Handwritten Text Production in Adults With Autism
The main objective is to assess the psycholinguistic and graphomotor characteristics of written production in patients with ASD.

The secondary objectives are:

Identifying links between specific deficits of ASD and difficulties in written production.
Identifying links between the severity of ASD and difficulties in written production.

The primary evaluation criterion is the quantity of written production, namely the number of words produced in 5 minutes on a text copying task (BHK) and in 15 minutes on each of the two written production tasks (descriptive and persuasive).

The secondary evaluation criteria are:

Graphomotor indicators of written production (writing speed, pre-writing time, pause time, writing time, handwriting size, results obtained in BHK (number of words produced, letter height, line parallelism, telescoping, ambiguous letters).
Cognitive and psycholinguistic indicators of written production (presence of titles, presence of paragraphs, number of sentences, number of words per sentence, lexical richness, lexical field, number of action verbs, morphological complexity, number of syntactic markers related to oneself, number of syntactic markers related to others, number of spelling errors, evaluation of the overall quality of the produced text).
Results obtained in tests (writing habits questionnaire, Autism Diagnostic Observation Scale (second edition), Wechsler Adult Intelligence Scale (fourth edition) - Similarities subtest, Wechsler Adult Intelligence Scale (fourth edition) - Vocabulary subtest, Rey Figure, MASC).
