What are you trying to achieve?:
I’m working for a simple experiment for my undergraduate thesis.
I need to show for X time a set of neutral / negative pictures but after every pictures I have to show 2 other pictures with a particular meaning and my subjects have to pick one.
It’s pretty easy but I have to satisfy these requirement:
- After a negative picture, I’m going to show only food pictures vs caring pictures.
- After a neutral one, I’m going to show food pictures vs caring pictures or neutral pictures vs neutral pictures.
I need to randomize stimuli ( neutral and negative) but setting that every time Neg is on screen, after that should follow food vs caring. For neutral is good to randomize food vs caring with neutral vs neutral.
At this moment i’m stuck at experiment design on builder.
On excel I set these parameters:
stimuli: negative and neutral pictures
label: each file are labelled or neg or neutral
id_1: all of the food pictures
id_2: all of the caring pictures
id_3: the other set of neutral pictures
rand: randomization column
my idea is to make a big loop, split in two the stimuli and set that they should be random.
Every stimuli should have a loop that respect my requisites.
but it looks reaaally messy. Any idea to make a clean work?
Thank you so much
