We examined if cross-modal priming (print to speech) was greater for participants who were aware of the presence of letters in the experiment. Experiment 1 determined that word primes displayed at 47ms were adequately masked. In Experiment 2 (a,b) with primes displayed at 47ms masked priming occurred for within-mode printed targets but not for spoken ones. Experiment 3, with spoken targets, presented primes at two different durations (59, 71ms) and priming was found for participants who reported seeing letters but not for those who did not. The results are discussed in terms how the link between prime and target representations might be strengthened even by cursory awareness of the prime and what this tells us about priming.
我们研究了对于那些知晓实验中字母存在的参与者而言，跨模态启动效应（从印刷体到语音）是否更强。实验1确定了以47毫秒呈现的单词启动刺激被充分掩蔽。在实验2（a、b）中，以47毫秒呈现启动刺激时，对于模式内的印刷体目标出现了掩蔽启动效应，但对于语音目标则未出现。实验3中，对于语音目标，以两种不同时长（59毫秒、71毫秒）呈现启动刺激，结果发现，报告看到字母的参与者出现了启动效应，而未报告看到字母的参与者则未出现启动效应。我们将根据即使对启动刺激只有粗略的觉知，启动刺激与目标表征之间的联系如何可能得到加强，以及这对启动效应意味着什么来讨论这些结果。
