Recognition memory task - encoding and retrieval tasks with 10 min delay period between tasks

The numerical Stroop (Henik and Tzelgov, 1982).

Basic JND orientation discrimination demo

A demo based on Greenberg & Waldman (1993) Test of Variables of Attention.

This experiment is designed to measure participants' forwards, backwards, and sequential digit spans. It uses visual presentation. Sequence length increases every two trials. If participants make an error on both trials of the same length, they move onto the next trial.

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

A demo based on the Lexical Decision Task. Participants judge if words are real words or non words as fast and accurately as possible.

An example of a visual search task. Participants must search for the letter T amongst distractor letters.

Dot-probe task with nicotine images, the following project includes two type of nicotine stimuli: primary stimuli and secondary stimuli, each one containing a total of 12 pair of images repeated 4 times in a random way (48 trials per stimuli type). Between the primary and secondary stimuli there is a 2 minutes pause to let the subject recover its attention. There is a random loop to allow the primary and secondary stimuli to always be selected in a different random order

This task shows you the drag and drop capabilities of PsychoPy and PsychoJS. The demonstration uses a drag and drop puzzle game. The task requires you to drag and drop the black and white pieces into the empty square.

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.

A basic mental rotation task.

A demo based on the Posner Cueing Effect.
