Participants repeatedly choose between options (arms of a bandit) with different and unknown probabilities of reward. This task models exploration versus exploitation trade-offs.

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

A demo based on the Posner Cueing Effect.

A test of working memory, participants see a series of numbers and must remember if this number is the same as the Nth previously.

A demo based on the Corsi blocks task. Tests Spatial memory. Participants must remember the order in which a series of blocks change colour.

2d random dot motion discrimination task on diagonals

A test of global versus local perception based on the Navon paradigm.

In this task participants are required to sort the presented cards based on a rule. The rule is unknown to the participants, however they receive feedback whether their answer was correct. The rule changes after certain amount of trials. This experiment is based on Grant & Berg (1948) experiment.

A demo based on the Eriksen Flanker paradigm. Participants respond to the direction of a central arrow, whilst ignoring distracting flankers.
