Psychomotor Vigilance Task to be run in Pavlovia

In this task participants are required to memorise and recall number series in order. Participants start out with three 3-digit sequences. If participants correctly recall 2 out of 3 three sequences, they progress to 4-digit sequence trials and so on. If participants respond incorrectly on 2/3 trials the experiment terminantes. This experiment is based on the original digit span experiment by Jacobs (1887).

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

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

A demo based on the Glasgow Face Matching task. Used in the study of face perception.

A demo based on the Balloon Analogue Risk Task. Participants pump a balloon and try to cash in a prize before the balloon pops. Generally used as a measure of risk taking and decision making.
