collecting subject responses

[Tony Zuccolotto]

Dr. Mitchell,
 
There is no strict need to use a Feedback object unless you want to give
the subject some type of feedback upon response (or upon the expiration
of the response time limit in the case that no response was made).
 
As long as you have enabled a keyboard input on one of the objects in
your trial sequence and you have Data Logging enabled for that object
then you should get all your default dependent measures logged in the
data file.
 
Nearly all of the E-Prime sample paradigms include Feedback primarily to
clearly demonstrate that responses have been collected while the
experiment is running so I expect some users may have assumed that a
Feedback object must always be required.  That is not the case - just
use it when you need it.
 
Best Regards,
Tony

	Subject: collecting subject responses
	
	

	Hi
	Someone told me that in order to collect data on a subject's
response to a
	target stimulus that you have to have a feedback object straight
after the
	target
	When I told her that I didn't want the subject to actually get
any feedback,
	she said I still needed one, but that I set it to show nothing
to the
	subject
	But, can't I collect data on how the subject responds from a
target stimulus
	on its own, if I have enabled keyboard input?
	
	This is only my 2nd week of eprime, so sorry for this being so
basic
	
	Thanks in advance
	Rachel
