subtest3: Nonemotional Prosody Discrimination
Participants are presented two sentences, one after the other, spoken by the same actor and have to decide whether the statements are the same or different. The sentences are either both declarative statements (same), or both questions (same), or one of each (different). Participants work through 6 trials.
1 Testblock of 6 trials
- 3 trials with identical sentences
- 3 trials different sentences
The order of the statements is predetermined.
Participants can select button 'same' or 'different'. Responses can be changed until 'next' is pressed.
If button 'repeat' is pressed, the statements get repeated.
By setting parameters.showadvanceButton to true, a '?'-button appears in the upper right corner.
If pressed, the next scheduled test item is skipped.
