How does trust sound? The influence of voice pitch on trust
Trust is a building block of society. It is shaped by different types of information such as contextual cues or facial appearance. One of such information is voice pitch, that is how high or how low voice sounds. Previous research showed that voice pitch influenced perceptions of trust. Yet studies investigating the effect of voice pitch on trust mostly relied on perceptual measures of trust or hypothetical decision-making tasks. To overcome these limitations, I plan to use a twist of the “Trust game” paradigm (Berg et al., 1995), which measures trust on a behavioral level, to test the hypothesis that voice pitch is information that shapes trust. The twist of the Trust game will allow experimentally manipulating voice pitch and link it to a behavioral measure of trust with real consequential outcomes. With this presentation, I seek your feedback on the study design to improve it before running it.
