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

Plugin Description

The cloze plugin displays a text with certain words omitted. Participants are asked to replace the missing words, and are recorded upon clicking a button. Responses can be evaluated and a function is called in case of either differences or incomplete answers, making it possible to inform participants about mistakes before proceeding.

Examples

Several example experiments and plugin demonstrations are available in the /examples folder. After you've downloaded the latest release, 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.

Documentation

Documentation for this plugin is available here.
