pursues the hypothesis that the overarching theory of biology, Darwin's theory, should be the overarching theory of cognitive psychology. David Rosenbaum, a cognitive psychologist and former editor of the proposes that the phenomena of cognitive psychology can be understood as emergent interactions among neural elements that compete and cooperate in a kind of inner jungle. This perspective allows Rosenbaum to present cognitive psychology in a new way, both for students (for whom the book is mainly intended) and for seasoned investigators (who may be looking for a fresh way to approach and understand their material). Rather than depicting the discipline as a rag-tag collection of miscellaneous facts, as has generally been the case in textbooks, this book presents cognitive psychology under a single rubric: "It's a jungle in there." Making continual reference to hypothetical neural creatures eking out their livings in a tough environment, the book offers an over-arching principle that will both entertain readers and motivate more in-depth study of the mind and brain.
