Final answer:
The FALSE statement regarding the tightness/looseness dimension is that it is the only cultural dimension identified by researchers, when in fact, there are several other cultural and personality dimensions like the Five Factor Model and Hofstede's cultural dimensions that are also considered relevant.
Step-by-step explanation:
All of the following statements about the tightness/looseness dimension are true except one. The statement which is FALSE is: D) The tightness/looseness dimension is the only cultural dimension identified by researchers, and there are no other relevant dimensions.
Cultural psychologist Michele Gelfand proposed the tightness/looseness dimension as a way to understand how different cultures respond and adhere to social norms. This dimension explains that cultures vary in the strength of social norms and the extent to which they enforce conformity. Cultures with high tightness exhibit strict observance of social norms and low tolerance for behavior that deviates from these norms. However, there are other cultural dimensions identified by researchers, such as those found in the Five Factor Model of personality, or the famed Hofstede's cultural dimensions, indicating that the tightness/looseness dimension is not the only cultural dimension considered relevant in the study of cultures and personality.
