Psychology is becoming an increasingly specialized but fragmented field. Forces within psychology and society at-large have tended to push psychologists apart. It will take a concerted belief in the importance of unity to combat these forces and mend psychology's splintering image. Unity in Psychology: Possibility or Pipedream? examines the opportunities for psychologists to come together and unify. A distinguished group of contributors share their common belief that, at some level, the fragmentation of psychology is a mistake.

Unity in Psychology: Possibility or Pipedream? will provoke psychologists to examine the forces that define the field and take an active role in shaping the future.
