The Colavita effect occurs when participants respond only to the visual element of an audio-visual stimulus. This visual dominance effect is proposed to arise from asymmetric facilitation and inhibition between modalities. It has also been proposed that, unlike adults, children appear predisposed to auditory information. We provide the first quantitative synthesis of studies exploring the Colavita effect, combining data from 70 experiments across 14 studies. A mixed-meta-regression model was applied to assess whether the Colavita effect is influenced by methodological factors and age group tested. Studies reporting response time data were used to test for the presence of asymmetrical facilitation between modalities. Studies with adult participants yielded a medium, approaching large, effect size. Studies exploring the Colavita effect in children yielded no Colavita effect. Across adult and child studies, no methodological factors influenced the effect. Contrary to asymmetrical facilitation, response time data suggested a general slowing under bimodal conditions. These findings suggest that whilst vision dominates in adults, this effect is absent in childhood.

当参与者仅对视听刺激的视觉元素做出反应时，就会发生Colavita效应。提出这种视觉上的主导作用是由于模态之间的不对称促进和抑制而引起的。还已经提出，与成年人不同，儿童似乎倾向于听觉信息。我们结合了14项研究中70项实验的数据，提供了探索Colavita效应的研究的第一份定量综合报告。应用混合元回归模型评估Colavita效应是否受方法论因素和所测试年龄组的影响。报告反应时间数据的研究用于测试模式之间是否存在不对称促进。对成年参与者的研究产生了一个中等的，接近大的效应量。探索儿童可乐维他效应的研究未产生可乐维他效应。在成人和儿童研究中，没有任何方法学因素影响疗效。与不对称促进相反，响应时间数据表明在双峰条件下总体放慢了速度。这些发现表明，虽然视觉在成年人中占主导地位，但这种现象在儿童时期是不存在的。
