5.Yerkes selector/Multi selector/Yerkes selectorH18409

This instrument is used for thinking experiments and can measure the subjects' ability to grasp the formation process and ability of various simple and complex spatial position concepts. It can also understand the subjects' ability to analyze and summarize problems.

1、 Composition:

1. One participant consists of 12 buttons and 12 indicator lights.

The main test team consists of 24 buttons and 36 indicator lights, of which 12 buttons and 12 indicator lights are set regularly; There are also 12 buttons and 12 indicator lights for participants to choose from for setting; The other 12 indicator lights are displayed after the test button is pressed. The power switch and the reset button of the whole machine are also on the main test side. During the experiment, the experimenter sets the selection positions and rules for the subjects according to certain principles, and the subjects' buttons are connected to the experimenter's light and sound as the conceptual positions for setting.

2. There is a screen in the middle, and the subjects cannot see the main subject's operation.

2、 Usage:

1. Open the upper cover, align the two holes in front of the cover with the two pins on the panel, insert them into the panel as a screen.

2. Plug in the power supply (~220V) and sit on both sides of the screen for the main test and the subjects.

3. The experimenter determines that the subjects need to form a spatial concept, that is, the sound is connected to a button that conforms to a certain spatial position relationship, and designs several specific schemes according to certain principles (refer to the examples in the appendix).

4. The experimenter presses the "Set Position for Subject Selection" button, and the subject indicator light lights up. The experimenter then presses another "Rule Setting" button to select the position connected to the sound for the set concept position.

5. Participants will select a button from the illuminated buttons that is connected to the sound and remember its location.

6. After multiple attempts, the subjects. Press the correct button three times in a row and state the principle of selection correctly. Participants should also explain how they have mastered this principle.

Note that the left-right relationship between the subject and the experimenter is opposite .

At the end of an experiment, press the reset button to reset the entire machine, turn off all indicator lights, and start a new experiment.
