Recruitment & Eligibility

• Status: Pending
• Sex: All
• Target Recruitment: 300

Inclusion Criteria

4 groups of patients / participants which fulfill following criteria:
- Healthy controls (n = 60)
- ASD patients as diagnosed based on ADOS-2/ADI-R and a clinical assessment by a qualified psychiatrist (n = 60).
- SCZ patients as diagnosed based on a clinical assessment by a qualified psychiatrist (n = 60)
- SAD patients as diagnosed on a clinical assessment by a qualified psychiatrist (n = 60).
- OCD patients as diagnosed on a clinical assessment by a qualified psychiatrist (n = 60).
- Ability to understand the study procedure
- Informed consent: A declaration of informed consent has to be signed and personally dated by the subject.

Exclusion Criteria

- Presence of disorders other than ASD, SCZ, SAD and OCD, which may deteriorate social functioning, motor function or cognitive abilities such as dementia, severe arthritis, drug/alcohol abuse, Alzheimer’s Disease, or stroke. However, because of high co-occurrence rate of conditions such as depressive disorders in ASD, SCZ, SAD and OCD, such disorders will be controlled for in the analyses but will not constitute a hard exclusion criterion. We will, however, attempt to recruit mainly individuals with no comorbidities.
- Inability to remain motionless in the fMRI scanner without involuntary movements providing intolerable artifacts
- Inability to give informed consent
- Claustrophobia
- Pregnancy
- MRI incompatible implants, such as cardiac pacemakers or magnetic objects
- Permanent makeup
- Large tattoos particularly in or near the imaging area
Abandon criteria:
- Occurrence of any exclusion criterion either at the time of recruitment or revealed after/during measurement such as incidental findings in the MRI images
- The patient’s / participant’s decision to abandon the study at any time
- Withdrawal of consent
