About this study
Official title: Perception of Nonverbal Acoustic Signals and Resulting Physiological Responses SINOVE-PER
Like many other animals, humans produce nonverbal signals including screams, grunts, roars, cries and laughter across a variety of contexts.Due to their acoustic structure, nonverbal vocalizations and valanced speech (e.g., yelling) are also likely to elicit predictable physiological, perceptual or behavioural responses in the receiver of the signal (the listener). This is critical if researchers are to gain a comprehensive understanding of the broad range of mechanisms and the evolved functions of acoustic communication.
Therefore, in this research, investigators will examine specifically how exposure to vocal stimuli affects both the cognitive and biological responses of the listener.
Read the detailed description
Like many other animals, humans produce nonverbal 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 are likely to serve a number of important biological and social functions. In addition, human speech is characterized by nonlinguistic acoustic parameters (such as pitch, formant frequencies, and nonlinear phenomena) that are known to correlate with biologically important traits of the vocalizer.
Due to their acoustic structure, nonverbal vocalizations and valanced speech (e.g., yelling) are also likely to elicit predictable physiological, perceptual or behavioural responses in the receiver of the signal (the listener).
However, while a number of playback studies have examined behavioural responses (e.g., ratings) of listeners when exposed to various voice stimuli, very few studies have examined whether such behavioural responses are accompanied by an underlying physiological response. This is critical if researchers are to gain a comprehensive understanding of the broad range of mechanisms and the evolved functions of acoustic communication.
Therefore, in this research, investigators will examine specifically how exposure to vocal stimuli affects both the cognitive and biological responses of the listener.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Psycho-acoustic testsBehavioural
Listeners' cognitive and biological responses to vocal stimuli will be tested using psycho-acoustic tests. After listening to acoustic stimuli, participants will be asked to judge these stimuli on relevant evaluation criteria (e.g., "how distressed does this person sound?").
These stimuli might be human voices, animal voices or synthetic voices Physiological measures will be simultaneously taken using an array of complimentary, non-invasive techniques such as the Nociception Level (NOL) Index or video pupillometry
| Study group | Role | What they receive |
|---|---|---|
| Healthy adult population aged 18 to 80 years | After listening to acoustic stimuli, participants will be asked to judge these stimuli on relevant evaluation criteria (e.g., "how distressed does this person sound?"). Receives: Behavioral: Psycho-acoustic tests |
What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of correct responses in a forced-choice task after vocal stimuli
Participants will be asked to judge vocal stimuli Example : "Of the two baby cries you listened to, which one do you think shows the most distress"
Measured: Immediately after the vocal stimuli
Numerical values of judgements along a scale
Participants will be asked to judge vocal stimuli Example : participants may be asked to judge, along a gradient (from 0 to 100), "how consistent the distress of the baby you heard is to you".
Measured: Immediately after the vocal stimuli
Response time (second)
Participants will be asked to judge vocal stimuli In this case, the participant is instructed to respond as soon as possible. The response time for each stimulus is then systematically measured
Measured: Immediately after the vocal stimuli
Secondary outcomes (5)
Heart rate (bpm)
Measured: During the vocal stimuli
Skin conductance (Siemens)
Measured: During the vocal stimuli
Skin temperature (°C)
Measured: During the vocal stimuli
Nociception Level Index (NOL)
A non-invasive finger probe, containing four sensors, will be placed on the on the index finger of the participants.
Measured: During the vocal stimuli
Pupillary diameter (millimeter)
Using a high resolution binocular for automated pupil diameter measurement with an infrared camera
Measured: During the vocal stimuli
