What do people think when they meet you? Why do you instantly like -- or dislike -- someone? People are hardwired to size one another up, processing thousands of units of nonverbal data in the time it takes to snap one's fingers. Premier body language expert Patti Wood here distills the science on how we form SNAP impressions into information everyone can use everyday -- on job interviews and sales calls, while meeting in person or on Match.com, during telephone calls or Skype communications. With the warmth and humor that have made her an in-demand media, business world, political, and law enforcement consultant and coach, Wood provides practical tips and tools on everything from handshakes, eye contact, and body language to deception detection, dating, and technological communications. Readers learn to boost their credibility, likeability, attractiveness, and power so that they can always make their best possible first impression -- and form savvy SNAPS of others.
