The present study addresses two objectives regarding motivational and affective variables which affect under-graduate students' learning outcomes. In this investigation, we (1) built an empirical model based on thepresage–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 and409 university students from different programs at a university in southeastern Spain. Findings suggest thataction–emotion style is a predictor for explaining students' individual differences in motivation and learningoutcomes. The research results of this study, although exploratory in nature, are discussed with respect toimplications at the research and practical level
