This experiment demonstrates image/polygons matching as well as opacity on hover. The participant sees four images to choose from. One of the images is randomly chosen and presented at the center of the screen. The participant is required to select

This experiment demonstrates the location randomization of an image.

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.

Animal stroop task - based on Reynvoet et al 2021 and adapted for children In the Animal Stroop tasks, participants are instructed to respond to one piece of relevant information about a stimulus while ignoring the other, often more salient, piece of information. Two animals picture are presented on each trial simultaneously. Participants need to indicate which animal is larger in real life and ignore the size of the image. Two large animals (elephant or bear) coupled with two small animals (rabbit or butterfly) are presented. 1/2 congruent trials: the image of the larger real-life animal (elephant or bear) is larger than the smallest animal (butterfly or rabbit). 1/2 incongruent trials: the image of largest real-life animal is presented smaller than the image of the smallest real-life animal. Stimuli are a total of 16 pairs: 2 small animals x 2 large animals x 2 size (congr|incongr) x 2 sides (left|right) 16 practice trials with feedback; 48 test trials fixation cross 500ms Stimulus on the screen until a response is given. Blank screen 500ms Response: 'f' key for left, 'j' for right Inhibition is measured by an interference score for each task by subtracting the mean response time (RT)/mean accuracy on correct congruent trials from the mean RT/mean accuracy on correct incongruent trials.

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

Guess which shape there are more of: squares or triangles. Better pay attention or you will miss it!

This study aims to explore the theory of double consciousness by investigating how different forms of racial priming affect the cognitive performance of African American students in an end-back matching task.

Open sourced Implicit Association Test (IAT) as a demonstration. This version will run locally in PsychoPy (mouse input) or online (including touchscreen input)

This project accompanies a YouTube tutorial on using eye tracking components in PsychoPy. It includes a local-only .psyexp experiment file demonstrating calibration, validation, gaze-triggered trials using MouseGaze, and custom HDF5 data markers.

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.
