本实验考察了大学生书面语言水平的个体差异是否可以预测掩蔽启动词汇判断任务所采用的词汇提取的早期阶段。为了区分亚词汇促进和词汇竞争对掩蔽启动的作用，对100名大学生的阅读、拼写和词汇量进行了测试，比较了转置字母(TL)启动(如Sung Snug；Salb Splet)和相邻启动(如Snig Snug；Sleb Splet)的词汇性效应。整个样本的数据显示，来自非词启动的促进作用，而来自词启动的抑制作用。包括个体差异测量在内的线性混合模型显示，在包含阅读、拼写和词汇共同差异的主成分上得分越高，来自目标语单词启动的抑制作用越强，来自相邻非单词启动的促进作用也越强。这些发现与阅读的词汇质量假说相一致，该假说预测，熟练的读者在发展精确的特定拼写表征的程度上存在差异。
This experiment investigated whether individual differences in written language proficiency among university students predict the early stages of lexical retrieval tapped by the masked form priming lexical decision task. To separate the contributions of sublexical facilitation and lexical competition to masked form priming, the effects of prime lexicality were directly compared for both transposed-letter (TL) primes (e.g., sung SNUG; salb SLAB) and neighbor primes (e.g., snag SNUG; sleb SLAB) in a sample of 100 university students assessed on measures of reading, spelling and vocabulary. The data for the whole sample showed facilitation from nonword primes, but inhibition from word primes. Linear mixed models including the individual difference measures showed that higher scores on a principal component that captured the shared variance among reading, spelling, and vocabulary were associated with both stronger inhibition from TL word primes and stronger facilitation from neighbor nonword primes. These findings are consistent with the lexical quality hypothesis of reading that predicts that skilled readers vary in the extent to which they have developed precisely specified orthographic representations.
