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.

This project includes the Mooney Faces task, Closure Objects task, Glasgow Face Matching Test, two perception tasks (chimera sets), two facial emotion recognition tasks, the Fantie Cartoon task, and two Identification Threshold tasks.

This is a simple Lexical decision task. A fixation cross will be displayed in the centre of the screen. Following this 2 text stimuli will then appear, and the participant will have to respond if they are words or non words pressing ‘w’ if they are both words or ‘n’ if one or more is not a real word. This will be repeated 36 times for the main trial. Reaction time and accuracy will be recorded, and congruent and incongruent pairs will be compared.

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.

The classic Stroop task.

add / remove stimuli as accuracy increases / decreases

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

The Attention Network Task (Fan et al., 2002).

This experiment demonstrates how to create a rating slider that moves only when its marker is selected. Simply selecting other areas on the slider won't work.

This is a stroop task with 60 congruent and 60 incongruent trials. There are 4 colors (red, green, blue, purple). There is a practice trial before the actual task (16 trials).

The purpose is the test which kind of emotion affects memory Using images with relative music for test memory
