Mechanistic Interventions and Neuroscience of Dissociation

Participants will attend two intervention sessions per week for a total of 8 sessions. Participants will sit in a chair in a sound-proof booth monitored by a researcher in front of a computer screen (which delivers instructions) and will be fitted with psychophysiology leads and a device strapped around the chest. There will be no explicit tasks or direction given in this intervention. Participants will experience smooth slowly varying breath-like vibration on their sternum. They will receive their assigned intervention for approximately 18 minutes.

Participants will sit in a chair in a sound-proof booth monitored by a researcher in front of a computer screen (which delivers instructions) and will be fitted with psychophysiology leads and a device strapped around the chest. The participant will be asked to focus on their breathing during this intervention. They will receive their assigned intervention for approximately 18 minutes.

Participants will sit in a chair in a sound-proof booth monitored by a researcher in front of a computer screen (which delivers instructions) and will be fitted with psychophysiology leads and a device strapped around the chest. Participants will engage in a period of no-screen time; during this time there will be no outside visual or auditory distractions. There will be no explicit tasks or direction given in this intervention. They will receive their assigned intervention for approximately 18 minutes.
