With a view to measuring subjective experience of mixed emotions, we designed an Analogical Emotional Scale (AES). This scale permits the analysis of how, at the subjective level, the emotions evolve from the beginning to the end of the experience, allowing discrimination between simultaneous mixed emotional experiences (i. e., two emotions taking place at the same time) and sequential mixed emotional experiences (i. e., two emotions switching rapidly back and forth). In Study 1 we asked participants to recall a naturally occurring situation, in Study 2 we induced simple vs. mixed emotions in a controlled situation, and in Study 3 we manipulated the structure of emotional stimuli, sequential versus simultaneous. The results showed that the combined use of rating scales and the AES permits us to obtain a more accurate estimation of the actual presence of simultaneous mixed emotional experiences.
