Restricting response window (case 21255)

[mkclairhong]

Hi,

I have a trial in which the participants are required to fill in the blanks of the word stem (e.g. ap_ _ _). I want to set the trials to 8 seconds but since I want to make sure that people have enough time to answer it, I want the word stem to go away after 8 seconds (in order to control for stimuli exposure time), but still want the answer box alive until they hit "enter" to proceed to the next trial. I also do not want them to be able to move onto the next trial before 8 seconds have passed, in order to make sure that people won't race through the trials. I've learned how to project the stimuli for 8 seconds through the information on the forum, but my I am struggling to find answers for the problems below:

1. I want the response box to pop up with the stimuli
2. I want the stimuli (word stem) gone after 8 seconds but the answer box to be still there after 8 seconds
3. I want to prevent people from hitting the enter key before 8 seconds have passed (they can press enter whenever they after 8 seconds).

Please let me know if you have any idea about how to tackle those problems. Thank you for your help in advance!

Do you want to use MediaLab or DirectRT to do this task?
