Abstract
Past literature have found that people could infer traits and characteristics of the speaker just by hearing the voice. There have also been studies that found that different types of voices could elicit different decision making behaviours. However, the effect of children's voice on people's decision making have been rarely studied. Hence, this study aims to fill this gap by studying how children's voice could influence ones' intertemporal decision making. All participants will make a series of binary decisions in a standard time preference task, choosing between an immediate, smaller reward, versus a delayed larger reward. However, the type of voice that will hear the description of the delayed rewards will depend on the condition that they are randomly assigned to. Those in the Child condition will hear the delayed rewards being described using a child voice while those in the Adult condition will hear the same delayed rewards being described using an adult voice.

Experimental Design

effects.
Experimental Design Details
The study will recruit approximately 500 English monolingual subjects on Prolific. Participants will be randomly assigned to either Child or Adult condition (i.e., 250 participants in each treatment arm). Participants will make a series of binary decisions in a standard time preference task, choosing between an immediate, smaller reward, versus a delayed larger reward. In the Child condition, the delayed rewards will be read using a Child's voice while in the Adult condition, the delayed rewards will be read using an Adult's voice. After participants complete the time preference task, they will be
asked to fill in an exit survey.
Randomization Method
Randomization is done by computer.
Randomization Unit
Randomization takes place at the individual level.
Was the treatment clustered?
No
