The present study addresses two objectives regarding motivational and affective variables which affect undergraduate students' learning outcomes. In this investigation, we (1) built an empirical model based on the presage–process–product paradigm to clarify potential effects of study habits and of action–emotion style (a classification resulting from analyses of the components of the Type-A Behavior Pattern) on students' academic performance; and (2) evaluated relations of inter-dependence between levels of TABP components, study habits and undergraduate students' academic performance. We used two different samples of 360 and 409 university students from different programs at a university in southeastern Spain. Findings suggest that action–emotion style is a predictor for explaining students' individual differences in motivation and learning outcomes. The research results of this study, although exploratory in nature, are discussed with respect to implications at the research and practical level.
