This book is addressed to all students who want to deepen, for various reasons, the field of psychology. It was written with the idea to help both those who are preparing for the baccalaureate exam, and those who will take examinations in this subject to admission to college. From difficulties understanding this discipline by pupils, difficulties which I faced in teaching, I wrote this book to help students eliminate possible confusion or misleading information you may have in this area. Those who browse this collection, have the chance to enrich informational content and also to clarify and better understand the concepts of psychology. And if the way to the "realm of psychology" will be less difficult and because of this book, this will be the living proof that this collection "asked to be written!"
