Table 1. Predictions of the N400 effect in response to semantic incongruence based on the two mechanisms triggered by mood.

Possible mechanisms	Positive mood	Negative mood
Processing strategy	Rely on information structure: F > NF	Rely on bottom-up input: F = NF
Processing recourses	Sufficient resources for both F and NF: F = NF	Insufficient resources for NF: F > NF

Notes: F: focus; NF: non-focus.
