Answer:
Explanation: When the perspective and norms in society change, and there is a relatively slower development of nonmaterial culture compared to changes in material culture such as technology, this is called "cultural lag."
Cultural lag refers to the idea that changes in material culture, such as technology and infrastructure, can develop more quickly than changes in nonmaterial culture, such as values, norms, and beliefs. This can create a gap between the two, where material culture may advance faster than society's ability to adapt to the changes it brings. This can lead to social problems, as society struggles to adjust to new technologies and ways of life, which can cause conflict and social disorganization. The concept of cultural lag was first introduced by sociologist William F. Ogburn in the early 20th century.
