Table 4. Language processes isolated by subtraction of different baseline tasks from semantic decision.
Table shows comparison of active and passive baseline tasks as used for subtraction with semantic decision, in terms of the language and domain-general processes engaged by each paradigm and isolated by the subtraction contrast.
