A condition can include visual stimuli consisting of target or non-target stimulus elements.
o The stimulus can be added to a condition as a precue, warning, or imperative stimulus. The precue and warning are shown before the recording starts. The imperative stimulus is shown when the recording starts.
* Create Stimulus
o Right-click on Stimuli in the left window experiment tree > Create New.
o The following window is displayed: Type a 3 letter ID and a description and click OK.
To Create/Add elements to a stimulus:
o Do the following without closing the previous window for creating a new stimulus by clicking '+'.
o Otherwise, after creating the stimulus, to come back to the above window, right click on the stimulus > Add elements.
o In both cases, the following window is displayed.
o To create and add new elements, click '+'.
o Refer 'stimulus elements' to set the properties and click 'OK'.
o The new element is added to the master list. You can add multiple elements to the list by repetitively clicking '+'.
o To add one or more elements to the stimulus, select a single element or choose multiple elements using 'shift' or 'ctrl' keys with the mouse/pen and click add.
To remove an element from the stimulus:
o To remove an element from the stimulus, select the element in the 'Stimulus Elements' list of the Stimulus properties and click 'X'. This will not permanently delete the element. It will still be retained in the Master list.
o You can also remove an element from an existing stimulus by navigating to the stimulus elements on the left window experiment tree, right click the element > remove from stimulus. This will not permanently delete the element. It will still be retained in the Master list.
o To permanently remove an element for the user, go to the master list by clicking '+' from the stimulus properties window, select the element and click 'X'. You can also navigate to that particular element under the elements on the left window experiment tree, right click and click 'delete'.
To add stimuli to conditions, refer to creating new conditions.
o Select the stimulus from the left tree window > Right click on the stimulus > Properties.
o All the elements that have been previously added to the stimulus are listed in the 'Stimulus Elements' window.
o The Available Targets list shows all the elements from the above list that are defined as targets (To check whether an element is defined as a target select the element > right click > properties > This element will be a target).
o These target elements can be sequenced in a particular order for a stimulus by adding them to the 'target use/sequence' list using -> arrow to add a single element and the ->> arrow to append all the elements from the available targets list to the end of the target sequence list.
If you need to change the sequence after adding the elements use the up and down arrows.
If an element has to be moved back from the target use/sequence list use the <- for moving an element that is selected and <<- arrow to move all the elements back.
o NOTE: You can put the targets in a sequence to form your own patterns. In the target use list, you can repeat any element, by adding it again from the available targets list.
o For example, in the above window, the elements HOM, TO1,TO2, TO3...etc are added repeatedly in a particular order HOM, TO1, HOM, TO4, HOM, TO6, HOM....to create a pattern.
o When the experiment is run, the targets HOM, TO1, TO2... are displayed and the user has to hit the targets from Home to target 1, then back to home, Home to target 4, back to the Home and so forth.
NOTE: Target Use/Sequence may differ per Stimulus and Condition.
Featureso View data: The stimuli data can be viewed in a text file. It shows the x, y and z coordinates of the elements in an order. Select stimulus > right click > view data.
o Chart data: This chart shows the positioning of the elements on the x and y axis, X-Z axis, Y-Z axis, X,Y & Z vs sample numbers.
uluso Test in Recording window: To view the stimulus on the recording screen right click on the stimulus > Test in recording window. This feature is very handy to see how a stimulus will look on the screen before it is added to a condition.
o To stop the test click 'STOP' on the main task bar of the program or hit 'ESC' key on the keyboard.
o NOTE: If you want to see the stimulus in the recording window in real size, set this option: Main tool bar > Settings > Select input device > Tablet/mouse mapping > 'Recording window' and 'proportional'.
When stimuli have been created, they can be used as a warning, precue, or imperative stimulus.
o Right click on the condition you want to add the stimulus to > properties > stimuli.
1. Menu Bar: Tree Action -> Stimuli -> Stimulus -> Properties
2. Left Window: Right-click Stimulus -> Properties
3. Condition Properties -> Stimuli -> Warning Stimulus -> Create New / Properties
4. Condition Properties -> Stimuli -> Precue Stimulus -> Create New / Properties
5. Condition Properties -> Stimuli -> Imperative Stimulus -> Create New / Properties
