“…Piotrowski (110), using the Rorschach test, felt that, on the whole, the difference in pre-and post-treatment records paralleled the clinical improvement. This improvement was manifested on the Rorschach test by (1) improvement in speed and ease of answering, (2) better logical content of responses and less mixing of description and interpretation, (3) an increase in the number and quality of movement responses, (4) an increase in the number and percentage of form-color concepts, (5) an increase in percentage of sharply perceived forms, and (6) good percepts and integrating capacity. Signs of predictive value for good prognosis were devised (112) and described as (1) variety, indicating no concepts used more than twice, (2) generic term, referring to patient's attention to logical hierarchy, (3) evidence, or self-critical evaluation of responses for "adequacy of fit," (4) color response, or at least one color interpretation except simple color-naming, (5) indirect color, or evidence of attention to color-areas, and (6) demurring, or holding back one or more responses.…”
