When Brain Differentiates Happy from Neutral in Prosody ? ISCA

چکیده
The effect of different intensities of vocal emotion on event related potentials has yet not been studied. We therefore investigated 16 healthy participants with emotion and sound decision on neutral and happy voice which varied continuously in intensity. The result found that neutral and happy voice can be differentiated on P2 component under both explicit and implicit condition. Moreover, the P2 parameters were linear correlated with the rate of happiness, suggesting a graded processing of vocal emotion in early stage. However, the brain distinguished neutral from happy in P3 interval when performing explicit task but exhibit a categorical feature.

Recruitment of Language-, Emotion- and Speech-Timing Associated Brain Regions for Expressing Emotional Prosody: Investigation of Functional Neuroanatomy with fMRI
We aimed to progress understanding of prosodic emotion expression by establishing brain regions active when expressing specific emotions, those activated irrespective of the target emotion, and those whose activation intensity varied depending on individual performance. BOLD contrast data were acquired whilst participants spoke non-sense words in happy, angry or neutral tones, or performed jaw-...
متن کاملEmotional prosody perception and its association with pragmatic language in school-aged children with high-function autism.
Emotional prosody perception is essential for social communication, but it is still an open issue whether children with high-function autism (HFA) exhibit any prosodic perception deficits or experience selective impairments in recognizing the prosody of positive emotions. Moreover, the associations between prosody perception, pragmatic language, and social adaptation in children with HFA have n...
متن کاملThe Developmental Origins of Voice Processing in the Human Brain
In human adults, voices are processed in specialized brain regions in superior temporal cortices. We examined the development of this cortical organization during infancy by using near-infrared spectroscopy. In experiment 1, 7-month-olds but not 4-month-olds showed increased responses in left and right superior temporal cortex to the human voice when compared to nonvocal sounds, suggesting that...

The present electroencephalographic (EEG) study investigated the ability of cochlear implant (CI) users to recognize emotional prosody. Two CI speech-processing strategies were compared: the ACE (Advance Combination Encoder) and the newly developed MP3000. Semantically neutral sentences spoken in three different emotional prosodies (neutral, angry, happy) were presented to 20 post-lingually dea...
متن کاملImplicit processing of emotional prosody in a foreign versus native language
To test ideas about the universality and time course of vocal emotion processing, 50 English listeners performed an emotional priming task to determine whether they implicitly recognize emotional meanings of prosody when exposed to a foreign language. Arabic pseudoutterances produced in a happy, sad, or neutral prosody acted as primes for a happy, sad, or ‘false’ (i.e., non-emotional) face targ...
