PSYCH 111: Introduction to Psychology Final Exam

The Correct Answer is:

A. The body’s nonspecific physiological response to stress

General adaptation syndrome (GAS), proposed by Hans Selye, explains how the body reacts physiologically to any kind of stressor, regardless of its source. It involves three stages: alarm, where the body detects the stressor; resistance, where it tries to adapt and cope; and exhaustion, which occurs if the stress continues without relief. This model highlights that the body’s stress response is nonspecific, meaning it follows the same pattern for different stressors.

Why the other options are incorrect:

A conscious emotional reaction to specific stressful situations

This is incorrect because GAS refers to automatic physiological responses, not deliberate emotional reactions to stress.

A psychological coping strategy used to manage anxiety

This is incorrect because GAS describes the body’s biological response, not intentional coping mechanisms like problem-solving or relaxation techniques.

The complete absence of stress due to effective relaxation techniques

This is incorrect because GAS explains how the body responds to the presence of stress, not situations where stress has been eliminated.

The Correct Answer is:

C. 14%

In a large-scale study of 10,000 women, 14% screened positive for peripartum-onset depression, and nearly 20% reported thoughts of self-harm. These findings highlight the significant prevalence of postpartum depression and the need for early screening, intervention, and psychological support to protect maternal and infant health.

Why the other options are incorrect:

A. 5% – This underestimates the prevalence of peripartum-onset depression.

B. 10% – While closer, it is still lower than the reported 14% rate.

D. 25% – This is an overestimate compared to available statistics.

The Correct Answer is:

B. Correlational research method

Holmes and Rahe used the correlational research method to investigate how life stressors relate to physical health outcomes. They examined participants’ SRRS scores alongside records of illness to identify patterns between high stress levels and increased health risks. While this approach revealed a strong association between stress and illness, it does not prove causation, meaning other variables could also influence the observed outcomes.

Why the other options are incorrect:

A. Experimental research method

This is incorrect because Holmes and Rahe did not manipulate variables or use control groups to establish cause-and-effect relationships. Their research relied on observation and statistical associations rather than experimental designs.

C. Case study research method

This is incorrect because a case study focuses on in-depth analysis of one individual or a small group. Holmes and Rahe’s work involved a large number of participants and measured patterns across populations, making it unsuitable to classify as a case study.

D. Longitudinal research method

This is incorrect because a longitudinal method tracks the same individuals over a long period. While stress and illness relationships can be studied longitudinally, Holmes and Rahe’s original SRRS studies used cross-sectional correlational analysis, not long-term tracking.

The Correct Answer is:

A. Patterns of thoughts and behaviors that make individuals unique

Personality psychology focuses on understanding consistent patterns of thinking, feeling, and behaving that differentiate one individual from another. It studies traits, motivations, and emotional tendencies that shape a person’s identity and influence how they interact with the world. Unlike other branches of psychology, it is primarily concerned with individual differences rather than universal developmental stages or cultural impacts.

Why the other options are incorrect:

Physical growth and maturation across the lifespan

This is incorrect because physical changes are studied under developmental psychology, which focuses on growth, aging, and biological milestones rather than personality traits.

The influence of cultural norms on behavior

This is incorrect because understanding how culture shapes thoughts and actions is the focus of sociocultural psychology, not personality psychology.

Unconscious motives and internal conflicts

This is incorrect because analyzing hidden desires, dreams, and unresolved conflicts is primarily linked to psychoanalytic theory, especially Freud’s work, rather than personality psychology.

The Correct Answer is:

B. It means having two or more psychological disorders at the same time

Comorbidity refers to the co-occurrence of two or more psychological or medical disorders within the same individual. For example, a person may be diagnosed with both major depressive disorder and generalized anxiety disorder. Comorbidity is common in mental health and can make diagnosis and treatment more complex, often requiring integrated care approaches to address multiple conditions effectively.

Why the other options are incorrect:

It refers to hallucinations in schizophrenia

This is incorrect because hallucinations are symptoms of schizophrenia, not comorbidity. Comorbidity involves having more than one disorder, not a single symptom within a disorder.

It describes stress-related illnesses

This is incorrect because stress-related illnesses may coexist with other conditions, but comorbidity itself does not specifically refer to stress. Instead, it broadly describes the simultaneous presence of multiple disorders, whether stress-related or not.

It’s a treatment method for anxiety

This is incorrect because comorbidity is not a treatment method; it is a diagnostic concept. While comorbid conditions like anxiety and depression are often treated together, the term refers to the coexistence of disorders rather than any therapeutic technique.

The Correct Answer is:

C. Hypothalamus

The hypothalamus plays a central role in regulating the body’s stress response by activating the hypothalamic-pituitary-adrenal (HPA) axis. When a threat is perceived, the hypothalamus signals the pituitary gland and adrenal glands to release stress hormones like cortisol and adrenaline. These hormones trigger physiological changes such as increased heart rate, rapid breathing, and heightened alertness, preparing the body for the “fight-or-flight” response.

Why the other options are incorrect:

Amygdala

This is incorrect because while the amygdala helps detect threats and process emotions, it does not directly control the stress response. Instead, it signals the hypothalamus to activate the HPA axis, making the hypothalamus the primary controller.

Hippocampus

This is incorrect because the hippocampus is mainly involved in memory formation and learning. However, it does play a secondary role in regulating stress by helping the brain determine whether a situation is truly threatening, but it is not the main control center.

Cerebellum

This is incorrect because the cerebellum primarily coordinates movement, balance, and posture. It is not directly involved in managing the stress response or regulating the release of stress-related hormones.

The Correct Answer is:

B. The scientific study of behavior and mental processes

Psychology is defined as the scientific study of behavior and mental processes, which includes thoughts, emotions, and actions. It uses systematic observation, experimentation, and evidence-based methods to understand how individuals think, feel, and behave. Unlike philosophy or religion, psychology relies on data and research to explain human and animal behavior, making it a core discipline in both science and healthcare.

Why the other options are incorrect:

The study of supernatural phenomena

This is incorrect because psychology does not focus on unexplained, mystical, or supernatural occurrences. While human beliefs in such phenomena can be studied, psychology itself is grounded in science and evidence-based research, not paranormal or mystical interpretations of behavior or experiences.

The study of astrology and human fate

This is incorrect because astrology involves predicting personality traits or life events based on planetary positions, which lacks scientific evidence. Psychology, on the other hand, relies on measurable data, experimentation, and systematic methods to study mental processes and behavior. Astrology is considered a pseudoscience, whereas psychology is an established scientific field.

The exploration of spiritual beliefs

This is incorrect because psychology does not primarily focus on exploring religious or spiritual doctrines. While psychologists may study the effects of spirituality on mental health, psychology itself is broader and more scientific, encompassing emotions, cognition, development, and social behavior rather than focusing on personal faith or belief systems.

The Correct Answer is:

C. Control human thoughts and beliefs

Psychology aims to describe, explain, predict, and influence behavior using scientific methods. However, controlling human thoughts and beliefs goes beyond its ethical and scientific boundaries. While psychologists study how thoughts are formed and can influence behavior through interventions, their goal is not to control what people believe or think. Psychology focuses on understanding and supporting individuals, not manipulating their personal beliefs or autonomy.

Why the other options are incorrect:

Describe behavior

This is incorrect because describing behavior is one of psychology’s primary goals. Psychologists carefully observe and record behavior in order to identify patterns, understand actions, and establish a foundation for further study. This objective description allows researchers to compare behaviors across situations and populations without imposing personal judgments or assumptions.

Predict future behavior

This is incorrect because predicting behavior is another central goal of psychology. By analyzing existing data, theories, and observed patterns, psychologists aim to anticipate future actions or mental processes. Accurate predictions help in designing effective interventions, therapies, and strategies to improve mental health and overall well-being. Prediction relies on evidence, not assumptions or control over individuals.

Understand the causes of behavior

This is incorrect because understanding the causes of behavior is one of psychology’s key objectives. Psychologists study biological, cognitive, emotional, and social influences to explain why people behave as they do. This deeper understanding allows professionals to create strategies for behavioral change, therapy, and problem-solving while respecting personal autonomy and individuality.

The Correct Answer is:

A. It studies how thoughts influence our experiences and actions

Cognitive psychology is the area of psychology that focuses on studying mental processes, including thinking, memory, problem-solving, perception, and decision-making, and how these processes influence our behaviors and experiences. It explores the connection between thoughts and actions, helping us understand how people process information and use it to guide their responses.

Why the other options are incorrect:

It examines only unconscious motives and childhood conflicts

This is incorrect because studying unconscious desires and early experiences is the focus of psychoanalysis, not cognitive psychology.

It focuses exclusively on observable behaviors and learned responses

This is incorrect because this describes behaviorism, which studies measurable actions, while cognitive psychology explores internal thought processes.

It analyzes cultural and social factors shaping human behavior

This is incorrect because understanding cultural and environmental influences is part of the sociocultural perspective, whereas cognitive psychology emphasizes how thoughts affect actions and experiences.
