Author: Josh de Leeuw
Latest version: 2.1.0

![jspsych logo](http://www.jspsych.org/7.0/img/jspsych-logo.jpg)

jsPsych is a JavaScript framework for creating behavioral experiments that run in a web browser.

## Plugin Description

The animation plugin displays a sequence of images at a fixed frame rate. The sequence can be looped a specified number of times, and the participant is free to respond at any time during the animation, while recording the time of the response.

## Examples

Several example experiments and plugin demonstrations are available in the `/examples` folder.
After you've downloaded the [latest release](https://github.com/jspsych/jsPsych/releases), double-click on an example HTML file to run it in your web browser, and open it with a programming-friendly text editor to see how it works.

npm package: @jspsych/plugin-audio-button-response
Description: jsPsych plugin for playing an audio file and getting a button response
Author: Kristin Diep
Latest version: 2.1.1

![jspsych logo](http://www.jspsych.org/7.0/img/jspsych-logo.jpg)

jsPsych is a JavaScript framework for creating behavioral experiments that run in a web browser.

## Plugin Description

The audio-button-response plugin plays audio files and records responses generated with a button click. The audio will be played using the WebAudio API, allowing for reasonably precise timing of the playback by measuring it against the WebAudio specific clock. If WebAudio API is not supported by the browser, the files will be played using HTML5 audio.

## Examples

Several example experiments and plugin demonstrations are available in the `/examples` folder.
After you've downloaded the [latest release](https://github.com/jspsych/jsPsych/releases), double-click on an example HTML file to run it in your web browser, and open it with a programming-friendly text editor to see how it works.
