Abstract
Threshold theory predicts a positive correlation between IQ and creativity scores up to an IQ level of 120 and no correlation above this threshold. Primary school children were tested at beginning (N = 98) and ending (N = 70) of the school year. Participants performed the standard progressive matrices (SPM) and the Test of Creative Thinking—Drawing Production (TCT-DP). Each child with IQ ≥ 120 was grade-and-gender matched to a child with IQ < 120. Results in accordance with the threshold theory were found only for female children in the highest grade level (Grade 4). Longitudinal analysis implies that a subgroup of children goes down in IQ and creativity simultaneously, possibly due to motivational issues. Their correlated scores may be a source of evidence for the threshold theory. The relationship between intelligence and creativity is not straightforward and depends on a combination of factors including grade level and gender.
