Projective techniques are indirect interview methods used in psychology to understand a respondent's underlying motives, attitudes, or feelings that they may not openly reveal. These techniques involve having respondents project their own unconscious perspectives when interpreting ambiguous stimuli like ink blots, pictures, or sentence/story completions. Some common projective techniques discussed in the document are word association tests, Rorschach ink blots, TAT pictures, role playing exercises, and sociometry which maps social relationships in a group. Projective techniques are useful for motivational and attitude research.
