Hi everyone,
I am trying to conduct a basic two-back task that contains 15 letters, which are ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘H’, ‘I’, ‘K’, ‘L’, ‘M’, ‘O’, ‘P’, ‘R’, ‘S’ and ‘T’.
Every letter would be presented for 500 ms and the participants have 2500 ms to react. Participants have to press the ‘space’ if a letter was presented two trials ago; if not, they don’t have to do anything until the next match.
If a participant correctly responded to the stimulus, there would be a “Correct!” feedback showing on the screen right after responding. If one wrongly responded to the stimulus, there would be a “Wrong!” feedback showing on the screen right after responding.
I have two blocks in my task that one block is for practice, which is called “practice_section” and the other is formal test, which is called “formal_section”
I have followed some ways and tips online to try to conduct the task but there were still some problems.
The fist problem is that trials can not carry on to the next trial automatically unless I press the ‘space’.
The second problem is that the feedback messages in my task is never showed up.
Here is my “practice_section” builder.
Here is my “practice_section” code in code component.
Here is my “practice_section” text component properties.
Here is my “practice_section” keyboard component properties.
Here is my “feedback” builder.
Here is my “feedback” code component.
Here is my “practice_section_trial” properties window.
I am still working on the practice section so I have not built the formal section routine yet.
Any advice will be helpful for me.
Thank you for your time.
