Overview
Like many other animals, humans produce nonverbal vocal signals including screams, grunts, roars, cries and laughter across a variety of contexts. However, despite their importance in the human vocal repertoire, the mechanisms and functions of non-verbal signals remain little studied and poorly understood in humans.Our studies aim to improve our understanding of the nature and function of non-verbal signals.
Detailed description
Like many other animals, humans produce nonverbal vocal signals including screams, grunts, roars, cries and laughter across a variety of contexts. Many of these signals (such as cries) are already produced at birth and likely serve a number of important biological and social functions. In addition, human speech is characterised by nonlinguistic acoustic parameters (such as pitch, formant frequencies, and nonlinear phenomena) that are known to correlate with biologically important traits of the vocalizer.
However, despite their importance in the human vocal repertoire, the mechanisms and functions of non-verbal signals remain little studied and poorly understood in humans.
Theses studies aim to improve the understanding of the nature and function of non-verbal signals. Thus, this study is part of a long-term research project in which investigators are trying to clarify the information contained in the acoustic structure of human non-verbal signals, and to investigate the factors influencing their production.
Interventions
- Behavioral Production of vocal sounds
Participants will be asked to produce vocal sounds of different nature according to the non-verbal parameters of interest for the given study. For example, they can read a script containing vowels ('a', 'e', 'i', 'o', 'u'), short sentences ('hello, how are you'), longer passages of standardised reading texts, and can also be asked to speak freely about any topic ('freedom of speech'). They can be asked to play a role or to imitate a particular emotional state. For example, "imagine that you hav
Primary outcome measures
- Vocal analysis [Time frame: During the vocal production]
Secondary outcome measures (5)
- Heart rate (bpm) [Time frame: During the vocal production]
- Skin conductance (Siemens) [Time frame: During the vocal production]
- Skin temperature (°C) [Time frame: During the vocal production]
- Nociception Level Index (NOL) [Time frame: During the vocal production]
- Pupillary diameter (millimeter) [Time frame: During the vocal production]
