The model views different cognitive behaviors as caused by three different entities instead of one. The reptilian complex is said to control all of the instinctual and impulsive actions, while the neomammalian complex is responsible for keeping the primitive instincts constrained. An example is controlling the impulse of eating.
MacLean was an American physician and neuroscientist who formulated his model in the 1960s, which was published in his own 1990 book The Triune Brain in Evolution. [1] MacLean's three-part theory explores how the human brain has evolved from ancestors over millions of years, consisting of the reptilian , paleomammalian and neomammalian complexes .
The theory of Michael Commons' model of hierarchical complexity is also relevant. The description of stages in these theories is more elaborate and focuses on underlying mechanisms of information processing rather than on reasoning as such. In fact, development in information processing capacity is invoked to explain the development of reasoning.
Theory of multiple intelligences – Educational model of human intelligence; Transtheoretical model, also known as Stages of change – Integrative theory of therapy; Zone of proximal development – Difference between what a learner can do without help and what they can do with help
Human development theory is a theory which uses ideas from different origins, such as ecology, sustainable development, feminism and welfare economics. It wants to avoid normative politics and is focused on how social capital and instructional capital can be deployed to optimize the overall value of human capital in an economy.
Also, members of older groups tended to perceive their groups to have more of the characteristics of Stage-3 and Stage-4 groups and to be more productive. Based on these results, Wheelan's position supports the traditional linear models of group development and casts doubt on the cyclic models and Gersick's punctuated equilibrium model.
The commonly accepted theory for the evolution of plant morphology is the antithetic theory. The antithetic theory states that the multiple mitotic divisions that take place before meiosis, cause the development of the sporophyte. Then the sporophyte will development as an independent organism. [43]
In this model, child development into adolescence and adulthood can be explained either by intrinsic aspects of the child or by extrinsic factors influencing the child. [ 6 ] Probabilistic epigenesis draws from this model in that it emphasizes the importance of factors that could be categorized as nature and/or nurture. [ 7 ]
