Trial summary

The ability to recognize of being the actors of the behaviour and its consequences, the so-called "Sense of Agency" (SoA), is a crucial component of self-awareness. One key aspect is the distinction from a mere inference about the causality between an act and its consequences and the sense of being the agent of it. Read more about this study

About this study

Official title: Behavioural and Neurofunctional Correlates of the Sense of Agency

The ability to recognize of being the actors of the behaviour and its consequences, the so-called "Sense of Agency" (SoA), is a crucial component of self-awareness. One key aspect is the distinction from a mere inference about the causality between an act and its consequences and the sense of being the agent of it. Despite a large number of behavioural studies, there is unsatisfactory evidence on the functional anatomical underpinnings of the SoA and the distinction between causality and the SoA proper. Here, the investigators use an implicit measurement of the SoA and its modulations during fMRI: the intentional binding phenomenon (IB). The ivestigators also study how the SoA and the ensuing neurophysiological correlates are modulated by the presence of a movement disorders, such as Gilles de la Tourette Syndrome.

What participants receive

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

  • Behavioral and fMRIOther

    Subjects and patients will perform temporal-judgment-tasks (considered an indirect measure of the sense of agency) in an event-related fMRI setting. In the first task, they will hear a sound either caused by a voluntary key press or by the passive displacement of the same finger by the experimenter. Following each trial, subjects will estimate the delay between the finger movement and the subsequent sound, which will be presented at variable latencies after the key press. There will be also control-trials characterized by the active or passive movement with a subsequent sound presented with a delay that excludes causality inferences.

What is being measured

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

  1. BOLD signal changes

    The investigators will measure the changes of the BOLD signal associated with the modification of the sense of agency both in healthy subjects and neurological patients.

    Measured: April 2017 - October 2019

Questions about this trial

What is this clinical trial studying?

An observational study of Motor Activity and Motor Tic Disorders, run by I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio at 1 site in Italy.

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 3 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 5 Dec 2017. 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 Italy. 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?

Results are not available in the source record.

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

Contact Sara Zacchetti (+390266214057, sara.zacchetti@grupposandonato.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BOLD signal changes (time frame: April 2017 - October 2019). 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 5 Dec 2017; AzTrials last refreshed its copy on 7 Nov 2026.
