Answer:The understanding of conservation
Explanation:
The law of conservation states that the amount of something is preserved even when the shape is altered or even when that thing is deformed.

Psychology is the science that is concerned with studying human subjectivity. It acts both on visible human expressions (behaviors) and on those that cannot be seen, such as our thoughts.
In the middle of the <u>19th century</u> there was the scientific development of psychology, which united the philosophies of the mind with the studies of physiology. In the 18th century there were already studies of the mind, but without the method and rigor with which it was studied in the 19th century.
Before this period, at the beginning of the 13th century, Christian Wolff was the first to use the name psychology to refer to the study of the mind. His method divided psychology in two, which are: empirical psychology and rational psychology. The data of the mind that resulted from the observation of oneself and other people was called empirical psychology and rational psychology interpreted the data obtained in empirical psychology through the use of reason and logic.
As with many areas of knowledge, Psychology presents different study approaches. As an example of schools of Psychology, we have Behaviorism and Psychoanalysis.
