Two experiments examined the time course of the availability of perceptual and conceptual information in priming on the word fragment completion test. Subjects encoded primes as either visual words, auditory words, or pictures. In Experiment 1, word fragments were exposed for either 500 ms, 1 s, 5 s, or 12 s. Only the visual words produced priming at the 500-ms and 1-s exposure times. In Experiment 2, subjects were allowed up to 20 s to solve each fragment; response latencies were recorded and cumulative response curves were generated. Visually primed fragments were solved at a faster rate than either auditorily or pictorially primed fragments. The results suggest that although conceptual processing can contribute to word fragment priming, perceptual processes are recruited earlier and at a faster rate.
两项实验研究了在单词片段完成测试中启动效应里感知信息和概念信息可用性的时间进程。实验对象将启动刺激编码为视觉单词、听觉单词或图片。在实验1中，单词片段的呈现时间分别为500毫秒、1秒、5秒或12秒。只有视觉单词在500毫秒和1秒的呈现时间产生了启动效应。在实验2中，允许实验对象最多20秒来解决每个片段；记录反应潜伏期并生成累积反应曲线。视觉启动的片段比听觉或图片启动的片段解决速度更快。结果表明，虽然概念加工可以促进单词片段启动效应，但感知过程更早且更快地被调用。
