Wannee Tangsawpak (2000) explained in her work that in biological concept,
adaptation would occur to follow the needs of the body or physiological needs,
whereas adaptation in psychological norms occurs by following the needs of the
mind. She found that human adaptation occurrences follow two forcing factors as
below:
1) External forcing refers to demands from the environment and society
since humans need to live in society and interact with other people; they
have to learn and adapt themselves to the main society since they were
children.
2) Internal forcing refers to demands from inside or physiological needs and
also the social experiences that have been gained from in the past, also
some physiological needs such as the needs we have for water, food, and
for mental needs such as love and a sense of belonging.
