This open access textbook was developed as an upper division undergraduate textbook for theories of personality. Its intended audience are students from Portland State University enrolled in Psychology 432 Personality course. The chapters are shorter than some personality textbooks and in this particular course Psy 432 the textbook is combined with other readings including scientific articles on personality. This open access textbook may be of interest to other courses interested in teaching about theory and research on personality.
This textbook provides a toolbox, a guidebook, and an instruction manual for researchers and interventionists who want to conceptualize and study applied problems from a developmental systems perspective, and for those who want to teach their graduate (or advanced undergraduate) students how to do this. It is designed to be useful to practitioners who focus on applied developmental problems, such as improving the important developmental contexts where people live, learn, and work, including the applied professions in education, social work, counseling, health care, community development, and business, all of which at their core are concerned with optimizing the development of their students, clients, patients, workers, citizens, and others whose lives they touch.
