A new study has found that learning new words can stimulate the brain’s reward circuits, particularly the ventral striatum, a region responsible for pleasure and motivation.
This discovery doesn’t just explain why book lovers get a thrill from discovering new vocabulary—it also raises profound questions about how language evolved in humans.
Could it be that our love for words is not just intellectual, but deeply biological?
The Science Behind the Joy of Language
An international team of neuroscientists set out to understand the connection between language and pleasure.
Their research, published in Current Biology, involved 36 participants who were tested in two scenarios:
- A gambling simulation, designed to trigger classic reward responses.
- A language-learning exercise, where they were taught new words.
While undergoing these activities, the participants had their brain activity monitored using functional magnetic resonance imaging (fMRI).
What they found was striking:
- Learning new words didn’t just activate the cortical language centers of the brain.
- It also lit up the ventral striatum, the same pleasure-related brain region stimulated by food, sex, gambling, and drugs.
This suggests that language learning is not just a cognitive process—it’s an inherently pleasurable one.
“The aim of the study was to find out to what extent learning a language could activate these pleasure and reward circuits,” explained lead researcher Antoni Rodríguez Fornells, a biologist from the University of Barcelona.
And the implications go beyond mere curiosity.
If language-learning is biologically rewarding, it could help explain why humans developed complex language in the first place.
But Wait—Isn’t Language Just About Logic and Rules?
For years, scientists have assumed that language evolved through structured learning, repetition, and cognitive reasoning.
The idea that emotion and pleasure play a central role in language acquisition challenges this traditional perspective.
Think about it:
- We remember words better when they make us feel something—whether it’s a funny slang term, a poetic phrase, or a powerful insult.
- Children learn language more effectively through playful and emotional interactions rather than strict memorization.
- Even as adults, we’re more likely to retain vocabulary that is connected to personal experiences or strong emotions.
This study reinforces a new way of thinking: that our love for language is deeply tied to pleasure and reward—not just logic.
“The study questions whether language only comes from cortical evolution or structured mechanisms and suggests that emotions may influence language acquisition processes,” Fornells explained in a press release.
So, if words trigger the same circuits as sex, chocolate, and gambling, could our linguistic abilities have evolved because they were inherently pleasurable?
Why Some People Learn Faster
Another fascinating discovery from the study was that not everyone experiences language-learning in the same way.
Researchers found that participants who had stronger neural connections between the brain’s language centers and the ventral striatum were able to learn new words more easily than others.
In other words:
- If your brain has a tighter link between pleasure and language, you’ll likely pick up new words faster and retain them longer.
- This might explain why some people seem naturally gifted at learning languages, while others struggle.
It also raises a tantalizing question:
Could we train the brain to associate language with greater pleasure, making it easier to learn?
This idea could have major implications for language education, suggesting that making vocabulary-learning enjoyable isn’t just a preference—it’s a necessity for success.
How to Hack Your Brain for Better Language Learning
If language-learning is tied to pleasure, then the key to mastering new words isn’t brute-force memorization—it’s making the process enjoyable.
1. Engage Emotionally with New Words
- Read stories or listen to music in the language you’re learning.
- Attach personal meaning to new words—use them in funny, surprising, or emotional contexts.
- Play word association games to trigger deeper connections in your brain.
2. Use the “Reward System” to Your Advantage
- Set up a reward-based learning system—treat yourself after mastering new vocabulary.
- Turn language-learning into a game (apps like Duolingo and Memrise do this well).
- Surround yourself with native speakers or engaging content—social interaction adds a pleasurable reward to language use.
3. Learn Like a Child: Through Play and Repetition
- Children learn best when they’re playing, laughing, and interacting with their environment—adults can tap into this same power.
- Instead of rigid grammar drills, try storytelling, humor, and creative writing.
By aligning language-learning with the brain’s natural pleasure system, you can boost retention, enjoy the process, and learn faster.
Could This Explain How Language Evolved?
Scientists have long wondered why humans developed complex language while other animals did not.
One theory is that language evolved because it was useful for survival—allowing humans to communicate, cooperate, and share knowledge.
But this new research suggests another factor might have played a role:
- What if language evolved not just for survival, but because it felt good?
- If early humans experienced pleasure when learning and using language, they may have been naturally motivated to develop more words, expressions, and linguistic complexity.
This could mean that language is not just a tool—it’s a reward in itself.
Why This Matters for You
If you’ve ever felt that learning a new language is frustrating, this research offers a new way of thinking:
- You’re not just memorizing words—you’re engaging in an activity that your brain is wired to enjoy.
- The more pleasure you associate with language, the easier and more natural it will become.
So, the next time you come across an interesting new word, take a moment to appreciate the rush of pleasure that comes with understanding it.
Because language isn’t just about communication—it’s about joy, discovery, and the sheer thrill of learning.
And if expanding your vocabulary can trigger the same circuits as sex, chocolate, and gambling?
Well, that’s just one more reason to pick up a book, do a crossword, or start learning a new language today.
