E-STUDIO: Configure KeyboardDevice for Auto Response [22739]

Configure the KeyboardDevice to utilize Auto Response

To configure the keyboard to use AutoResponse, the following steps must be followed:

1. Open the Experiment Properties dialog box by double-clicking on the Experiment object in the
   Structure window.
2. Select the Devices tab.
3. Select the Keyboard Device.
4. If necessary, enable the keyboard device by clicking on the check box next to the Keyboard
   name.
5. Select the ‘Edit…’ button to display the Edit Keyboard properties pages.
6. Select the Auto Response tab to display the Auto Response dialog and modify the default settings as required.

Availability
When Auto Response is enabled in the Experiment Object, Auto Response is, by default, available for input masks (e.g. E-Prime will automatically generate a keyboard response for all display objects which specify an InputMask). Auto Response may be enabled by running the experiment in Test Mode (described below), or by enabling this feature in E-Basic script. To do the latter, enter the following in an InLine object:
 

Rte.AutoResponseEnabled = True

Response Window
By default, AutoResponse will generate a response within 25% to 75% of the response time limit, assuming that a limit is specified. One or both of these values can be modified. If the time limit on the display object is infinite, or if the display object is at the end of the procedure, the time limit is treated as being 1000 ms. This value may be changed as well.

Probability
By default, Auto Response will attempt to maintain a correct response rate of 80%. This value may be changed.

Choices
By default, there are no Allowable values specified in the Choices box to handle cases when the allowed response is set to {ANY}. To restrict the values from which Auto Response will generate a response, specify one or more values in this field.

Multiple Responses

Options for multiple responses during E-Run Test can be edited. By default, when an Input Mask has a MaxCount greater than 1, a number of responses will be between 25% and 75% of the MaxCount. Furthermore, a delay minimum of 30ms will occur between multiple responses.
