Moderator：Hello, ladies and gentlemen. It gives me great pleasure to introduce our speaker for today’s lecture, Dr. Mike Donald. Dr. Donald, professor of sociology at Washington University, has written numerous articles and books on the issues about interpersonal relationships, which tend to be a key factor to success in the modern society.
       Dr. Donald：Thank you for that introduction. I feel happy to meet you here. From the moment you meet someone for the first time, you quickly want to assess who the person is and what they represent. This is why you may be on the lookout for certain stable qualities like honesty, kindness and intelligence. Paying attention to these things may even help you evaluate if you will want to pursue an intimate relationship with this person or not. Such judgment of character could be helpful on major decisions such as pursuing a romantic relationship, employing an individual or accepting a job offer. Based on these things, this is how people judge your personality and determine who you are and who you might not be. According to a study, the way someone writes and the size of their handwriting can tell you certain things about the person. According to the research which was conducted by the National Pen Company, it is revealed that persons with small handwriting tend to be shy, meticulous (一丝不苟的) and studious while people who were more outgoing tried gaining attention with larger handwriting. Those who take things seriously put more pressure on the pen when they write, while light-handed writers typically tend to be empathetic and more sensitive. According to an article on Psychology Today, the color you frequently turn to for clothes or are more akin to says a lot about who you are. People who frequently choose black are sensitive, artistic and attentive to details, while those who love red live life to the fullest and are proactive in their endeavors. People who love green are loyal and affectionate, while those who love white are organized and logical, and those who have blue as their favorite color are stable, sensitive and considerate of others. Certain body-focused repetitive behaviors can say a lot about your personality. How your body reacts to situations, whether by pulling your hair, biting your nails or picking at your skin could elicit impatience, frustration, boredom and dissatisfaction. Take nail biting for example. Those who bite their nails tend to be perfectionists, while also tense and often nervous. According to psychologists, you can correctly judge a person just by looking at their shoes. According to the lead researcher Omri Gillath from the University of Kansas, just by examining the cost, style, color and condition of the shoes, you can be able to guess about 90% of the owner’s personal characteristic such as his or her income, political affiliation, gender, and even age. Hope you enjoy today’s lecture. Thank you!
