Psychtoolbox - exit out of loop with keypress

Hi everyone,

I was wondering if someone could help - I am having a bad computer day. I want to make a really simple program where a

• random number is presented on screen
• the program randomly selects whether to +1 or -1 to that number
• if it chooses to add one, play a high tone - and +1 to the starting number
• if it chooses to subtract '' low tone '' -1
• And to keep doing this until a key press happens (enter or escape or something)

I have put something together that basically works, aside from the exiting out on keypress - the program does not seem to get/ respond to key presses inside the program i.e., my KbCheck at line 98 does not seem to work. As I press it just types into the main screen.

keyIsDown = 0; % initialise to 0

while 1 % keep running until Q is pressed

[keyIsDown, secs, keyCode] = KbCheck;

FlushEvents('keyDown');

if (keyIsDown)

if keyCode(escKey)

ShowCursor;

Screen('CloseAll');

return

else

end

end

The thing I used to wait until mouse is clicked between trials works but looks a bit messy

clear buttons

[~,~,buttons]=GetMouse;

while ~any(buttons)

[~,~,buttons]=GetMouse;

end

clear buttons

[~,~,buttons]=GetMouse;

Any help would be greatly appreciated!
