The classic Stroop task.

The Posner spatial cueing paradigm.

Taalkundig experiment voor groepsreplicatieproject.

Linguistic experiment for group replication project.

A demo to show how to make a large number of images (e.g. grating stimuli) using PsychoPy coder.

This is currently useful for presenting stimuli online that are not currently supported by PsychoJS (e.g. grating stim and noise stim)

part-list cuing8

Norming data for barakeet study.

In this task participants are required to judge whether the presented stimuli are the same or different. The stimuli are presented simultaneously and reaction time is measured. This experiment is based on Pattern Comparison Task (Simultaneous) by Perez et al. (1987).

Balloon Analogue Risk Task (BART)

The experiment: ——

This is a simplified (and prettified) version of the BART task by Lejuez et al (2002). Participants have to blow up a balloon that they know will burst at some point. They ‘earn’ rewards for getting the balloons to be larger, but increase the risk of bursting it, in which case they earn no reward for that balloon. The question is, how many times does someone pump each balloon trying to optimise their rewards.

The measure is designed to quantify individual differences in risk-taking.

Analysing your data: ——

You should filter out data where the balloon burst and measure the number of pumps made for the remaining trials.

Notes: ——

WARNING: This is an advanced demo involving lots of code components

This can be extended to be more similar to the original paper by adding further colours of balloons with different bursting profiles.
