A type of projective test in which the respondent is presented with the first few words of a series of sentences and is asked to fill in the missing words. Typical items are My greatest fear is … ; I only wish I had … . One of the most carefully constructed versions is the Rotter Incomplete Sentences Blank. The technique was first used in 1897 by the German psychologist Hermann von Ebbinghaus (1850–1909) as an intelligence test. Also called an incomplete sentences test.
