This document discusses projective techniques, which are methods used to understand an individual's inner world. Projective techniques are classified into association, construction, completion, choice/ordering, and expressive types of responses. Examples of techniques discussed include word association tests, ink blot tests, Thematic Appreciation Tests (TAT), sentence and story completion tests, play techniques, and role plays. The techniques have advantages of being reliable, eliciting spontaneous responses, and providing easy insights into personality. However, they also have disadvantages like requiring highly trained interviewers, potential for interpreter bias, being costly and time-consuming.
