Dear Inquisit Forum,
I am running a relatively simple task - which is also my first go at Inquisit programming.
The aim of the task is to present a series of images (in this case 240 foods) and for each image ask the same question with a likert scale, with each image being presented once and with the order selected at random. I have coded this for 3 images, and it is very straight-forward (see my code for the block in question below).
My question is: is there an alternative to typing out every single picture filename under <item foods> in the code at the outset? This is both tedious and error prone, and seems to be an inefficient way to code.
All the images are named with numbers ("001.bmp", "002.bmp", "003.bmp" .... "240.bmp")
There are a number of ways I can think of doing this (from my experience with other testing programming)
- To have the item list populated at runtime using a loop and adding a filename at each run through the loop, being limited by how many files to look for.
- To specify a folder from which to populate the item list.
- To evaluate an expression on each trial that determines the picture filename during runtime, for example using / item = ("<% counter.foods.currentvalue %>.bmp") and with a counter selecting a number from 1 to 240 at random on each trial.
I have explored all three - and think they are all impossible with Inquisit. Can anyone with more experience suggest what would be possible? I am currently considering writing a piece of code elsewhere to make sure I write the list with no syntax errors!
If it is relevant, the task is going to be run using Inquisit Web 3.0.
Many thanks for you help, and if there is more information I can provide, please ask.
The code for the block of Likert trials I am using is pasted below (in this case with only 3 food images):
/ trials = [1-3 = Health]
/1 = "001.bmp"
/2 = "002.bmp"
/3 = "003.bmp"
/ size = (500, 500)
/ items = foods
/ position = (50, 50)
/ select = noreplace
/ items = ("How healthy is this food?")
/ position = (50,10)
/ anchors = [1="very unhealthy"; 5="very healthy"]
/ stimulusframes = [1 = foodpicture, HealthQ]
/ position= (50, 90)
/font = ("Arial", -16, 400, 0, 49)
Please can you rate how HEALTHY you think the follow foods are on a scale from 1 (very unhealthy) to 5 (very healthy).^^^^
