EEG and Behavioral Correlates of Temporal Prediction in the Tactile Modality in Schizophrenia
This study is about understanding how people with schizophrenia experience their 'sense of self' and how they predict things using touch. Many people with schizophrenia feel disconnected from their body. Researchers believe problems with this sense of self and judging time might be early signs of psychosis. They are using special tests, including touch, to see if they can measure these feelings objectively. The goal is to find better ways to spot individuals who might be at risk of developing psychosis earlier. This could lead to better and more tailored care, helping people get support sooner rather than later.
At a glance
What is this study about?
Imagine your brain as a brilliant prediction machine, constantly working out what's going to happen next, whether it's catching a ball or knowing when someone will finish a sentence. This study is exploring how people with schizophrenia, a condition that affects how a person thinks, feels, and behaves, use these prediction skills, especially through their sense of touch.
Researchers are particularly interested in two things: a person's 'sense of self' – how connected they feel to their own body and experiences – and how they experience time. It's thought that difficulties with these might be early signs that someone is at risk of developing psychosis, which is a condition where a person has trouble telling what's real from what isn't. Sometimes, people with schizophrenia find it hard to describe these feelings themselves, so scientists are looking for objective ways to measure them.
This study will involve tests that look at how well someone can use the passing of time to predict when something will happen and prepare for it. The team has found before that people who have a less clear sense of their own body might not be as good at using time to prepare for future events. By adding tests that involve touch, they hope to get an even clearer picture and develop more sensitive ways to understand these challenges, ultimately leading to better support for those who need it.
Key takeaways
- This study explores the 'sense of self' and time perception in schizophrenia.
- It uses touch-based tests to understand how people predict events.
- The aim is to find early signs of psychosis to improve support.
- Participation involves specific eligibility criteria.
- It's a research study, not a new treatment trial.
Who may be eligible?
This study is looking for both men and women between the ages of 18 and 60. You need to be signed up for a social security plan, or be a beneficiary of one, and be able to understand and sign a consent form, which explains what the study involves.
There are certain reasons why you might not be able to join. For example, if you have certain drug or alcohol use issues, or have used cannabis recently (within the last two months). You also cannot participate if you have certain neurological conditions, ADHD, or a condition called borderline personality disorder.
This study is not suitable for pregnant or breastfeeding women, or anyone who has significant problems with their senses (like hearing or sight). Also, if you are currently in prison or under court protection, or already taking part in another clinical study that would prevent you from joining this one, you won't be able to take part.
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 60 years old?
- Do you have a social security plan or are a beneficiary?
- Do you not have certain recent drug or alcohol use issues (e.g., cannabis in last 2 months)?
- Are you not pregnant or breastfeeding?
- Do you not have an existing neurological condition, ADHD, or borderline personality disorder?
- Are you able to provide your informed consent?
What does participation involve?
The information provided does not detail what taking part involves regarding visits, assessments, medication, or follow-up. It focuses on the purpose and eligibility for the study. Typically, studies like this might involve a single visit or a few visits to a research centre to complete the tests described. These tests are likely to include activities that measure your response times and how you perceive touch and time. There is no mention of medication in this study description. The total duration of participation is also not specified.

Common questions
What is the main goal of this study?
The main goal is to better understand how people with schizophrenia perceive time and their own body, hoping to find ways to identify people at risk of psychosis earlier.
What are 'tactile measures'?
Tactile measures are simply tests involving your sense of touch, to see how you react to different sensations.
Will I receive any new treatment in this study?
The information provided suggests this is an observational study focusing on measurements, not a study testing new treatments or medications.
Who can take part in this study?
Adults between 18 and 60 years old who meet specific health and social security criteria can take part.
What if I decide I don't want to be in the study anymore?
You are free to leave the study at any time, for any reason, without it affecting your medical care.
