CH1. UNDERSTANDING THE BASICS OF PSYCHOLOGY

1. Which of the following is an assumption of arousal theory?

A. Highest levels of arousal are the most desirable

B. Optimal level of arousal exists for each person

C. Zero level of arousal is the most desirable

D. Highest level of arousal exists for various activities

Answer: B

Explanation:
Arousal theory, rooted in psychology, states that there is an optimal arousal level for each individual that enhances performance. Too little arousal can lead to boredom, while too much can cause stress or diminished performance. This principle is supported by the Yerkes-Dodson Law, which shows that moderate arousal levels are ideal for complex tasks.

2. The DSM-5 classification system:

A. Used 3 axes for diagnosis of mental disorders

B. Abandoned the multiaxial system

C. Used 4 axes of diagnosis of mental disorders

D. Maintained the multiaxial system with modifications

Answer: B

Explanation:
The DSM-5, published in 2013 by the American Psychiatric Association, eliminated the multiaxial system used in previous editions (DSM-IV). Instead of using separate axes for clinical disorders, personality disorders, and other factors, the DSM-5 integrates all relevant information into a single diagnostic framework. This change simplifies diagnosis and emphasizes a more holistic approach to mental health evaluation.

3. Which of the following best describes classical conditioning?

A. Learning based on reinforcement and punishment

B. A neutral stimulus becomes a conditioned stimulus

C. Observational learning through modeling

D. Problem-solving through sudden insight

Answer: B

Explanation:
Classical conditioning, first described by Ivan Pavlov, involves pairing a neutral stimulus (NS) with an unconditioned stimulus (US) that naturally elicits a response. Over time, the neutral stimulus becomes a conditioned stimulus (CS), producing a conditioned response (CR) even in the absence of the unconditioned stimulus. For example, a bell (NS) paired with food (US) can eventually cause salivation (CR) in dogs.

4. Psychology is defined as the scientific study of:

A. Mind and behaviour

B. Brain and emotions

C. Mental illness

D. Personality development

Answer: A

Explanation:
Psychology is the scientific study of the mind and behavior, encompassing how individuals think, feel, and act. It relies on empirical research and observation to understand processes like perception, cognition, emotions, and actions. This definition is widely accepted in academic and scientific contexts, including by organizations such as the American Psychological Association (APA).

5. The term ‘cognitive dissonance’ refers to:

A. A mismatch between attitudes and behaviours

B. A state of mental alertness

C. The balance between motivation and arousal

D. The process of learning through trial and error

Answer: A

Explanation:
Cognitive dissonance, introduced by Leon Festinger, occurs when there is a conflict between an individual’s attitudes, beliefs, or values and their behaviors. This inconsistency creates psychological discomfort, motivating the individual to reduce the dissonance by changing their attitude, behavior, or perception of the situation.

6. The term introspection’ was used by early psychologists to refer to:

A. Observing one’s own conscious thoughts

B. Studying behaviour through experiments

C. Analyzing unconscious desires

D. Examining physiological responses

Answer: A

Explanation:
Introspection, widely used by early psychologists like Wilhelm Wundt, involved systematically examining and reporting one’s own conscious thoughts, feelings, and perceptions. This method aimed to understand the structure of the mind, forming the foundation of the structuralist approach in psychology.

7. Which perspective in psychology emphasizes the influence of unconscious forces?

A. Cognitive

B. Humanistic

C. Psychoanalytic

D. Behavioural

Answer: C

Explanation:
The psychoanalytic perspective, developed by Sigmund Freud, emphasizes the role of unconscious forces, such as desires, memories, and conflicts, in shaping behavior and personality. It highlights processes like the id, ego, and superego, and unresolved childhood experiences, which influence thoughts and actions.

8. Who is known as the founder of psychoanalysis?

A. Carl Jung

B. Sigmund Freud

C. B.F. Skinner

D. John Watson

Answer: B

Explanation:
Sigmund Freud is recognized as the founder of psychoanalysis, a psychological theory and therapeutic method that focuses on exploring the unconscious mind. Freud introduced key concepts such as the id, ego, and superego, defense mechanisms, and the role of early childhood experiences in personality development.

9. The concept of self-actualization is most closely associated with which psychologist?

A. Carl Rogers

B. B.F. Skinner

C. Abraham Maslow

D. Jean Piaget

Answer: C

Explanation:
The concept of self-actualization is a central idea in Abraham Maslow’s Hierarchy of Needs. It represents the highest level of psychological development, where an individual realizes their full potential, seeks personal growth, creativity, and fulfillment. Maslow’s theory places self-actualization at the top of his five-tier model of human needs.

10. A researcher wants to examine the relationship between two continuous variables. Which of the following tests is the most appropriate?

A. Chi-square test

B. Pearson correlation

C. Independent sample t-test

D. Dependent sample t-test

Answer: B

Explanation:
The Pearson correlation coefficient is the most appropriate statistical test to examine the relationship between two continuous variables. It measures the strength and direction of the linear relationship between these variables, with values ranging from -1 to +1.

11. To compare the means of two independent groups, which statistical test is used?

A. Independent sample t-test

B. Dependent sample t-test

C. Chi-square test

D. ANOVA

Answer: A

Explanation:
The independent sample t-test is used to compare the means of two independent groups to determine if there is a statistically significant difference between them. It assumes that the two groups are independent of each other and normally distributed data.

12. Which statistical test is used when measuring the same group of participants at two different times?

A. Independent sample t-test

B. Dependent sample t-test

C. ANOVA

D. Pearson correlation

Answer: B

Explanation:
The dependent sample t-test (also known as the paired samples t-test) is used when the same group of participants is measured at two different times or under two different conditions. It assesses whether the mean difference between the two sets of observations is statistically significant.

13. A person experiences frequent panic attacks and avoids places where they fear a panic attack may occur. What is the most likely diagnosis?

A. Panic Disorder

B. Generalized Anxiety Disorder

C. Agoraphobia

D. Social Anxiety Disorder

Answer: A

Explanation:
Agoraphobia is an anxiety disorder characterized by the fear of being in places or situations where a panic attack might occur and where escape might be difficult or help may not be available. This leads to avoidance of crowded places, open spaces, or situations that trigger fear. It often develops following repeated panic attacks.

14. Rohit is excessively concerned about cleanliness and frequently washes his hands even when not necessary. What disorder does he suffer from?

A. Somatization Disorder

B. Conversion Disorder

C. Obsessive-Compulsive Disorder (OCD)

D. Hypochondriasis

Answer: C

Explanation:
Obsessive-Compulsive Disorder (OCD) is characterized by obsessions (repeated, intrusive thoughts) and compulsions (repetitive behaviors or mental acts). Rohit’s excessive concern about cleanliness and his frequent handwashing are compulsive behaviors driven by his fears or anxieties, a hallmark of OCD.

15. A person constantly worries about being evaluated negatively in social situations. What is the most likely diagnosis?

A. Panic Disorder

B. Social Anxiety Disorder

C. Agoraphobia

D. Generalized Anxiety Disorder

Answer: B

Explanation:
Social Anxiety Disorder is characterized by an intense fear of being evaluated negatively in social situations, leading to significant anxiety and avoidance of such situations. This fear is typically centered on the concern of embarrassment, judgment, or scrutiny by others.

16. In classical conditioning, a neutral stimulus becomes a conditioned stimulus by being paired repeatedly with a(n)

A. Conditioned response

B. Conditioned stimulus

C. Unconditioned stimulus

D. Operant response

Answer: C

Explanation:
In classical conditioning, a neutral stimulus (NS) becomes a conditioned stimulus (CS) by being repeatedly paired with an unconditioned stimulus (US). The unconditioned stimulus is a stimulus that naturally and automatically triggers a response without prior learning, such as food triggering salivation.

17. The cognitive revolution in psychology is most closely associated with the study of

A. brain structure

B. mental processes

C. observable behaviour

D. emotional responses

Answer: B

Explanation:
The cognitive revolution in psychology, which emerged in the mid-20th century, shifted the focus from behaviorism to the study of mental processes such as thinking, memory, problem-solving, perception, and language. It emphasized understanding how people process, store, and retrieve information.

18. In operant conditioning,…………. increases the likelihood of a behaviour being repeated.

A Punishment

B. Reinforcement

C. Extinction

D. Modeling

Answer: B

Explanation:
In operant conditioning, reinforcement is used to increase the likelihood of a behavior being repeated. It can be positive (adding a rewarding stimulus) or negative (removing an aversive stimulus) to strengthen a behavior. Punishment, on the other hand, decreases behavior.

19. The humanistic perspective in psychology emphasizes………

A. Unconscious drives

B. Observable behaviours

C. Free will and personal growth

D. Cognitive restructuring

Answer: C

Explanation:
The humanistic perspective in psychology emphasizes free will, personal growth, and the individual’s capacity for self-actualization.

Key figures include Abraham Maslow and Carl Rogers.

20. Down’s syndrome is characterized by the presence of an extra………. chromosome

A. X

B. 21

C. Y

D. 23

Answer: B

Explanation:
Down’s syndrome is caused by the presence of an extra 21st chromosome, resulting in trisomy 21. This extra genetic material leads to the physical and cognitive features associated with Down’s syndrome, such as developmental delays, characteristic facial features, and potential health issues.

21. Sigmund Freud proposed that the human psyche is composed of three parts: the id, ego, and………

A. unconscious

C. preconscious

B. superego

D. conscious

Answer: B

Explanation:
Sigmund Freud proposed that the human psyche is composed of three parts: the id, ego, and superego. The id represents primal desires, the ego represents reality and rationality, and the superego represents moral standards and societal rules. The interaction among these three shapes personality and behavior.

22. Maslow’s hierarchy of needs suggests that………… needs must be met before higher-level psychological needs.

A. safety

C. Esteem

B. Self-actualization

D. Physiological

Answer: D

Maslow’s hierarchy of needs is a five-tier model of human motivation. According to this model, physiological needs (such as food, water, shelter, and sleep) must be satisfied first before individuals can focus on higher-level psychological needs, such as safety, belonging, esteem, and self-actualization.

23. In cognitive psychology,…………mental processes involved in acquiring, storing, and retrieving information.

Select the answers from the codes given below:

A. 1, 2, 3

C. 1, 2, 4

B. 2, 3, 4

D. 1, 3, 4

Answer: A

According to Freud’s Theory of Psychosexual Stages, the stages of development are:

  1. Oral Stage (0-1 year) – Pleasure is derived from oral activities like sucking and biting.
  2. Anal Stage (1-3 years) – Pleasure is focused on controlling bowel movements and toilet training.
  3. Phallic Stage (3-6 years) – Children become aware of gender differences; concepts like Oedipus and Electra complex emerge.
  4. Latency Stage (6-puberty) – Sexual feelings are dormant, and children focus on social development.

The Genital Stage (puberty onward) is the final stage but is not listed in the options. Hence, C. 1, 2, 4 is correct.

30. The following are defense mechanisms according to Freud:

Select the answers from the codes given below:

A. 1, 2, 3

C. 1, 3, 4

B. 2, 3, 4

D. 1, 2, 4

Answer: C

According to Freud’s Theory of Defense Mechanisms, the following are recognized as defense mechanisms:

  1. Repression – Involves unconsciously pushing distressing thoughts and memories out of awareness.
  2. Projection – Attributing one’s own unacceptable thoughts or feelings to others.
  3. Denial – Refusing to accept reality or facts that are too uncomfortable.

Sublimation (option 2), although a defense mechanism, involves channeling unacceptable impulses into socially acceptable behaviors and is not listed as commonly central to Freud’s original defense mechanisms. Therefore, C. 1, 3, 4 is correct.

CH2. METHODS IN PSYCHOLOGICAL RESEARCH

1. Which of the following is a fundamental assumption of experimental research?

A. All variables can be controlled

B. Results can be generalized to all populations

C. Cause-and-effect relationships can be established

D. Correlation equals causation

Answer: C

Explanation:
Experimental research involves manipulating one variable (independent variable) while controlling others to observe changes in a dependent variable. This allows researchers to determine cause-and-effect relationships by isolating variables and observing their direct impact. Experimental designs ensure that observed outcomes are due to intentional manipulation, not other factors.

2. Which of the following is an advantage of using a double-blind study?

A. It reduces researcher bias

B. It ensures participant reliability

C. It eliminates all potential confounding variables

D. It increases the placebo effect

Answer: A

Explanation:
In a double-blind study, neither the participants nor the researchers know who is in the control or experimental group. This design minimizes researcher bias and ensures that expectations or preconceptions do not influence the results. It strengthens the validity of the study by ensuring objectivity.

3. What is the main purpose of a control group in an experiment?

A. To receive the treatment being tested

B. To serve as a baseline comparison for the experimental group

C. To manipulate variables

D. To ensure all participants receive equal treatment

Answer: B

Explanation:
The control group is not exposed to the independent variable being tested, while the experimental group is exposed to it. This allows researchers to use the control group as a baseline comparison to determine the effects of the independent variable by comparing outcomes between the two groups.

4. Which of the following is a common feature of naturalistic observation?

A. The researcher manipulates the environment

B. Participants know they are being observed

C. The researcher observes behaviour in a natural setting

D. It involves high levels of experimental control

Answer: C

Explanation:
In naturalistic observation, the researcher observes participants’ behaviour in their natural environment without manipulation or interference. This method provides authentic insights into behaviour as it occurs in real-life settings, enhancing ecological validity.

5. Which of the following research methods involves intensive examination of a single individual?

A. Survey

C. Longitudinal study

B. Case study

D. Cross-sectional study

Answer: B

Explanation:
A case study involves an intensive, in-depth examination of a single individual, group, event, or situation to gain detailed insights. It focuses on unique characteristics and experiences, providing comprehensive qualitative data.

6. Which type of validity refers to the extent to which the results of a study can be generalized to other situations and individuals?

A. Internal validity

B. Construct validity

C. External validity

D. Criterion validity

Answer: C

Explanation:
External validity refers to the extent to which the results of a study can be generalized to other situations, settings, populations, and times beyond the specific context of the study. It assesses the applicability of findings in real-world scenarios.

7. Which of the following is an essential characteristic of a hypothesis?

A. It must be falsifiable

B. It must be proven true

C. It should include all possible variables

D. It is always derived from a theory

Answer: A

Explanation:
A hypothesis must be falsifiable, meaning it can be tested and proven wrong through evidence. This allows researchers to conduct experiments or observations to determine its validity. A hypothesis does not need to be proven true; it is meant to be tested.

8. Which of the following best describes a longitudinal study?

A. A study that examines different individuals at the same time

B. A study that tracks the same individuals over a long period of time

C. A study that compares groups based on different variables

D. A study that manipulates a variable in a laboratory setting

Answer: B

Explanation:
A longitudinal study involves observing and collecting data from the same group of individuals over an extended period of time. This method is used to study changes and developments in behavior, health, or other variables over time.

9. Which of the following sampling methods ensures that every individual in the population has an equal. chance of being selected?

A. Convenience sampling

B. Random sampling

C. Purposive sampling

D. Snowball sampling

Answer: B

Explanation:
Random sampling ensures that every individual in the population has an equal chance of being selected. This method reduces bias and enhances the generalizability of the study results by providing each participant an equal opportunity to be included.

A. Chi-square test

B. Independent sample t-test

C. Dependent sample t-test

D. Pearson correlation

Answer: B

Explanation:
The independent sample t-test is used to compare the means of two independent groups to determine if there is a statistically significant difference between them. In this case, the two groups represent students exposed to two different teaching methods.

12. To test if the average reading score of a group of students changes after 6 weeks of intensive instruction, which test is most appropriate?

A. Chi-square test

B. Independent sample t-test

C. Dependent sample t-test

D. ANOVA

Answer: C

Explanation:
The dependent sample t-test (also known as a paired t-test) is used when comparing two related or paired sets of data (e.g., reading scores before and after the intervention for the same group of students). It assesses if there is a statistically significant change in the mean scores after the 6-week intensive instruction.

A. Somatization disorder

B. Conversion disorder

C. Hypochondriasis

D. Generalized anxiety disorder

Answer: A

Explanation:
Somatization disorder is a psychological condition where a person reports physical symptoms (such as anxiety, pain, or discomfort) that have no identifiable medical cause. These symptoms are not feigned and are linked to psychological factors rather than a physical illness.

14. A participant constantly exaggerates minor physical symptoms, believing they indicate serious diseases. What condition does the participant likely have?

A. Dysmorphic disorder

B. Conversion disorder

C. Hypochondriasis

D. Somatization disorder

Answer: C

Explanation:
Hypochondriasis (now often referred to as illness anxiety disorder) is a psychological condition where a person exaggerates minor physical symptoms, interpreting them as signs of a serious illness, despite medical evidence showing otherwise. This leads to persistent worry about having a serious disease.

15. A participant in a study is highly preoccupied with their appearance and perceives flaws in their physical appearance that others do not see. What disorder does this describe?

A. Dysmorphic disorder

B. Hypochondriasis

C. Somatization disorder

D. Conversion disorder

Answer: A

Explanation:
Dysmorphic disorder, or body dysmorphic disorder, is a psychological condition where an individual is highly preoccupied with perceived flaws in their physical appearance that are minor or nonexistent to others. This leads to significant distress and impairment in daily functioning.

16. In an experimental design, the variable that is manipulated by the researcher is called the……..

A. Dependent variable

19. A measure of how consistently a test produces the same results under the same conditions is called……..

A. Validity

C. Bias

B. Reliability

D. Error

Answer: B

  • Reliability refers to the consistency of a test’s results when administered under the same conditions.
  • A reliable test produces stable and repeatable outcomes over time.
  • It is different from validity, which measures how well a test assesses what it is intended to measure.

20. A……….variable is one that influences both the independent and dependent variables, causing a spurious association.

A. Confounding

B. Extraneous

D. Independent

C. Dependent

Answer: A

  • A confounding variable is one that affects both the independent variable (predictor) and the dependent variable (outcome).
  • This creates a false impression of a direct association between the independent and dependent variables.
  • Example: In a study linking exercise (independent) to heart disease (dependent), age might be a confounding variable as it influences both.

21. In psychological research, an operational definition is used to…….

A. Define variables in terms of how they are measured

B. Create a theory based on previous research

C. Ensure the experiment is ethical

D. Define the population sample

Answer: A

22. A sample that accurately reflects the characteristics of the population as a whole is called a…….. sample.

A. Biased

B. Random

C. Representative

D. Convenient

Answer: C

  • A representative sample reflects the characteristics of the population, ensuring findings can be generalized.
  • It is selected to include key traits (e.g., age, gender, ethnicity) in the same proportions as the population.
  • Example: A study on national voting patterns uses a sample that mirrors the demographic makeup of voters.

23. In research,……… the hypothesis states that there is no effect or relationship between variables.

A. Alternative

B. Directional

C. Null

D. Non-directional

Answer: C

  • The null hypothesis posits that there is no effect, relationship, or difference between variables.
  • It serves as the default assumption to be tested and potentially rejected in research.
  • Example: “There is no difference in test scores between students who study in groups and those who study alone.”

24. A researcher divides a group of participants into two conditions using a coin flip. This is an example of

A. Stratified sampling

B. Systematic sampling

C. Random assignment

D. Convenience sampling

Answer: C

  • Random assignment involves assigning participants to experimental conditions by chance, ensuring each participant has an equal likelihood of being placed in any group.
  • This minimizes bias and increases the validity of causal inferences.
  • Example: Using a coin flip to assign participants to either a treatment or control group.

25. In experimental research,…….. refers to the extent to which the results of the study can be attributed to the manipulations of the independent variable rather than confounding factors.

A. External validity

B. Construct validity

C. Internal validity

D. Ecological validity

Answer: C

  • Internal validity measures whether the observed effects in a study are due to the manipulation of the independent variable and not other factors.
  • It ensures the study’s results are reliable and free from confounding variables.
  • Example: Controlling for participant characteristics to isolate the effect of a new teaching method on test scores.
