The Voice of Anger: Oscillatory EEG Responses to Emotional Prosody.

ABSTRACT: Emotionally relevant stimuli and in particular anger are, due to their evolutionary relevance, often processed automatically and able to modulate attention independent of conscious access. Here, we tested whether attention allocation is enhanced when auditory stimuli are uttered by an angry voice. We recorded EEG and presented healthy individuals with a passive condition where unfamiliar names as well as the subject's own name were spoken both with an angry and neutral prosody. The active condition instead, required participants to actively count one of the presented (angry) names. Results revealed that in the passive condition the angry prosody only elicited slightly stronger delta synchronization as compared to a neutral voice. In the active condition the attended (angry) target was related to enhanced delta/theta synchronization as well as alpha desynchronization suggesting enhanced allocation of attention and utilization of working memory resources. Altogether, the current results are in line with previous findings and highlight that attention orientation can be systematically related to specific oscillatory brain responses. Potential applications include assessment of non-communicative clinical groups such as post-comatose patients.

Project description:Purpose: Cochlear implants (CIs) provide reasonable levels of speech recognition quietly, but voice pitch perception is severely impaired in CI users. The central question addressed here relates to how access to acoustic input pre-implantation influences vocal emotion production by individuals with CIs. The objective of this study was to compare acoustic characteristics of vocal emotions produced by prelingually deaf school-aged children with cochlear implants (CCIs) who were implanted at the age of 2 and had no usable hearing before implantation with those produced by children with normal hearing (CNH), adults with normal hearing (ANH), and postlingually deaf adults with cochlear implants (ACI) who developed with good access to acoustic information prior to losing their hearing and receiving a CI. Method: A set of 20 sentences without lexically based emotional information was recorded by 13 CCI, 9 CNH, 9 ANH, and 10 ACI, each with a happy emotion and a sad emotion, without training or guidance. The sentences were analyzed for primary acoustic characteristics of the productions. Results: Significant effects of Emotion were observed in all acoustic features analyzed (mean voice pitch, standard deviation of voice pitch, intensity, duration, and spectral centroid). ACI and ANH did not differ in any of the analyses. Of the four groups, CCI produced the smallest acoustic contrasts between the emotions in voice pitch and emotions in its standard deviation. Effects of developmental age (highly correlated with the duration of device experience) and age at implantation (moderately correlated with duration of device experience) were observed, and interactions with the children's sex were also observed. Conclusion: Although prelingually deaf CCI and postlingually deaf ACI are listening to similar degraded speech and show similar deficits in vocal emotion perception, these groups are distinct in their productions of contrastive vocal emotions. The results underscore the importance of access to acoustic hearing in early childhood for the production of speech prosody and also suggest the need for a greater role of speech therapy in this area.

Project description:This study examined production and perception of affective prosody by adults with autism spectrum disorder (ASD). Previous research has reported increased pitch variability in talkers with ASD compared to typically developing (TD) controls in grammatical speaking tasks (e.g., comparing interrogative vs. declarative sentences), but it is unclear whether this pattern extends to emotional speech. In this study, speech recordings in five emotion contexts (angry, happy, interested, sad, and neutral) were obtained from 15 adult males with ASD and 15 controls (Experiment 1), and were later presented to 52 listeners (22 with ASD) who were asked to identify the emotion expressed and rate the level of naturalness of the emotion in each recording (Experiment 2). Compared to the TD group, talkers with ASD produced phrases with greater intensity, longer durations, and increased pitch range for all emotions except neutral, suggesting that their greater pitch variability was specific to emotional contexts. When asked to identify emotion from speech, both groups of listeners were more accurate at identifying the emotion context from speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural. Collectively, these results reveal differences in emotional speech production in talkers with ASD that provide an acoustic basis for reported perceptions of oddness in the speech presentation of adults with ASD. Autism Res 2017, 10: 1991-2001. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.This study examined emotional speech communication produced and perceived by adults with autism spectrum disorder (ASD) and typically-developing (TD) controls. Compared to the TD group, talkers with ASD produced emotional phrases that were louder, longer, and more variable in pitch. Both ASD and TD listeners were more accurate at identifying emotion in speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural.
