# jspsych-free-sort plugin
|
||||
|
||||
The free-sort plugin displays a collection of images on the screen that the subject can interact with by clicking and dragging. All of the moves that the subject performs are recorded.
|
||||
|
||||
## Dependency
|
||||
|
||||
This plugin requires the jQuery UI library, available at [https://jqueryui.com/](https://jqueryui.com/). You must include the library in the `<head>` section of your experiment page. You can use the [Google-hosted version of the library](https://developers.google.com/speed/libraries/#jquery-ui).
|
||||
The free-sort plugin displays one or more images on the screen that the participant can interact with by clicking and dragging. When the trial starts, the images can be positioned outside or inside the sort area. All images must be moved into the sorting area before the participant can click a button to end the trial. All of the moves that the participant performs are recorded, as well as the final positions of all images. This plugin could be useful when asking participants to position images based on similarity to one another, or to recall image spatial locations.

|
||||
stim_width | numeric | 100 | The width of the images in pixels.

prompt | string | null | This string can contain HTML markup. The intention is that it can be used to provide a reminder about the action the subject is supposed to take (e.g., which key to press).

scale_factor | numeric | 1.5 | How much larger to make the stimulus while moving (1 = no scaling).

sort_area_width | numeric | 800 | The width of the container that participants can move the stimuli in. Stimuli will be constrained to this area.
|
||||
sort_area_shape | string | "ellipse" | The shape of the sorting area, can be "ellipse" or "square".

|
||||
button_label | string | 'Continue' | The text that appears on the button to continue to the next trial.
|

change_border_background_color | boolean | true | If `true`, the sort area border color will change while items are being moved in and out of the sort area, and the background color will change once all items have been moved into the sort area. If `false`, the border will remain black and the background will remain white throughout the trial.
|
||||
border_color_in | string | '#a1d99b' | If `change_border_background_color` is `true`, the sort area border will change to this color when an item is being moved into the sort area, and the background will change to this color when all of the items have been moved into the sort area.
|
||||
border_color_out | string | '#fc9272' | If `change_border_background_color` is `true`, this will be the color of the sort area border when there are one or more items that still need to be moved into the sort area.

border_width | numeric | null | The width in pixels of the border around the sort area. If `null`, the border width will be 3% of the `sort_area_height`.
|
||||
counter_text_unfinished | string | You still need to place %n% item%s% inside the sort area. | Text to display when there are one or more items that still need to be placed in the sort area. If "%n%" is included in the string, it will be replaced with the number of items that still need to be moved inside. If "%s%" is included in the string, a "s" will be included when the number of items remaining is greater than one.
