AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Sobana,

What do you mean by "Time"? The order of the two tasks, or pre vs post-task? The answer is NO because Day is essentially the same thing as Task. On the other hand, "set" or Group is another (between-subjects) factor of interest, right?

Do reaction times and accuracy vary between tasks and the time points?
