Airstim device

This study will use a novel dental startle UCS previously described by Seligman et al. [23 ]. This stimulus is a 60 psi air puff that is delivered to a maxillary anterior tooth for 100ms through an individualized dental mouthpiece. The mouthpiece will be fabricated in visit 1 using 3 M™ STD Vinyl Polysiloxane Express Putty. The constructed mouthpiece will be used during the experimental task for all study sessions. The puff of air will be delivered to the mouthpiece with a 3/16 inch wide tubing that will receive pressurized air from a California Air Tools 8010 Steel Tank Air Compressor through an AIRSTIM device (San Diego Instruments, San Diego, California, USA). Participants will be told that the mouthpiece will allow them to experience the diverse sensations that humans can have on the alien planet.

The UCS is this study will be the same employed by Seligman et al. [29 ], a 60 psi air puff delivered to a maxillary anterior tooth for 100ms through an personalized dental mouthpiece, fabricated with 3 M™ STD Vinyl Polysiloxane Express Putty. The air puff will reach the mouthpiece through 3/16 inch tubing connected to a California Air Tools 8010 Steel Tank Air Compressor via an AIRSTIM device (San Diego Instruments, San Diego, California, USA). Prior to the experimental task, participants will be informed that the mouthpiece will allow them to experience different sensations on the alien planet. Participants will wear the mouthpiece throughout the experimental task.

The UCS will be a 100 ms 60 psi air puff delivered via a fitted mouthpiece, constructed with 3 M™ STD Vinyl Polysiloxane Express Putty, connected to a California Air Tools 8010 Steel Tank Air Compressor via an AIRSTIM device (San Diego Instruments, San Diego, California, USA) (see Fig. 3). Participants will be told the mouthpiece will help them to experience common sensations on the planet.Fig. 3
