Morphological processing in written word production is based on orthography rather than semantics.

Area of Science:

• Psycholinguistics
• Cognitive Neuroscience
• Computational Linguistics

Background:

• Written word production involves complex central and peripheral processes.
• Morphological units in the lexicon are known to influence handwriting dynamics.
• Understanding morphological representation is key to explaining written word production.

Purpose of the Study:

• To investigate the representation level of morphological information in the French lexicon during written word production.
• To differentiate between morpho-orthographic and morpho-semantic processing using pseudo-derived primes.
• To examine the influence of morphological priming on handwriting dynamics.

Main Methods:

• Two priming experiments were conducted using derived, pseudo-derived, and unrelated primes.
• Experiment 1 utilized a learning-recall task measuring writing latency and duration.
• Experiment 2 employed a word pair copying task measuring inter-word and writing duration.

Main Results:

• Morphological priming effects were observed in both experiments.
• Priming influenced writing latency in Experiment 1 and writing duration in Experiment 2.
• Similar priming patterns were found for derived and pseudo-derived conditions, suggesting morpho-orthographic processing.

Conclusions:

• Morphemes are processed at the morpho-orthographic representation level during written word production.
• Morphemes function as grouping units in handwriting.
• This grouping process operates independently of the morphemes' semantic meaning.
