If you’re wondering how someone is feeling, a smile or a scowl may give you a lot of information. Facial expressions are often the most obvious sign that someone is feeling happy, sad, or angry. But you may not realize how much information you are getting from other types of cues, like the environment, the context, or the words you are seeing or hearing. Because words allow us to generalize and label things, they may affect how we perceive and categorize other things that we see.
