Mary believes that cognitive development is a matter of gradual and almost imperceptible changes over time. Her viewpoint is most directly relevant to the issue of continuity or stages. fluid or crystallized intelligence. behavior or mental processes. nature or nurture. concrete or operational stages.

The answer is continuity or stages.

Explanation:

These opposite approaches, also known as continuity vs. discontinuity, seek to understand the process of human development.

In the example, Mary seems to support to continuity perspective, in which development occurs through slow and seamless changes. On the other hand, the discontinuity issue describes development as divided into different stages.

For example, learning to speak might be a gradual process in which the child is always learning new aspects, as seen by the continuity perspective. The opposite might separate the process into distinct phases, such as social speech, egocentric speech, and more.
