This script implements a simple picture rating script that uses the Self Assessment Manikin Pictorial Rating Scale described in:
Bradley, M. & Lang, P.J. (1994). Measuring Emotion: The Self-Assessment Manikin and The Semantic Differential. J. Behav. Ther. Exp. Psychiat, 25, 49-59.
2 minutes
Participants are shown 8 pictures (one at a time) and are asked to rate the emotions these pictures elicit on three dimensions: valence, arousal, dominance. The rating scales consist of a series of pictorial depictions of a manikin displaying those emotions. This script runs a 9-point scale: 5 picture anchors with spaces in between
This script implements a simple demonstration to use the Self Assessment Manikin Scales for picture ratings.
• 8 trials (the order of the images is determined randomly)
this script automatically adapts to run more/fewer trials if the number of images is changed
under item.images.
• participants need to select one of the response boxes for each of the three dimensions (valence, arousal, dominance)
There are 5 picture anchors and 4 empty boxes in between (=9 anchor points)
provided by Millisecond - can be edited under section Editable Stimuli
the script runs as many self-assessment trials as there are images provided under item.images.
By default, the script runs 8 trials.
