| What can a wide eyed,talking robot teach us about trust? A lot,according to Northeastern psychology professor David DeSteno, and his colleagues, who are conducting a research to determine how humans decide to trust strangers. The interdisciplinary(跨学科的) research project,funded by the National Science Foundation (NSF) , is being conducted together with Cynthia Breazeal,director of the MIT Media Lab's Personal Robots Group, Robert Frank,an economist,and David Pizarro,a psychologist,both from Cornell. The researchers are examining whether gestures could affect our trustworthiness judgments."People tend to mimic(模仿)each other's body language,"said DeSteno,"which might help them develop intuitions (直觉) about what other people are feeling." This project tests their theories by having humans interact with the social robot,Nexi,in an attempt to judge her trustworthiness.Without knowing the participants,Nexi has been programmed to make gestures while speaking with selected participants-gestures that the team thinks could determine whether or not she's considered trustworthy. During the first part of the experiment, Nexi makes small talk with them for 10 minutes, asking and answering questions about topics such as traveling,where they're from and what they like most about living in Boston. "The goal was to create a normal conversation with accompanying movements to see what the mind would intuitively(直觉地) collect about the trustworthiness of another,"said DeSteno. The participants then play an economic game called "Give Some",which asks them to determine how much money Nexi might give them at the expense of her individual profit.Meanwhile,they decide how much,if any,they'll give to Nexi.The rules of the game allow for two distinct outcomes:higher individual profit for one and loss for the other,or relatively smaller and equal profits for both partners. "Trust mightn't be determined by only one gesture,but rather a 'dance' that happens between the strangers,which leads them to trust or not trust the other," said DeSteno,who will continue testing their theories by seeing if Nexi can be taught to predict the trustworthiness of human partners. |
