Although several studies have found that the sublexical route of spelling has an effect on handwriting movements, the ability of lexical variables to modulate peripheral processes during writing is less clear. This study addresses the hypothesis that word frequency affects writing durations only during writing acquisition, and that at some point of development, the handwriting system becomes a relatively autonomous system unaffected by lexical variables. Spanish children attending Grades 2, 4, and 6 performed a spelling-to-dictation and a copy task in which word frequency was manipulated. Results revealed that written latencies decreased with age, especially between Grades 2 and 4, and that writing durations decreased between these two groups. All these measures were longer during copying but the effect of task on written latencies and in-air pen trajectories was smaller for older children. Crucially, a significant word frequency effect on writing durations was observed only in Grade 2. This effect was marginally significant in Grade 4 and disappeared in Grade 6. However, all groups showed a similar effect of word frequency on written latencies. These findings suggest that lexical processes impact peripheral processes during writing acquisition and that this influence diminishes to eventually disappear at some point in development.

Orthographic representations of words are indispensable for reading fluency. The ways in which these representations are developed and their resistance to decay are hotly debated topics. The aim of this study was to investigate the influence of semantic and phonological representations on the formation of orthographic representations in a transparent orthography. In order to achieve this objective, an experiment with three conditions was carried out. In the first condition, a group of university students were asked to repeatedly read 10 new words after semantic and phonological training, in the second condition another group of participants read the new words after phonological training, and in the third condition participants read without previous training. Finally, a follow-up session was performed to test the resistance to decay of the orthographic representations. The results showed that participants who had received semantic training formed the representations faster than participants in the other conditions, as indicated by the decrease in length effect. These results indicate the important role of previous knowledge when people face new written words. A month later these orthographic representations still remained in the lexicon of the participants.
