PSYCH 111: Introduction to Psychology Final Exam

The Correct Answer is:

B. Bulimia nervosa

Bulimia nervosa is classified as an eating disorder in the DSM-5. It involves recurring episodes of binge eating followed by compensatory behaviors such as vomiting, excessive exercise, or misuse of laxatives to prevent weight gain. Individuals with bulimia often experience intense guilt, shame, and distress about their eating habits and body image. Treatment typically includes cognitive-behavioral therapy, nutritional counseling, and sometimes medication.

Why the other options are incorrect:

Panic disorder

This is incorrect because panic disorder is classified as an anxiety disorder. It is characterized by sudden and repeated panic attacks, intense fear, rapid heartbeat, and shortness of breath, but it does not involve abnormal eating patterns.

Schizophrenia

This is incorrect because schizophrenia is a psychotic disorder involving hallucinations, delusions, disorganized thoughts, and impaired reality perception. While individuals with schizophrenia may have appetite changes, it is not classified as an eating disorder.

ADHD

This is incorrect because Attention-Deficit/Hyperactivity Disorder is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. It does not involve the abnormal eating behaviors or compensatory actions seen in eating disorders like bulimia nervosa.

The Correct Answer is:

C. Examination of mental processes like memory and problem-solving

The cognitive approach focuses on understanding mental processes such as perception, memory, thinking, decision-making, and problem-solving. It studies how people acquire, store, and retrieve information and how these processes influence behavior. This approach emerged as a reaction to behaviorism, emphasizing that internal thought processes are just as important as observable actions for understanding human behavior.

Why the other options are incorrect:

Focus on unconscious motives

This is incorrect because focusing on unconscious motives is the foundation of psychoanalysis, developed by Sigmund Freud. Unlike the cognitive approach, psychoanalysis emphasizes repressed desires, childhood experiences, and unconscious conflicts rather than studying conscious mental processes like reasoning and memory.

Study of observable behaviors only

This is incorrect because the exclusive study of observable behaviors is the focus of behaviorism, developed by psychologists like John B. Watson and B.F. Skinner. Behaviorists ignored mental processes, whereas the cognitive approach actively investigates how the mind processes and organizes information internally.

Analysis of chemical imbalances in the brain

This is incorrect because analyzing chemical imbalances is part of the biological approach to psychology, which focuses on brain structures, neurotransmitters, and genetics. While biological factors can influence thinking, the cognitive approach specifically studies how the mind processes information rather than focusing on brain chemistry or physiological mechanisms.

The Correct Answer is:

B. Difficulty discarding possessions, leading to excessive clutter that disrupts living spaces

Hoarding disorder is characterized by an ongoing inability to part with personal possessions, regardless of their value. Individuals accumulate excessive amounts of items that fill and clutter living spaces, often making areas like kitchens, bedrooms, or bathrooms unusable. People with this disorder struggle to discard items because they believe they may be useful later or have strong sentimental attachments, leading to significant emotional distress and impaired daily functioning.

Why the other options are incorrect:

A. Persistent fear of contamination leading to excessive cleaning rituals

This is incorrect because this describes a subtype of obsessive-compulsive disorder (OCD), not hoarding disorder. While hoarding was once linked to OCD, it is now recognized as a separate condition with different causes and treatment approaches.

C. Repetitive checking behaviors caused by intrusive and unwanted thoughts

This is incorrect because repetitive checking, such as ensuring doors are locked or appliances are off, is a common compulsion seen in OCD. Hoarding disorder, by contrast, focuses on difficulty discarding possessions rather than checking behaviors.

D. Preoccupation with perceived physical flaws, leading to mirror checking and hiding appearance

This is incorrect because this describes body dysmorphic disorder (BDD), not hoarding disorder. While both involve repetitive behaviors, BDD centers on imagined flaws in appearance, whereas hoarding involves excessive accumulation of items.

The Correct Answer is:

B. To improve functioning and well-being

The main goal of therapy is to enhance a person’s overall mental, emotional, and behavioral functioning while improving their quality of life. Through various approaches, such as cognitive-behavioral therapy, psychodynamic therapy, or humanistic counseling, therapy helps individuals develop coping strategies, manage symptoms, build resilience, and foster healthier relationships. While stress cannot be fully eliminated, therapy supports personal growth and well-being.

Why the other options are incorrect:

To completely eliminate all stress

This is incorrect because eliminating stress entirely is unrealistic. Therapy focuses on teaching coping skills and resilience, helping individuals manage stress effectively rather than removing it altogether.

To control clients’ decisions

This is incorrect because therapy promotes autonomy and self-awareness, not control. Therapists guide clients to make informed choices, but they do not impose decisions or take over personal agency.

To replace medication with counseling

This is incorrect because therapy does not automatically replace medication. For some mental health conditions, a combination of therapy and medication is the most effective approach. The best treatment depends on the individual’s needs and diagnosis.

The Correct Answer is:

B. To analyze how the structure and function of the nervous system generate behavior

Biological psychologists (also called biopsychologists or neuroscientists) study how the brain, spinal cord, neurotransmitters, hormones, and overall nervous system influence thoughts, emotions, and behaviors. They investigate the biological basis of mental processes and behavior, often using techniques like brain imaging, electrophysiology, and genetic studies to understand how the body and mind are connected.

Why the other options are incorrect:

To study cultural and social influences on behavior

This is incorrect because studying how culture and social context affect behavior is the focus of the sociocultural perspective, not biological psychology.

To focus on unconscious conflicts and repressed memories

This is incorrect because exploring hidden desires and early life experiences is the domain of psychoanalysis, not biological psychology.

To examine only learned behaviors through conditioning

This is incorrect because studying observable learning and reinforcement is the focus of behaviorism, while biological psychology emphasizes the nervous system and brain function in shaping behavior.

The Correct Answer is:

D. All of the above

Psychology students develop a wide range of skills, including critical thinking, applying the scientific method, and evaluating sources of information. Critical thinking helps students analyze problems logically, the scientific method teaches them to design and interpret research, and evaluating information ensures they can distinguish credible evidence from unreliable claims. These skills are essential for understanding human behavior and conducting psychological research effectively.

Why the other options are incorrect:

Critical thinking

This is incorrect because, while critical thinking is an important skill, it is not the only one psychology students develop; the question refers to multiple skills learned.

Use of the scientific method

This is incorrect because applying the scientific method is a major part of psychology, but the field also requires other competencies, including evaluating research quality and credibility.

Critical evaluation of sources of information

This is incorrect because evaluating information sources is vital, but it represents just one skill among several that psychology students gain, making “all of the above” the most accurate answer.

The Correct Answer is:

B. Clinical psychology

Clinical psychology focuses on assessing, diagnosing, and treating mental, emotional, and behavioral disorders. Clinical psychologists work with individuals experiencing issues such as anxiety, depression, trauma, and other psychological conditions. They use evidence-based therapeutic techniques, including cognitive-behavioral therapy and psychotherapy, to improve mental health and overall well-being. This subfield bridges research and practical application, making it one of the largest and most critical areas in psychology.

Why the other options are incorrect:

Developmental psychology

This is incorrect because developmental psychology studies how people grow and change across the lifespan, focusing on physical, cognitive, and emotional development. While it may explore mental health issues at different stages, its primary goal is understanding development, not diagnosing or treating psychological disorders.

Cognitive psychology

This is incorrect because cognitive psychology focuses on studying mental processes such as memory, problem-solving, perception, and decision-making. While cognitive theories often inform clinical treatments, this subfield itself does not specialize in diagnosing or treating mental health conditions.

Evolutionary psychology

This is incorrect because evolutionary psychology examines how natural selection and adaptation have shaped human behavior and mental processes over time. Its focus is on understanding psychological traits from an evolutionary perspective rather than diagnosing or treating mental disorders in individuals.

The Correct Answer is:

C. Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is classified in the DSM-5 as an anxiety disorder characterized by excessive, persistent, and uncontrollable worry about everyday situations. Individuals with GAD often experience symptoms such as restlessness, difficulty concentrating, fatigue, irritability, and sleep disturbances. The disorder affects daily functioning and quality of life, and diagnosis requires these symptoms to persist for at least six months.

Why the other options are incorrect:

Schizophrenia

This is incorrect because schizophrenia is classified under psychotic disorders, not anxiety disorders. It involves symptoms such as hallucinations, delusions, and disorganized thinking, which differ significantly from the persistent worry and tension seen in anxiety disorders.

Bipolar disorder

This is incorrect because bipolar disorder falls under mood disorders, characterized by alternating episodes of mania (high energy and impulsivity) and depression. While anxiety symptoms can occur alongside bipolar episodes, it is not classified as an anxiety disorder in the DSM-5.

Dissociative amnesia

This is incorrect because dissociative amnesia is categorized under dissociative disorders. It involves memory loss related to trauma or stress, but it does not primarily involve the chronic and excessive worry that defines anxiety disorders like GAD.

The Correct Answer is:

A. Helps individuals adjust internally and externally to threats, increasing chances of survival

According to Cannon, the fight-or-flight response is adaptive because it prepares the body to handle threats effectively. By activating the sympathetic nervous system and endocrine system, the body becomes physically ready to either confront the threat (“fight”) or escape it (“flight”). These rapid internal and external adjustments, such as increased heart rate and heightened alertness, improve survival chances and help individuals overcome immediate dangers.

Why the other options are incorrect:

Reduces emotional arousal and promotes relaxation during stressful situations

This is incorrect because the fight-or-flight response increases physiological and emotional arousal rather than reducing it. Relaxation occurs after the threat has passed.

Eliminates the need for cognitive appraisal when facing potential danger

This is incorrect because individuals still assess threats, even if unconsciously, before the fight-or-flight response is triggered. Cognitive appraisal remains part of the process.

Suppresses all physiological responses to maintain homeostasis during threats

This is incorrect because the fight-or-flight response involves heightened physiological activation, not suppression, to prepare the body for quick and effective action.
