Trial summary

Incidental affective states, i.e., affective states can influence decision making and selective attention to threatening information. Acute stress is such an affective state and is a powerful contextual modulator of decision-making processes and selective attention to threat. Read more about this study

About this study

Official title: The Role of Stress Neuromodulators in Decision Making Under Risk

Incidental affective states, i.e., affective states can influence decision making and selective attention to threatening information. Acute stress is such an affective state and is a powerful contextual modulator of decision-making processes and selective attention to threat. In terms of physiological and neurohormonal changes, the stress response has been well characterized: Exposure to stress elicits an array of autonomic, endocrine, and behavioral responses. The physiological stress response is mediated by the hypothalamic-pituitary-adrenal (HPA) axis and the locus coeruleus noradrenergic (LC-NA) system with cortisol and norepinephrine (NE) as their end products. There is compelling evidence that the stress hormones cortisol and NE influence cognitive processes. However, only very few studies so far used pharmacological approaches to specify the role of stress neuromodulators on decision making and selective attention to threat and these studies are hardly comparable due to differences in the experimental design, e.g., the decision making task used. Furthermore, the neural underpinnings of stress effects on decision making and selective attention to threat are uninvestigated so far. The aim of the proposed project is to clarify the role of the major stress neuromodulators, NE and cortisol, in their contribution to different processes related to decision making under risk and selective attention to threat. To this end, combined precise pharmacological stimulation, behavioral modeling, and fMRI methods will be applied to systematically disentangle the effects of stress hormones on risk attitudes and loss aversion as well as their relation to neural correlates of processing subjective value and risk. Using pharmacological manipulation, the influence of noradrenergic and glucocorticoid activity on decision making under risk at the behavioral, computational, and neural level will be investigated. In addition, the influence of noradrenergic and glucocorticoid activity on selective attention to threat at the behavioural and neural level using a dot-probe paradigm with fearful and neutral faces will be examined. Participants are randomly assigned to one of four groups: (A) yohimbine, (B) hydrocortisone, (C) yohimbine and hydrocortisone, or (D) placebo.

What is being measured

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

  1. Risk and loss-aversion, choice consistency

    Behavioural outcome of the decision-making under risk task modeled using prospect theory (PT)

    Measured: 45 minutes

  2. Patch-leaving times

    Behavioural outcome of the decision-making under risk task including a foraging task part using marginal value theory

    Measured: 45 minutes

  3. Attentional bias to fearful faces

    Behavioural outcome of the dot-probe task

    Measured: 12 minutes

  4. Blood-oxygen-level-dependent (BOLD) response

    In both tasks

    Measured: 45 + 12 minutes

Questions about this trial

What is this clinical trial studying?

A study testing "Yohimbine", "Hydrocortisone" and "Yohimbine + Hydrocortisone" in people with Yohimbine and Hydrocortisone, run by Charite University, Berlin, Germany at 1 site in Germany.

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 4 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 15 Mar 2022. 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 Germany. 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?

Risk and loss-aversion, choice consistency (time frame: 45 minutes). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04359147, which also lists 2 linked publications.

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 15 Mar 2022.
