Answer: VALS
Explanation:
VALS which stands for Values and Lifestyles was introduced in 1978 by the California consulting firm of SRI International and is a system whereby people are grouped according to psychological and social theories to predict their future buying behavior.
Three main categories exist being the NEED DIRECTED CONSUMERS who purchase strictly on their needs, INNER DIRECTED CONSUMERS who make purchases based on some inner need and OUTER DIRECTED CONSUMERS who make purchases based on how they feel people look at them.
