Final answer:
The strength of the humanistic approach that is not represented is the objective measurement of personality; humanistic psychology emphasizes subjective experiences, holistic views, and positive psychology.
Step-by-step explanation:
The humanistic approach to psychology has several strengths, but objective measurement of personality is not one of them. Humanistic psychologists like Abraham Maslow and Carl Rogers emphasized the subjective experience and the growth potential of individuals. They believed in free will, self-determination, and the innate desire of individuals to become the best person they can be, which all contribute to the strength of the humanistic approach. These include Emphasis on subjective experiences, Holistic view of personality, and Influence on positive psychology. However, the objective measurement of personality is more characteristic of trait theories, which rely on more quantifiable and empirical methods, and is not a strength associated with the humanistic approach.
