Answer:
<em>Object permanence </em>
Explanation:
The permanence of the object is the understanding that objects continue to exist even if they cannot be seen, heard or, failing that, touched. The permanence of objects is studied by developmental psychology, which is a branch of psychology that is responsible for the study of the development of the social and mental capacities of babies and children.
It is not known exactly the moment in which the understanding of the permanence of the object is acquired, although it is estimated that it could arise within the first two years of life, although it is also thought that it is an innate or incorporated ability from the birth.
<em>Therefore, when imagining that he is sitting in the library and then a person is seen passing behind the pillar, and then emerges from the other side of a more distant pillar, there is talk of a clear example of permanence of the object, of which the Researchers create impossible scenarios to know if children have developed this capacity.</em>
