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.

In this experiment, you will see a set of colored squares. On half of the trials, a cue will direct you to maintain items in either the left or right visual field after a brief delay.

This experiment demonstrates the effect of using the three units "pix", "height" and "norm" on the scaling of images with PsychoJS. Proceed throught the experiment and resize your Browser window while viewing the images in order to see the effect.

Psychomotor Vigilance Task to be run in Pavlovia

At each stage of this follow-up experiment, you will hear two people speaking one after the other. You will not understand what they are saying. However, after carefully listening to each of them, you will indicate which one sounds the most persuasive to you by completing the sentence below. You can listen to each speaker again by right-clicking on the sound icons.
