The decade of the 1960s witnessed early attempts to create a unified
science-profession of clinical psychology. Following in the path of
these efforts - and the behavioral revolution in clinical psychology,
which occurred around the same time - Donald Peterson set out to write
what he describes in his new introduction as a "manifesto" for a
"scientifically grounded, practically effective professional
psychology." Originally published by Appleton-Century-Crofts in 1968.
