In Task Builder 2, you add functionality to your task by adding Objects. Objects consist of one or more components. You can combine components flexibly within an object to achieve the behaviour you want. You can also use prefabs, which are prefabricated objects with two or more components that fulfil a frequently used function.
This page lists each prefab and the components it contains, and each component and how it works. Browse the list on the side to find the prefab or component you're interested in using.

The audio component allows you to play a single audio file. You can upload the audio file within your component or via the Stimuli tab. For some information about file size and supported formats, have a look at the information at our Technical Checklist.
By default, once you add an audio component to your task, Gorilla will set up an audio initialisation that checks whether participants are able to hear the sound on their device. If you don't want this audio initialisation (for example, if you have several tasks with audio and only need it once), you can turn it off in the Settings tab on the left side in the Task Builder, when you go to 'Subsystems'.
Samples that use this component
Auditory Sentence Predictability Task
Audio
The audio file to play. If you want the audio to change, depending on different screens, you can bind this to a value in your Spreadsheet. If you want to set up a Manipulation in your Experiment Tree, you can bind this to a value for a Manipulation. If you want to play an audio which has previously been written to the Store, you can bind this to a value from your Store.
Play On Start
If set, the audio will start playing automatically at the start of the screen. If it is not set, there are a few ways you can activate the audio, for example, via the Trigger Active component added to other objects of your screen. This way you can trigger audio on some event rather than automatically on start. This is helpful, for example, for an audio feedback scenario.
Advance
If set, advance the screen when the audio finishes playing. When you don't have the Advance option turned on, you can advance the screen using a different component, for example, a Continue Button or just a Click or Keyboard Response.
Always Finish
If set, delay the screen advancing until the audio has finished playing. If you have Advance turned off, you can have Always Finish turned on at the same time, so even though it's the response that advances the screen, not the audio, the audio needs to finish playing before the screen advances.

The Background Audio component allows you to play audio in the background. You can upload the audio file within your component or via the Stimuli tab. Use this component to start or stop the current background audio. Once started, the background audio will continue to play until it is stopped (you don't need to put this on each screen where you want the background audio to play; just on the screen or display where you want it to start). For some information about file size and supported formats, have a look at the information at our Technical Checklist.
Samples that use this component
Digit Span Text Entry (Background Music) (Task Builder 2)
Audio
The audio file to play in the background. If you want the audio to change, depending on different screens, you can bind this to a value in your Spreadsheet. If you want to set up a Manipulation in your Experiment Tree, you can bind this to a value for a Manipulation. If you want to play an audio which has previously been written to the Store, you can bind this to a value from your Store.
Action
Use this setting to decide whether to start or stop the background audio. Please note that the Background Audio doesn't loop automatically, so when the entire file has played, it will just stop (even, if you haven't included the stop setting in your task). If you just want the audio to stop, you don't need to add a file into the 'Audio' setting above.
The Display Receipt component allows you to display the "receipt" from a preceding Gorilla Shopbuilder task. It is bound to a Store Field of the same name used in the Shopbuilder task.

With the hotspot component, you are able to make an invisible area of the screen interactable. It can be used with components like Click Response to generate responses and is useful for overlaying on top of other visual objects. It is helpful if you don't want to make an entire object (for example, text or image) interactable, but only a specific area on the screen, for example, part of an image. In most cases you'll also want to use a hotspot in conjunction with the Overlay component, so that the size and position of the hotspot is set relative to the size and position of the object it's attached to. This can be crucial when participants have different screen sizes or devices which makes an image/text appear bigger/smaller, so that you can keep the hotspot in the same location relative to the part of stimulus that should be interactable.
Sometimes, the order in which you add objects to your screen affects their functioning. Here is an example with the Hotspot component:
You want to have two Objects: Object 1) with a Text component saying 'Click here' and want to use Object 2) with a Hotspot component combined with Click Response component, to make an area where people can click and which will be marked as a response. Now, if you place your Hotspot first on the Objects list, so the most in the background, behind the 'Click here' text, and have the Text object second on the list, so in front of the hotspot, your hotspot won't work. However, it will work if it is put second on the Objects list, so in front of the Text component so that it covers the Text, you can click on the text to respond and the component will work.

Video
The video to display. If you want the video to change, depending on different screens, you can bind this to a value in your Spreadsheet. If you want to set up a Manipulation in your Experiment Tree, you can bind this to a value for a Manipulation. If you want to play a video which has previously been written to the Store, you can bind this to a value from your Store. By default, the video is set to be inactive at the start of the screen, which means that it won't automatically start playing. However, you can use a Trigger - Active component, set to Screen Start, to try and make the video play from screen start.
Controls
Whether or not to enable the standard video controls (allowing the participant to control play, pause, fullscreen mode and others).
Muted
Whether to play the video muted (muted videos will always autoplay). Autoplay means that, when instructed to, Gorilla will try and play the video without any direct action from the participant. Usually, browsers will prevent this from happening on videos that have audio. So, if you had a video unmuted, and set to play from the start or after a fixed amount of time using Trigger - Active, the browser may block it from playing. However, if you have the video set to be muted, then Gorilla triggering the audio to play (rather than the participant) should be allowed
Max Plays
Maximum number of times this video can be played. This does not apply if Controls are active.
Position
Position of the center of the bounding box, relative to the center of the container. You can change the x- and y-coordinates.

The Audio Recording component allows you to record audio from your participants by utilising the participant's microphone. The Audio Recording component is useful when you need to record a participant's voice as part of a task. This is especially useful in language studies. You can record up to 20 minutes for a single recording.
Please note that to start the Audio Recording, you will also need a Trigger - Active component to activate the recording.
By default, once you add an audio recording component to your task, Gorilla will set up a recording initialisation that checks whether participants are able to record themselves on their device. If you don't want this recording initialisation (for example, if you have several tasks with recordings and only need it once), you can turn it off in the Settings tab on the left side in the Task Builder, when you go to 'Subsystems'.
Once you download your audio recordings, these will appear in webm format. If you need them in any other format, any audio processing software will be able to help you with that.
Samples that use this component
File Prefix
A custom prefix to use as part of the filename for the audio recording.
Accessing audio files (in preview mode): When previewing a task, your audio files can be accessed via a URL placed in the metrics. After the preview has finished, download the data and find the URL in this file.
Accessing audio files (in full experiment): When running a full experiment, all of the audio files can be accessed from the 'Manage Experiment Data' button on your Experiment's Data page. The zip folder with all your metrics data will include an 'Uploads' folder, containing all of your audio files.
Getting speech onset times: Sometimes, you need to get the speech onset latency estimates for recorded audio files. The automated tool Chronset could help you doing this for several audio files at once.

The Text Entry components allows a participant to enter text into a text box. This component is similar to the Single Text Entry component. While the latter can submit it's own response, triggering a response during the screen, the former only has it's response triggered at the end of the screen.
Therefore, you can use the Text Entry component if you want multiple text entries on a single screen that can then advanced by a Continue Button press or a Time Limit.
If you want the Text Entry component to auto-snap (i.e. place the flashing cursor in the text entry box) so that participants can start typing on screen start without having to click on the box, you will need to add a Trigger - Active component set on Screen Start.

Allow this Object to be dragged around the screen. For full functionality, there needs to be at least one additional object on the screen with a Dropzone component to create areas that Draggable objects can be dragged onto to generate a response.
The generated response will be a concatenation of the response in the Draggable component and the response in the Dropzone component. For example, if the Draggable has the response 'ItemA' and the Dropzone has the response 'ZoneB', then dragging the Draggable onto the Dropzone will generate a response with the value 'ItemAZoneB'
To allow participants to drag multiple objects or to let them change their mind before submitting their response, consider adding a Continue Button and an Advance - Response screen component.

Find another object on the screen with a name matching our target. If found, start where that object starts, otherwise start in our natural place.
This can be useful if you use it in combination with the Draggable and Dropzone. For example, you could ask a participant to drag and drop a set of items, perhaps to put them into different categories, and you can save their position to the Store. Then, you could redisplay where they placed them by using this component on a different screen.
Location
The location to start this object in.
The Trigger - Active component lets you control the activity state (activated or deactivated) of an object. You can configure this object to become active or be deactivated at the start of the screen, after an amount of time, or when a response is received. This is often used for delaying the onset of an object's functionality. While the Trigger - Enabled component relates to things that the participant can interact with, the Trigger - Active component relates to things that happen to the participant (e.g., audios and videos playing).
Samples that use this component
Auditory Sentence Predictability Task
Tutorials that use this component
Triggering videos to start playing
Triggers
List of triggers, which can change the activity state of the object. For example: Screen Start, Time Elapsed, Click, Response, Response Accuracy, Response Tag, Response Time. For each trigger, you will have several different configurations, but some will be in common. You can decide whether to trigger the activity state of the current object or another one, whether you want it to activated or deactivated and whether you want a time limit for the activation/deactivation.
Control the state (enabled or disabled) of this object. You can configure this object to become enabled or disabled at the start of the screen, after an amount of time, or when a response is received. Often used for controlling whether an object's interactivity can be used. While the Trigger - Active component relates to things that happen to the participant, the Trigger - Enabled component relates to things that the participant can interact with (e.g., keyboard components, buttons, etc.).
Samples that use this component
Triggers
List of triggers, which can enable the object it's applied to. For example: Screen Start, Time Elapsed, Click. For each trigger, you will have several different configurations, but some will be common to all.
By default, Gorilla is listening for responses as soon as the screen starts. On your Screen tab, set the Screen Manager Response Window to 'Manual' and then in your Objects tab use the Trigger - Response Window component to open the response window at a more suitable point in the screen. If a participant tries to respond before the response window is open, you'll still be able to see it in your metrics as 'too early', but it won't count as a genuine response and won't be scored as correct/incorrect or advance the screen, for example. This is useful if you don't want to start counting reaction times while, for example, an image or text is displayed.
Samples that use this component
Triggers
List of triggers, which can open the Response Window of the screen. For example: Screen Start, Time Elapsed, Click. For each trigger, you will have several different configurations, but some will be common to all.
The Trigger - Visible component lets you control the visiblity of this object. You can configure the object to show or hide at the start of the screen, after an amount of time, or when a response is received. It is often used for implementing feedback, but can be handy for showing timed stimuli as well.
At the moment it's not possible to trigger visibility based on the end of an audio or video file but you can achieve this by creating a column in the spreadsheet with the file duration. On the object that you want to trigger the visibility of, you need to add the Trigger - Visible component, add a trigger, and set the trigger to 'Time Elapsed'. In the 'Time' field, you can bind this to the spreadsheet column with the file durations (in milliseconds). 'Target' refers to the object that you want to apply the trigger to - most of the time this will be 'Self' (i.e. the object that you added the component to) but you can choose any object on that screen if you so wish. Under 'Visibility' select 'Visible' (you'd select 'Invisible' if you wanted to hide the object). This should now only show the object after the number of ms specified in your spreadsheet have elapsed.
Samples that use this component
Triggers
List of triggers, which can change the visibility of the object. For example: Screen Start, Time Elapsed, Click, Response, Response Accuracy, Response Tag, Response Time. For each trigger, you will have several different configurations, but some will be in common. You can decide whether to trigger the visibility of the current object or another one, whether you want it to appear or disappear and whether you want a time limit for the appearance/disappearance.

This component controls how the screen advances when a response is received. By default, the screen will advance when the first response is received. This response can be any accuracy. When the Advance - Accuracy component is added to the screen, you can choose to only advance the screen when the first correct or incorrect response is received. In order for this to work, you would also need to add a Scorer component. Alternatively, this component can be used to trigger the screen to advance when timed out by a Time Limit component or when a Continue Button is pressed.
Samples that use this component:
Relational Reasoning (Task Builder 2)
Advance On
The response accuracy to advance the screen on.
The Advance - Response component controls how the screen advances when a response is received. By default, the screen will advance when the first repsonse is received. You can use this component to only advance the screen when a specific response is received. You can directly enter this into the Response field of the component, or you can bind the response to the spreadsheet, if you want the response to vary trial by trial.
Alternatively, the Time Limit component or Click To Continue will continue to advance the screen when using this component.

Use the Branch component to control the flow of screens within a display. You can branch participants based on their response, the accuracy of their response, or the value of a field in the store. The default is for participants to go through each screen of a display sequentially, like a slideshow. But with the Branch component, you can control the flow of screens and send participants to other screens within the display instead. This is useful when you want to branch participants to different feedback screens based on their response.

Use this component to change the difficulty of a task by switching to a different spreadsheet based on a set criteria. You can set conditions for when you would like the difficulty to increase or decrease, reset the accumulated 'score' when the difficulty changes, and whether you would like to preserve the participant's position within the spreadsheet or not.
Samples that use this component:
Memory Intrusion with Change Difficulty (Spreadsheet) (Task Builder 2)
Minimum Trials
Use this to set how many trials a participant should complete before switching to another spreadsheet. Leave blank if Gorilla should start testing the switching conditions straight away and on each trial.
Conditions
An array of conditions to test in order to adjust the difficulty, by making the task harder or easier. You can add multiple conditions.
Value: Which value to use for comparison. This will usually be a field from the store e.g. using the Save Accuracy component to save Correct and Incorrect answers to a field in the store, and then using the name of that field here.
Condition: How to compare the store field to the threshold value. Choose the condition logic from the dropdown menu.
Threshold: The value that is tested according to the condition logic to change the difficulty.
Direction: If the condition is met, choose whether the difficulty should change to Easier or Harder.
Spreadsheets (easier to harder)
All spreadsheets for this task need to be added here, ordered from easiest to hardest.
When Changing Spreadsheet
A list of fields to update when changing spreadsheet. We often want to change difficulty based on accumulated scores, e.g. number of correct answers or percentage correct. When changing to a new difficulty, we often want to reset these values, as they now pertain to the previous difficulty level we were on.
Set Field: Choose which field to update. This will often be the field which stores the score.
To Value: State the value which you would like the field to be set to when changing spreadsheets.
Spreadsheet Mode
When changing spreadsheet, Linked mode will preserve the row index between spreadsheets (so if you're on row 6 of SpreadsheetA, and need to go up to SpreadsheetB, you will jump to row 7 of SpreadsheetB). This is useful if you want to maintain a fixed length of trials, and all your difficulty spreadsheets are the same length. Alternatively, Separate mode will keep each spreadsheet's index separate, so if you're on row 6 of SpreadsheetA and need to go up to SpreadsheetB, you will start on row 1.
Change the difficulty by "Staircasing" a field (or set of fields). Define start values, minimums, and maximums as well as step up and step down values for the fields. Different conditions can be defined for when the field should be adjusted and in which direction.
For example, you might want to adjust the time between two stimuli based on a participant's response time on the previous trial.
Samples that use this component:
Stop Signal Task (Task Builder 2)
Minimum Trials
Use this to set how many trials that this instance of the staircasing component needs to run before the staircasing implements. Leave blank if Gorilla should start testing the staircasing conditions straight away and on each trial.
For example if you want to step up/down based on the combined accuracy of the previous five trials you would set this to '5'. Then, every five trials, the staircase conditions will be tested.
Step Parameters
Specify an array of step parameters with details on how to step them if the staircasing conditions are met. You can add multiple instances of Step Parameters.
Conditions
An array of conditions to test in order to adjust the staircase up or down. You can add multiple conditions.
When Changing Step
List of fields to update when stepping up or down. We often want to change difficulty based on accumulated scores, e.g. number of correct answers or percentage correct. When changing to a new difficulty, we often want to reset these values, as they now pertain to the previously difficulty level we were on. You can add multiple instances of this setting.
This component listens for individual responses and combines them together into a single response. You can set how many responses you would like to collate into a single response, and define the type of responses you would like the component to listen for. For example, if you have a series of Text Button Responses and a Section Time Limit, you will only want the Collate Responses component to listen for the Text Response tags. To advance the screen, a Time Limit or Continue Button (such as with a Click to Continue component) must also be added.
Collating responses is useful for trials where you want the participant to enter a sequence of responses (e.g. Digit Span, Trail Making) and, unlike Compound Responses, only capture the final one when they are finished.
Samples that use this component:
Tutorials that use this component:
Collating Responses (Task Builder 2)
Required Tags
Only responses with the set tags will be combined. All other responses will pass through (and be processed by other screen components normally). If unset, all responses will be combined.
Response Count
How many individual responses should make up a single response. Once the combined response incorporates this many responses, further responses will not be added (but the backspace option can be used to remove responses). If zero or blank, will allow any number of responses to be combined.
Joining Character
When combining responses, will join them using this character (e.g. if using a comma, the responses A and B will be combined as A,B). You can type in the character you want Gorilla to use when separating responses.
Backspace Response
Treat this response as a backspace character, and remove the most recent response from the list. Whenever this response is triggered, instead of that response being added to the collated response, the most recent response is removed. You could trigger this using the backspace key by adding a Keyboard Response Component and choosing the backspace key. Then, set the response of this key, for example 'back', and then set the Backspace Response in the Collate Response component to match this. You could set this up in the same way using clickable images, too, ensuring the click response matches the Backspace Response.
Tag
Tag for the final response that is submitted.
This component will combine individual responses into a single, combined response. You can set how many responses you would like to combine, and define the type of responses you would like the component to listen for. For example, if you have a series of Text Button Responses and a Section Time Limit, you will only want the Compound Responses component to listen for the Text Response tags. Compound Responses, unlike Collate Responses, captures all responses you have defined. Once the Response Count has been reached, by default the screen will automatically advance.
The Compound Response component is useful for trail-making tasks and creating on-screen keyboards, for example.
Samples that use this component:
Sentence Generation Task (Task Builder 2)
Required Tags
Only responses with the set tags will be combined. All other responses will pass through (and be processed by other screen components normally). If unset, all responses will be combined.
Response Length
The maximum number of responses that can be combined together into a single response. Once this maximum is reached, no further responses will be added.
Joining Character
When combining responses, will join them using this character (e.g. if using a comma, the responses A and B will be combined as A,B). You can type in the character you want Gorilla to use when separating responses.
Backspace Response
Treat this response as a backspace character, and remove the most recent response from the list. Whenever this response is triggered, instead of that response being added to the compound response, the most recent response is removed. You could trigger this using the backspace key by adding a Keyboard Response Component and choosing the backspace key. Then, set the response of this key, for example 'back', and then set the Backspace Response in the Compound Response component to match this. You could set this up in the same way using clickable images, too, ensuring the click response matches the Backspace Response.
The Early Exit component allows you to break the normal flow of the task spreadsheet by allowing the task to end immediately when certain criteria are satisifed. For example, this can be used in combination with a Text Button Response, and when participants press this button, they will exit the task and progress to the next Node in the Experiment Tree.
Samples that use this component
Early Exit Conditions
The conditions under which the Early Exit should be triggered.
Criteria

By using the Effort component, participants responses or actions can be collated into a measure of effort. Have a look at the example of the Effort Button in Task Builder 1, which works in the same way. In Task Builder 2, any response mechanism (Keyboard Response, Mouse Button Response, Click Response, etc.) can be used as a measure of effort. Set a threshold for the desired level of effort. When this threshold has been reached, the effort is marked as complete. The response given when effort is satisfed can be used in other components, such as Trigger - Active.
Samples that use this component:
Effort
The number of responses required before the effort is satisfied.
Field
A field in the store that should be used to hold the current effort value. This allows you to use the effort value elsewhere or link it to other components. If unset, the component will store the effort value temporarily only

Return To Start: Whether to always return to the start of this spreadsheet. By default, if we have already performed some rows of the target spreadsheet, we will jump to the next row rather than returning to the start.
Track mouse coordinates throughout the screen.
A possible use case could be that you want to measure how much time participants spent with their mouse on image stimuli that were displayed on the screen. You can find an example of this situation in our Mousetracking tutorial. If you don't record coordinates (see setting below), Gorilla will provide the percentage and the exact time participants spent with their mouse on your object components (e.g. images, videos, buttons, etc.). Samples that use this component
Mousetracking (Task Builder 2)
Record Coordinates
Whether to record a stream of all mouse coordinates in a separate file. This stores X,Y positions every time the mouse moves, and thus generates a lot of data. If you're only interested in which zones the mouse was over, or which quadrants of the screen the mouse was in, then you may not need this.
Use the Increase Progress component to increment participants' progress when a screen is completed, or based on participants' response or response accuracy. The progress can be displayed to participants by using a Progress Bar component in conjuction with this Screen Progress component.
Samples that use this component:
Relational Reasoning with Progress Bar
Tutorials that use this component:
Criteria:
Choose criteria, from the dropdown menu, that participants must satisfy before progress increases. For example, you could choose the criterion to be the amount of correct trials, if you also use the Scorer component in the Screen tab. You could also link it to the total amount of trials by setting the Progress Conditions to 'Always'.
Field
The field to increment for this progress condition.

Use this component to save a variety of measures of accuracy to specific fields in the store. For example, you can save the number or percentage of correct and incorrect responses, or the number of consecutively correct or incorrect responses, as well as the total number of trials. You can then, for example, show participants their accuracy at the end of the task, by binding a Text component to the same field in the store or controlling the flow of the task with Change Difficulty - Staircase.

Attribute: Choose a measure of accuracy from the dropdown list.
Field: Save to a chosen field in the store.
Tag: Set a tag for the stored responses.
The Save Data component can be used to add or update a value on the store when specific criteria are satisfied. This could be based on receiving a specific response, the accuracy of that response or other fields within the store.
For example, this can be used to award points for correct answers, and subtract points for incorrect answers. To award points based on response accuracy, a Scorer component will also be needed.
This component replaces the previous Save Data on Response component.

Criteria
Set the conditions under which the data should save to the store: Always, on a particular Response, on a particular Response Accuracy, or when Match Field is true.
Response: If Response is selected in the Criteria, set the response for the component to listen for. This can be entered directly into the component, or bound to the spreadsheet, a manipulation or the Store.
Accuracy: If Response is selected in the Criteria, determine whether Gorilla should only listen when that response is Correct or Incorrect. If Response Accuracy is selected in the Criteria, determine the accuracy regardless of the specific response received (Any, Correct, Incorrect, or Timed Out).
Filter: Only available when Response or Response Accuracy are selected in the Criteria. Use this toggle to create more complex logic using the additional Field, Condition, and Value settings.
Field: If Match Field is selected in the Criteria, select the field that contains the information you want to evaluate.
Comparison: If Match Field is selected in the Criteria, select the comparison you want to make between the Field and the Value.
Value: If Match Field is selected in the Criteria, specify the Value that you want to compare the Field to based upon the Comparison.
Operation
Select whether the value should be added or subtracted.
Value
Set the value to be added or subtracted. This can be entered directly into the component, bound to the spreadsheet or retrieved from the store.
Field
Save this to a chosen field in the store.
Use this component to save participants' response reaction time to specific fields in the store. You can store the current, average, or total reaction time. These measures can then be displayed to participants by binding a Text component to the field in the store. Also, the reaction time measure in the store can be used in combination with a Branch component or Jump to Row component, for example, to control the flow of the task based on reaction time. Although we save reaction time to your data by default, you can use this component to save participants' reaction times to the Store so that they are available for use elsewhere in your task or Experiment Tree.
Samples that use this component:
Destinations
List of locations to save reaction time measures to.
Attribute: Choose the reaction time measure to save from the dropdown list.
Field: Save this to a chosen field in the store.
Response: Choose the response that you want to save the reaction time of.
Tag: Set a tag for the saved reaction time.
Accuracy: Choose the accuracy for the component to listen for, from the dropdown list.
Using this component, you can save a particular response to the store. This stored response can be retrieved later on within the same task, or within a different task later on in the experiment tree. Responses saved to the store using this component can be shown to participants later on. If there are several responses recorded on one screen, you can save all of them or individual ones, but you will need to match them separately with the Field configuration.

The Section Time Limit component allows you to set a time limit for a section of a task. For example, this could be for a series of screens in a display, or a number of trials in the task.
Set the mode to 'Start' to begin the Section Time Limit. The duration of the time limit will be set here.
On another screen, add a Section Time Limit and set the mode to 'Check'. This will review the remaining time on the Section Time Limit. If the time limit expires, it will emit the set response with the chosen tag. This response can then be used in other screen components, such as Jump to Row or Switch, to control how the task behaves when the time limit expires.
Use the 'Pause' mode to pause the time limit on a screen. The time spent on this screen won't count towards the participant's time in the section.
You can use a Section Countdown component, in conjunction with a Section Time Limit in Check mode, to display the time remaining in the Section Time Limit.
Samples that use this component:
Screen Timelimit Actions
The set of screen timelimit actions to run on this screen. These should be placed in the order you want them to run.
Mode
The Mode of operation for the component. Set to Start for a screen where the Section Timelimit should start running, Pause if you want to pause the timer, Check if you want to check if the timer has expired, and Stop if you want to stop the current section timelimit completely.
Time Limit (ms)
How long the section will last (Start mode only)
Response
The response value generated when the Section Time Limit expires. Other components (such as Jump to Row, Early Exit etc.) can listen for this response, triggering the desired behaviour for a Section Time Limit expiring. (Check mode only)
Tag
The tag value for this response (Check mode only)
Strict
If on, the section time limit will resolve as soon as the time limit expires. Otherwise, it will wait until the end of the current screen (Check mode only)

Initialise a field in the store on screen start. Allows you to give one or more fields in the store a value at the beginning of the screen. This is useful for setting a store field to a starting value before using it in staircasing with the Change Difficulty - Staircase component, for example. You can additionally control the starting value of the field with a spreadsheet or manipulation, for example.

The scorer component is used to record participant responses as correct or incorrect. The accuracy of responses given via Click Response, Keyboard Response and other Response components can be recorded using the Scorer.
The correct answer can be entered directly into the Correct Answer field of the component. If the correct answer changes trial by trial, then the component can be bound to the spreadsheet. The Feedback component relies on information from the Scorer component to present a green tick when correct, or red cross when incorrect.
If you have multiple answers that are considered correct, use the Scorer (Multi) component instead.

Scoring Tutorial (Task Builder 2)
Correct Answer
Correct answer. Responses matching this will be considered correct.
The Scorer (Multi) component allows you define multiple correct answers. This could allow participants to choose one of multiple correct answers, or choose all correct answers presented on a screen. The correct answers can be entered directly into the Correct Answers field, where you can add as many as you want, or bound to the spreadsheet if the correct answers change trial by trial.
The accuracy of responses given via Click Response and other Response components can be recorded using the Scorer (Multi) component.

The Time Limit component allows you to add a time limit to your screen which will automatically advance a participant to the next screen in your display after a set amount of time. This can be used to limit the presentation time of stimuli, or control how long participants have to provide a response. You can show participants how long is left of the time limit by also adding a Countdown component.

The Switch component allows the participant to switch to the corresponding Switch Node Task or Questionnaire in the experiment. You will need to include a Switch component (like this one) or a Switch widget in both the Tasks / Questionnaires tethered to the Switch Node, if you wish participants to be able to switch between the two.
You can set specific criteria in the Switch component, so that participants can only switch when certain conditions are met.

This randomisation component allows you to assign participants to spreadsheets by matching their Public ID. To use this component, the task must have multiple spreadsheets, and you must use a recruitment policy where you define a set a list of Public IDs. For example, Email Shot, Email ID and Supervised policies are ideal policies for this randomisation.

Select a randomised subset of a group of trials. Define a column and a value, that are used to indicate the set of trials to draw from and then a number to indicate the number of trials to select for the subset. For example, if you chose the column 'Display', the value 'trial' and the number 10, the script will collect all of the rows with the value 'trial' in the 'Display' column, shuffle them and then pick 10 and read them back into the spreadsheet. You can select multiple subsets by using the + symbol to add another set of options. Each subset must be contiguous and each subset must be distinct from other subsets.

This component allows multiple players to communicate with each other. Text one player sends via the chat box will appear to players in the same room.
To set this up, create a network data field in which to store the chat data.
Each response the participant gives will create a new line in their data, with the reaction time that their message is sent. The Response column will contain the text of that message.
To see the full conversation so far, look to the Network Store column.
In your Network Store column, you will see something like the following:
[{"speaker":6746720,"message":"text"}]
[{"speaker":6746720,"message":"text"},{"speaker":6746719,"message":"word"},{"speaker":6746720,"message":"text2"}]For each message, first you will see the participant private ID, then, after the word “message” you will see the text the participant entered into the chat box. Messages will be displayed in order they were entered, with the most recent message (the one from the participant that entered the data row) coming last.

This component, when added to an object, allows you to show the object to one of your players, but not the others. This is useful e.g. for response buttons where only one player is supposed to respond, and the other players are supposed to wait.
Note: This component alone doesn't allow one player to advance the screen. You would also need to add a screen component Advance - Multiplayer which allows you to determine who has control over advancing the screen. For example, you would set this component to Player A. Why we need it: As a default, multiplayer tasks will wait for a response from each Player before advancing the screen, therefore if you don't have the Advance - Multiplayer component, the screen will wait for Player B to also press something before the screen continues, and unless you have a continue button or another way to progress the screen for Player B, the Players will get stuck. You want Player A to control advancement so adding this component will ensure that action.
Player
The player to show this object for.
Control whether one player can advance the screen for all players, or whether all players need to complete the screen to advance. This component is added to the Screen.
Required Players
Specify whether all players need to complete to advance ('All') or just one player ('First')
Allow only a specific player to advance the screen. This component is added to the Screen.
