What this study is about
This study will provide data for evaluating the psychometric characteristics of the tests assessing cognitive flexibility, including their (1) internal consistency, (2) feasibility and tolerability, their (3) convergent and discriminant validity of cognitive and affective constructs such as those introduced to understand mental disorders, and (4) sensitivity (and correspondence) to individual differences. For these tests to be useful in studying clinical conditions, they must show adequate reliability, validity, and sensitivity in large samples of convenience.

Interventions
DIAGNOSTIC_TEST
Computational dissociation of the causes of cognitive rigidity in depression
involves a single testing session with surveys and tasks relevant to the experiment involving behavioral tasks and self-report questions through an online crowd-sourcing platform
Primary outcome measures

Time frame: 1 hour
Relationship of model-based measures of learning from the past and anticipating the future to symptoms of depression, specifically anhedonia
Relationship between environmental volatility and cognitive rigidity
Time frame: 1 hour
Relationship between environmental volatility and model-based measures of cognitive rigidity.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
