How to Write an FRQ in Psychology

Mastering Free Response Questions (FRQs) can make a huge difference in your AP Psychology score. Unlike essays in other classes, psychology FRQs have a specific structure that's actually easier once you know the rules.

When answering an FRQ, always write your answers below the prompt, not within it. Respond to each part of the question separately rather than writing one long paragraph. Remember that FRQs make up 33% of your AP Psychology exam score, with 25 minutes allocated for each of the two questions.

💡 Don't waste time writing introductions or conclusions - dive straight into answering exactly what's asked!

For maximum points, be sure to:

• Define key psychological terms when they appear in the question
• Apply these terms directly to the specific scenario in the prompt
• Provide concrete examples that demonstrate your understanding
• Underline or bold key terms to help them stand out to graders
• Label each part of your answer (a, b, c, etc.)

Remember that the AP Psychology exam also includes 100 multiple-choice questions (66% of your score), so practicing both formats is essential for success.

Psychological Perspectives

Psychology approaches human behavior through several unique lenses, each offering different insights into why we think and act as we do.

The neuroscience perspective examines how the body and brain create our experiences. This approach asks questions like "How do nerve cells communicate?" and "How does our brain chemistry affect our moods?" When studying stress, for example, a neuroscientist might focus on how cortisol levels change in response to different situations.

The evolutionary perspective investigates how natural selection has shaped our behavioral tendencies over time. Rather than focusing on individual differences, evolutionary psychologists ask broader questions like "Why did humans develop fear responses?" and "How did social behaviors help our ancestors survive?"

Behavior genetics explores the fascinating relationship between our genes and environment. This perspective examines questions like "How much of our intelligence is inherited versus learned?" and "Why do some people develop depression while others don't?" Twin studies are particularly valuable in this field.

🧠 Each psychological perspective is like a different lens for viewing the same human behaviors - none is complete on its own, but together they give us a comprehensive understanding.

Other important perspectives include psychodynamic (focusing on unconscious drives), behavioral (examining how we learn observable responses), cognitive (studying how we process information), and social-cultural (investigating how behavior varies across different situations and cultural contexts).

Psychology's Seven Core Themes

Psychology is guided by several key principles that help us understand human behavior more completely. These themes serve as a framework for approaching psychological questions and research.

First, psychology is empirical - meaning it's based on systematic observation and experimentation rather than just theories. Researchers collect data to test hypotheses about behavior and mental processes, ensuring findings have real evidence behind them.

Second, psychology is theoretically diverse. Different perspectives often explain the same behavior in completely different ways. For instance, depression might be viewed as a chemical imbalance (biological), learned helplessness (behavioral), or social isolation $social-cultural$.

Third, behavior is shaped by our cultural heritage. The values, beliefs, and customs we grow up with significantly influence how we think and behave. What's considered normal or abnormal varies widely across different societies.

👉 Remember that psychology recognizes behavior has multiple causes - biological, psychological, AND social factors almost always work together!

Psychology also recognizes that behavior has multiple causes, is influenced by both heredity and environment, and that our experience of the world is highly subjective. Additionally, psychology exists within a sociohistorical context - the questions researchers ask and how they interpret results are influenced by the time period and society they live in.

Understanding the distinction between basic research (which expands knowledge) and applied research (which solves practical problems) helps you see how psychological discoveries move from the laboratory into real-world applications in schools, workplaces, and clinical settings.

Research Methods in Psychology

Good psychological research helps us avoid common thinking traps like hindsight bias $the "I-knew-it-all-along" phenomenon$ and overconfidence (thinking we know more than we actually do).

Researchers use several methods to study behavior. A case study examines one person or a small group in great depth. While this provides rich information about individuals, the findings can't be generalized to others, and researcher bias can influence interpretations.

Surveys gather self-reported attitudes or behaviors from a sample of people. Their advantage is collecting information about almost anything at low cost. However, even slight wording changes can dramatically affect results, and getting a truly random sample is challenging.

Naturalistic observation involves watching and recording behavior in real-world settings without interference. This method captures genuine behavior but makes it difficult to determine the causes behind what's observed.

🔍 The correlation coefficient tells you two important things: the strength of a relationship (how closely two variables are linked) and the direction (positive or negative).

A correlation shows how two variables relate to each other. When measured, this relationship is expressed as a correlation coefficient ranging from +1.00 (perfect positive correlation) to -1.00 (perfect negative correlation). Remember that correlation doesn't prove causation - just because two things are related doesn't mean one causes the other. Illusionary correlation happens when we "see" relationships that aren't actually present in the data.

Unlike correlational studies, experiments manipulate an independent variable to observe its effects on a dependent variable. By randomly assigning participants to experimental and control groups, researchers can determine cause and effect relationships.

Neural and Hormonal Systems

Our feelings and behaviors have biological underpinnings that biological psychology investigates. Understanding the nervous system begins with the neuron - your brain's basic building block.

A neuron has several key parts: dendrites receive messages from other cells in chemical form, while the cell body (soma) serves as the life support center. The axon passes messages away from the cell body using electrical charges. Some neurons have a myelin sheath covering the axon, which speeds up neural impulses. At the end of the axon are terminal branches with buttons that form junctions with other cells.

Neurons don't actually touch each other - there's a tiny gap called a synapse between them. This is where communication happens in a fascinating way: electrical inside the neuron, chemical outside. When a neuron fires, it follows an all-or-nothing response - it either fires completely or not at all.

💡 The action potential is like flipping a light switch - it's either completely on or completely off, with no in-between states!

The process of neural firing involves several steps: resting potential (neuron at rest), depolarization (charge building), action potential (threshold reached, charge fired), and repolarization (return to resting state).

Neurotransmitters are the chemical messengers that cross the synaptic gaps. After delivering their message, they're often reabsorbed by the sending neuron in a process called reuptake. Early researchers believed brain areas could be mapped by studying skull shapes (phrenology), but we now know brain functioning is much more complex. Modern science has revealed that environmental factors can affect how genes are expressed through epigenetics.

Neurotransmitters and the Nervous System

Your brain relies on several key neurotransmitters to function properly. Acetylcholine is involved in movement, learning, memory, and sleep. Having too little in the hippocampus has been linked to Alzheimer's disease. Dopamine affects movement, mood, attention, and learning, with imbalances associated with conditions like schizophrenia and Parkinson's.

Norepinephrine influences eating, consciousness, and stress responses. Epinephrine (adrenaline) controls energy and metabolism, with too much causing restlessness and anxiety. Serotonin plays a crucial role in mood regulation, sleep, and appetite - many antidepressants work by increasing its availability. GABA inhibits excitation, creating a calming effect, while endorphins reduce pain and create feelings of pleasure.

Chemicals can interact with these systems in two main ways: agonists stimulate a response by binding to receptor sites, while antagonists block responses by occupying receptor sites.

🧠 Think of your nervous system like your body's internet - the central nervous system is the main server, while the peripheral nervous system is the network carrying messages to and from all your devices!

Your nervous system has two main divisions. The central nervous system consists of your brain and spinal cord - your body's command center. The peripheral nervous system connects the central nervous system to the rest of your body through sensory neurons (carrying information inward) and motor neurons (carrying commands outward).

The peripheral nervous system further divides into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which manages involuntary functions. The autonomic system has two branches: the sympathetic (arousing, "fight or flight") and parasympathetic (calming, "rest and digest") systems.

Working alongside the nervous system, your endocrine system sends chemical hormones through the bloodstream to affect distant tissues.

Neurotransmitters and Brain Examination Methods

Different neurotransmitters affect your thoughts, emotions, and behavior in specific ways. Serotonin influences mood, sleep, and impulsivity, with too little linked to depression and anxiety disorders. GABA acts as a natural tranquilizer, with imbalances potentially causing either excessive sedation or anxiety. Endorphins create natural pain relief and feelings of pleasure.

Chemical messengers in the brain can be affected by agonists (molecules that stimulate responses) and antagonists (molecules that block responses). Understanding these interactions helps explain how many medications work.

Scientists use several methods to examine brain functioning. Lesions involve removing or destroying brain tissue to study the effects. Electroencephalograms (EEGs) detect brain waves through electrical outputs and are particularly useful in sleep research. CT scans provide 3D X-rays that can locate brain tumors but don't reveal much about function.

⚡ The case of Phineas Gage revolutionized our understanding of the brain. When a railroad accident damaged his frontal lobe in 1849, his personality changed significantly - proving that different brain regions control different aspects of who we are.

More advanced techniques include Magnetic Resonance Imaging (MRI), which produces detailed brain images using magnetic fields, and Positron Emission Tomography (PET scans), which measure chemical activity in the brain. The most sophisticated method combines these approaches in functional MRI (fMRI), which shows both structure and activity.

Brain imaging has revealed that your brain is organized into distinct regions with specialized functions. Scientists continue to discover how these areas work together to create your thoughts, emotions, and behaviors, challenging earlier views that brain functions were more generalized.

Parts of the Brain

Your brain has a remarkably organized structure, with different regions handling specific functions. The hindbrain, positioned just above your spinal cord, controls basic biological functions. Within it, the medulla oblongata manages critical processes like breathing and heart rate - damage here is fatal. The pons connects the hindbrain to higher regions and helps coordinate facial expressions, while the cerebellum ("little brain") coordinates fine muscle movements.

The midbrain bridges lower and higher brain regions, coordinating movements with sensory information. Its reticular formation controls arousal and attention - it's what keeps you alert and focused.

Your forebrain is what makes you distinctly human and includes three major structures. The thalamus acts as your brain's switchboard, receiving sensory signals (except smell) and routing them to the appropriate areas. The limbic system processes emotions and memories, with the hypothalamus regulating body temperature, hunger, thirst, and sexual arousal, while the hippocampus stores memories and the amygdala handles emotional responses, especially fear and anger.

🧠 Your cerebral cortex may look wrinkled and uniform, but it's actually divided into specialized regions that work together like departments in a company!

The cerebral cortex, your brain's outer layer of "gray matter," contains densely packed neurons supported by glial cells. It's divided into two hemispheres connected by the corpus callosum. Each hemisphere primarily controls the opposite side of your body (contralateral control).

Your brain has four major lobes: the frontal lobe (abstract thought, motor control, and Broca's area for speech production), the parietal lobe (sensory processing), the occipital lobe (vision), and the temporal lobe (hearing and language comprehension through Wernicke's area).

Vision and Sensation

Your eyes are remarkable organs that transform light into neural signals your brain can interpret. Light enters through the cornea (the transparent front covering) and passes through the pupil, which the iris (colored part) adjusts to control light entry. The lens focuses images by changing shape through accommodation, projecting them onto the retina at the back of the eye.

The retina contains two types of light-sensitive cells: cones and rods. About 6 million cones are concentrated near the center of the retina in the fovea, providing color vision and fine detail in bright light. Approximately 120 million rods are located in the retina's periphery, detecting black, white, and grays in dim light.

After light stimulates these cells, the signals travel through the optic nerve, which exits at the blind spot, where no photoreceptors exist. Inside the eye, the vitreous humor maintains the eyeball's shape and form.

👁️ When you look at something, your visual information travels two possible paths: either to the visual cortex for conscious processing or to the superior colliculus for quick, reflexive responses to movement!

Visual signals cross at the optic chiasm so information from your left visual field goes to your right visual cortex (in the occipital lobe) and vice versa. Some signals also go to the superior colliculus for reflexive responses.

Some people experience color-deficiency (colorblindness), which can be dichromatic (missing one type of cone) or monochromatic (no color vision). In the visual cortex, feature detectors are neurons that respond to specific aspects of what you see, like shapes or movement. Your brain processes multiple aspects of visual information simultaneously through parallel processing.

Visual Perception

Your brain doesn't passively receive visual information - it actively organizes and interprets what you see. The Gestalt psychologists (whose name means "whole" in German) discovered that we naturally integrate pieces of information into meaningful patterns.

Gestalt principles include proximity (we group nearby objects), similarity (we group similar objects), continuity (we perceive smooth, continuous patterns), and closure (we fill in gaps to complete figures). The phi phenomenon explains how we perceive motion in rapid sequences of still images - this is how movies and animation work!

Your ability to perceive depth relies on both binocular cues (using both eyes) and monocular cues (using just one eye). Binocular cues include retinal disparity (the slightly different images your eyes receive) and convergence (how much your eyes turn inward to focus on close objects). Monocular cues include linear perspective (parallel lines appearing to converge), relative size (larger objects seeming closer), and interposition (objects blocking others appearing closer).

🔍 Your brain performs amazing feats of perception constantly! Despite changing conditions, your perceptual constancies let you recognize objects as the same size, shape, and color even when their appearance on your retina changes dramatically.

Other monocular depth cues include light and shadow, texture gradient (textures appearing finer with distance), and height in plane (objects higher in your visual field appearing farther away).

Your brain also maintains perceptual constancies - the ability to recognize objects as the same despite changing sensory input. Color constancy lets you perceive an apple as red whether it's in bright sunlight or shadow. Size constancy allows you to recognize that a person isn't actually shrinking when they walk away from you, and shape constancy helps you identify a door as rectangular even when viewed at an angle.
