About this study

Exploring the non-symbolic and symbolic arithmetic competencies in two groups of children (5-, and 7-year-olds). Additionally, we explored the relationship with domain-general factors such as inhibition and attention. Recorded fMRI.

Read the detailed description

Using T2*-weighted eip imaging, we measured BOLD response in two cohorts of healthy children while they were doing different cognitive tasks in the scanner. These tasks included solving non-symbolic (i.e. sets of elements) and symbolic (i.e. Arabic digits) addition and subtraction problems, a color control task, an attentional task measuring different facets of spatial attention, and a task measuring inhibition. We also recorded a high-resolution anatomical scan of the brain.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • cognitive tasksOther

    no intervention in a medical sense, only observing changes of BOLD signal during different experimental conditions in cognitive tasks (arithmetic, attention, inhibition)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. BOLD response

    changes of BOLD response under different experimental conditions (non-symbolic arithmetic; symbolic arithmetic; inhibition; attention)

    Measured: BOLD response recorded during fMRI session

  2. BOLD response

    changes of BOLD response in experimental conditions

    Measured: during fMRI session

Questions about this trial

What is this clinical trial studying?

A study testing cognitive tasks in people with No Condition, run by Centre Hospitalier St Anne at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BOLD response (time frame: BOLD response recorded during fMRI session). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2024.
