A staircase using the QUEST algorithm from Watson & Pelli (1983)

A basic demo of a psychophysics staircase, using orientation discrimination.

This is a recognition test following the encoding test. Participants decide if images were seen before or presented together, in two parts: practice and trial. Based on this paper.

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.

The classic Stroop task.

Triplet task for younger children

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

Basic Choice Reaction Time (CRT) created based on the paradigm used in The Irish Longitudinal Study on Ageing (TILDA)

Participants must click on the start button and are then presented with either the word "YES" or "NO". They must then click either YES or NO to correspond with the word presented onscreen. This allows seperation of the cognitive RT (time taken to start the movement) and the motor RT (time taken to complete the movement)

In this task participants are tested on their iconic memory. Eight random letters (D, F, J, K) are presented in a circle for 100 ms and an arrow points to a letter participants are meant to memorise. This experiment is based on Lu et al. (2005) experiment.
