Logging
The Logging tab allows the user to select specific attributes to log for each object. On the Logging tab, the automatic measures available within E-Prime are listed and categorized (i.e., Dependent Measures, General, Time Audit, etc.). Click the checkbox next to each attribute to set the logging status.
The following table defines the measures that may be automatically logged for an object collecting input. An entire category of measures may be selected through the Data Logging field on the Duration/Input tab.
NOTE: The following table lists SlideChoice and SlideSlider properties as beginning with Choice1 and Slider1 respectively. This is the default value for a newly created Choice or Slider objects, and the name of the property will change depending on the name of the Choice or Slider object (e.g. ChoiceABC.ACC, ExperimentSlider.RTTime, etc.).
| Property | Category | Description |
| ACC | DependentMeasures | Reflects the accuracy of the response logged by the input object. ACC is based on a comparison of the RESP and CRES Pproperties. |
| CRESP | DependentMeasures | Returns the correct response associated with the input collected by the object. This property is generally set internally according to the value in the Correct field in the Response Options for an object, but may be set via script at run-time. |
| RESP | DependentMeasures | Returns the last (i.e., for single response input) or entire response (i.e., for multiple response input) collected by the object. |
| RT | DependentMeasures | Returns the reaction time of the last input collected by the input object, timed relative to the start of the input. |
| RTTime | DependentMeasures | Returns the reaction time of the input relative to the start time for the experiment. |
| Tag | General | Defines a string value to be logged with the object. This is a generic property to allow the user to associate some data with the object. |
| Choice1.ACC | SlideChoice | Subject's response accuracy to SlideChoice Sub-Object (0 or 1). |
| Choice1.ChangeCount | SlideChoice | Count of response changes. |
| Choice1.RT | SlideChoice | Subject response time (ms) to SlideChoice Sub-Object. |
| Choice1.RTTime | SlideChoice | Subject response timestamp to SlideChoice Sub-Object in relation to beginning program execution. |
| Choice1.ResponseCount | SlideChoice | Count of responses. |
| Choice1.Value | SlideChoice | Value of SlideChoice selected. |
| Choice1.ValueDataTag | SlideChoice | Data tag of value. |
| Choice1.ValueLabel | SlideChoice | Label of value. |
| Choice1.ValueOrdinal | SlideChoice | 1-based integer value of item position. |
| Slider1.ACC | SlideSlider | Subject's response accuracy to SlideSlider Sub-Object (0 or 1). |
| Slider1.ChangeCount | SlideSlider | Count of response changes. |
| Slider1.RT | SlideSlider | Subject response time (ms) to SlideSlider Sub-Object. |
| Slider1.RTTime | SlideSlider | Subject response timestamp to SlideSlider Sub-Object in relation to beginning program execution. |
| Slider1.ResponseCount | SlideSlider | Count of responses. |
| Slider1.Value | SlideSlider | Value of SlideSlider selected. |
| DurationError | TimeAudit | Difference between the Duration property setting and the actual duration. |
| OnsetDelay | TimeAudit | Difference between the TargetOnsetTime and the actual OnsetTime. |
| OnsetTime | TimeAudit | Timestamp at which the object begins its critical action (e.g., drawing to the screen). |
| OnsetToOnsetTime | TimeAudit | Difference between the next and this onset time. |
| ActionDelay | Time Audit (Extended) | Amount of time necessary for the object to perform its critical action (e.g., drawing to the screen). |
| ActionTime | Time Audit (Extended) | Timestamp at which the object finished performing its critical action (e.g., drawing to the screen). |
| CustomOffsetTime | Time Audit (Extended) | Sets the target offset time when custom timing is in use. |
| CustomOnsetTime | Time Audit (Extended) | Sets the target onset time when custom timing is in use. |
| Duration | Time Audit (Extended) | Determines the intended duration of the object in milliseconds. |
| FinishTime | Time Audit (Extended) | Timestamp at which an object has finished the execution of its Run method. |
| OffsetDelay | Time Audit (Extended) | The difference between the TargetOffsetTime and the actual OffsetTime. |
| OffsetTime | Time Audit (Extended) | Timestamp at which the object’s offset action (i.e., clean- up)began executing. |
| PendingInputMasks | Time Audit (Extended) | Logs if any input masks are still collecting input at the end of a procedure. |
| PreRelease | Time Audit (Extended) | Time released during the duration of the current object (after the object finishes its critical action) to allow for setup of the next object. |
| StartTime | Time Audit (Extended) | Timestamp at which execution for the object began (i.e., time at which the Run method began to execute). |
| TargetOffsetTime | Time Audit (Extended) | Calculated timestamp used by an object as the target time for offset (i.e., begin clean up action). |
| TargetOnsetTime | Time Audit (Extended) | Calculated timestamp used by an object as the target time to begin performing its critical action (e.g., drawing to the screen). |
| TimingMode | Time Audit (Extended) | Sets the timing method to be used by the object. Cumulative timing is used to absorb the processing time between events, and to maintain a certain interval duration between events or between trials. |
