Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change?
ankoles [38]

Answer:

Heyya!

Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life.  When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.
