The present study investigates affective-motivational, attention, and learning effects of unexplored emotional design manipulation: "Contextual animation" (animation of contextual elements) in multimedia learning game (MLGs) for children. Participants (N = 134; M[subscript age] = 9.25; Grades 3 and 4) learned either from an experimental version of the MLG with a high amount of contextual animation or from an identical MLG with no contextual animation (control). Children strongly preferred (X[superscript 2] = 87.04, p < 0.001) and found the experimental version more attractive (p < 0.001, d = -1.11). No significant differences in overall enjoyment and learning outcomes were found. Attention differences, measured by dwell times and fixation durations, were small and reached only borderline significance (p = 0.035; d = -0.39). The implication is that contextual animation in MLG for children increases such instructional materials' attractiveness without compromising cognitive processes needed for learning; however, it does not lead to their higher instructional efficiency.
