Perception of Nonverbal Acoustic Signals and Resulting Physiological Responses (SINOVE-PER)

Plain-language summary

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.
