Moderated-Mediation Models								p	v

Notes: The models refer to either the simple mediation model, Fig. 2A, or the moderated-mediation model, Fig. 2B. BcB CI: bias-corrected bootstrap confidence interval for the indirect effect in the mediation models, and for the conditional indirect effect in the moderated-mediation models. Brain: refers to mean functional brain activity in the entorhinal cortex. All models covary for sex. Models which include brain activity additionally covary for mean paced respiration adherence.
