What is the MCAT Psychology and Sociology Section?
The MCAT Psychology and Sociology section is a common shorthand term for the Psychological, Social, and Biological Foundations of Behavior section – one of the four scored sections of the MCAT. Its 59 questions assess your ability to draw on concepts from psychology, sociology, and behavioral science during your analysis of passage-based research and data to demonstrate scientific reasoning skills.
The content covered in this section can be broken down as follows:
Questions in this section incorporate common concepts taught in introductory psychology and sociology courses. For many premeds who may be from a strictly STEM background, this section can present a unique challenge as you’ll need to use discrete concepts to unfamiliar scenarios, interpret research findings while evaluating data within passages.
As BeMo admissions expert Dr. Cathleen Kuo, MD, explains:
"The most challenging aspect of this MCAT section for me was dealing with the dense and lengthy passages, reminiscent of the CARS section. Additionally, encountering unfamiliar topics that were not covered in my studies posed a significant hurdle." – Dr. Cathleen Kuo, MD
What Topics are Tested on the MCAT Psychology and Sociology Section?
The Association of American Medical Colleges (AAMC) organizes the MCAT Psychology and Sociology Section around five foundational concepts that bring together related psychology, sociology, and behavioral science topics. These foundational concepts encompass topics ranging from perception and learning to social behavior, cultural influences, and health disparities.
If you’d like a more detailed overview of the high-yield topics within each foundational concept, explore our guide to high-yield MCAT topics alongside AAMC’s official content outline.
Quick BeMo Tip
After you’ve identified the foundational concepts you’ll need to cover, build an MCAT study schedule that addresses your strengths and weaknesses and aligns with your planned MCAT test date.
One approach that worked well for BeMo admissions expert Dr. Cathleen Kuo, MD, was researching the context behind each concept:
"I delved deeper into the topics by researching the stories behind each name and concept. This helped me connect with the material on a deeper level, and I found it easier to retain information after understanding the context and history behind [it]." – Dr. Cathleen Kuo, MD.
Tips for Acing the MCAT Psychology and Sociology Section
A high score on the MCAT psychology and sociology section goes beyond content knowledge. Understanding of how section questions are designed, recognizing what they're assessing, and putting concepts into practice under exam conditions are equally important to your success.
The following strategies can help you prepare more effectively for test day.
Tip #1: Understand the Skills Being Tested
The MCAT psychology and sociology section assesses far more than your ability to recall definitions. Every question is designed to evaluate one or more scientific reasoning skills that the AAMC uses across all four sections of the exam.
Recognizing which skill a question is testing allows you to choose an effective approach instead of solely relying on memorization.
Each skill requires a different approach. A terminology-based question, for instance, may rely on concept recall while a research question depends on how you evaluate the methodology within a scientific passage before considering the answer options.
Developing strong MCAT reading comprehension skills can also improve your performance on this section. Reflecting on her own preparation for the section, Dr. Cathleen Kuo, MD, found that practicing CARS passages strengthened her ability to identify key information in dense passages:
"I focused on practicing CARS passages to enhance my reading comprehension skills and ability to extract key information from dense texts. This approach helped me navigate through lengthy passages and extract relevant information efficiently, improving my overall performance in the section." – Dr. Cathleen Kuo, MD.
Tip #2: Know Your Psychology and Sociology Terminology
Psychology and sociology terminology appears throughout the section. While you’ll need to recognize common terms quickly, you’ll also need to distinguish between related concepts to determine which best explains the scenario presented.
If you encounter unfamiliar terminology on test day:
- Use the surrounding passage to infer the meaning of the term
- Eliminate answer choices that conflict with the evidence presented
- Focus on the concept that best explains the scenario instead of searching for a perfect keyword match
BeMo admissions expert, Dr. Noah Heichel, DO, found that regularly reviewing terminology with flashcards improved his section score:
“Flashcards helped me jump almost 3 points in my [psych/soc] section, even in the week before the exam. This was my weakest subject, but it was my highest score on my exam.” – Noah Heichel, DO
Tip #3: Analyze Research and Data Systematically
Many psychology and sociology questions rely on how you interpret research studies, experiments, and data. If interpreting visual data is challenging, learning how to read MCAT graphs can help you to efficiently evaluate figures and experimental results.
Before selecting an answer, ask yourself:
- What question is the study investigating?
- Which variable is being manipulated?
- Which outcome is being measured?
- What conclusion is supported by the data?
- Which answer choice is supported by the evidence?
Working through practical examples can make psychology and sociology concepts easier to understand and recall. As BeMo admissions expert Dr. Neel Mistry, MD, explains:
“Thinking practically and applying learned concepts to real-life examples [or] reading up on how different psychological/sociological concepts came to be [helped me]. This was interesting and made it easier to remember the information in a laid-back manner.” – Dr. Neel Mistry, MD

Sample MCAT Psychology and Sociology Questions and Answers
The following sample MCAT Psychology and Sociology passage is adapted from official AAMC practice materials and reflects the style of questions you'll encounter on the MCAT. Complete the passage before reviewing BeMo expert explanations to better simulate exam conditions.
Sample MCAT Psychology and Sociology Passage
The illness experience shapes the way that people use health information. For patients with a rare health disorder, which is defined as a medical condition that affects fewer than 200,000 individuals living in the United States, online sources of information tend to be particularly important.
An example of a rare disorder is Amyotrophic Lateral Sclerosis (ALS), also known as “Lou Gehrig’s disease.” ALS results from the progressive loss of motor nerves and affects about 1 out of 100,000 people. About 10% of people with ALS have a familial form of the condition, which is caused by an inherited genetic mutation. Aside from the familial form, the cause of ALS is largely unknown, though it is believed that the disorder results from both genetic and environmental factors.
Having a rare medical condition, such as ALS, can make it difficult to meet and interact with others who have the same rare disorder. Despite great distances, online communication provides a form of social interaction for those facing an uncommon health problem. Virtual peer networks provide vital social support for those who are affected by a rare disorder.
Research has found that women with rare disorders are more likely to access online support networks than men with rare disorders. Relationships formed through online support networks often become a meaningful part of a person’s identity. Individuals with rare disorders report that relating to others who have the same condition is often easier than trying to relate to friends or family members who do not share their condition.
Sample MCAT Psychology and Sociology Questions and Answers
1. Which statement best represents a threat to social identity? A young woman with a rare disorder:
A) believes that others treat her as less capable, and then she starts to see herself as deficient.
B) becomes discouraged when she hears that others with rare disorders are treated as less capable.
C) hides her disorder from others in order to project more confidence in social situations.
D) reveals her disorder to friends, who mistakenly assume that it is a social limitation.
2. Over the course of ten years, a rare disorder increases in prevalence such that it eventually affects more than 200,000 people in the United States. Based on the passage and this scenario, which prediction is most consistent with the sociological paradigm of symbolic interactionism?
A) As the number of affected individuals increases, government research funding increases.
B) Affected individuals are less likely to conceal their condition as it becomes less stigmatized.
C) As more people with the condition are treated, it receives less attention as a health concern.
D) Insurance coverage for the condition becomes more likely as more people require treatment.
3. Which research project best represents a macrosociological approach to studying the social support networks mentioned in the passage?
A) A researcher follows the conversation of participants who post messages in an online support forum.
B) A researcher interviews patients who participate in a local hospital’s support group for rare disorders.
C) A researcher surveys patients for reasons that they joined an online support group for their disorder.
D) A researcher tracks how the number of websites dedicated to rare disorders has changed over time.
