Table A2.

Study variables according to strategy.

Strategy	Independent variable	Dependent variable	Contrast of interest
A1. Real-time MW sampling	State (task vs. rest)	Behavioral measures	Rest vs. task
A2. Retrospective evaluation of MW	State (task vs. rest)	Behavioral measures	Rest vs. self
B1. Parametric modulation of self-relatedness	Degree of self-relatedness	Degree of neural activation	Self-related vs. non-self-related task
B2. Parametric modulation of cognitive load	Degree of cognitive load	Degree of neural activation	Rest vs. task
B3. Paradigm-free analysis of neuronal dynamics	State of consciousness	Degree of functional connectivity	Conscious state x vs. conscious state y

This table summarizes typical independent and dependent variables, as well as contrast of interest (relevant to neuroimaging analysis) in each of the five strategies.
