In this task participants are required to respond to all letter stimuli except from letter X (by pressing space). This task is based on Conners (2000) Continuous Performance Test.

Working memory tests on JavaScript (digit span, operation span, visual array, spatial span)

Data collected for my dissertation Experiment 1. All data collected here is either control participants or ADHD (off) medication. Completed in 2025.

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).

Working With Spatial Units

One of the key advantages of PsychoPy over many other experiment-building software packages is that stimuli can be described in a wide variety of real-world, device-independent units. In most other systems you provide the stimuli at a fixed size and location in pixels, or percentage of the screen, and then have to calculate how many cm or degrees of visual angle that was. In PsychoPy, after providing information about your monitor, via the Monitor Center, you can simply specify your stimulus in the unit of your choice and allow PsychoPy to calculate the appropriate pixel size for you.

However, understanding what exactly these different units mean can be confusing at first, so this demo provides a visual example of how a square will look at different sizes in different units.

In this task participants are required to write down as many words as possible beginning with letters "S" and "C". This experiment is a short version of Thurstone & Thurstone (1938) Chicago word fluency test.

The Simple Reaction Time Task (Deary & Liewald, 2011)

Sustained Attention to Response Time Task (SART)

This SART task is modeled on the framework used in The Irish Longitudinal Study on Ageing (TILDA)

Participants must press a button (mouse or onscreen) in response to a series of digits and withold responses on the number 3)

Each digit appears for 300ms, with an interval of 800ms between digits. The cycle of digits 1–9 is repeated 23 times, giving a total of 207 trials. The task lasts approximately for 4min
