Hi spmers,
Is the Parametric Modulations in the 1st_level analysis a kind of moderating effect/interaction effect analysis? That mean the 【Parameter】 I set in Parametric Modulations is a moderator?
Or this is a kind of covariate analysis?
I found that the condition(regressor) effect after setting up a 【Parameter】seems has covaried out the "modulation effect" of that 【Parameter】, it is more likely to be a covariate analysis. But the global covariates are set up in the Regressors session, so I am confusing about this Parametric Modulations analysis.
I hope someone can help me out!
Thank you very much!
