Overview
The SlideSlider sub-object may be added to a Slide to allow presentation of a variety of survey-type stimuli (e.g., Likert scale, multiple choice/multiple selection/bipolar questionnaires). The SlideSlider sub-object will vertically and horizontally center its drawing components within the frame defining the size of the sub-object (see Frame below). Individual components of the SlideSlider (e.g., axis, tick marks, labels) may be configured using the property pages.
When an input mask is enabled on the parent object (i.e., Slide or FeedbackDisplay), the SlideSlider sub-object may be used as a response input option (i.e., like the keyboard or the mouse). See the General tab section in E-STUDIO: Slide Object [22701] for information pertaining to specifying a SlideSlider sub-object as an Input Source, and the Response Inputand Logging sections below for additional information).
The property pages for the SlideImage sub-object permit the configuration of the size and appearance of the sub-object on the parent object.
General
The General tab within the SlideSlider sub-object property pages allows configuration of the slider, including the range and orientation of the slider.

Frame
The Frame tab is used by the SlideSlider sub-object to define a rectangular area on the parent display area (e.g., SlideState) as the display area for the sub-object.
The rectangular area defined by the properties is referred to as a “Frame.” Refer to E-STUDIO: Frame [22716] for more information concerning Frames. Note that there are separate Frame properties for a SlideSlider sub-object, the SlideState on which it resides, and the parent Slide object that houses both of them. Be careful to select the appropriate element for which you wish to configure the Frame.

Appearance
The SlideSlider sub-object will vertically and horizontally center its drawing components within the frame defining the size of the sub-object. The Appearance tab permits the formatting of the elements composing the SlideSlider sub-object. Like the SlideButton sub-object from which it is derived, the properties of the SlideSlider sub-object are based on a theme, or a collection of settings. This collection of settings is accessible via the Appearance tab within the SlideSlider property pages.
Theme
The properties of the SlideSlider sub-object are based on a theme, or a collection of settings. This collection of settings is organized on the SlideSlider's Appearance tab.
Parent Theme
Properties are, by default, inherited from a parent theme, which may be edited using the Theme Editor (see E-STUDIO: Theme Editor [23585]). When editing the parent theme, modifications will apply to all SlideSlider sub-objects within the experiment (e.g., modifying the BaseSlider Parent Theme to apply a border will result in a border being applied to all SlideSlider sub-objects within the experiment).
|
Field |
Possible Values |
Description |
|
Parent Theme |
BaseChoice, BaseButton, BaseSlider, any user-defined custom themes |

Response Input
At runtime, the user may navigate through the SlideSlider items using a pointer device (i.e., mouse or joystick), or the keyboard. To enable input via a specific device, configure the Input Device to Filter field for the Button Device in the Experiment Object property pages (see E-STUDIO: Button Device [24411].
When using a pointer device (e.g., mouse), the primary button may be used to click on the axis of the slider within the allowable range (i.e., Value Min to Value Max). This allowable range is extended a small amount (i.e., roughly 10 pixels) beyond the minimum and maximum value to allow flexibility of response location in regard to the ends of the defined range. When clicking the axis, the indicator and value are adjusted to reflect the location of the response. In addition, the primary mouse button may be used to perform a click+drag operation. During the drag operation, the value and indicator are updated to reflect the current location of the pointer.
When using the keyboard, the left or down arrow keys may be used to move one unit as configured by the Value Snap To field (i.e., Major, Minor, or Custom) toward the range minimum (i.e., Value Min). The right or up arrow keys may be used to move one unit (again, as configured by the Value Snap To field) toward the range maximum value (i.e., Value Max). The page down and page up keys may be used similarly to move one unit (i.e., toward the minimum or maximum value within the range, respectively) as defined by the Major Tick Units field. Each movement updates the value and indicator to reflect the current location.
Logging
The SlideSlider is derived from the SlideButton, and extends the measures automatically logged in the data file. The table below indicates the additional attributes appearing in the data file when input is collected via a SlideSlider sub-object. Each of the attributes appears as a property associated with the sub-object (i.e., <SlideSliderName>.<PropertyName>).
|

|
RTTime |
Timestamp of response to SlideSlider sub-object relative to the beginning of experiment execution. |
|
ACC |
Accuracy of response (0 or 1). Refer to Accuracy Range Min/Max. |
|
ResponseCount |
Number of responses. Because of the Default Value, ResponseCount always = 1, even if no participant response occurs. |
|
ChangeCount |
Number of response changes |
