Experiment Instructions:
At the start of each trial, E-Prime triggers Chronos to temporarily block the participant’s visual and auditory perception with the spectacle shutter lenses and white noise from the earphones while the experimenter uses an air pump to change the model to the desired pressure. When participants vision and hearing are restored, they will be presented with a life-sized computer-generated human likeness image projected onto a screen representing one of the eight different simulated patients. After considering the image for 5 seconds, an auditory tone will then signal Chronos to trigger time-synchronized data collection of a tri-axial accelerometer attached to the dorsum of the hand to measure kinematic data and a force sensor resistor on the model to record the force-time curves. The accelerometer and force sensor will be connected to the data acquisition interface CED Power 1401 and a CED 1902 amplifier. The accelerometer and force data are recorded in the sweep-based data acquisition software Signal (Version 7). After the thrust is given, Chronos will trigger the data recording in Signal to stop and reset for the next trial.

Experiment Description:
Examining Visual Perception of Patient Attributes and Tactile Perception of Pressure Modulation of Spinal Manipulation Dose Characteristics
 
Participants will be fitted with visual occlusion spectacles and earphones. The experimenter will initiate the experiment which will randomize the combination of pressure and visual image. Participants will complete 6 trials in a randomized order following each of 8 visuals and 3 pressures for a total of 144 trials. 

 
The objective of this study is to explore which sense of perception clinicians dominantly use to modulate spinal manipulation when both tactile and prior visual information are present. Licensed chiropractic clinicians will be delivering spinal manipulative thrusts to a low-fidelity model. We are attempting to determine which perception is more dominant when incongruent visual and tactical information are presented.
