First demonstrated in the 1970s, social loafing was a consistent finding in several psychological studies conducted with american and european subjects. but when similar studies were conducted with chinese participants the opposite was found to be true. this variation has reminded researchers about the importance of studying the perspective of psychology.

I believe the answer is: Social Loafing

Social loafing refers to a situation when a person is making less effort when that person is working in the group compared to when working individually. This type of behaviour tend to be created when that person felt that the effort of other members would make his/her lack of performance unnoticeable.

The variation which is mentioned above has reminded researchers about the importance of studying the cross-cultural perspective of psychology.

Explanation:

The psychology of people is majorly influenced by the region where they live in. The studies conducted on social loafing in the United States and Europe exhibited different results than the same studies carried out in China because the tendency towards working in a group of the Chinese is opposite to the tendency of the people in the US and Europe. This difference is majorly due to the difference in cultures.
