(A) represents a model resembling the path model in Fig.1 excluding the two insignificant effects. (B) represents a version of model A in which the roles of “valuation” and “self-related processing” are switched. (C) represents a version of model A in which the roles of “valuation” and “social cognition” are switched. AIC, Akaike’s information criterion; BIC, Bayesian information criterion.
