Interstimulus intervals -Audio
 
5 Attachment(s)
Hi,

I am new with Superlab . I work with 12 audio files of about 2000 ms each and I would like to establish interstimulus intervals (no sound) that randomly appear between each of the audio files. How can I do it?

* In addition, whenever I run the experience, Superlab indicates a bug and ends before the end. Can you try to run it to see if my computer has a problem or if I made a mistake while using SuperLab?

Thank you!

Are you getting a message about a bug, or a crash report from SuperLab? If you are getting some type of message, can you please take a screen snapshot and post it?

Hi,

Yes, I received a message. I will take a screen snapshot this afternoon.

Still, do you have an answer for my first question? ( I work with 12 audio files of about 2000 ms each and I would like to establish interstimulus intervals (no sound) that randomly appear between each of the audio files. How can I do it? )

Thank you!

I suggest making a third event and using a Trial Variable for ISI Duration. You can find the Trial Variable feature under the Experiment menu. If you don't always want to present an ISI then use 0 ms as one of your time limits. After creating the ISI you can attach it to a new event by choosing "Inter-Stimulus Interval (ISI)" as the Event Type. Under the Input tab check "Only after a time limit. The time limit is" then select "Variable". Here you will see the ISI you created.

Thank you. How do I enter time limits?

This is the screenshot :

This is a crash report and it gives you the option to send the report to us. Are you able to click "OK" to submit the crash report? If not, please refer to the path that is shown on the screenshot you sent:

"C:\Documents and Settings\JPG_Labo\...... SuperLab_dbgrpt"

Then send us the XML file.

Yes, I am able to do it. thank you.

When you say " I suggest making a third event and using a Trial Variable for ISI Duration. You can find the Trial Variable feature under the Experiment menu. If you don't always want to present an ISI then use 0 ms as one of your time limits.

The time limit is" then select "Variable". Here you will see the ISI you created."

How can I enter time limits ? Do I have to Edit the " ISI Durations" in the trial variables, and then enter the time limits as the levels? Will it be in ms?

Double click on "ISI Durations" within the Trial Variables window. Here you can enter the time limits, in milliseconds, under the Levels tab. You can also change the name of "ISI Durations" if you wish to do so.
