MCAT

This collection is being developed for the revised MCAT® exam that will first be administered in spring 2015. Videos will be added to the collection through fall 2014. All content in this collection has been created under the direction of the Khan Academy and has been reviewed under the direction of the Association of American Medical Colleges (AAMC). All materials are categorized according to the pre-health competencies tested by the MCAT²⁰¹⁵ exam; however, the content in this collection is not intended to prescribe a program of study for the MCAT²⁰¹⁵ exam. The content is also included in the Pre-health Collection within MedEdPORTAL’s iCollaborative sponsored by the AAMC: www.mededportal.org/pre-health *MCAT® is a program of the AAMC and related trademarks owned by the Association include Medical College Admission Test, MCAT, and MCAT²⁰¹⁵.

Community Questions

Biomolecules

Foundational Concept 1: Biomolecules have unique properties that determine how they contribute to the structure and function of cells, and how they participate in the processes necessary to maintain life.

Cells

Foundational Concept 2: Highly-organized assemblies of molecules, cells, and organs interact to carry out the functions of living organisms

Organ systems

Foundational Concept 3: Complex systems of tissues and organs sense the internal and external environments of multicellular organisms, and through integrated functioning, maintain a stable internal environment within an ever-changing external environment.

Physical processes

Foundational Concept 4: Complex living organisms transport materials, sense their environment, process signals, and respond to changes using processes that can be understood in terms of physical principles.

Chemical processes

Foundational Concept 5: The principles that govern chemical interactions and reactions form the basis for a broader understanding of the molecular dynamics of living systems.

Processing the environment

Foundational Concept 6: Biological, psychological, and socio-cultural factors influence the ways that individuals perceive, think about, and react to the world.

Behavior

Foundational Concept 7: Biological, psychological, and socio-cultural factors influence behavior and behavior change.

Individuals and society

Foundational Concept 8: Psychological, socio-cultural, and biological factors influence the way we think about ourselves and others.

Society and culture

Foundational Concept 9: Cultural and social differences influence well-being.

Behavior and genetics

7A: Nature vs. nurture - it’s a dilemma scientists have aimed to answer for years. Do our surroundings or genetics have a greater impact on the individuals we eventually become? You will learn about the way our genes and experiences shape the ways we respond to our environment as we discuss experiments such as twin and adoption studies in the context of development.

Biological basis of behavior: Nervous system

7A: The very fact that you are able to understand this sentence means that neurons in your brain (85 billion in total) are talking to each other. Neurons are the living substance of the nervous system, which extends beyond the brain to the spinal cord and peripherally, allows you to think and process, make decisions, stand up straight, maintain your heart rate, rest and digest. You will come to appreciate the structure and function of the nervous system as we delve into its anatomy and physiology, from the gray and white matter to the cerebellum to the neurons.

Biological basis of behavior: Endocrine system

7A: Glands are special organs that secrete chemical messages called hormones, which seep into the blood - it’s like putting a tea bag in hot water. As the heart pumps, this blood carries these chemical messages throughout the body, allowing the hormones to interact with specific target cells and organs. Not only do these hormones play a role in maintaining our appetites and concentrating urine, but they also have a huge impact on how we behave. In this module we will examine how these variegated hormones play a role in influencing human behavior, growth, and development.

Theories of personality

7A: Curious about your personality? It’s a complex thing which is difficult to define in even a book. Nonetheless, throughout history, several notable psychologists and schools of thought have attempted to figure out how to organize and categorize human personalities. We will review these theories and see which one resonates the most with you! By Shreena Desai. Motivation and attitudes - What makes us dot he things we do, or feel the way we feel in various social situations? We will discuss how the physiological and psycho-social theories, factors, and situations behind motivation, attitudes, and behavior are interrelated.

Social psychology

Birds of a feather flock together. How do we explain these and other observations in the way we interact with fellow human beings? We will dive into the fascinating and relevant world of social psychology as we discuss concepts which you may have noticed in real life. You will come to know the names of such phenomena as well as the specific factors that motivate people to behave the way they do in groups.

Normative and non-normative behavior

7B: Learn about how "normal" and "deviant" behavior is defined in today's society. This includes a discussion of the range of normal and abnormal behavior, common theories used to understand basic deviance, and discussion of some types of deviance that occur in groups.

Learning

7C: This is the most “meta” of all modules, in which you will learn about learning! Your environment has a huge impact on your future behavior, and your behavior itself has consequences on the environment. You will come to appreciate the mechanisms of classical and operant conditioning (and how you can apply these concepts to training your dog!). We will apply these to contemporary issues like the issue of violence in the media. As you go through this module, you will gain an understanding of how your brain retains new information.
