An experimental test for achievement motivation which consists of 100 pictures of imaginary figures called gumpgookies was tested on Head Start children. On each picture, two gumpgookies are presented in a semi-structured situation, each engaged in behaviors that reflect different degrees of motivation to achieve. The child being tested is asked to select the gumpgookie on each picture which is most like himself, doing what he would do. Subjects were 179 Negro, Mexican-American, and Anglo children. Parent interview data were examined and subscales were constructed to assess educational opportunities, aspirations and attitudes, physical control, rejection, guilt, and reaction to infraction. The 100 items of the test were classified depending on (1) verbal clues alone, (2) visual clues alone, (3) both verbal and visual clues; and were also classified as either short or long and easy or hard. An item analysis indicated that certain subjects responded positionally throughout the test. Some items were eliminated because of lack of response consistency on a retest. Although positional preference problems with the version of the test used in this study have necessitated major alterations, a new version of the test has been developed which should significantly decrease the positional response set.
