currently I'm trying to set up an experiment in which affective stimuli are presented to participants. Before those stimuli are shown, I want the subjects to prerate the stimuli on a scale from 1 to 10. After they've done this, I want to select the four best and the four worst rated stimuli for each participant to use these preselected stimuli in the actual study.
Unfortunately, I have no idea how to get the collected data from the preselection task (which should be stored by a logger), choose the four best and worst stimuli and present only these ones to the subject.
Maybe someone can help me with this problem?
Thanks a lot!
