“…These observations entail that certain aspects of face identity and facial expression are analyzed separately in the human brain. Analogous suggestions have been recently put forward for human voices (Imaizumi et al, 1997). In what follows, we will examine the extent to which this dissociation can be applied to music, in the light of the results collected with our amusic patient -I.R.…”

Music and emotion: perceptual determinants, immediacy, and isolation after brain damage

1998

This study grew out of the observation of a remarkable sparing of emotional responses to music in the context of severe deficits in music processing after brain damage in a nonmusician. Six experiments were designed to explore the perceptual basis of emotional judgments in music. In each experiment, the same set of 32 excerpts taken from the classical repertoire and intended to convey a happy or sad tone were presented under various transformations and with different task demands. In Expts. 1 to 3, subjects were required to judge on a 10-point scale whether the excerpts were happy or sad. Altogether the results show that emotional judgments are (a) highly consistent across subjects and resistant to brain damage; (b) determined by musical structure (mode and tempo); and (c) immediate. Experiments 4 to 6 were designed to assess whether emotional and non-emotional judgments reflect the operations of a single perceptual analysis system. To this aim, we searched for evidence of dissociation in our brain-damaged patient, I.R., by using tasks that do not require emotional interpretation. These non-emotional tasks were a 'same-different' classification task (Expt. 4), error detection tasks (Expt. 5A,B) and a change monitoring task (Expt. 6). I.R. was impaired in these non-emotional tasks except when the change affected the mode and the tempo of the excerpt, in which case I.R. performed close to normal. The results are discussed in relation to the possibility that emotional and non-emotional judgments are the products of distinct pathways.

“…Angry voices, in particular, signal rejection and threat (Frick, 1985;Banse and Scherer, 1996). Growing evidence indicates that a network that is spatially distributed across both hemispheres contributes to the appropriate comprehension of emotional prosody (Imaizumi et al, 1997;Adolphs et al, 2002;Kotz et al, 2003;Belin et al, 2004;Wildgruber et al, 2005;Schirmer and Kotz, 2006). Above all, a bilateral frontotemporal pattern of brain activation was shown to be associated with processing emotional prosody from normal speech (Kotz et al, 2003).…”

In accordance with influential models proposing prioritized processing of threat, previous studies have shown automatic brain responses to angry prosody in the amygdala and the auditory cortex under auditory distraction conditions. However, it is unknown whether the automatic processing of angry prosody is also observed during cross-modal distraction. The current fMRI study investigated brain responses to angry versus neutral prosodic stimuli during visual distraction. During scanning, participants were exposed to angry or neutral prosodic stimuli while visual symbols were displayed simultaneously. By means of task requirements, participants either attended to the voices or to the visual stimuli. While the auditory task revealed pronounced activation in the auditory cortex and amygdala to angry versus neutral prosody, this effect was absent during the visual task. Thus, our results show a limitation of the automaticity of the activation of the amygdala and auditory cortex to angry prosody. The activation of these areas to threat-related voices depends on modality-specific attention.

“…The main finding was that the anterior temporal lobes were more active bilaterally during speaker identification than during emotion identification (Imaizumi et al 1997). A follow-up study compared a familiarity decision task on voices that were either familiar or unknown to the participants with a control phonetic decision task.…”

Voice processing in human and non-human primates

Humans share with non-human primates a number of voice perception abilities of crucial importance in social interactions, such as the ability to identify a conspecific individual from its vocalizations. Speech perception is likely to have evolved in our ancestors on the basis of pre-existing neural mechanisms involved in extracting behaviourally relevant information from conspecific vocalizations (CVs). Studying the neural bases of voice perception in primates thus not only has the potential to shed light on cerebral mechanisms that may be-unlike those involved in speech perception-directly homologous between species, but also has direct implications for our understanding of how speech appeared in humans. In this comparative review, we focus on behavioural and neurobiological evidence relative to two issues central to voice perception in human and non-human primates: (i) are CVs 'special', i.e. are they analysed using dedicated cerebral mechanisms not used for other sound categories, and (ii) to what extent and using what neural mechanisms do primates identify conspecific individuals from their vocalizations?
