Purpose: Our objective is to describe the moderating effect of the level of gross motor development on the relationship between physical activity (PA) level and visual perception/memory in girls. Methods: This is a quantitative cross-sectional study with a randomized sample of 85 girls (mean age 7.11 ± 0.74) from Chile. The following models were tested: interaction between PA (light: Model 1; moderate–vigorous: Model 2; vigorous: Model 3; and total PA: Model 4) and motor development level associated with visual perception/memory. Variables that showed interaction were tested according to the Johnson-Newman. Results: The Model 2 explains 13% of visual perception/memory and the Model 4 explains 15%, indicating that the motor development level is a moderator of this relationship. Conclusions: Collectively, our results present evidence that girls with a high level of gross motor skills have a stronger relationship between total PA (and also only moderate–vigorous activity) and visual perception/memory.

目的：我们的目标是描述粗大运动发育水平对女孩体力活动 (PA) 水平和视觉感知/记忆之间关系的调节作用。方法：这是一项定量横断面研究，随机抽取了 85 名来自智利的女孩（平均年龄 7.11 ± 0.74 岁）。测试了以下模型：PA（轻度：模型 1；中度剧烈：模型 2；剧烈：模型 3；总 PA：模型 4）与与视觉感知/记忆相关的运动发育水平之间的相互作用。根据约翰逊-纽曼法对显示相互作用的变量进行了测试。结果：模型 2 解释了 13% 的视觉感知/记忆，模型 4 解释了 15%，表明运动发育水平是这种关系的调节因素。结论：总的来说，我们的结果证明，粗大运动技能水平较高的女孩的总 PA（也仅是中等强度的活动）与视觉感知/记忆之间存在更强的关系。
