I was required to read one of Bernie Siegel's books in college and was hooked on his positivity from that moment on. The stories of his unconventional1and the exceptional patients he wrote about were so2 to me and had such a big3on how I saw life from then on.

    Who knew that so many years later I would look to Dr. Bernie and his CDs again to4my own cancer experience?

    I'm an ambitious5, and when I started going through chemo(化疗), even though I'm a very6 person, I lost my drive to write. I was just too tired and not in the7. One day, while waiting to go in for8, I had one of Dr. Bernie's books in my hand. Another patient9what I was reading and struck up a conversation with me10 he had one of his books with him as well. It11that among other things, he was an eighty-year-old writer. He was 12a published author, and he was currently13on a new book.

    We would see each other at various times and14friends. Sometimes he wore a duck hat, and I would tell myself, he was definitely a(n) 15of Dr. Bernie. He really put a 16on my face. He unfortunately17 last year due to his cancer,18he left a deep impression on me and gave me the 19 to pick up my pen again. I20to myself, "If he can do it, then so can I."

    A new study from the Georgia Institute of Technology finds that older and younger people have a varying preference for what they would want a personal robot to look like. And they change their minds based on what the robot is supposed to do.

    Participants were shown a series of photos, either robotic, human or mixed human-robot faces, and were asked to select the one that they would prefer for their robot's appearance. Most college-aged adults in the study preferred a robotic appearance, although the others were also generally open to them. However, nearly 60 percent of older adults said they would want a robot with a human face, and only 6 percent of them chose one with a mixed human-robot appearance.

    "We found that participants, both younger and older, will assign emotional traits to a robot based on its face, which will determine what they are most comfortably interacting with," Akanksha Prakash, a psychology graduate student at Georgia Tech who led the study, said in a statement. So when participants were told the robot was helping with personal care, chores, social interaction or helping to make decisions, something interesting happened.

    Preference was less strong for helping with chores, although the majority of older and younger participants chose a robot with a robotic face. But for decision-making tasks, such as getting advice on where to invest money, younger participants tended to select a mixed human-robot appearance. A robotic face was their least favored choice for this task. Older adults generally preferred a human face. Personal care tasks such as bathing caused the most divisive preferences within both age groups. Those who chose a human face did so because they associated the robot with human-like care capabilities — such as nursing — and trustworthy traits. Many others didn't want anything looking like a human to bathe them due to the private nature of the task.

    Based on this early research, the researcher says that if a robot is designed to help only with a specific task, its appearance should fit in with the task. For instance, if the robot is designed to specifically assist the user with critical decisions, the robot should be given an intelligent look instead of a funny one. However, if the robot is tasked with a variety of jobs in the home, allowing for appearance customizability(可定制性) might be the best option.

    The researcher next plans to expand the study to other age groups and people with more diverse educational backgrounds.
