Clayton P. Alderfer (1972), of Yale University, reformulated Maslow’s theory, to align it more closely with empirical research. According to Aldefer, there are three groups of core needs-Existence, Relatedness and Growth coded as (ERG THEORY.). The ERG model and Maslow’s theory are similar. Aldefers three cores needs include the five needs of Maslow’s need hierarchy and also defined the differences between the two theories. First of all, Alderfer has recognized that more than one need can be operative at the same time, and second, if the gratification of a higher level need is stifled, the desire to satisfied lower level needs icrease.In general, ERG theory represents a more valid version of the Maslowian need hierarchy.
