keyboard is designated as the Input Mask device, the allowed response keys (Allowable field) are
1 and 2, and the Correct field is set to refer to the CorrectResponse attribute (defined in the
DesignList). The End Action is set to the “Terminate” option to terminate the display when the
subject responds. These properties are set on the Duration/Input tab of the Probe TextDisplay
object (see arrows below).
2.2.6 Step 1.6: Specify what data will be logged for
analysis
For a research experiment, the experimenter has to record and analyze data. This requires
clarity on what variables will be logged. Be able to answer, “What dependent measures will be
recorded in reference to specific objects in the experiment?” The abstract above stated: The
dependent measures are the response, response time, and response accuracy of the Probe
display. After a trial, expect to record the following information for the Probe display: What was
the response that the subject entered (i.e., 1 for word and 2 for nonword)? What was the
response time? What was the accuracy (i.e., 1 for correct and 0 for wrong)?
In E-Prime, each object is capable of logging multiple properties. Setting the data logging for an
object to “Standard” will result in the logging of the RESP (response), RT (reaction time) and
ACC (accuracy) properties (as well as other dependent and time audit measures). Data logging
is set via the Duration/Input tab in the object’s Property pages.
