If a little humanlike robot begged you not to shut it off,
would you show sympathy?
In an experiment {#blank#}1{#/blank#} (intend) to find out how people treat robots
when they act like humans, many participants struggled to power down a begging
robot named Nao. {#blank#}2{#/blank#} experiment was conducted by researchers in
Germany, whose findings {#blank#}3{#/blank#} (publish) in the scientific journal PLOSOne.
Nao, {#blank#}4{#/blank#} was designed to beg about half of the
participants not to switch it off but not the other half, was used {#blank#}5{#/blank#} (measure) if his begging affected how people
reacted.
In one previous experiment, researchers
found that people preferred communicating with robots with complementary (互补的) personality characteristics to {#blank#}6{#/blank#} (they) own. And since robots can exhibit
social characteristics either {#blank#}7{#/blank#} (speak) with human voices or taking the shape
of a human body, the research suggests that people tend to react “{#blank#}8{#/blank#} (especial) social to them.”
The researchers said a possible {#blank#}9{#/blank#} (explain) for their results was that people
regarded Nao's begging {#blank#}10{#/blank#} “a sign of making its own decision.”
