All uses of the GEMS (including adaptions and developments) for commercial purposse are prohibited. 


In your application, please indicate which of the three GEMS-scales you would like to use in your project.

  • The GEMS-45 is the original, full-length scale and has 45 items. Each of the 9 GEMS emotion factors is assessed by an average of 5 items.
  • The GEMS-25 is the brief version of the GEMS-45 and has 25 items. All 9 GEMS emotion factors can be measured, most of them by 3 items. The GEMS-25 is based on the same adjective items pool and data-analytic procedures reported in our original article. Although striking a reasonable balance between validity and practicality, the GEMS-25 is not suited for work intending to explore or test the factorial structure of musically evoked emotion.
  • The GEMS-9 just presents the primary 9 factors along with a few emotion adjectives describing each factor. We have added this ultra-short version because sometimes researchers need to collect data in a very short amount of time (e.g., in the brain scanner). From a psychometric point of view, however, it is preferable to have multiple items tapping a given factor as in the full-length and the short version of our scales (GEMS-45 & GEMS-25).
