This is a report of the results of an investigation of a test of plurality and past tense in standard English (SE). This research replicated Gleason's 1957-58 study in Boston. The subjects were 27 speakers of Hawaiian Creole English (HCE) in a kindergarten class in Honolulu. The results showed that the children produced very few SE plural and past tense forms. Several interpretations of the results are given. First, HCE-speaking children do not possess the categories of either past tense or plurality. Secondly, the experiment failed, not the children, who in other settings, produce plural forms. With regard to past tense formation, there was probably interference from a Creole rule. In addition, the test situation may have been threatening to the child for cultural reasons. Finally, the test and the testing situation may have been adequate, but the complex language situation in Hawaii may tend to delay complete language development. It is concluded that the same test is not always appropriate in all cultures and that such an investigation can produce damaging results if it is not interpreted properly. (Author/AMH)
