Confusion, concentration, and other emotions of interest: Commentary on Rozin and Cohen (2003).

P. Rozin and A. B. Cohen's (2003) method of sending students out to observe each other in familiar circumstances undoubtedly exaggerated the apparent prevalence of confusion, concentration, and worry. The expressions they observed probably ranged from regulatory feedback and communicative signals to expressions of the "intellectual emotions" described by C. Darwin (1872/1965). Appraisal theories can easily accommodate these affective states; there is no need to postulate new "basic emotions" unless one adheres to a rigid categorical view of emotion. Finally, Rozin and Cohen have made a valuable contribution by reminding us of the importance of emotions related to interest.
