Progress is defined as the accumulation of knowledge over long periods of time.

In psychology, progress refers to the process of improvement or advancement in a particular area. This can refer to personal growth or development, as well as progress made in the understanding or treatment of psychological disorders or other areas of study.

There are many ways in which progress can be measured or evaluated in psychology. For example, a person might track their progress in therapy by noting changes in their symptoms, mood, or behaviors. In research, progress might be measured by the advancement of knowledge or understanding of a particular topic, or by the development of new treatments or interventions.

Examples of progress in psychology might include a person who has made significant improvements in their mental health as a result of therapy, or a researcher who has made a significant discovery that advances the understanding of a particular psychological phenomenon.
