Behaviourism, reductionism and humanism

Behaviourism is at it's core both atomistic and individualistic. Pulling behaviour apart into units such as conditioned and unconditioned stimulus, and the gauging associative responses is an attempt to reduce a complex phenomenon into small parts and thereby is atomistic. It gets further dissected by categorizing conditioning into operant and classical and creating smaller units within each model. Breaking behaviour into units to study it is atomistic in nature, but it is also individualistic because most of the studies involved participants/animals isolated from their environments being manipulated and observed. The findings about the individual are then generalized back to the population, even though they were done looking at a participant in isolation. Many people have criticized behaviourists for this methodological short coming; behaviour undoubtedly has a social component which is herby being ignored.
