Help with experiment radiobuttons (never used inquisit before)

Hi,
I'm very new to this programming language, and even though I've done some tutorials I'm still kind of lost on how to define certain things, like amount of trials.

I need to create an experiment where 2 pairs of stimuli are shown for 26 trials something like this:

10 euro now 23 euro in 2 weeks

the amount of money and weeks should change based on a simple increase of percentages... that i can caluclate, but I'm not sure where on the script i should do this, as adding the amount of trials... also I have no idea on how to input all the stimuli (26*3 options) if I'm using the radiobuttons.. as you can read I'm completely lost.

An experienced user suggested to use radiobuttons... I would like people to be able to click either option as I did on my psychopy experiment... (I'm not using that because I will put this experiment online)

Also I'm not sure on how to record the answers I would need an "output file" that records the amounts shown and the choice made... also another question... in which format does inquisit gives the output files? Im using that file further to generate some stimuli later...

At the end of this I would like to ask some ratings of 5 images form 1 to 10... I think this is also very easy to do, but still i have no clue how...
Even more complicated I created a "lottery" with a 1% chance to win the amount of money from a randomly choice they made... is it possible to create one?

I would appreciate very much if someone could help me with something like a "template" in order to get me started with this experiment, but any help is welcome.

Thank you for your time,

Andre

The task you are describing sounds like a Delay Discounting paradigm. Several such tasks are available in the library at https://www.millisecond.com/download/library/DelayDiscountingTask/ . Those scripts should give you a good idea about how to implement this.

Inquisit data files are simple, tab-delimited text files with an *.iqdat extension. The can be opened with / imported by any spreadsheet or statistical analysis application.

For the rating part, look at using simple <likert> trials. You can find dozens of examples via the forum search.

For the lottery part, you need to store the the choices in a <list> or <item> element at runtime and then select one of the choices randomly at the end. See e.g. https://www.millisecond.com/forums/Topic17448.aspx
