Projective tests are based on defence mechanism that indicates:a.Attributing an individual’s unacceptable thoughts, feelings and motives to another personb.Repressing memories, feelings, or thought, these things are no longer accessible in the client’s consciousnessc.Satisfying an impulse (eg. aggression) with a substitute objectd.Substitution of a safe and reasonable explanation for the actual (but threatening) cause of behaviour

Projective tests are based on the defense mechanism known as projection. This refers to attributing an individual’s unacceptable thoughts, feelings, and motives to another person. This is a way for a person to deal with their own unacceptable thoughts, feelings, and motives by projecting them onto someone else.

Here's a step-by-step breakdown of the defense mechanisms mentioned:

a. Projection: This is the defense mechanism that projective tests are based on. It involves attributing one's own unacceptable thoughts, feelings, and motives to another person.

b. Repression: This defense mechanism involves repressing memories, feelings, or thoughts so that they are no longer accessible in the person's consciousness. This is a way for a person to avoid dealing with painful or uncomfortable thoughts or feelings.

c. Displacement: This defense mechanism involves satisfying an impulse, such as aggression, with a substitute object. This is a way for a person to express negative feelings or impulses without directing them at the appropriate or original source.

d. Rationalization: This defense mechanism involves substituting a safe and reasonable explanation for the actual (but threatening) cause of behavior. This is a way for a person to justify or make excuses for their own negative behaviors or feelings.
