuals might experience **displacement** where feelings are redirected to a safer target. *II, III and IV* - This option includes Regression and Projection, but misses **Rationalization** while incorrectly including **Replacement**. - **Rationalization** is a very common defense mechanism involving creating logical but false justifications for actions or beliefs.

Question 108: Which of the following are domains (or types) of learning ? 1. Affective learning 2. Cognitive learning 3. Physiological learning 4. Psychomotor learning Select the correct answer using the code given below :

A. 1, 2 and 4 (Correct Answer)
B. 2, 3 and 4
C. 1, 3 and 4
D. 1, 2 and 3

Explanation: ***Correct: 1, 2 and 4*** - The three generally recognized domains of learning are **cognitive**, **affective**, and **psychomotor**. - These domains describe the different types of learning outcomes and are used for classifying educational objectives. *Incorrect: 2, 3 and 4* - **Physiological learning** is not a standard, recognized domain of learning in educational theory. - While learning does involve physiological changes in the brain, "physiological" is not a classification for types of learning outcomes. *Incorrect: 1, 3 and 4* - This option correctly identifies affective and psychomotor learning but incorrectly includes **physiological learning** as a distinct domain. - **Cognitive learning**, which focuses on knowledge and intellectual skills, is a fundamental domain and is missing from this selection. *Incorrect: 1, 2 and 3* - This option correctly includes **affective** and **cognitive learning** but erroneously adds **physiological learning**. - It also omits **psychomotor learning**, which concerns physical skills and coordination, making it an incomplete classification of the standard learning domains.

Question 109: The attitude is a domain of:

A. affective learning (Correct Answer)
B. psychomotor learning
C. cognitive learning
D. temporal learning

Explanation: ***affective learning*** - The **affective domain of learning** deals with how we perceive, value, and feel about things, encompassing emotions, attitudes, values, and motivations. - Developing a particular **attitude** involves changes in feelings and emotions towards a subject or person, aligning directly with the objectives of affective learning. *psychomotor learning* - **Psychomotor learning** focuses on the development of physical skills and coordinated movements. - It involves the acquisition of **manipulative skills** and performance of actions, which is distinct from internal attitudes. *cognitive learning* - **Cognitive learning** primarily involves mental processes such as knowledge, comprehension, application, analysis, synthesis, and evaluation. - This domain relates to the acquisition and understanding of **factual information** and intellectual skills, not attitudes. *temporal learning* - **Temporal learning** is not a recognized standalone domain of learning in Bloom's Taxonomy or similar educational frameworks. - While learning often occurs over time, the term "temporal learning" doesn't describe a specific focus like attitudes, skills, or knowledge.

Question 110: A researcher is studying whether a new knee implant is better than existing alternatives in terms of pain after knee replacement. She designs the study so that it includes all the surgeries performed at a certain hospital. Interestingly, she notices that patients who underwent surgeries on Mondays and Thursdays reported much better pain outcomes on a survey compared with those who underwent the same surgeries from the same surgeons on Tuesdays and Fridays. Upon performing further analysis, she discovers that one of the staff members who works on Mondays and Thursdays is aware of the study and tells all the patients about how wonderful the new implant is. Which of the following forms of bias does this most likely represent?

A. Hawthorne effect
B. Pygmalion effect (Correct Answer)
C. Attrition bias
D. Golem effect

Explanation: ***Pygmalion effect*** - This bias occurs when higher expectations lead to an increase in performance. In this scenario, the staff member's positive reinforcement about the new implant likely instilled **higher patient expectations**, leading to better reported pain outcomes. - The patients' belief in the implant's superiority, influenced by the staff member, acted as a **self-fulfilling prophecy**, improving their subjective pain experience. *Hawthorne effect* - This effect describes how individuals modify an aspect of their behavior in response to their awareness of being observed. While patients were part of a study, their improved outcomes were specifically linked to a staff member's verbal influence, not solely the act of observation. - The improved pain outcomes stem from the **expectations created by the staff member's praise**, rather than a general awareness of being studied. *Attrition bias* - Attrition bias refers to systematic differences between groups in the loss of participants from a study. - This scenario describes differences in patient outcomes based on staff influence during the study, not due to **patients dropping out differentially** between groups. *Golem effect* - The Golem effect is the opposite of the Pygmalion effect, where lower expectations placed upon individuals lead to poorer performance from them. - In this case, the staff member's influence created **high expectations and positive outcomes**, not negative expectations leading to worse outcomes.
