EEG foundation models are outperformed by task-specific models on a new rigorous 4-letter handwriting decoding task from EEG, with performance dropping without movement-onset knowledge and improving more from better test-time signals than from scaling data.

Handwriting decoding as a challenging motor task for EEG Foundation Models
EEG foundation models are outperformed by task-specific models on a new rigorous 4-letter handwriting decoding task from EEG, with performance dropping without movement-onset knowledge and improving more from better test-time signals than from scaling data.
