Psychology & Mental Health, LIP-PER

Although Sigmund Freud was once one of the most recognizable faces of psychology, this scientific discipline has developed significantly since the time of his predominance. Psychology has become an increasingly integrative science at the hub of diverse other disciplines, from biology and neurology to sociology, anthropology, and economics. At the same time, old sub-disciplinary boundaries within pyschology itself are now crossed more freely; interdisciplinary teams may work on a common problem using methods that draw on multiple levels of analysis, whether social, cognitive, or biological.
