Quantitative development refers to developing capacities such as cognition, volition, affect, skills, etc. It is indicated by an increase in certain characteristics (some of which roughly correspond to the characteristics of biological evolution). The list of such characteristics is proposed below. This list may not be exhaustive and does not imply that all of them are necessary:

  • Dynamism (e.g. interest, curiosity, a desire to learn)
  • Complexity and differentiation (e.g. being able to recognise the composite elements of a whole; a capacity to grasp different viewpoints)
  • Organisation and integration (e.g. an ability to connect and keep together various elements of a concept or operational segments of an activity)
  • Perspective (e.g. considering long term plans, other people, global issues)
  • Refinement (e.g. sensitivity to nuances, details or subtle points)
  • Diversity and versatility (e.g. a variety of interests, knowledge or skills)
  • Flexibility (e.g. an ability to incorporate or adapt to a change)
  • Creativity (e.g. capacity to generate something new)
  • Internal control (e.g. an ability to delay immediate gratification, self-discipline)
  • Productivity (efficiency in utilising one's potentials and energy)
