Individual interest was examined as a moderator of effects of situational factors designed to catch and hold task interest. In Study 1, 96 college students learned a math technique with materials enhanced with collative features (catch) versus not. Catch promoted motivation among participants with low individual interest in math (IIM) but hampered motivation among those with high IIM. In Study 2 (n = 145), catch was crossed with a hold manipulation, emphasizing utility. Effects of each manipulation depended on IIM. The catch results were similar to those in Study 1. Hold promoted motivation among participants with high IIM and undermined it among participants with low IIM. Discussion centers on the intersection of individual and situational interest.
