RE: Using keyboard instead of a mouse

Please review my 1st reply where you will find all of this already covered. You need to do this

<trial yourturnexcludedbyA>
/ stimulusframes = [1=ball3, blank2, blank1]
/ validresponse = (*enter scancode for player 1 key*, *enter scancode for player 2 key*)
/ inputdevice = keyboard
/ branch = [if (trial.yourturnexcludedbyA.response == *enter scancode for player 1 key*) trial.player1turnexcludedbyA3to1]
/ branch = [if (trial.yourturnexcludedbyA.response == *enter scancode for player 1 key*) trial.player2turnexcludedbyA3to2]
</trial>

throughout. For help with scancodes please review the respective documentation topic and see Tools -> Keyboard Scan Codes...

Hi Dave,

Here's the relevant code for one of the conditions. I don't think I'll be able to solve this without your help. Thanks in advance!

I cannot tell you without you providing the relevant code. If I were to hazard a guess, you have probably misspecified the /branch attributes. You *must* use keyboard scancodes as already detailed in my previous reply.

Hi Dave,

Thanks for your reply. I followed everything you said and now what happens is that when I press on the keys (either e or i - doesn't matter), it automatically goes to the next page without letting me play the game. What do you think the problem might be?

Thanks!

You need to set inputdevide to keyboard, enter the keys scancodes in validresponse and adjust the branches accordingly. More importantly, though, you'll to work through the original (mouse input) script until you sufficiently understand how it works before making any of these modifications. Otherwise you are going to break the code.

Using keyboard instead of a mouse

gsu — Mon, 30 Sep 2013 17:47:24 GMT

Hi,

We are using Inquisit for Cyberball in our lab and until now, participants selected which player they wanted to throw the ball to using the mouse. Now, we want them to use the keyboard. How can I assign keys to each player? Also, how can I make sure that those keys are the valid responses in each trial?

Here's an example of a trial where we defined the input device as the mouse:

/ stimulusframes = [1=cyberball, turninstructions12, start]

/ validresponse = (start)

/ inputdevice = mouse

/ responsemessage = (start, blankscreen, 0)

/ recorddata = false

</trial>

Here's another example:

/ stimulusframes = [1=ball3, blank2, blank1]

/ validresponse = (player1, player2)

/ inputdevice = mouse

/ branch = [if (trial.yourturnexcludedbyA.response == "player1") trial.player1turnexcludedbyA3to1]

/ branch = [if (trial.yourturnexcludedbyA.response == "player2") trial.player2turnexcludedbyA3to2]

</trial>

Thank you in advance,

Gizem
