The PXLab Self-Assessment-Manikin Scales

These scales are modified versions of the Self-Assessment-Manikin scales developed by Lang (1980). These are the modifications:

• All images are scalable vector drawings.
• The Valence and the Dominance scale are continuous scales.
• The Arousal scale exists as a 5-, 7-, and 9-point scale.
• The Dominance scale satisfies Weber's law for area.
• The Valence scale also exists as a portrait version as first used by Suk (2006).

Self-Assessment-Manikin Scales Example Application

The file sam.pxd shows several Self-Assessment-Manikin scales (Lang, 1980) combined with text, color and image objects. Scale variants are: 5, 7, and 9 point scales. The 9-point scale my be shown in a reduced form using only 5 images and seperate selection dots. The valence scale my be shown in full body or portrait mode. All images are scalable and can be fit to any size.
