Welcome to the Great British Intelligence Test!

This series of cognitive tests – the Cognitron Challenge – is brought to you by Imperial College London.

You will be asked to complete a series of 13 short tests lasting between approximately 1 and 3 minutes each that are designed to push your planning, reasoning, working memory and attentional abilities to the limit.

The tasks will be presented alongside questionnaires that are analysed together with the cognitive scores. Once you have completed them, you will receive a summary containing personalised feedback on how you performed this time and how your performance has changed since the last time you took the test.

Scientists at Imperial College London will use these data to paint a detailed picture of how people are adjusting to the new and evolving challenges of everyday life as the world moves on from the COVID-19 pandemic, including how factors like work, sleep and lifestyle impact on cognition and psychological wellbeing. The results will be reported in scientific research articles.

The challenge and questionnaire should take about 50 minutes. You can take a break part way through if you need to. If for some reason the test stops part way through, for example, due to a loss of internet connection, then clicking refresh will continue from where you stopped. If you are using a laptop with a touch screen please do not use the touch screen to play the tasks. Touchscreens on mobile devices are fine to use.
