“…Neuroimaging studies in healthy subjects suggest that, similar to music, affective prosody perception involves a network of right frontotemporal and bilateral frontal regions and pathways (Wildgruber et al, 2006;Frühholz et al, 2015). Interestingly, congenital amusics have been found to have subtle deficits in perceiving affective prosody (Thompson et al, 2012;Lima et al, 2016). Also in stroke patients, affective aprosodia has been linked to right hemisphere damage (Ross and Monnot, 2008;Ross, 2010;Jafari et al, 2017), but the precise neural relationship between amusia and aprosodia has never been systematically mapped; this would be an interesting and fruitful topic for future research.…”

Acquired amusia provides a unique opportunity to investigate the fundamental neural architectures of musical processing due to the transition from a functioning to defective music processing system. Yet, the white matter (WM) deficits in amusia remain systematically unexplored. To evaluate which WM structures form the neural basis for acquired amusia and its recovery, we studied 42 stroke patients longitudinally at acute, 3-month, and 6-month post-stroke stages using DTI [tract-based spatial statistics (TBSS) and deterministic tractography (DT)] and the Scale and Rhythm subtests of the Montreal Battery of Evaluation of Amusia (MBEA). Non-recovered amusia was associated with structural damage and subsequent degeneration in multiple WM tracts including the right inferior fronto-occipital fasciculus (IFOF), arcuate fasciculus (AF), inferior longitudinal fasciculus (ILF), uncinate fasciculus (UF), and frontal aslant tract (FAT), as well as in the corpus callosum (CC) and its posterior part (tapetum). In a linear regression analysis, the volume of the right IFOF was the main predictor of MBEA performance across time. Overall, our results provide a comprehensive picture of the large-scale deficits in intra- and interhemispheric structural connectivity underlying amusia, and conversely highlight which pathways are crucial for normal music perception.

“…Lolli et al recruited amusics based on their pitch discrimination threshold, whereas Thompson et al recruited amusics based on the three MBEA pitch subtests (scale, interval, contour). To further explore the potential auditory emotion processing deficit in amusia, Lima et al (2016) investigated amusics' emotion recognition not only in speech, but also in non-verbal auditory stimuli. Participants heard non-verbal vocalizations (e.g.…”

Emotional prosody in congenital amusia: Impaired and spared processes

et al. 2019

Congenital amusia is a lifelong deficit of music processing, in particular of pitch processing. Most research investigating this neurodevelopmental disorder has focused on music perception, but pitch also has a critical role for intentional and emotional prosody in speech. Two previous studies investigating amusics' emotional prosody recognition have shown either some deficit or no deficit (compared to controls). However, these previous studies have used only long sentence stimuli, which allow for limited control over acoustic content. Here, we tested amusic individuals for emotional prosody perception in sentences and vowels. For each type of material, participants performed an emotion categorization task, followed by intensity ratings of the recognized emotion. Compared to controls, amusic individuals had similar recognition of emotion in sentences, but poorer performance in vowels, especially when distinguishing sad and neutral stimuli. These lower performances in amusics were linked with difficulties in processing pitch and spectro-temporal parameters of the vowel stimuli. For emotion intensity, neither sentence nor vowel ratings differed between participant groups, suggesting preserved implicit processing of emotional prosody in amusia. These findings can be integrated into previous data showing preserved implicit processing of pitch and emotion in amusia alongside deficits in explicit recognition tasks. They are thus further supporting the hypothesis of impaired conscious analysis of pitch and timbre in this neurodevelopmental disorder.

“…These stimuli have been used frequently in behavioral and neuroimaging studies (Lavan et al, 2015;Lavan et al, 2016;Lima et al, 2016a;O'Nions et al, 2017). The final set included a similar number of vocalizations produced by men and women, and it was selected from a larger pool of stimuli based on a pilot perceptual validation study (N = 26 listeners, none of which took part in the main study).…”

Authentic and Posed Emotional Vocalizations Trigger Distinct Facial Responses

The ability to recognize the emotions of others is a crucial skill. In the visual modality, sensorimotor mechanisms provide an important route for emotion recognition. Perceiving facial expressions often evokes activity in facial muscles and in motor and somatosensory systems, and this activity relates to performance in emotion tasks. It remains unclear, however, whether and how similar mechanisms extend to audition. To address this issue, we examined facial electromyographic and electrodermal responses to nonverbal vocalizations that varied in emotional authenticity. Participants (N = 100) passively listened to laughs and cries that could reflect a genuine or a posed emotion. Bayesian mixed models indicated that listening to laughter evoked stronger facial responses than listening to crying. These responses were sensitive to emotional authenticity. Genuine laughs evoked more activity than posed laughs in the zygomaticus and orbicularis, muscles typically associated with positive affect. We also found that activity in the orbicularis and corrugator related to performance in a subsequent authenticity detection task. Stronger responses in the orbicularis predicted improved recognition of genuine laughs. Stronger responses in the corrugator, a muscle associated with negative affect, predicted improved recognition of posed laughs. Moreover, genuine laughs elicited stronger skin conductance responses than posed laughs. This arousal effect did not predict task performance, though. For crying, physiological responses were not associated with authenticity judgments. Altogether, these findings indicate that emotional authenticity affects peripheral nervous system responses to vocalizations. They point to a role of sensorimotor mechanisms in the evaluation of authenticity in the auditory modality.
