This is a modified version of the popular Go/Nogo paradigm based on the paper by Liebrand et al. (2017) FrontNeurosci, 11, 204. The task aims to measure proactive inhibition. In this version, response feedback has been added.

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).

This experiment runs a working memory task similar to the distractor-based change detection task of Vogel Machizawa (2005) (see also Lenaert et al., 2016). Colored targets are shown in left & right visual field, attention is directed using a cue. Distractors can be presented in addition to targets.

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 is an update to Topor’s implementation of the PST by Frank, Woroch and Curran (2005), made to run online. See https://doi.org/10.1016/j.brs.2022.02.009 for details of other modifications made for offline version and carried through to here.

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.

A learning task based on the reinforcement learning model. The current version is based on the paper by Frank, Woroch and Curran. (2005). Neuron, 47(4), 495-501.
