Multiple Response Collection [30022]

This article applies to:
E-Prime 3.0
E-Prime 2.0
E-Prime 1.x

 
Detail
This sample demonstrates the methods used to collect multiple responses via a single Input object, and how to collect individual reaction times (as well as other statistics) for each individual response.
 
Abstract
These sample experiments illustrate how to collect multiple Mouse, Keyboard, SRBox, Joystick, or Chronos responses using a single input object. 

A 'TextDisplay' object is used on each Procedure to display the stimulus. The device used to present the stimulus has its 'Max Count' property set to 2.

After the participant responds, an InLine script object uses a 'ResponseData' variable to access information (i.e., RT, cursor position, etc.) about each individual key or button press. This information is stored in an attribute using the c.SetAttrib command and referenced later in the corresponding 'Statistics' object.

Joystick, SRBox, and Chronos versions of this sample are included as well. The joystick used must be recognized by Windows as a joystick/gamepad or Human Interface Device (HID). Additionally, verify that the SRBox device is configured to use the proper COM port (if using the SRBox sample).

NOTE: The joystick experiment is for E-Prime 3.0 and E-Prime 2.0 Professional only.

NOTE: The Chronos experiment is for E-Prime 3.0 and E-Prime 2.0 only.
