Since the first mirror painting experiment by D. Starch in 1910, the mirror has become the most commonly used psychological laboratory instrument for studying motion learning. The experimental method of the instrument is to let a figure be seen through the mirror and draw on the graph with a pen (the mirror painting is thus derived). Because of the reflection through the mirror, compared with the original image, the image in the mirror is upside down and left and right. Therefore, when drawing, the drawing method opposite to the usual up and down stroke tends to appear, which brings certain difficulties to the person who is the first mirror. But through training, it will quickly adapt to the original customary drawing. This experiment is to understand the process of forming the movement skills through a mirror painting practice of a hexagonal star plate.

step
Preparations First, insert the hex star plate into the lower groove and insert it as the mark on the left side. Lower the hanging glass with the inward operation and insert the probe cable plug into the “snap†socket on the lower left side of the box. Plug the power cord into the socket on the right side of the test stand and turn on the power. Turn on the power switch of the timer counter. The timing screen is displayed as “0.000†seconds, the correct number of times and the number of errors are “0â€, and the working mode is selected as “time countingâ€. Turn on the light switch unit power switch and light switch on the right side of the operation box, and the illumination light in the operation box lights up.
The formal experiment sits on the side of the bench and extends the dominant arm into the sleeve measuring mouth. Hold the probe and place the pen on the starting point on the right side of the graph. Announce the instruction: "After I send the 'Start' password, please use the probe to move forward from the starting point along the middle slot of the graphic, and ask that the metal parts on both sides should not be touched. When the probe touches the edge of the slot, the counter counts once, and A warning sounds. You need to correct the route and continue to do it (note that the probe must not leave the probe in the middle of the experiment) until the end point. At this point, it is considered as practice. "Send the "Start" password and press the "Start" on the lower left side of the operation box. "Button, the instrument starts timing and counts the number of errors. After each painting, change the time and number of errors under the timing, and then press the timer counter "Reset" button to prepare the next contact. After many times of practice, until there are no errors for 3 consecutive times, the dominant hand movement skills are considered to be formed. After the formation of the dominant hand skills, repeat the above experiment with a non-dominant hand.
