Answer:

Continuity

Stage/Discontinuity

Explanation:

In psychology, there are different models used to explain the way people develop and go through changes in their lifespan.

According to the continuity model of development, changes and development are view as a continuous process that is gradual and cumulative. For example, when a child learns a new ability he gradually acquires the necessary skills in a continuous process.

On the other side, there is the discontinuity model of development, also known as stage model. According to this model, development consists on different stages. This model believes that people go through different stage that are qualitatively different from each other and they are not in a continuous non stop process but rather they take place in periods of rapid and abrupt change separated from each other by periods of little change.

In this example, <u>Dr. Johan believes in the model that says that changes occur at a relatively regular pace,</u> this would be the Continuity model.

On the other hand, <u>Dr. Ziback believes in the model that says that there are periods of rapid and abrupt change separated by periods of very little change, </u>this would be the Discontinuiy/Stage model.
