How to individualise an IAT-experiment

Joolz — Thu, 14 Apr 2016 09:36:12 GMT

Hello to all of you!

On behalf of my master thesis I am dealing with my very first Inquisit skript at the moment.
Until now my personal challenge has been surprisingly successful, but now I am trying to
individualise a set of pictures that should be presented during an IAT-Experiment.

Therefor I implemented a 9-point-likert-scale on which participant should rate the picture
material. Now I wish to "tell" my skript to choose 16 pictures out of that, the eight pictures
with the highest ratings and the eight pictures with the lowest.

For example if the picture ratings of a participant would look like this...

1 1 1 1 1 1 1 2 2 2 3 3 4 4 4 5 5 5 5 5 6 6 6 7 7 7 8 8 9

... I´d like Inquisit to use the pictures that belong to the ratings 1 1 1 1 1 1 1 2 for the first IAT category and
the pictures that belong to the likert-ratings 9 8 8 7 7 7 6 6 for the other category.

Does someone have any idea how I could implement this in my script? I would be very thankful about any advice!!!

Thank you very much in advance!!!

Here some relevant scripting from my experiment. It might look like a mess to you, my appologies. I´ve never done any programmling before...
