I’m currently running an affective priming task in which a food stimuli appears on the screen before being replaced by a positive or negative word. Participants then have to identify whether the word is positive or negative.
To ensure that all healthy and unhealthy food stimuli are presented with both a positive and a negative word I have structured the task like this:
I set the loop to random however the presentation is not random.
For example the presentation will look something like this:
- Grapes… happy
- Grapes… sad
- Brownie… happy
- Brownie… sad
- Strawberries… friendship
- Strawberries… loneliness
Is anyone able to advise on how to make this more random?
Primarily, not present the same food one after the other, and secondly not always be a positive word followed by a negative word.
