The Validity of the Measurement of Originality

To explore the construct validity of one of the originality scores of the Torrance Tests of Creative Thinking, the investigators examined the responses of undergraduates to different instructions for the "Unusual Uses of a Cardboard Box" activity. One group obtained standard instructions, whereas another received vague instructions. After effects of fluency were partialled out, originality scores were substantially higher for the vague instructions group. This finding raises important questions about whether the typical measurement of originality depends on what stimulus materials are used, as well as on how responses should be scored.
