# jspsych-survey-multi-picture plugin
|
||||
|
||||
The survey-multi-picture plugin displays a set of questions with multiple picture response fields. The subject selects a single answer.
|
||||
|
||||
## Parameters
|
||||
|
||||
This table lists the parameters associated with this plugin. Parameters with a default value of *undefined* must be specified. Other parameters can be left unspecified if the default value is acceptable.
|
||||
|
||||
Parameter | Type | Default Value | Description
|
||||
----------|------|---------------|------------
|
||||
questions | array | *undefined* | An array of strings. The strings are the prompts/questions that will be associated with a group of options (images). All questions will get presented on the same page (trial).
|
||||
options | array | *undefined* | An array of arrays of objects containing url key and label key(label is optional). The innermost arrays contain a set of options to display for an individual question. The length of the outer array should be the same as the number of questions.
|
||||
horizontal | boolean | false | If true, then questions are centered and options are displayed horizontally.
|
||||
preamble | string | empty string | HTML formatted string to display at the top of the page above all the questions.
|
||||
|
||||
## Data Generated
|
||||
|
||||
In addition to the [default data collected by all plugins](overview#datacollectedbyplugins), this plugin collects the following data for each trial.
|
||||
|
||||
Name | Type | Value
|
||||
-----|------|------
|
||||
responses | JSON string | A string in JSON format containing the response for each question. The encoded object will have a separate variable for the response to each question, with the first question in the trial being recorded in `Q0`, the second in `Q1`, and so on. The responses are recorded as the image url for the picture clicked on.
|
||||
rt | numeric | The response time in milliseconds for the subject to make a response. The time is measured from when the questions first appear on the screen until the subject's response.
|
||||
|
||||
## Examples
|
||||
|
||||
#### Basic example with multiple questions on a page.
|
||||
|
||||
```javascript
|
||||
// defining groups of questions that will go together.
|
||||
var page_1_questions = ["I like vegetables.", "I like fruit."];
|
||||
|
||||
// definiting two different response scales that can be used.
|
||||
var page_1_options = [{url: "http://www.thetechconnectioninc.com/assets/img/Twitter.png", label: "twitter"}, {url: "http://www.freeiconspng.com/uploads/facebook-logo-png-20.png", label: "facebook"}];
|
||||
var page_2_options = [{url: "http://www.gameswithwords.org/WhichEnglish/images/1_1.jpg", label: "dog chase cat"}, {url: "http://www.gameswithwords.org/WhichEnglish/images/1_2.jpg", label: "cat chase dog"}];
|
||||
|
||||
var multi_picture_block = {
|
||||
type: 'survey-multi-picture',
|
||||
questions: page_1_questions,
|
||||
options: [page_1_options, page_2_options], // need one scale for every question on a page

|
||||
type: 'survey-multi-picture',
|
||||
questions: page_1_questions,
|
||||
options: [page_1_options, page_2_options], // need one scale for every question on a page
|
||||
horizontal: true // centers questions and makes options display horizontally
|
||||
};
|
||||
|
||||
jsPsych.init({
|
