In this episode of Beyond Words, Garrett Oyama speaks with Dr. Sam Wass, developmental neuroscientist, about how attention, arousal, and social interaction shape the developing brain.

They explore how infants regulate attention in real time, how stress and environmental context influence learning, and what brain-to-brain synchrony between parents and children reveals about communication. They discuss neural entrainment, shared book reading, and the role of co-regulation in supporting language development. Along the way, they connect laboratory neuroscience to everyday parenting and clinical practice, reframing language learning as something deeply embedded in attention, physiology, and relationships.

In this episode of Beyond Words, Garrett Oyama speaks with Dr. Joan Bybee, pioneer of usage-based linguistics, about how language emerges through use, repetition, and social interaction rather than abstract rules.

They explore why sounds don’t exist in isolation, how frequency and predictability shape speech and sound change, and what this means for child language development, speech therapy, and learning. Along the way, they connect language to music, motor practice, and improvisation, reframing speech as a dynamic, living skill shaped by experience.

Topics include:

• Why language and thought are separate systems
• How ChatGPT challenges our assumptions
• What Broca’s area really does
• Implications for speech therapy and assessment
• What LLMs and infants both tell us about language learning

What does it mean to hear the world through two languages? In this episode, host Garrett Oyama speaks with Dr. Jenn Krizman, research scientist at the Brainvolts Lab (Northwestern University), about how bilingualism reshapes the brain’s sound processing networks.

Together they explore how speaking multiple languages enhances inhibitory control, boosts consistency in auditory encoding, and even provides a kind of “neural armor” that can delay cognitive decline. They also discuss clinical implications for speech-language pathologists, common myths about bilingualism, and why parents should feel confident nurturing their child’s native tongue.

In this special archive episode, Garrett sits down with fellow UCLA PhD student Constance (Connie) Bainbridge, a researcher in the Department of Communication who studies the inner voice—how we communicate with ourselves. Connie is the Principal Investigator of the Stream of Mind Lab and her work blends evolutionary, developmental, and cognitive science to better understand intrapersonal communication and the flow of consciousness. She also draws on her background as a musician to explore how music and self-expression shape human experience.

This conversation covers:

• What the “inner voice” really is
• How self-talk and imagination shape decision-making, self-regulation, and well-being
• Why hidden differences (like having no inner voice) matter for research and therapy
• Connections between music, language, and consciousness

Dr. Kraus shares her journey from studying chinchilla neurons to developing clinically relevant tools for measuring how the human brain processes sound. Together, they explore the frequency following response (FFR), the role of music in therapy, and why understanding the brain’s sound processing is essential for clinicians, educators, and anyone working with language.

This episode laid the foundation for an ongoing series of conversations between Garrett and Dr. Kraus, diving deeper into the science and clinical applications of Of Sound Mind. Find them here:

In this episode, neuroscientist Dr. Charan Ranganath (author of Why We Remember) joins Garrett Oyama to explore how schemas, event boundaries, and the structure of language shape what we remember — and why. We discuss how memory works not just in the brain, but in real life: through storytelling, attention, emotion, and meaning. SLPs, therapists, and educators will also gain practical tools for supporting memory using language — from narrative scaffolds to emotional salience and linguistic cues that enhance recall.

Topics include:

• How the brain chunks experience into events
• Why schemas help (and sometimes distort) memory
• The blurred line between cognition and memory
• How to use language to support clients with memory difficulties
• Memory as prediction, not just storage

Dr. Ev Fedorenko (MIT) joins host Garrett Oyama to explore how the brain processes language — and why the language network is far more distinct and specialized than previously thought. From the surprising isolation of this network to what this means for aphasia, speech therapy, and AI, this episode dives into some of the most exciting neuroscience of language today.

We discuss:

• Why traditional brain maps may be misleading
• How individual brain variability affects language recovery
• Why the language system doesn’t overlap with math, music, or logic
• What this means for clinicians and educators

Best known for her TED-Ed video How Playing an Instrument Benefits Your Brain, Dr. Collins brings science down to earth, showing how sound acts as “superfood” for a baby’s brain and how music learning can profoundly shape language, attention, literacy, and even emotional regulation.

Whether you’re a parent, speech-language pathologist, educator, or simply music-curious, this episode is packed with insights and real-life strategies:

🎶 Why singing to your baby is more powerful than playing music on a device

🧠 How rhythm and beat perception relate to reading ability

🗣️ The surprising connection between musical training and speech development

👶 What to know about noisy environments and infant sound nutrition

💡 Easy musical activities that support language — even if you “can’t sing”

Join host Garrett Oyama in this thought-provoking episode of Beyond Words, featuring Dr. Elan Barenholtz, cognitive scientist and professor of psychology at Florida Atlantic University. Together, they explore Dr. Barenholtz’s compelling theory that language is not invented, but discovered—emerging from structured, sequential patterns much like music. They dive deep into the concept of language as an autoregressive system, where meaning arises not from static symbols but from dynamic movement through linguistic space. Key topics include the aesthetics of syntax, the parallels between language and jazz improvisation, and what large language models can teach us about human communication. With implications for AI, language development, and clinical practice, this episode offers a paradigm-shifting view of how we speak, think, and understand the world.

Description:

What shapes the way humans speak? In this episode of Beyond Words, Garrett Oyama sits down with Dr. Ted Gibson, professor of cognitive science at MIT and director of the MIT Language Lab, to explore how language emerges from cognitive and communicative pressures.

From Amazonian hunter-gatherer languages with no number words, to cross-linguistic patterns explained by dependency length minimization, Ted shares insights from decades of research across dozens of languages. We also discuss why syntax matters for communication, how brain imaging separates language from thought, and what this means for speech-language pathologists, educators, and anyone fascinated by human cognition.

What does it take to make sense of the sound soup that surrounds a newborn? In this episode of Beyond Words, Garrett Oyama sits down with Dr. Jenny Saffran—pioneer of infant statistical learning—to explore how babies transform streams of speech into meaningful language, all without seeing “white spaces” between words.

Together, they dive into:

• How infants use statistical learning to segment and group sounds
• Why the brain’s ability to track syllable patterns is like a built-in prediction engine
• How context and the physical environment (like shape-sorter toys!) support early word learning
• New work applying eye-tracking to understand language in children with cerebral palsy
• The intersection of music, language, and domain-general learning mechanisms

Dr. Saffran also weighs in on nature vs. nurture, the rise of large language models, and why infants may be motivated not by communication—but by the desire to grip the world with meaning.

Whether you’re a speech therapist, a cognitive science fan, or just fascinated by how humans learn to speak, this conversation opens up wonder and insight on every level.
