object (in the Structure view) to open it in the Workspace, and click the Property pages tool button
(top left corner of the Probe window) to open the Property pages. Select the Duration/Input tab
by clicking on it. Then, set the fields as illustrated below. Enter “2000” in the Duration field. To
specify the input devices, first click the Add button in the Input Masks list (lower left) to add an
input device (e.g., Keyboard or Mouse). Then, set the Response Options fields to define the input
conditions.
The fields in the experiment that vary may be set using attribute references. In the DesignList
object we defined the attribute “CorrectResponse” to code what the correct response is. The use
of [] indicates that the field Correct is usually a List attribute (such as [CorrectAnswer]). The End
Action can be set to Terminate if it is desirable for the subject's response to terminate the display.
Note that there are more Property pages. Click on each of the Property pages and examine the
fields. These fields are described in the Reference Guide and in the E-Basic Online Help.
2.3.6 Perform Step 1.6: Specify what data will be
logged for analysis
2.3.6.1 Set Data Logging to Standard for objects collecting
data for analysis
For each object, set the variables that are to be logged. The default in E-Prime is to log all of the
attributes defined on a List object. The experimenter must go to each object and specify what is
to be logged. For most experiments, this will involve setting the data logging option on the
Duration/Input tab to the Standard option. This logs the response variables of RESP, RT, and
ACC for the response key, and the response latency. For assistance, E-Prime will ask to set the
Data logging option to Standard whenever a value is specified for the Correct field (the rationale
being that specifying the correct answer will most likely facilitate analysis of the result later). In
addition, Standard data logging records Time Audit data to verify the timing of the experiment.
