Results and Comments
The UMACL is an elaboration of Thayer’s (1989) AD-ACL and shares the strengths of that instrument in asses-
sing subjective arousal in a variety of experimental and field settings. The inclusion of a Hedonic Tone scale pro-
vides more comprehensive coverage of mood. The supplementary Anger-Frustration scale is not well
distinguished from low Hedonic Tone psychometrically ( Matthews et al., 1990a ), but it may be useful in studying
certain issues, such as driver aggression ( Matthews, 2002 ).
