| Abstract: | Four factor analyses of subtests of three critical thinking tests, a logical reasoning test, and an English test were conducted. Nine group and specific factors were identified. It was concluded that critical thinking is a composite of group and specific factors including: recognition of assumptions; judgments if conclusions follow from evidence given; relevance of evidence; fine discriminations about truth or falsity with which inferences follow. The logical reasoning subtest appeared to represent specific separate variance. The English subtests’ variance overlapped substantially with the critical thinking subtests’ variance. |
