Stages of Development
The following grids try to help in understanding how our behaviors develop. The grid represents the four interrelated parts of an individual. The left half identifies mental-emotional aspects of life and the right half identifies the physical. Similarly, the top half represents the individual side of life, while the bottom suggests the group.
Existence is the first assumption we can make regarding behavioral development. Upon conception, we become part of our environment, society and economy.
Existence Matrix | Mental/emotional (mind) the intangible, qualitative side of life | Physical (body) the tangible, quantitative side of life |
Individual | not formed yet - to be shaped through developmental process | • physiological structure and capability • physics, chemistry, biology,anatomy (sensory receptors),genetics, neuroplasticity |
Group | • culture • social norms • mores • ethics • values • constantly changing with individuals interacting in their environment • sociology, anthropology, philosophy | • environmental structure and capability • economic structure and capability • ecology, economics, systems theory |
A short while after conception, in utero, experiences begin to leave their impressions. Experience is the next rung up our developmental ladder. As you can see, with experience the individual begins to form a mental-emotional framework in which their unique thoughts and feelings begin to form their personality.
Experience Matrix | Mental/emotional (mind) the intangible, qualitative side of life | Physical (body) the tangible, quantitative side of life |
Individual | • internal model (perception) of reality • constantly changing (new information, new experiences = new perceptions) • unique perception based on one's culture, education, gender, age, physiology, etc. • highly subjective • frequently inaccurate • philosophy, psychology, meditation | same as above |
Group | same as above | same as above |
