常规操作通常假定由分层组织的过程和表示来控制。在打字理论领域，单词级信息被假定为激活输入单词中每个字母所需的组成击键。我们使用一种新颖的单字母探针技术直接测试了这一假设。实验对象被提示一个视觉或听觉单词，或一个视觉上随机呈现的辅音字符串，然后被要求从启动中输入一个字母或另一个随机选择的字母。相对于随机选择的字母。对视觉和听觉单词启动词中包含的首、中、尾字母的探测反应加快，而对随机辅音启动词中包含的中、尾字母的探测反应不加快。这表明单词级别的信息导致了组成击键的并行激活，这与分层处理是一致的。讨论了分层处理在打字和常规操作中的作用。
Routine actions are commonly assumed to be controlled by hierarchically organized processes and representations. In the domain of typing theories, word-level information is assumed to activate the constituent keystrokes required to type each letter in a word. We tested this assumption directly using a novel single-letter probe technique. Subjects were primed with a visual or auditory word or a visually presented random consonant string and then probed to type a single letter from the prime or another randomly selected letter. Relative to randomly selected letters. probe responses were speeded for first, middle, and last letters contained in visual and auditory word primes but not for middle and last letters contained in random consonant primes. This suggests that word-level information causes parallel activation of constituent keystrokes, consistent with hierarchical processing. The role of hierarchical processing in typing and routine action is discussed.
