The eight developmental stages of Graves’ model When encountering external circumstances, people are forced to construct more complex, conceptual models of the environment to help them deal with new problems. Graves passed away in 1986 before he had a chance to publish his work, but it was picked up by Christopher Cowan and Don Edward Beck and published in their 1996 book Spiral Dynamics.īeck then joined forces with Ken Wilbur, a philosopher who popularised spiral dynamics by integrating it into his “theory of everything” framework.įundamentally, spiral dynamics help describe the development of people, organizations, and wider society according to the value systems that motivate them. “ The psychology of the mature human being is an unfolding, emergent, oscillating, spiralling process, marked by progressive subordination of older, lower-order behavior systems to newer, higher order systems as man’s existential problems change.” In truth, however, the spiral dynamics model became far more detailed and insightful.ĭuring his time at North Texas State University, he proposed that: In marketing, the hierarchy (and its basis in psychology) can be used to market to specific groups of people based on their similarly specific needs, desires, and resultant actions. His hierarchy, often depicted in the shape of a pyramid, helped explain his research on basic human needs and desires. Maslow’s Hierarchy of Needs was developed by American psychologist Abraham Maslow. Graves initially sought to validate the work of contemporary Abraham Maslow, who was developing his hierarchy of needs at the time. These values systems he called memes, or sets of world views, preferences, and purposes used to structure societies and integrate the individuals within them. Graves created a psychological model describing multiple stages of human development according to various value systems. Graves. Spiral dynamics is a theory of human development arguing the human mind adapts more complex thinking when faced with similarly complex life experiences. Spiral dynamics is a theory of human evolution based on decades of research by developmental psychologist Clare W.

Use the crop function to zoom in on a point of interestĬhoose Find Equillibrium Point under the Solution pull down menu. If you choose the x-t and y-t option, you have to pick a specific solution curve. If you are interested in a plot of your solution vs. By clicking on the field you will plot solution curves in the phase plane. In the PPlane Phase Plane window below you will see the vector fields for the system.
This is a convenient feature to use when considering the effect of changed parameters on the steady state of a system because it eliminates the redundancy of re-entering the parameter values multiple times within the differential equations. Note, if your differential equations contain constant parameters, you can enter them in the "Parameter Expressions" boxes below the differential equations as seen in the figure below (A, B, and C are used as example parameters). Under the Gallery pull down from the menu, you can switch to a linear system. In the PPlane equation window you can enter a system of differential equations of the form \(dx/dt = f(x,y)\) and \(dy/dt = g(x,y)\), define parameters and resize the display window. We now have a system of equations which we can solve for x, y:
