The core idea here is that developmental progressions—whether physical, cognitive, or epistemological—emerge through the integration of simpler elements into increasingly complex structures. This process is observable across various domains, from motor skills in infants to conceptual reasoning in adults.

Key Ideas:

  1. Progression Through Integration:
    Development involves combining "chunks" (simple units) from a prior level into more complex structures at the next. For example:

    • In infancy, a baby moves from basic hand movements (stage 0) to integrating grasping and reaching (stage 1) and then pulling objects toward them (stage 2).
    • Cognitively, a concept like volume integrates simpler concepts of length and width to form a new synthesis.
  2. Epistemological Development:
    Children's understanding of the world evolves through these same principles:

    • A young child struggles to take another's perspective, assuming others see what they see (egocentrism).
    • Similarly, they might have an intuitive grasp of size or length but fail to grasp volume until those simpler ideas are integrated.

3. Stages of Complexity (Map)

At each stage of development, the level is defined by how many previous elements (or "chunks") are integrated into the new skill or concept. These levels reflect hierarchical complexity:

  • Early levels involve basic sensory-motor tasks.
  • Higher levels, particularly in adults, involve integrating abstract concepts or reasoning systems.

Highly developed maps started to emerge in 1980s and get refined over the following decades, most notably Models of Hierarchical Complexity by Michael Commons and colleagues and Kurt Fischer's Dynamic Skills Theory

4. Measuring Conceptual Complexity:

Researchers like Theo Dawson (Kurt Fischer's student) and colleagues have created tools for assessing conceptual complexity by analyzing language and reasoning.

They use a "dictionary of concepts" to identify the complexity of ideas expressed.

This approach distinguishes between superficial use of terms (e.g., a young child parroting "volume" without grasping it) and genuine conceptual understanding.

The framework identifies 14 levels of complexity, though most individuals plateau around levels 7 or 8 (with higher levels being rare).

5. Applications to Adult Development:

In adulthood, this hierarchical progression applies to increasingly abstract reasoning:

  • For example, someone may synthesize concepts from multiple systems into a new framework (e.g., integrating scientific disciplines or ethical paradigms).
  • These stages are not merely about knowledge but reflect the ability to integrate and apply ideas in increasingly systemic ways.

This approach provides a structured way to understand and measure human development, highlighting the importance of integration and the iterative nature of progress. Would you like to explore its application in specific domains, such as education or leadership?

So, let's start here. Start with the idea, I would say. Which is that you see these progressions of behaviour Both in families, physically, as a little baby, the child can't really coordinate his hands, and it builds up in a complex motion. What's most serious is epistemology, how we notice, how we think. So, young children can't take the physical perspective of a knife. If they can see something, they see what everyone else can see it. Or, just making a reasoning about volume. Children can have a sense of length, and maybe size, like crude science, they can have a sense of volume. Now, at the genetic point, it's more relevant. But, the thing to do is this. How does these new moments come about? How do these new shifts come about? Well, they sort of combine blocks of the previous level into a new chunk. So, I don't know, let's take the example of volume. Volume is a combination of two lengths, in a way. So, you can see that there's a new concept, and it's built by taking two basic concepts, the lowest, of length, and integrating it into one new concept called volume. So, there's this idea that, at each stage of the developmental pathway, you're iterating concepts, or activities, or skills, at the previous level, into a new synthesis. And, this is the basic idea of that. Well, you can basically think of measuring, assessing skill complexity. How many chunks go into, you know, or how many levels up the hierarchy are we from the most basic chunks? So, you know, stage one, we have the most basic chunks, but as the baby's moving, it might be just moving its hands. Then there's grafting, and then there's pulling, which would be, you know, gravitory and pull towards them. They've integrated, you know, first they've integrated reaching, grafting. That's already stage one, and then they've integrated another motion, which is pulling towards them. That's stage two, so that's stage zero, so we've gone through two. And, as we've got those levels, to define our level by how many students we've integrated. Luckily. Now, you can then, broadly, when people are talking about concepts, or if people have language, people are older, they're doing adult care, we can look at concepts to help define, to protect people with the concepts people are using. So, concepts themselves integrate, I can say that, simple concepts, volumes of length. And you can sort of build up a dictionary. And that's what Theo Dawson and his colleagues have done, to build up a dictionary. Now, it's a bit of fussy, because work can be used, a child, a very young child, could use a concept of volume, but not nearly as standard. You have to be a bit fussy when you do this only. But essentially, you have a dictionary of concepts, and you can then look at what someone says, when you ask them to use a concept. And you can then classify that, in terms of its conceptual complexity, and that gives you, in their case, about 14 different levels. And most people, kind of max out, about seven, so it's just level eight, level 12. So…
