[visionlist] IRB question

[Mark McCourt]

Dear Fellow Psychophysicists:

 

I've encountered an interesting problem. We applied for and received IRB
approval for a psychophysical experiment which we estimated would require 90
min for subjects to complete. Since obtaining the approval we have made some
minor modifications to the experiment (i.e., reducing the number of levels
of the independent variables and reducing the number of trials per
condition) which has reduced the anticipated time to complete the experiment
to about 60 min. I am informed by my IRB that I will need to file an amended
protocol as a consequence of this (what seems to me totally innocuous and
irrelevant) change. So, my question is: Is this a reasonable requirement or
is it Kafkaesque? Thanks!

 

-Mark
