Written production studies investigating central processing have ignored research on the peripheral components of movement execution, and vice versa. This study attempts to integrate both approaches and provide evidence that central and peripheral processes interact during word production. French participants wrote regular words (e.g. FORME), irregular words (e.g. FEMME) and pseudo-words (e.g. FARNE) on a digitiser. Pseudo-words yielded longer latencies than regular words. Letter durations were greater for words at earlier letter positions and greater for pseudo-words at the later positions. Letter durations were longer for irregular than regular words. The effect was modulated by the position of the irregularity. These findings indicate that movement production can be affected by lexical and sublexical variables that regulate spelling processes. They suggest that central processing is not completely finished before movement initiation and affects peripheral writing mechanisms in a cascaded manner. Lexical and sublexical processing does not cascade to the same extent.
书面产出研究调查了中枢处理过程，却忽视了对运动执行的周边成分的研究，反之亦然。本研究试图整合这两种方法，并提供证据表明在单词生成过程中，中枢和周边过程相互作用。法国参与者在数字转换器上书写规则词（例如 FORME）、不规则词（例如 FEMME）和伪词（例如 FARNE）。伪词比规则词产生更长的潜伏期。在较早的字母位置，单词的字母持续时间更长，而在较晚的位置，伪词的字母持续时间更长。不规则词的字母持续时间长于规则词。这种效果受到不规则性位置的调节。这些发现表明，运动生成可能会受到调节拼写过程的词汇和亚词汇变量的影响。它们表明，中枢处理在运动启动之前并未完全完成，并以级联方式影响外围书写机制。词汇和亚词汇处理不会以相同的程度级联。
