Interaction effects in factorial design refer to the situation where the effect of one independent variable on the dependent variable depends on the level of another independent variable. It is possible to hypothesize such interactions without predicting differences for any of the main effects, meaning that even if the independent variables do not have a significant individual impact on the dependent variable, they might still interact in a way that influences the dependent variable when combined.
