Q. What do you mean by Trait theory?
Trait theory is a main departure from the qualitative or subjective approach to personality measurement. It postulates that persons possess innate psychological traits (example novelty seeking, innovativeness, need for cognition and materialism) to a greater or lesser degree and that these traits can be measured by specially designed scales or inventories. For the reason that they are simple to use and to score and can be self-administered.
