Masked stimuli (numbers, letters, textual content) will be displayed on the screen. These stimuli will be difficult to recognize at the start because they will be more masked. Gradually, the stimuli will become easier to recognize.

Your task is to try to recognize the stimulus shown to you as soon as possible. Type the answer in the box at the bottom of the screen.

For the next task, click the button at the bottom of the screen (right arrow) or press ENTER. If your entered answer was correct, the following stimulus will be displayed. Otherwise you will be shown the same stimulus but less masked, until you enter the correct answer. It is not possible to return to the previous item (stimulus).

Your results will be displayed at the end of the task.

This task requires 2 people. The first person is the respondent trying to guess what is in the picture shown. The other person (research leader) is familiar with the content of the stimuli presented and evaluates the respondent's response. If the respondent has correctly guessed the content of the displayed image, the research leader should type "y" ("Y") in the box at the bottom of the screen. All other entered answers are ignored, ie they are considered incorrect.

Masked images will be displayed on the screen. These images will be more masked at the beginning, but will gradually become easier to recognize.

Your task is to try to recognize what is displayed on the screen as soon as possible and tell the research leader.

If you hit the content of the image, the following image will be displayed. Otherwise you will be shown the same image but less masked, until you guess the correct answer.
