Study 2 - EGG - Methods

Information

Enrollment

Participants will sign up for lab session slots at least 48 hours ahead of time to ensure ability to consent and complete home session. We will set the SONA to reflect the 48 hour rule as well as instruct participants that they must complete the online session before their scheduled lab session.

Consent

The researcher will email the participant the consent form to review and sign electronically. Any questions will be answered at this time. We will direct female participants to wear a sports bra and a comfortable t-shirt. We will mention that we have a hospital gown if they prefer. We will also mention that it might be a male experimenter, so for all participants to look at the diagram and be sure they are comfortable (female experimenter can be available if necessary). We will also ask male participants if they are comfortable shaving any chest/stomach hair for the session and will send them a photo demonstrating the regions involved. We will also tell participants that their response time will be monitored, so to please read and respond carefully to all surveys.
