This eight-volume set brings together two four-volume sets to cover both the classic and contemporary reading in theoretical psychology. "Theoretical Psychology: Classic Readings": Covering foundational works in theoretical psychology up to 1980, this four-volume collection is an authoritative and groundbreaking survey of the early theoretical foundations of modern psychology. Edited and introduced by a leading authority in the field, this selection tells the story of the early crises and debates that forged each major branch of psychology, from functionalism to clinical psychology. The volumes include: "Volume One: The Origins of a Theoretical Psychology"; "Volume Two: Theory and Method"; "Volume Three: Major Theoretical Positions in 20th Century Psychology"; and, "Volume Four: The Human Dilemma: Social, Developmental and Abnormal Psychology"."Theoretical Psychology: Contemporary Readings": This four-volume collection picks up the story of theoretical psychology in the 1980s, as it becomes a legitimate form of enquiry in its own right, and follows it as it develops through alternative and critical streams into the newfound fields of 21st century psychology, like situated cognition, embodied cognition and extended mind theory. This collection can serve as the last word on modern theoretical psychology in its own right, or as a companion to "Theoretical Psychology: Classical Readings". The volumes include: "Volume One: Contemporary Theoretical Psychology"; "Volume Two: Theory and Method"; "Volume Three: Cognitive Psychology, Cognition, Embodied Cognition"; and, "Volume Four: Contemporary Human Social, Developmental and Abnormal Psychology".
