The science behind Lexy
We don't believe in secret proprietary methods or magic pills. The architecture of every 5-minute Lexy lesson rests on forty years of foundational research into memory and applied linguistics.
The production effect: why words stick only when you say them out loud
A reading of Professor Colin MacLeod's eight experiments: why saying a word aloud leaves a triple sensorimotor trace that silent reading cannot match.
The testing effect: why active recall beats rereading three times over
The Washington University experiment: why rereading your notes creates an illusion of knowing, while an unaided test holds 80% of the material a week later.
The output hypothesis: why passive listening never teaches you to speak
Canada's immersion-school research: why understanding runs on guesswork (semantics) while your own speech forces you to assemble grammar (syntax).
Language anxiety: why correcting errors on the fly shuts speech down
The FLCAS scale and the affective filter: how fear of a teacher's judgement suppresses Broca's area, and why Lexy deliberately stays quiet for the first 15 lessons.
Distributed practice: why a 25-minute lesson beats a two-hour cram
A synthesis of 317 experiments over a century: synaptic consolidation during sleep, and why 16 short lessons reach what weekend cramming cannot.
Spaced learning in a second language: a meta-analysis of 48 studies
3,411 participants in Language Learning: an effect size of g = 0.81 for vocabulary and grammar when the intervals expand.
Broca’s and Wernicke’s areas: how the brain actually learns a language
Why the two-box model is retired, how the adult brain builds dedicated circuits for a second language, and what HD-tDCS and fMRI experiments reveal.
Put the science to the test
In Lexy the first two lessons of any of the 37 languages are free. The first one opens with no sign-up: press the button, allow the microphone and start speaking right now. No bank card needed.
