In contemporary psychology three worldviews can be recognized, of which each seems focused on a particular type of behaviors or processes: Behaviorism, psycho analysis, and cognitive psychology. Each of these worldviews can be perceived as a different brain system. Are the systems related?
The whole can be perceived as a reflection (or a perception filter) of the Triune brain.
To begin with, the distinctions seem fuzzy and many psychologists seem rather eclectic to me. A single worldview can monopolize us. Monopolization may mean certain behaviors or processes are considered more important than others.
One might consider monopolization a "bad thing". Amazingly, instead of causing "war" and "conflicts of opinion", this monopolization seems to keep psychologists out of each others hair. Psycho analysists appear to consider feelings more important than rational processes, the field cognitive psychology seems to mostly focus on. And while cognitive psychologists do not seem to care much for emotions and conditioned responses, the behaviorists appear to find a smorgasbord of attractions in those "things". There seem to be no really disruptive arguments in this configuration. Each of the three worldviews is trying, in her own way, in her own field, to make meaning of as much behavior and/or psychic processes with as little axioms and laws as possible: Maximum Results with Minimum Effort.
By combining the three worldviews, a small number of patterns can be enough to explain a multitude of processes and we have a larger hand to play with as facilitators.
And what about this for multiple perspectives and easy integration?
According to Professor Howard Gardner of Harvard University, there are at least eight different kinds of human intelligence. Individuals would possess these eight intelligences to varying extents. The first seven intelligences were addressed in Gardner's book "Frames of Mind: The Theory of Multiple Intelligences".
Recognition of our strengths and weaknesses in the different intelligences impinges directly on our ability to generate creative outcomes in various domains: Ten Intelligences.
