Break if statement not working

Mollie_H

Hello,

I want the loop to break if the participant gets more than three correct. I have put this in the break if field and nothing happens. Any ideas? Thanks so much!!

=len(responses.correct) >= 3 and None not in responses.correct[:3] and 0 not in responses.correct[:3]

Hi Mollie,

having complex if statements in the run if of break if field is quite tricky. It is very easy to mess things up and debugging takes a lot of time. I recommend you use an inline_script and following syntax:

# this code has to be in the run phase of an inline_script after the keyboard item.

if len(responses.correct) >= 3:
    if None not in responses.correct[:3]:
        if sum(responses.correct[:3]) == 3:
            print 1
            items['block_loop'].var.break_if = u'always'
            items.execute('block_loop')

Also you need to make sure that before you enter the block loop, you set the break if field back to never. To do so, paste items['block_loop'].var.break_if = u'never' in an inline_script in the sequence before theblock_loop`.

Hope this helps,

Eduard

Hey Eduard!
Thank you so much for your response. I am still having trouble making it work. It runs but it does not break the loop after three correct answers. I'm not super sure what I am not doing properly. I have attached the experiment and I would greatly appreciate any help. Thank you so much again.

best,
Mollie

Hi Mollie,

the problem is that you compute the correct response after the current response has been added to the response history. Add this line responses[0].correct = var.correct to line 5 in your correct_response_2_1_1_1 inline_script and it should work.

Best,
