IAT

nadinev — Mon, 30 Nov 2020 14:00:39 GMT

Hello,
I'm new to Inquisit and would like to use a modified version of the Internal vs. external attention task (IAT) from Mansell, Clark & Ehlers (2003) which can be downloaded from the Millisecond Test Library. Has anybody used the test before and can tell how to connect the vibration sensor to the PC so that it can be controlled by Inquisit? Do I need a Arduino for this or is there another way? (We use Inquisit 4, an update to Inquisit 6 would be possible.)
Thanks in advance!

Hello Dave,
thank you for your reply. Unfortunately, we'll use a laptop (neither a parallel port nor an express card slot...). Is there another possibility how we can adapt? Can the vibration motor be attached to the USB port?

Theoretically yes if the device presents itself as a serial device. Then you can configure your <port> elements to use the serial (COM) port instead to send signals to the device. Note that serial port communications are only supported under Windows., it won't work on Macs.

The scripts assume the vibration sensor is attached to the computer's parallel port. See the <port> elements in the script. You may have to adapt those for the specific hardware you have available.

See https://www.millisecond.com/support/docs/v6/html/howto/howtosendport.htm and https://www.millisecond.com/support/docs/v6/html/language/elements/port.htm

You can use the parallel port monitor tool to aid you in figuring out the correct settings for your hardware. https://www.millisecond.com/support/docs/v6/html/howto/howtoportmonitor.htm
