Affect perception is measured on arousal and valence dimensions rather than emotion labels
Evidence
Affect perception was tested using the dimensional approach, in which participants indicate the level of the emotion dimensions arousal (calm vs. aroused) and valence (positive vs. negative attitude), separately on a rating scale (rather than labeling emotion categories such as “angry” or “sad”). … Given the close relationship between German and Swiss German, the way affect is encoded in Swiss German is not expected to differ considerably from that in German as spoken in Germany. The corpus comes with mean reference values for the degree of arousal and valence for each utterance. These reference values had been collected with a 5-step pictorial rating tool (Bradley and Lang 1994 ), ranging from ‑1 (calm/negative) to + 1 (aroused/positive). … All stimuli in our experiment were neutral regarding the content of what was said (e.g. ‘Was hast du getan ?’ ‘What have you done?’) to minimize semantic interference, were shorter than 3 s and were produced by multiple speakers. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1357
