The purpose of this study is to learn more about human time perception and the factors that pertain to it. Specifically, I am interested in the affects of music on time perception.

This demo is just the tutorial demo on jsPsych website. Highly recommended to go through this demo (instructions here) before moving to others.

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).

Mcgurk effect

In this task participants are required to judge whether there are more dots on the left or right side. This experiment is based on Damos and Gibb (1986) experiment.

In this task participants are required to sort the presented cards based on a rule. The rule is unknown to the participants, however they receive feedback whether their answer was correct. The rule changes after certain amount of trials. This experiment is based on Grant & Berg (1948) experiment.

A staircase using the QUEST algorithm from Watson & Pelli (1983)

This experiment is designed to measure participants' forwards, backwards, and sequential digit spans. It uses visual presentation. Sequence length increases every two trials. If participants make an error on both trials of the same length, they move onto the next trial.

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.
