快樂的人說話更吸引別人

        The EAR sampled 30 seconds of sounds every 12.5 minutes yielding a total of more than 20,000 recordings. Researchers then listened to the recordings and identified the conversations as trivial small talk or substantive discussions. In addition, the volunteers completed personality and well-being assessments.
