We tested 462 primary students (244 boys and 218 girls) in Grades 1, 2, and 3 from 20 primary schools in Hong Kong. Their ideational fluency was assessed by using 2 items each on 3 types of verbal tasks (instances, uses, and similarities) and 2 types of figural tasks (pattern meanings and line meanings) from the Wallach-Kogan tests. On the average, students generated about 20 instances, gave 9 alternative uses of a common object, listed 11 possible similarities between a pair of named objects, and gave 13 and 15 possible meanings for visual patterns and lines, respectively. Although boys scored consistently higher in ideational fluency than girls on verbal tasks, significant gender differences did not emerge for figural tasks. Significantly higher scores on ideational fluency were evident for students in higher grades especially for verbal tasks. The use of the Wallach-Kogan tests in the assessment of divergent thinking ability and creativity for Chinese children is discussed.[Copyright of Creativity Research Journal is the property of Lawrence Erlbaum Associates.
