About

The disorder of oral language development is defined by the delay in language acquisition in children who possess efficient auditory acuity and normal non verbal intellect.

The diversity of language developement disorders depends either in the expressive level or in the receptive level leading to divers syndromes and symptoms. These syndromes and symptoms are regrouped under the name of STOL (Specific Troubles of Oral Language).

In the current project the visual exploitation and learning capability of children presenting a STOL condition will be compared to patients with a normal development. The investigator's hypothesis is as follows: STOL patients for whom the STOL disorder is reduced between 4 and 7 years of age will present a better performance at verbal memorisation, compared to patients with a persistent STOL condition after the age of 6.

Enrollment: 264 estimated patients

Sex: All

Ages: 45 to 95 months old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria for STOL patients:

• Child aged between 45 and 95 months at inclusion
• A score > or equal to 5 percentile on the non verbal intelligence test (PM47)
• Patient diagnosed with STOL by the neuropediatric medical team
• Coverage of the social insurance
• Consent form signed by the parents or the legal representative of the child
• Normal or corrected sight
• Normal hearing

Inclusion Criteria for control patients:

• Child aged between 45 and 95 months on the day of inclusion
• A score > or equal to 5 percentile on the non verbal intelligence test (PM47)
• Child who did not receive any speech therapy
• Coverage of the social insurance
• Consent form signed by the parents or the legal representative of the child
• Normal or corrected sight
• Normal hearing

Exclusion Criteria for STOL patients:

• Mother language other than French
• Score < to 5 percentile on the non verbal intelligence test (PM47)
• Child with pervasive developmental disorder

Exclusion Criteria for control patients:

• Mother language other than French
• Score < to 5 percentile on the non verbal intelligence test (PM47)
• Child who received speech therapy

Trial design

264 participants in 2 patient groups

STOL group

Description:

STOL children will be recruited in the neuropediatric unit at the GHICL in Lille. Children will be followed and we will determine if capacities of verbal memory of the children presenting STOL diagnosed at an early stage of their development (before 6 years) are predictive of the evolution of the disorder according to their cognitive profile and more specifically, their language profile as well as their tests performances. The participants' eye movements ( visual world paradigm or eye tracking) will be recorded in order to determine the interplay between linguistic and visual information processing. Patients with a persistent STOL will be identified at the end of the follow up.

Treatment:

Other: Eye Tracking

Control group

Description:

Children with no language development disorder willing to participate in the study will be recruited at school. The participants' eye movements ( visual world paradigm or eye tracking) will be recorded in order to determine the interplay between linguistic and visual information processing.

Treatment:

Other: Eye Tracking
