Components

Components are the building blocks of a screen. PsyCloud ships ~80 of them, each defined by a manifest and identified by a stable componentId and version — for example psycloud.stimulus.text@1.0.0. The SDK helpers (text(), keypress(), …) and Studio palette resolve to these ids.

Snapshot, not exhaustive

The tables below are a representative selection grouped by category. The canonical, complete list lives in the component manifests under src/manifests/core/ and is the source this page will be generated from.

Stimulus & display

Present information to the participant (~26 components).

`componentId`	Purpose
`psycloud.stimulus.text`	Text on the canvas
`psycloud.stimulus.picture`	Display an image
`psycloud.stimulus.sound`	Play audio
`psycloud.stimulus.video`	Play video
`psycloud.stimulus.richtext` / `.html`	Rich / custom-HTML content
`psycloud.stimulus.fixation-cross`	Fixation point
`psycloud.stimulus.blank` / `.background`	Blank screen / background
`psycloud.stimulus.circle` / `.rectangle` / `.arrow`	Shape stimuli
`psycloud.stimulus.draw2d`	2D drawing surface
`psycloud.stimulus.colored-square-array`	Color-grid array (e.g. VWM)
`psycloud.stimulus.random-dot-kinematogram`	Motion (RDK)
`psycloud.stimulus.iat` / `.maxdiff` / `.free-sort`	Task-specific stimuli

Responses & input

Collect participant input (~24 components).

`componentId`	Purpose
`psycloud.response.keypress`	Keyboard key(s)
`psycloud.response.anykey` / `.spacekey`	Any key / spacebar
`psycloud.response.mousepress` / `.click`	Mouse / generic click
`psycloud.response.slider`	Slider input
`psycloud.response.button` / `.continue` / `.confirm`	Button responses
`psycloud.response.prompt`	Text entry
`psycloud.response.form`	Form submission
`psycloud.response.grid-click`	Grid-cell selection
`psycloud.response.timeout`	Non-response (timeout)

Surveys

`componentId`	Purpose
`psycloud.survey.likert`	Likert scale
`psycloud.survey.multichoice`	Multiple choice
`psycloud.survey.vas`	Visual analog scale
`psycloud.survey.survey`	Survey container

(HTML form components — psycloud.html.checkbox, .radio-group, .likert-scale, .textfield, .consent, … — cover DOM-based forms and consent flows.)

Layout & system

`componentId`	Purpose
`psycloud.container.group` / `.grid` / `.radial-layout`	Layout containers
`psycloud.runtime.noop`	No-op step
`psycloud.runtime.state-update`	Update phase state
`psycloud.runtime.data-checkpoint`	Progress checkpoint
`psycloud.compat.jspsychTrial`	jsPsych compatibility wrapper

How SDK helpers map

The typed helpers in the SDKs are thin wrappers over these ids — e.g. text() → psycloud.stimulus.text, image() → psycloud.stimulus.picture, keypress() → psycloud.response.keypress. Using the helpers means you get the right component id, defaults, and validation for free.
