92 second- and 116 sixth-graders were taught that an apple is a group of buruna (novel word) for the inclusion instruction or that an apple is a buruna for no inclusion. Then six fruit and five unrelated names were presented in the probe phase, and the subjects were asked to select the names which they thought were a group of buruna for the inclusion instruction or the names which they thought were a buruna for the no-inclusion. The percentages of the subjects who selected the six fruit names, i.e., those who interpreted the novel word as the superordinate category, were greater for the inclusion than for the no-inclusion instructions in the probe phase, especially for the sixth-graders.
