This is a classic 'Attentional Blink' Task. Measure temporal limitations in the ability to deploy visual attention.

This is a classic 'Change Blindness' Task. Measure how long it takes participants to spot the difference!

The dot-probe is a classic task used to assess selective attention.

The classic Flanker Task (or Eriksen Flanker Task) is a 'response inhibition' test used to assess participants' ability to suppress responses.

This Inattention and Impulsivity experiment is loosely based on a lab study conducted by Serena Bezdjian, Laura A. Baker, Dora Isabel Lozano, and Adrian Raine in 2009 on twins aged 9 and 10. Reference: Bezdjian et al. (2009)

This tests vigilance, a prolonged state of concentration. Participants must stare at the image of a ticking clock and identify when the second hand jumps more than it should. This example has a jump rate of around 8% and lasts a minute, whereas a full task would jump around 0.5% of the time, and last much longer. Reference: Mackworth (1948)

This spatial orientation task measures the effects of cueing on reaction times to target stimuli. This example requires the participant to press one of two keys when a green 'thumbs up’ appears in the corresponding box. 75% of the time, a green circle will appear in the correct box before the stimulus appears.

A classic sustained attention reaction test (or SART).

View a classic Implicit Association Test: Category sorting task. Categories of images are paired with another category of interest. Differences in accuracy and RT are used to potentially measure implicit bias.

View a classic Implicit Association Test: Category sorting task, measuring strength of association between categories of images and word categories. Differences in accuracy and RT are used to potentially measure implicit bias.

View a classic Implicit Association Test: Category sorting task, measuring strength of association between two sets of word categories. Differences in accuracy and RT are used to potentially measure implicit bias.

View a classic Implicit Association Test, comparing RT and Accuracy in categorising different aged people against positive and negative words. This is potentially a measure of implicit bias towards groups.

View a Classic semantic priming task. Targets are paired with related or neutral primes. The semantic priming effect is the difference in RT and Accuracy a related prime produces.

Name the animal in the picture! Participants are presented with the silhouette of a common animal. They have to type the name of the animal.

Count how many zeros appear in a grid. This is a classic real effort task. A grid of 1s and 0s is shown to the participant. They have to respond with the number of 0s. The grid is shown as an image, to make it more bot proof.

Can you find the cat among the dogs?

Select 'Strongly Agree' on a Likert scale. This is a simple questionnaire.

Choose a colour from the list of words. This is a simple questionnaire.

This keyboard task measures response time and choice response times, which correlate with general intelligence.

This task is used as a measure of reasoning and the ability to 'think outside the box'. Participants are asked to connect 9 dots with four straight lines or fewer, without lifting the pen and without crossing the same dot more than once.
