Computer-generated slide graphics have significantly altered the face of audiovisual presentations. However, it remains to be determined if dramatic effects enhance presentation clarity and increase information retrieval. This study compared color combination and print type graphics. Ninety medical students were shown a 29-minute, 45-slide presentation addressing aspects of plastic surgery. Each slide represented one of 15 color combinations and one of 3 fonts. The students studied each slide for 10 seconds and then in 25 seconds recorded all information they could recall. Statistical analysis (using ANOVA) revealed a significant difference in information retrieval among slides and a significant interaction between color and font. The "best" was orange block print on a raspberry background. The "worst" was yellow cursive print on a black background. This study demonstrated that (1) color influences information gleaned from a slide presentation and (2) font type simplicity may result in improved retention.
计算机生成的幻灯片图形显著改变了视听演示的面貌。然而，戏剧性效果是否能提高演示清晰度并增加信息检索量仍有待确定。本研究比较了颜色组合和字体类型的图形。向90名医学生展示了一个时长29分钟、包含45张幻灯片的关于整形手术方面的演示。每张幻灯片代表15种颜色组合之一和3种字体之一。学生们每张幻灯片研究10秒，然后在25秒内记录下他们能回忆起的所有信息。统计分析（使用方差分析）显示，幻灯片之间在信息检索方面存在显著差异，颜色和字体之间存在显著交互作用。“最佳”组合是树莓色背景上的橙色粗体字。“最差”组合是黑色背景上的黄色草体字。这项研究表明：（1）颜色会影响从幻灯片演示中获取的信息；（2）字体类型简洁可能会提高记忆效果。
