Article Abstract

Purpose: The comprehension of emotions through speech, known as affective prosody comprehension, is an ability that decreases with healthy aging. Affective prosody comprehension is underpinned by three cognitive components (perceptual, lexical, and semantic). However, no data indicate which one(s) is/are impacted by aging. Affective prosody comprehension is based on the analysis of the emotional state of our interlocutor. However, it is still unknown if psycholinguistic variables permitting to access this emotional state such as emotion category, valence, or arousal impact affective prosody comprehension abilities differently according to age. This study aims to investigate the impacts of aging on affective prosody comprehension abilities, exploring the links with the underlying cognitive components and psycholinguistic variables.

Method: Sixty healthy adults were recruited: 30 younger (18-35 years old) and 30 older individuals (63+ years old). Participants completed a general task of affective prosody comprehension and three specific tasks each evaluating an underlying cognitive component (perceptual, lexical, semantic).

Results: Older adults showed a decreased performance in general affective prosody comprehension abilities and in lexical abilities specifically in comparison with younger adults. Also, psycholinguistic variables such as emotion category and arousal played a role in the decreased performance of older adults.

Conclusion: These results constitute an additional advancement in understanding the normal functioning of affective prosody comprehension processes.

Despite a large body of literature on the psychological and brain mechanisms of vocal emotion perception, less is known on expression and production mechanisms, especially the vibrations originating in the vocal cords and their role in emotional voice production. In the present study, we aimed to fill this gap. Participants were asked to produce angry, happy and neutral tone emotional vocalizations in different production conditions ('normal', 'whisper', 'silent articulation').

: Successful discourse relies not only on linguistic but also on prosodic information. Difficulty recognizing emotion conveyed through prosody (receptive affective aprosodia) following right hemisphere stroke (RHS) significantly disrupts communication participation and personal relationships. Growing evidence suggests that damage to white matter in addition to gray matter structures impairs affective prosody recognition.

Some studies indicate enhanced vocal emotion recognition and emotional prosody perception in musicians. Music perception has been linked to emotion processing. Collective music making has been found to rely on responding to and sharing the emotions of others.

Humans and other animals communicate a large quantity of information vocally through nonverbal means. Here, we review the domains of animal vocalizations, human nonverbal vocal communication and computer-mediated communication (CMC), under the common thread of emotion, which, we suggest, connects them as a dimension of all these types of communication. After reviewing the use of emotions across domains, we focus on two concepts that have often been opposed to emotion in the animal versus human communication literature: control and meaning.
