Welcome back to the Jack Westin MCAT Podcast with Mike and Molly! Last episode we broke down the neurobiology of language; Broca's, Wernicke's, split-brain patients. This episode we zoom all the way out and ask a question that's fascinated scientists for centuries:

Does the language you speak actually shape the way you think?

This is one of the most debated topics in MCAT psychology and one of the most fascinating. Mike and Molly break it all down, name by name, theory by theory.

📊 High-yield MCAT visual: Picture a number line. Thought on the left, language on the right. Every theory in this episode falls somewhere on that line — and knowing where is everything.

🔑 Names you MUST know for the MCAT:

Chomsky · Skinner · Vygotsky · Piaget · Sapir-Whorf

🎧 Next episode: Biomolecules — amino acids, proteins, enzymes, and DNA. The highest-yield topic on the entire MCAT. Don't miss it.
