Paradigmatic or psychological behaviorism (PB), in a four-decade histo
ry of development, has been shaped by its goal, the establishment of a
behaviorism that can also serve as the approach in psychology (Watson
's original goal). In the process, PB has become a new generation of b
ehaviorism with abundant heuristic avenues for development in theory,
philosophy, methodology, and research. Psychology has resources, purvi
ew and problem areas, and nascent developments of many kinds, gathered
in chaotic diversity, needing unification (and other things) that cog
nitivism cannot provide. Behaviorism can, within PB's multilevel frame
work for connecting and advancing both psychology and behaviorism.
