PANAS positive activation is associated with anger.

As a prototypic negative emotion, anger would seem to have little in common with positive activation, as measured by the Positive and Negative Affect Schedule (PANAS; D. Watson, L. A. Clark, & A. Tellegen, 1988). However, growing evidence suggests that both anger and positive affect are associated with approach motivation. This suggests the counterintuitive hypotheses that positive affect should be increased by anger-evoking situations, and that positive affect and anger should be directly correlated in such situations. Four studies tested and supported these hypotheses. Discussion focuses on the implications of these results.
