Document Summary
The answer must come from needs, feelings, experiences, thought processes and other hidden aspects of the mind: when evaluated as psychometric instruments, the large majority makes a poor showing. They are specific, directly observed responses to particular stimuli: fundamental difficulty: a psychologist cannot be sure what they mean. The answer and the validity of the answer depend critically on the test interpreter: only tat is consistently scored, the rorschach, the correlation coefficient between scores garnered averaged about . 33. So if someone is pretending, they will be identified immediately. S data gathered, or direct and undisguised self-reports, and therefore have face validity. First, each item must mean the same thing to the person who takes the test as it did to the psychologist who wrote it. Second, the person who completes the form must be able to make an accurate self-assessment. Third, the person who completes the test must be wiling to report his self-assessment accurately and without distortion.
