Q

Ways of building a nomological net

A

Direct Effects:
Main Effect: ex. H1. control variable (Reflection) influences outcome variable (performance outcomes).

Indirect Effects:
Moderation: One variable that augments or diminishes the main effect. (valence of past experience)
Mediation: Intermediary variable between control and outcome variable (perceived self-efficacy).
