Summary of the results.

	Findings
Behavioural	Percentage of impulsive choices changed from 61.43 when an immediate reward was present (immediacy present) to 28.49 when both rewards were delayed (immediacy absent)
ERP	Larger P2, LPP and smaller N2 in response to immediacy
Source Analysis	Increased activation of lingual, fusiform, superior temporal, and postcentral gyri during P2 in response to immediacy
	Increased activation of lingual gyrus and decreased activation of middle temporal gyrus during N2 in response to immediacy
	Increased activation of lingual and fusiform gyri and cuneus during LPP in response to immediacy
Correlational	During P2, differential activation of insula between the immediacy conditions predicted individual differences in degree of preference reversal
