Through their own research and clinical work, as well as their experiences as teachers, highly regarded authors Stephen Kosslyn and Robin Rosenberg have found that exploring psychology from multiple perspectives further enhances learning. Psychology: The Brain, The Person, The World, Second Edition examines psychological concepts from the levels of the brain (biological factors), the person (beliefs, desires, and feelings) and the world (social, cultural, and environmental factors) and their interactions, in order to help students organize and integrate topics within and across chapters and actively apply psychology to their lives.
