Vocal bursts are non-linguistic affectively-laden sounds with a crucial function in human communication, yet their affective structure is still debated. Studies showed that ratings of valence and arousal follow a V-shaped relationship in several kinds of stimuli: high arousal ratings are more likely to go on a par with very negative or very positive valence. Across two studies, we asked participants to listen to 1,008 vocal bursts and judge both how they felt when listening to the sound (i.e. core affect (...) condition), and how the speaker felt when producing it (i.e. perception of affective quality condition). We show that a V-shaped fit outperforms a linear model in explaining the valence-arousal relationship across conditions and studies, even after equating the number of exemplars across emotion categories. Also, although subjective experience can be significantly predicted using affective quality ratings, core affect scores are significantly lower in arousal, less extreme in valence, more variable between individuals, and less reproducible between studies. Nonetheless, stimuli rated with opposite valence between conditions range from 11% (study 1) to 17% (study 2). Lastly, we demonstrate that ambiguity in valence (i.e. high between-participants variability) explains violations of the V-shape and relates to higher arousal. (shrink)

Justin D’Arms and Daniel Jacobson have argued that to evaluate the funniness of a joke based on the consideration of whether it is morally appropriate to feel amused commits the “moralistic fallacy.” We offer a new and empirically informed reply. We argue that there is a way to take morality into consideration without committing this fallacy, that is, it is legitimate to say that for some people, witty but immoral jokes can fail to be funny because they are immoral. In (...) our account, one has an intramural moral reason not to feel amused if one focuses on the moral feature itself of a joke rather than the moral consequence implied in one’s reaction to the joke. When one judges a joke as not funny because of the intramural moral reason, one is in a negative emotional state with high arousal, for example, moral disgust or anger. This state is psychologically incompatible with amusement. That one has an intramural reason not to feel amused thus implies that one does not have a reason to feel amused. Moral consideration thus plays an indirect and appropriate role in the evaluation of the funniness of a joke. (shrink)
