Hi all,

We are conducting an academic study about grouping items by dragging items in a box as you refer to the reference image on the left. There are six practice tasks, and six main tasks. The experiment takes about 30 minutes. Prerequisites are described below.

1. In order to run the experiment, you must have at least 800x600 resolution of a monitor.

2. You must distinguish colors.

3. You must be 18 years of age or older.

4. Before the main tasks, you will be asked to enter your age, gender, and occupation. We also ask the resolution of your monitor display (e.g. 1024 x 768). Choose the closest number if you cannot find the exact number. In order to proceed, you need to provide this information.

We pay you $0.50 for completing this study and $1.00 if all answers for the main task are completed. Also, $0.10 for each correct main answer.
You will first confirm the consent form and then begin a color blind test.
For those who do not pass the color blind test, the system will not proceed to the practice tasks and there will be no payments.
For those who do not pass the practice tasks, the system will not proceed to the main tasks and there will be no payments.
Only those who pass the practice tasks may proceed to the main tasks.
After you successfully finish six main tasks, you will receive a 'code' to paste into the box below to receive credit for completing the tasks.
If you have already finished the experiment and submitted the code after you accepted the HIT, do not continue. We only pay for your first participation.
While you perform the tasks, keep on proceeding to the next pages. Do not refresh/reopen your web page or press the back button on the browser.
You are to refer to the image at the left as a reference that corresponds to the phrases in the box at the right. Drag and drop the items(phrases) only in the box.
Depending on the network bandwidth, it sometimes takes time to load the items in the right box. Please wait until you see a list of phrases in the right box.

Mainly, I've pasted what's described on the first page and hope people who are interested in these kinds of task join in!
