ロールシャッハ・テスト
In 1961 Holtzman released the Holtzman Inkblot Technique (HIT), also known as the Holtzman Inkblot Test, which he had been developing for the previous ten years. It was designed as a replacement for the Rorschach test which had a number of deficiencies. The HIT was a standardised measurement that was considered to be more reliable than the Rorschach. The test consisted of a series of 45 cards with a single response accepted for each card, as opposed to the Rorschach test which consisted of 10 cards to which multiple responses could be given. However, not all psychologists accept the validity of the HIT. Psychologist H. J. Eysenck stated that a simple 10 minute questionnaire produced better results.
