Status of online options¶

The table below shows you the current state of play of PsychoJS. Per feature we list whether it’s:

Built-in Supported via the PsychoPy Builder
Prototype Supported via tutorials or customized experiments that can be cloned and adapted. Kudos to our users for pushing the envelope!
Not supported Supported by PsychoPy, but not yet supported by PsychoJS

Feature	Status	Notes
Stimuli
Dots (RDK)	Prototype	The dots component isn’t yet in PsychoJS. You could use pre-created movies instead- or try a workaround with code components here thanks to Francesco Cabiddu
Images	Built-in	Ensure to use the image extension when referencing images in your experiment e.g. “.png” “.jpg” - this will help avoid “Unknown Resource” errors
Movies	Built-in	Do check mediaFormats
Polygons	Built-in	If using circles online use a “regular” polygon with 100 vertices - rather than using the dropdown “circle” option
Text	Built-in	We recommend using “Text” rather than “TextBox” for static text online - since TextBox is still in beta
Textbox	Built-in	For versions preceding 2022.1 textbox needed a code component with textbox.refresh() in the “Begin Routine” to be used on several trials
Grating	Built-in
	Not supported	Apertures, Envelope Gratings, Noise
Responses
Form	Built-in
Pavlovia Surveys	Built-in
Gyroscope	Prototype	Measures the orientation of tablets and smartphones. Try it out
Eye-tracking	Prototype	Try it out
Keyboard	Built-in
Mouse	Built-in	Mouse components translate to touch responses on touch screens
Slider	Built-in	Use slider and not “rating” for online studies
TextBox	Built-in	see above
Brush	Built-in
Microphone	Built-in	available in 2021.2 onward
	Not supported	Joystick, Button boxes (Cedrus & IO Labs), Button component
Data
CSV files	Built-in	These can easily be imported into analysis software, such as Matlab, R, JAMOVI, or JASP
Log files	Built-in	Low-level logs. These offer detailed information, but are hard to analyze
MongoDB	Built-in	Similar to CSV, but stored in a database instead of files
	Not supported	XLSX
Flow and Logic
Code	Built-in	Insert snippets of programming code, which can be automatically translated from Python to JavaScript
Loops	Built-in	Loops allow randomization and importing condition files.
Staircases	Prototype	Adapt aspects of a trial based on earlier responses of a participant. Try out a “Just Noticeable Difference” staircase via staircase-demo
Multistair	Prototype	Interleave several basic staircases. This is currently possible through interleaving basic stair prototype (note that in this prototype the staircase list is randomly shuffled each time). You can try a Pavlovia demo
QUEST staircases	Prototype	This is currently supported via jsQUEST you can try a demo and access the gitlab project to build on for your own research
External Tools
AMT	Built-in	Amazon Mechanical Turk. See instructions in this forum post
Prolific	Built-in	See instructions at Recruiting with Prolific
Qualtrics	Built-in	There are many guides available for integrating Qualtrics on our forum
Sona	Built-in	See instructions at the Sona Systems website

Thanks go out to Anastasia Carter, Arnon Weinberg, Francesco Cabiddu, Lindsay Santacroce, and Wakefield Carter; they made tutorials and/or demo experiments available that we referenced in the list above.

Anything else we should add to the list above? Built a cool prototype? Please tell us via the PsychoPy Forum.
