Answer:
Social constructivist
Explanation:
According to Social constructivist theory knowledge is created and spread through interactions with others and is responsible for human development.
Knowledge is developed according to the needs of society. It is needed to tackle the problems that society is facing in a particular region. As the problems people face in different regions are different the knowledge which is developed is different. This results in the development of different cultures around the world.
Emotions are caused due to a change in the natural environment of a person. In certain cultures a specific type of emotional response is encouraged. This happens as with a specific type of environment certain emotional responses are considered best to deal with the situation. The situations vary from region to region.
Hence, the approach the researcher is demonstrating is Social constructivist.
