About this study

Official title: The Effects of Vasopressin on Attention Control: An Eye-tracking Study

The main aim of the present study is to investigate whether intranasal vasopressin (20IU) could influence attention control in a social-emotional saccade/antisaccade eye-tracking paradigm.

Read the detailed description

A number of previous studies have reported vasopressin's effect on human social behavior and social cognition, although it remains unclear whether vasopressin could modulate attention allocation including stimulus-driven bottom-up control and goal-directed top-down control. In the current randomized, between-subject, placebo controlled study, 89 healthy male subjects will be recruited and receive either vasopressin (20 IU) or placebo control administered intranasally. 45 minutes after treatment subjects will be required to complete a social-emotional saccade /antisaccade eye-tracking paradigm. The paradigm uses social (happy, sad, angry, fear, and neutral faces) as well as non-social (oval shapes) stimuli to explore social- and emotion-specific effects of vasopressin.

What is being measured

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

  1. Effect of vasopressin administration on saccade/antisaccade latencies towards social (facial) versus non-social (shape) stimuli

    Comparison between social-specific saccade/antisaccade latencies (in milliseconds) between the vasopressin and placebo treatment conditions

    Measured: 45 minutes - 100 minutes after treatment

  2. Effect of vasopressin administration on error rates of saccade/antisaccade for social (facial) versus non-social (shape) stimuli

    Comparison between social-specific error rates of saccade/antisaccade between the vasopressin and placebo treatment conditions

    Measured: 45 minutes - 100 minutes after treatment

Secondary outcomes (2)
  1. Emotion-specific effects of vasopressin administration on saccade/antisaccade latencies towards the separate facial emotions

    Comparison between emotion-specific saccade/antisaccade latencies (in milliseconds) between the vasopressin and placebo treatment conditions

    Measured: 45 minutes - 100 minutes after treatment

  2. Emotion-specific effects of vasopressin administration on saccade/antisaccade error rates for the separate facial emotions

    Comparison between emotion-specific saccade/antisaccade error rates between the vasopressin and placebo treatment conditions

    Measured: 45 minutes - 100 minutes after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Vasopressin in people with Healthy, run by University of Electronic Science and Technology of China at 1 site in China.

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 2 inclusion and 5 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 7 Jan 2021. 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 China. 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. Some participants in this study may receive a placebo. 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?

Effect of vasopressin administration on saccade/antisaccade latencies towards social (facial) versus non-social (shape) stimuli (time frame: 45 minutes - 100 minutes after treatment). 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 7 Jan 2021.
