SlideChoice Scoring [35388]

This article applies to:

E-Prime 3.0

Detail

The SlideChoice sub-object can be configured in different ways such that by using certain combinations of properties can present and score information for a variety of types of questions.

Abstract

Because this sample varies the way that questions are configured per trial, Attributes are created in a List to hold the values of the stimuli presented as well as SlideChoice sub-object properties that vary per trial. Attribute references are used in the SlideChoice sub-object properties.

By default, when adding a SlideChoice to a Slide, logging specific to the SlideChoice is enabled. The .ACC, .RT, and .RESP of the SlideChoice can be propagated to the parent Slide so that the Slide's .ACC, .RT, and .RESP reports that of the SlideChoice. This can be done by setting the Slide's Input Sources to the SlideChoice in the Slide Properties under the General tab.

By opening the SlideChoice sub-object properties, its table of items is listed. The RESP Source property indicates which value from the "Items" table beneath it will be logged as the SlideChoice response in the data file, and is also used to calculate the accuracy of the response. Accuracy Mode and IncludeACC work together. When judging the accuracy of a choice that is made, IncludeACC can be thought of in terms of "Is this choice correct?" and specifying Yes or No. In some cases, there may be multiple correct responses, in which case IncludeACC would have multiple rows specified as Yes. Accuracy Mode determines if choosing any of the items yield a correct response or if all of the items that have IncludeACC set to Yes must be selected to yield a correct response.

The Value and DataTag column in the table can be used for additional user information. For example, in this sample the DataTag is used to refer to the options as A-D. The Ordinal represents the position of the items and will always remain static. Value and DataTag are also set static but can be varied by using Attributes.

The RESPProc presents the same question 4 times however, the RESPSource will change per trial. Feedback will be given after each trial to show how the .RESP and .ACC is reported. Because the Slide's Input Source is set to Choice1, the .RESP and .ACC of the Slide is referenced to show that it is reporting based on that of the SlideChoice.

The ScoreProc presents different questions. A List object holds the combinations of properties needed to configure each type of question. A description of how the question is setup and how it will be scored appears above the main question. The RESPSource remains static. Feedback will be given showing the .RESP and .ACC of the Slide which will be that of the SlideChoice due to the Slide's Input Source.
