[open] Limit the time to start input text

Shilog

My question is very simple (I hope the answer also...) -

I want subjects to recall a sequence (shown with a sketchpad) -
I do this with a form_text_input item -
but I do not want them to "take the time" I want to remind them they need to answer.
Is there a way to wait for their answer (I want to check RT), and yet after some seconds remind them
to answer.

(It seems like I do my research on sleeping people. No, It's just what was asked me to do)

Thank you a lot,
Shilo

actually,
I convinced the research-student that she doesn't need the reminder,
but I have another problem -

When I (the program) wait for response to the sequence,
I couldn't actually record it - the first letter is missed,
and the subject need to rewrite it in second he sees it wasn't writen.

yes I know - it is saved on the logger, but
I want the subject won't be confused with what he typed or not.
If it was keyboard response I'd let the duration be "0",
but I couldn't do this in the case of input_text_form...

thank's a lot for reading all these pettiness,

Hi Shilo,

Do I understand correctly that you use a regular form_text_input, but that this does not register the first typed character? If so, could you post the script of your experiment, or a clearer description of what you're doing precisely?

Cheers!

actually,
I found a script of Sebastian that was mantioned here that suited me.

http://forum.cogsci.nl/index.php?p=/discussion/31/solved-multi-character-keyboard-response-or-simultaneous-sketchpad-and-text_input/p1

Now I have another problem. (the oposite one)

my sequence its:

fixation

word (sketchpad with a duration set to 7000)

word waiting (sketchpad with a duration set to 0)

the_script

logger

I want him to start record the letters only while the second
scatchpad is shown. but the programm record the letter that was typed
while the first one was shown.

                    Thanks a lot,
                            Shilo

Not sure which script you used, but I assume it's the simpler one (not PyGame specific). I've added two lines in there to call the get_key until all previous input is gone. Now the script should only collect the stuff typed while the second sketchpad is visible.

# import the stuff we need
from openexp.canvas import canvas
from openexp.keyboard import keyboard

# create the instances we need
my_canvas = canvas(self.experiment)
my_keyboard = keyboard(self.experiment)

# catch all early responses
while my_keyboard.get_key(timeout=1)[0] != None:
    pass

# empty string to store the response
resp = ""

# loop until 'break' is called
while True:
    # Get a keyboard response
    key, time = my_keyboard.get_key()
    # If return is pressed the loop should be exited
    if key == "return":
        break           
    # Handle backspace by removing the last character
    if key == "backspace":
        resp = resp[:-1]    
    else:
        # add character to response
        resp += key
    # Copy the canvas from a sketchpad called 'my_sketchpad' and
    # overlay the response
    my_canvas.copy(self.experiment.items["my_sketchpad"].canvas)
    my_canvas.text(resp)
    my_canvas.show()    
# Save the response
self.experiment.set("response", resp)

Good luck!
