In this task participants are required to memorise and recall number series in order. Participants start out with three 3-digit sequences. If participants correctly recall 2 out of 3 three sequences, they progress to 4-digit sequence trials and so on. If participants respond incorrectly on 2/3 trials the experiment terminantes. This experiment is based on the original digit span experiment by Jacobs (1887).

In this task participants are required to memorise a sequence of square locations. Square position presentation is interrupted by symmetry trails. In symmetry trials participants are required to judge whether the presented picture is vertically symmetrical. Square presentation and symmetry trials are repeated until participants are asked to recall all square locations in sequential order. This experiment is based on Kane et al. (2004) experiment.

This is a demo to show how one can use slider position to change the opacity of an image (in this case: a lightbulb).

At each stage of this follow-up experiment, you will hear two people speaking one after the other. You will not understand what they are saying. However, after carefully listening to each of them, you will indicate which one sounds the most persuasive to you by completing the sentence below. You can listen to each speaker again by right-clicking on the sound icons.

This experiment demonstrates a way to create a timer that resets whenever the participant moves their mouse. The following routine starts if the participant moves their mouse for less than 2 seconds.

This experiment shows how to get the highest rating from multiple routines in a loop.

This experiment demonstrates image scaling depending on spreadsheet conditions.

This example shows a button that changes colors with each click (toggling between two colors). It takes into consideration multiply clicks on long presses.

This experiment demonstrates image/polygons matching as well as opacity on hover. The participant sees four images to choose from. One of the images is randomly chosen and presented at the center of the screen. The participant is required to select

This experiment demonstrates the location randomization of an image.

This example demonstrates a combination of continuous and categorial sliders in the same routine.
