The Functional Anatomy of Personality Trait Knowledge: An fMRI Study
NCT00095407 · View on ClinicalTrials.gov ↗
Study Summary
This study will identify the regions of the brain that are involved in personality trait knowledge-that is, what a person knows about aspects of personality such as "generous," "honest," and others. It will also examine brain areas relating to a person's knowledge of how likeable those personality traits are, being familiar with the traits, and the degree of associating such traits with one's self. There has not been any previous study, through modern imaging techniques, on the location of the brain and the concepts of personality traits. Patients ages 21 to 65 who are in good health, are right handed, and native speakers of English may be eligible for this study. Pregnant women are not eligible. There will be 200 participants involved in pencil-and-paper or computer tasks. Also, there will be three functional magnetic resonance imaging (fMRI) experiments with 32 participants. Patients may participate in up to three fMRI experiments. Patients will be recruited through NIH's Normal Control Database. They would need to have had a neuroexamination conducted by an NIH doctor within the last year. Patients will be interviewed for any medical, neurological, or psychological condition that would make it difficult to read the fMRI results. Depending on the studies that patients take part in, they will have different questionnaires to complete. They may also perform a computerized test that measures word associations. These tests will take about 1 to 2 hours. The technique of MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. During the initial MRI scan, patients will lie still on a table that will slide into the enclosed tunnel of the scanner. They will be in the scanner not longer than 2 hours. During the procedure, they may be asked to lie as still as possible for up to 1 hour at a time. As the scanner takes pictures, patients will hear knocking or beeping sounds, and they will wear earplugs to reduce the noise. Patients will

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00095407
The ClinicalTrials.gov registry entry for NCT00095407 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 190 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Healthy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00095407 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
