Neurocognitive Correlates of the Influence of Number Word Syntax on Magnitude Processing
This study aims to understand how our brains process numbers and if the way we say and structure number words (like 'twenty-one' versus 'one and twenty') changes how we understand them. Researchers will use special brain scans called MRI to look at brain activity while healthy adult volunteers complete tasks involving numbers. The study is divided into two parts, each looking at different aspects of how we handle numbers, such as comparing two-digit numbers and solving simple addition problems. It will help us learn more about the fascinating connection between language and how our brains work with numbers.
At a glance
What is this study about?
Have you ever wondered why numbers like 21 are sometimes said as "twenty-one" and sometimes translated differently in other languages? This study is all about exploring how the language we use for numbers might actually change the way our brains understand and process those numbers. It's like asking if the wiring in our brain for numbers changes depending on how we learned to say them.
The researchers want to see if different ways of naming numbers affect how quickly and accurately we can make sense of them. For example, they'll be looking at how people compare two-digit numbers (like deciding if 25 is bigger or smaller than 52) and how they solve simple addition problems. By using special brain scans called MRI while volunteers do these tasks, the scientists can see which parts of the brain are active. This helps them understand the brain's 'headquarters' for number and language processing.
Ultimately, this research could give us important insights into how our brains learn and work with maths. It might even help us understand why some people find maths harder than others, particularly if their language uses a different system for numbers. It's a fundamental look into the building blocks of how we understand the world around us through numbers and words.
Key takeaways
- This study explores how language affects number processing in the brain.
- It involves healthy adults and uses MRI brain scans.
- You must be 18-45 years old, right-handed, and a native French speaker.
- Individuals with certain medical conditions or implants cannot participate.
- Participation involves a health check and an MRI scan.
- You can withdraw from the study at any time.
Who may be eligible?
To take part in this study, you need to be a healthy adult aged between 18 and 45. It's important that you are right-handed and that French is your native language. You also can't have any major ongoing health conditions.
There are several reasons why you might not be able to join. For instance, if you have any metal in your body (like some pacemakers or certain implants) or if you are very claustrophobic, you won't be able to have an MRI scan, which is a key part of the study. You also can't take part if you've had a history of serious head injuries, certain long-term illnesses (like diabetes or heart conditions), or if you're currently taking medications that might affect your brain activity.
Women who could become pregnant must be using effective contraception to be eligible. The researchers will check your medical history to make sure it's safe for you to participate and that you fit the study requirements.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 45 years old?
- Are you right-handed?
- Is French your native language?
- Do you have any metal implants or serious health conditions that might prevent an MRI scan?
- Are you taking any medications that affect brain function?
- Are you able to travel to GHU Paris for appointments?
What does participation involve?
If you decide to take part, the first step is a pre-selection call to see if you might be a good fit. If so, you'll receive detailed information by mail and then have an appointment in Paris. During this visit, the study team will explain everything carefully, including what's involved and any possible risks, and you'll have the chance to ask questions before deciding to give your consent to participate.
The study involves a medical check-up, where they'll ask about your health history and any medications you're taking. They'll also check your handedness. The main part of the study involves an MRI scan, which is a type of brain scan. During the MRI, you'll likely be asked to complete some computer tasks involving numbers, but the exact duration and number of visits are not specified in this summary. You won't be given any new medications as part of this study.

Common questions
What is an MRI scan?
An MRI (Magnetic Resonance Imaging) is a safe scan that uses strong magnets and radio waves to create detailed pictures of the inside of your body, in this case, your brain.
Will I feel or be given any medication?
No, you will not be given any medication as part of this study, and you should not feel anything during the MRI scan itself, aside from possibly hearing some noise from the machine.
Do I need to be good at maths to take part?
No, you don't need to be a maths expert. The study focuses on how your brain processes numbers, not on your maths ability. The tasks are likely to be straightforward.
How long will the study take?
The information provided does not specify the total duration of the study or how many visits you would need, but the main part involves a selection visit and an MRI scan.
Is the study suitable for everyone?
No, there are strict rules about who can take part, mainly due to the need for an MRI scan and certain health conditions. Please check the eligibility criteria carefully.
