In the section menu, you can create conditions that are evaluated after each trial.
A trial is the presentation of all the scenes of a section consecutively.
The order of the conditions in the menu is the order in which they are evaluated.
If a condition is true, the action associated with that condition will be performed and the following conditions will not be evaluated.
Possible conditions:
- when the number of trials = n
- when the number of trials responded in time = n
- when the number of trials not responded in time = n
- when the number of correct trials = n
- when the number of incorrect trials = n
- when the last trial was responded in time
- when the last trial was not responded in time
- when the last trial was correct
- when the last trial was incorrect
- when all the section trials have been performed
Possible actions:
- move to another section
- end the test
If neither condition is true, a new trial in the same section is performed.
Practical case
Suppose you have a test consisting of 100 trials.
You want to present a message when the participant has performed half of the trials.
You want to present another message to encourage the participant when the number of incorrect responses reaches a certain value.
In this particular example you need 3 sections:
- sectionMiddle: containing a scene with a text message: “You are halfway through the test!”. It consists of a single trial.
- sectionWrong: containing a scene with a a text message: “Please concentrate. You can do better!”. It consists of a single trial.
- sectionMain: contains your main scenes and consists of 100 trials.
In sectionMain you need the following conditions:
- when the number of trials = 50: sectionMiddle
- when the number of incorrect trials = 30: sectionWrong
- when the number of incorrect trials = 50: sectionWrong
- when all the section trials have been performed: End the test
In sectionMiddle and sectionWrong you need a single condition:
- when all the section trials have been performed: sectionMain
