Abstract
Does the brain represent meaning as fixed categories or graded spaces? Using continuous semantic similarity from distributional models in Picture-Word naming and categorization tasks, ERPs showed task-dependent spatiotemporal effects of target–distractor congruency modulated by their similarity, while RSA captured congruency-dependent graded semantic representations shaped by task demands.
