 This apparatus collects data for psychophysical experiments for deep pressure. A veneer actuator and end effector exert force over a specified area. A load cell coupled with a signal conditioner and controller amplify and record force. The participant presses the mouse button when they feel light touch, deep pressure, and pain. At each button press, the actuator pauses at the participant's threshold. With this apparatus, we can determine the magnitude of force perceived as deep pressure and compare it with other sensations such as touch and pain.
