Memory tasks (case 17441)
I wish to design an experiment that incorparates a Digit span task.
Digit span - 2 to 7 long strings of digits will be presented, one digit at a time. After a string has been presented the participant must press the corresponding numbers using the keyboard.
Upon answering correctly the experiment should move to a "harder" trial with an additional digit. An example would be, "1 3" are presented, the participant answers "1 3" and the next trial is "2 5 3". Upon making a mistake the block ends.
If you have / know who has such a direct rt file, I would be delighted to use their design. If not any advice would be great as it's been a while since I last used Direct RT.

David,
Did you want the string of numbers to stay on screen or disappear when the participants pressed keys?

Similarly to an online cognitive test, a string shuold consist of X amount of digits apearing sequencially in intervals of 1 second. Once the last digit of a string fades (after also being presented for 1 second only) the participants may enter their answer.
The digits should appear as participants clicked them for self monitoring. After two trials of the same string length the next couple strings will include an additional digit (starting with 2 strings of 2 digits and eventually reaching 2 strings of 7 digits).
Thank you for you help
Could you please elaborate more on what you mean by "as participants clicked them for self monitoring?" I thought you were looking for participants to type the answers as open-ended responses from your first post, but your more recent post makes it sounds like you wanted to use the mouse for participant responses. Please forgive all the questions, but I just want to make sure that I understand the key aspects of your task so as to give you the best information about what DirectRT can do.
