List of affective states for a study? I am putting together a study that attempts to assess whether people assign particular affective or emotional states to images--specifically, animated GIFs. Is there a "standard" list of emotional states that has been used in research before, or that tends to be favored by researchers who study emotions? I'm considering something like Plutchik's three-dimensional circumplex model, but I didn't know if there was something else that tended to be more favored.
There are a range of "adjective checklists" that have been developed to assess affective states, personality traits, or characteristics of individuals. Two of the most widely cited measures are the Multiple Affective Adjective Check List (MAACL) and the Multiple Affective Adjective Checklist-Revised (MAACL-R) (Zuckerman &amp; Lubin, 1965; Zuckerman &amp; Lubin, 1985). Although the actual MAACL-R manual may require purchase, lists of the affective items are available in other publications (Gotlib &amp; Meyer, 1986). 

Clinically, I have used the How Do I Feel Right Now? chart for clients who have difficulty identifying and naming their emotional states (http://blogs.oregonstate.edu/careerservices/2012/11/30/emotional-intelligence-what-is-it-and-why-do-employers-want-emotionally-intelligent-employees/). 

Other sources of emotion lists in the field of psychology include:
