The study aims at investigating students' learning/defence profiles. It also explores students' profiles during different years of study. Participants comprised of 425 undergraduates. They completed the 'Approaches to Study and Skills Inventory' and the 'Defense Style Questionnaire'. The students' academic achievement was measured through grade point average. Cluster analysis revealed three profiles: 'restricted maturity and dissonant-unorganized' students, 'defensive and reproduction oriented' students, and 'mature and learning advanced' students. The profiles correspond to adaptive and maladaptive learning patterns. The study also revealed few (a) differences across the years of study (on strategic approach) and (b) interactions between the three clusters and the years of study (on mature defence style and GPA). The findings are discussed in relation to recent literature. Limitations and future research suggestions are presented.
