Variable MultiPage MultiLine Text with Questions

Required Experiment Builder Version: 1.5.58 or higher
EyeLink Required: Yes
Type: Complete Example
Difficulty Level: Easy to Intermediate

This example illustrates:
  • How to use Conditional nodes to check how many pages of text and how many questions to present to the participant
  • How to use Sound nodes to play audio feedback after participant's response
Description:

Each trial in this experiment consists of the presentation of one or more (currently up to five) pages of multi-line text followed by one or more (currently up to three) questions referring to information in the text. The participant reads each page of text, pressing any button on the control pad when finished to advance to the next screen. The questions, which are all true/false, are answered by pressing one of two buttons on the control pad. The order of trials is random, but the order of presentation of the various display screens (pages of text and questions) within a trial is fixed.

Note that the two examples in this thread are the same in terms of the experience of the participant. However, there is some important differences exist in terms of its Experiment Builder structure and capabilities. See below for the differences between these two examples.

**Additional detailed information about the project is given in the notes section for most nodes. To see notes for a given node, either mouse over that node or click on it to display the notes window. If the notes window is not visible, go to the "View" drop down menu in Experiment Builder, select "Properties", and check "Note".

Variable MultiPage MultiLine Text with Questions Alternate Version

Required Experiment Builder Version: 1.5.58 or higher
EyeLink Required: Yes
Type: Complete Example
Difficulty Level: Easy to Intermediate

This example illustrates:
  • How to use Conditional node and Data Source to perform a Drift Check on a subset of trials
  • How to use Update Attribute node to reset TRIAL information to present either just Page Text or Text with Question
Description:

Each trial in this experiment consists of the presentation of one or more pages of multi-line text followed by one or more questions referring to information in the text. The participant reads each page of text, pressing any button on the control pad when finished to advance to the next screen. The questions, which are all true/false, are answered by pressing one of two buttons on the control pad. The order of trials is random, but the order of presentation of the various display screens (pages of text and questions) within a trial is fixed.

This example experiment differs with the above example in the experimental structure in a few ways: First, this alternate version has a structure that may make it easier to modify to accommodate different experimental paradigms. If you want to change the experimental procedure in terms of the maximum number of text screens or questions a given trial can have, you can simply modify the TRIAL Data Source to add more text screens or questions. This modification is possible because in this version, each trial component occupies its own TRIAL Data Source row. For the other version if you want to increase the number of text screens or questions allowed, you must change the TRIAL structure so that more text screen sequences or question sequences are added. Furthermore, you must modify the number of columns in its TRIAL Data Source so that it allows for reference to more text screens or questions.

However, the drawback of this alternate version is that it makes selecting out trials where incorrect responses were made more difficult in Data Viewer. In this version each trial component (text screens and questions) occupies its own row in the TRIAL Data Source, so it is not linked to the other components of the trial. In the other version each component is stored in a different column of the same row in the TRIAL Data Source, which links all the components together. That linkage makes selecting out trials where a participant made an incorrect response to a question easier in Data Viewer. For this alternate version this selection process would be more manual and time consuming.
