Since its inception, the Rorschach Inkblot Test (RIT) was viewed as a controversial personality test until John Exner, an American psychologist, developed the Comprehensive System (CS). After Exner’s passing in 2006, his family assumed the CS copyright. In 2009, the Exner family decided to preserve the status quo of CS to honor Exner’s contributions to psychology. However, this decision meant that the flaws of CS could no longer be rectified, which resulted in the creation of a new Rorschach system, the Rorschach Performance Assessment System (R-PAS). The present literature review addresses the origin of the RIT, core features of the CS and the R-PAS, comparisons between the CS and the R-PAS, and possible future developments of the RIT. Given the growing international interest in the R-PAS, researchers in Taiwan should pay more attention to this rising force in the field of personality test.
