response unit for E-prime 2.0 Professional with ERP hardware

Wed Jun 20 09:36:03 UTC 2012

Hi,

Moved from Nottingham to Helsinki, but yes, the issue remains :) On a
related topic, I made some custom software to use the XBOX360 controller
connected to E-Prime (also, for use as very cheap haptic system) - builds
available here, but I've no problem with releasing the source (in c#). See:
http://cognitology.eu/Experiments.htm (under vibro-tactile feature
integration). For adventurous coders, I suppose. 

Best,

Michiel

I'd also like to thank Ben very much for this information.  I came to this
group looking for instructions on how to build a serial or parallel response
box.  My department won't be able to approve a response box until the fall
and I want some data now... 

The game controller option makes sense for so many reasons, including the
psychological effect or context effect - perhaps pulling for more valid data
- particularly in a stop signal paradigm.   Seems to fit with what Mich
(Psychology, Nottingham; sorry don't have thread handy) elsewhere about
psychological effects as being under-rated in comparison with timing
precision... 

Just to review: I can use a Logitech game pad - for example
http://www.logitech.com/en-ca/gaming/controllers/7360

and download a driver...  I don't actually see a place to download drivers
of the type Ben describes, but there is this information:  

____________________________________

DirectInput (D)

DirectInput mode works with Windows drivers to enable basic input
functionality. This input mode also lets you use the Logitech Gaming
Software to customize the inputs for games that don't normally allow you to
do so, or don't have gamepad support at all.

You can use the Logitech Gaming Software with DirectInput mode to assign a
specific key or key combination to any of the buttons or thumbsticks on the
gamepad. You can also assign each thumbstick to work like a joystick or
mouse.

NOTE: Logitech doesn't provide configuration software for non-Windows
systems, but many games allow you to configure inputs in-game. DirectInput
mode lets the gamepad communicate with the drivers on many such systems.

__________________________________________

...And so using a driver and/or the above information, I will be able to
assign an ASCII key or number to one or more gamepad buttons, right? 

And e-prime will be able to add this device - as an input device or the
type, "response box"?  

And then what about the timing errors?   I'm not so concerned, but can
anyone estimate the timing errors for data logging?  Is there a way to
minimize the error by changing the input refresh rate somewhere?  

Thanks so much, 

Chris

i've used a couple different USB controllers for this purpose over the
years.  they're so much cheaper than the cedrus boxes or the pst response
boxes. 

both controllers i've used, and i would imagine all controllers of this
type, have an accompanying driver which you download from the manufacturer's
website and which allows you to assign a value to the various controller
buttons.  presses on the controller mimic keyboard button presses, so all
you need to do in eprime is set the object collecting responses to look for
a keyboard response (as opposed to a response from a mouse or a pst response
box).  for instance, set the object to accept '0' or '1', and then assign
one button on the controller to be '0' and the other to be '1', turn off all
the other buttons, and you're good to go.

pretty straight forward.

Thanks for this info. Are you using this gamepad with E-Prime? If so,
do you write script to tell the software how to interact with the
gamepad?
