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 basic tutorial of how to use the button component in PsychoPy version 2021.2.1

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).

In this task participants are required to write down as many words as possible beginning with letters "S" and "C". This experiment is a short version of Thurstone & Thurstone (1938) Chicago word fluency test.
