Behavioral lab (K1F-46)

In this lab, there are 9 identical cubicles. In each of them, the distance between monitor and edge of the working space is 75 cm in general. Chin rests are available as well. However, on cubicle (K1F46-C) is equipped with an eye-tracking system, so it should not be used for behavioral experiments.

How to use the lab

There are several steps to take before you start running your experiment in this lab.

• Turn on the main computer and log in to the proefleider account. On the desktop, you will find the icons to turn on all cubicle computers, turn off all cubicle computers, and the Sync button, with which you can sync any newly gathered data to the main disk Cerberus.
• Use the icon on the main computer to turn on all cubicle computers.
• Turn on the lights in the cubicles with the black device attached to the far wall (next to cubicle C). Simply press the on-button once to dimly light the cubicles.
• Make sure participants are seated with their head facing the middle of the screen: Make sure the chinrest is at its highest, approximately 32 cm from the top of its base to the bottom of the chinrest itself. Make sure to tell participants not to change the height of the chinrest, just to adjust the chair. Repeat this to everyone, as they tend to do it a lot.
• If your experiment contains colours it is advisable to calibrate the monitors in the cubicles. To do this, use the Lacie BluEye device that is stored in the bookcase in the corner. Hang the device over the screen such that it's measuring pad is touching the middle of the screen. Open the Lacie BluEye programme from the Start Menu and press 'Calibration'. Move the window around such that the device is covering the black circle that is presented on the screen. To start calibration, press 'next' in the lower right corner until the button says 'start'. Click that, and wait for several minutes while the device measures the colour intensity on the screen. After it is done, compare the measured colours to the saved calibration settings (takes around 30 seconds). After that, save the report in the calibration reports folder on the desktop, and quit. Attention: calibration works best after the screen has warmed up fully after 30 minutes. Therefore, make sure to arrive in the lab well before your first participant is coming.
• Now that the computer is fully prepared, you can start running your experiment. Experiments that are saved to Cerberus, the shared network disk, are automatically transferred to all cubicles upon synchronisation. If you need only one cubicle, you can manually save the experiment to that computer and retrieve the data with a USB.

Facilities

Below find information regarding all devices used in the lab. If you need something that is not in the list, ask the Helpdesk whether they have it in store.

• Computers - K1F-46
• Software - K1F-46
• Monitors - K1F-46
• Headphones - K1F-46
• Sound Card - K1F-46
• Miscellaneous - K1F-46

In case you need something not mentioned above, please contact the helpdesk and check whether they can provide it.

Also, let the Lab coordinator or the research assistant of the respective lab know if you have to change some settings (e.g. monitor contrast, chin rest, etc...) for your experiments, so that the changes can be set again to default for other experiments. In best case, you leave the lab in the same state as you entered it.
