Summary

This study details a patient with dysgraphia who made errors specifically with double letters in handwriting. This finding suggests writing models accurately represent letter doubling information.

Area of Science:

  • Cognitive Neuroscience
  • Linguistics
  • Psychology

Background:

  • Writing process models propose abstract graphemic representations store letter doubling information.
  • This information is thought to be independent of specific letter identity.

Observation:

  • A patient, R.T., exhibited unique perseverative errors exclusively in handwriting geminate (double) letters.
  • Example: 'CORTECCIA' (cortex) was written as 'CORTECCCIA'.

Findings:

  • Perseveration was strictly orthographic, affecting only the written form.
  • The study posits that the geminate feature, after graphic motor program selection, triggers perseverative behavior.

Implications:

  • This specific form of dysgraphia provides evidence for abstract graphemic representations containing explicit letter doubling information.
