Opensesame/Next button

mazmd

Hi all!

I'm new to opensesame and 1) I want to create a questionnaire with a "next" button for the open-ended questions. I understand that there is an option to include the "next" button for the multiple-choice questions but how do I include it for the open-ended questions as well?

2) How do I ensure that the participants can only click the "next" button when there is an input?

PS. I barely have any knowledge on python language.
I really hope I could get some help here!!!! Thanks in advance!! It's really urgent!

Hi Maz,

Have you considered creating a custom-form? You can find rather detailed instructions how to make them here. Let us know if you need more help with them.

Best,

Hi Eduard!!

Thanks! The site helped to resolve the first problem (which is to include a next button in open-ended questions). Appreciate it so much!! Is there any opensesame script to either allow the participant to click the 'next' button only when there is an input or some kind of warning message to prompt the participants to enter their responses if they haven't after clicking the 'next' button?

Hi Jarik! Thanks for the reply! Yes, I'm using OpenSesame 3. I copy pasted your script but I could still click next/advance to the next page. So for example my open-ended question with the next button looks like this:

set timeout infinite
set spacing 10
set rows "1;4;1"
set only_render no
set margins "100;50;100;50"
set form_var response
set form_title Title
set form_question "bla bla bla?"
set cols 1
set _theme gray
widget 0 0 1 1 label text="[form_title]"
widget 0 1 1 1 label center=no text="[form_question]"
widget 0 1 1 1 text_input focus=no return_accepts=no stub="" var="[form_var]"
widget 0 2 1 1 button text=Next var=response_variable

But I could still click the next button without typing in my response.

Jarik

Yes, you should modify things a little In the attached example note the inline script lines:

    if self.get('response') == '':

So the output variable of the form_base item has to be response

    items['new_form_base'].prepare()
    items['new_form_base'].run()

So the title of the form_base item has to be new_form_base

Hi Jarik! Should this script be in sequence item? or can it be in the form item?

Also, I'll have 20-30+ questions, some MCQ/Rating/open-ended questions.

Hi Maz,

A working example is attached to my previous post. There's a little bit of code in the inline_script item (which is in the sequence item after the form). Ones you understand the working example it shouldn't be too hard for you to apply the same principle on the other 20-30+ questions.

Hi Jarik!!

Thank you for all the help and being so patient :'). I kinda almost get the concept! It did throw me an error though for the inline script item.

File "C:\Program Files (x86)\OpenSesame\lib\site-packages\libopensesame\inline_script.py", line 73, in prepare
self.var.get(u'_run', _eval=False))
File "C:\Program Files (x86)\OpenSesame\lib\site-packages\libopensesame\python_workspace.py", line 147, in _compile
return compile(script, u'', u'exec')
File "", line 2
define inline_script new_inline_script
^
SyntaxError: invalid syntax

mazmd

The experiment did not finish normally for the following reason:

Failed to compile inline script
Details

code: define inline_script new_inline_script
item-stack: experiment[prepare].new_sequence[prepare].new_inline_script[prepare]
exception type: SyntaxError

Jarik

Can you upload the experiment or post the code from the inline script that is causing the error? I can't find the problem in the error message(s) you provide.

mazmd

Hi Jarik!

Ok so I tried using your code. I have a form text input item and in it, there's this:
set timeout infinite
set spacing 10
set rows "1;4;1"
set only_render no
set margins "100;50;100;50"
set form_var response
set form_title Title
set form_question "bla bla bla?"
set cols 1
set _theme gray
widget 0 0 1 1 label text="[form_title]"
widget 0 1 1 1 label center=no text="[form_question]"
widget 0 1 1 1 text_input focus=no return_accepts=no stub="" var="[form_var]"
widget 0 2 1 1 button text=Next var=response_variable

Then I included a sequence item after the form text input item and in the sequence item, I used your code provided above:
set timeout infinite
set spacing 10
set rows "1;4;1"
set only_render no
set margins "100;50;100;50"
set form_var response
set form_title Title
set form_question "bla bla bla?"
set flush_keyboard yes
set description "Runs a number of items in sequence"
set cols 1
set _theme gray
run new_form_text_input always
run new_inline_script always

I also included the inline script item in the sequence item and in the run phase (your code as well!):
define inline_script new_inline_script
set description "Executes Python code"
_run
###############################################################################
# Check if text is entered when clicking next; otherwise rerun rating_scale
###############################################################################
while True:
# If the response has the value 'None' or 'yes':
if self.get('response') == '':
# Rerun the item (after preparing it):
items['new_form_text_input'].prepare()
items['new_form_text_input'].run()

    # Else, the experiment advances normally.
    else:
        break
__end__
set _prepare ""

After I tried to run the program, it throws me an error as described above. My apologies for all the trouble, I'm really new to this program and coding entirely!!!

Jarik

You are putting "form code" like set form_question "bla bla bla?" in a sequence item. This won't work.

Note that for some items you will have to use code like for an inline_script item or a form_base item. But for some items like the sequence or the sketchpad item, you can suffice with the graphical user interface. Maybe you will get some more grip on the OpenSesame program by doing/viewing some tutorials:

• http://osdoc.cogsci.nl/3.1/tutorials/beginner/
• http://osdoc.cogsci.nl/3.1/tutorials/video/

Then I included a sequence item after the form text input item and in the sequence item, I used your code provided above:

Note that you normally put things (items like an inline_script item) in and not after a sequence item. You can peek in the osexp file I uploaded here (right click on file and choose Save as...) or in any of the example templates that come with OpenSesame.

Best,
Jarik

Thanks Jarik!! It worked perfectly!
I tried with other type of questions but where did I go wrong this time? I can still click next when I have no user input.
This was my code in the form base item:

set timeout infinite
set spacing 10
set rows "1;1;1;1;1"
set only_render no
set margins "50;50;50;50"
set form_var response2
set cols "1;1"
set _theme gray
widget 0 0 2 1 label text="Indicate how much you agree with the following statements"
widget 0 1 1 1 label center=no text="I think that ex-probationers should work with the community in the future"
widget 1 1 1 1 rating_scale nodes="Agree;Don't know;Disagree" var="[form_var]"
widget 0 4 2 1 button text=Next

and in the inline script:

#

Check if text is entered when clicking next; otherwise rerun rating_scale

#

while True:
# If the response has the value 'None':
if self.get('response2') == '':
# Rerun the item (after preparing it):
items['new_form_base'].prepare()
items['new_form_base'].run()

# Else, the experiment advances normally.
else:
    break

I also included a logger item at the end and when I opened the excel sheet it says "None" under the column of "response2" if I don't select an option and continued with the next button.

Technically you can always click the next button, but the inline script that follows will rerun the form until an answer is given.

I also included a logger item at the end and when I opened the excel sheet it says "None" under the column of "response2" if I don't select an option and continued with the next button.

This is correct behavior right? "response2" is "None" when you don't select an option and continued with the next button.

---

The only thing I can think of that might be the problem is that you use:

items['new_form_base'].prepare()

items['new_form_base'].run()
Is the form called new_form_base?

Hi Jarik,

Yup, the form is called new_form_base (for now). The thing is, I do need to collect the responses, in that case, agree would be scored as 0, don't know as 1 and disagree as 2. I don't want my participants to be clicking "next" without inputting anything because then I would have missing information. Is there any way I can allow the form to rerun again until they select an option like how it worked for the open-ended question?

Also, my open-ended question is new_form_text_input because I need to collect their exact responses that they typed out. The open-ended question ran again (when there is no input) and worked perfectly with your code!

Jarik

OK I see now the test you want to use is:
if var.response2 == None:

---

Note you test for == None instead of == ''for the rating_scale widget in the new_form_base. The output from the logger item kind of indicated this in your previous post

Also note I changed self.get('response2') to var.response2. This is better/easier and new in OpenSesame 3 see:

Best,

That worked perfect!! Thank you so much. I also tried on simple multiple choice questions where the options are "Yes", "No", "Maybe". When there is no input, the output was registered as a "no" in the response column. When there is an input, the output appears as one of the 3 options avail. I tried to do something similar in the inline script where I test for:
if var.response3 == no: (or if var.response3 == None:) but that doesn't work hmm. Ultimately, I have the same goal. I need the form to rerun until an option is selected.

Jarik

Can you try if var.response3 == 'no': or maybe if var.response3 == 'No':

mazmd

var.response3 == 'no' works! Thank you so much Jarik!!! I appreciate it a lot!

Hello everybody,

I'm new in opensesame and I'm a noob ;D.

How do I ensure that the participants can only click the "next" button when there is an input?

This was my code:

set timeout infinite

set spacing 10

set rows "1;1;1;1;1;1;1;1;1"

set only_render no

set margins "50;50;50;50"

set description "A generic form plug-in"

set cols "1;1"

set _theme gray

widget 0 0 2 1 label text="<b><span style='font-size:28px;'>Wie attraktiv sind folgende Merkmale in einer Beziehung?</span></b>"

widget 0 0 2 2 label text="<span style='font-size:18px;'>1:unattraktiv, 2:eher unattraktiv, 3:ausgeglichen, 4:attraktiv, 5:sehr attraktiv</span>"

widget 0 2 1 1 label center=no text=zärtlich

widget 1 2 1 1 rating_scale nodes="-2;-1;0;1;2" var=question1

widget 0 3 1 1 label center=no text=Ehrgeiz

widget 1 3 1 1 rating_scale nodes="1;2;3;4;5" var=question2

widget 0 4 1 1 label center=no text=strenge

widget 1 4 1 1 rating_scale nodes="1;2;3;4;5" var=question3

widget 0 5 1 1 label center=no text=überlegen

widget 1 5 1 1 rating_scale nodes="1;2;3;4;5" var=question4

widget 0 6 1 1 label center=no text=risikofreudig

widget 1 6 1 1 rating_scale nodes="1;2;3;4;5" var=question5

widget 0 7 1 1 label center=no text=kreativ

widget 1 7 1 1 rating_scale nodes="1;2;3;4;5" var=question6

widget 0 8 2 1 button text=Next

thank you!

Hi @pacobenko ,

Did you already have a look at this post?

• https://forum.cogsci.nl/discussion/1437/solved-custom-forms-how-to-activate-a-next-button-only-when-a-checkbox-is-chosen

Perhaps that helps. If not, feel free to get back to us.

Cheers,

PS: the most simple way to advance to the next trial only when all questions are answered, is to place an inline_script item after your form_base item and place the following code in its Run phase tab:

# Make a list of all the response values:
responseList = [var.question1, var.question2, var.question3]

if None in responseList:

	# Rerun the item:
	items.execute(u'form_base')

Perhaps that helps.

Cheers,

Lotje
