Webster's Dictionary defines "language" as "a method of human communication, either spoken or written, consisting of the use of words in a structured and conventional way." However, language does more than communication. Since we have been educated, language has been an important media of our learning, so it determines what we can know. Here comes to my knowledge question, 'to what extent does obtaining knowledge depend on language, especially in the area of human science and art?.
Psychology uses language to understand human behavior. Cognitive psychology is a branch of psychology, which studies mental processes including how people think, perceive, remember and learn skills. How people behave is depend on how they think and how they use language. So how does language affect people's behavior? In our real life, we always talk to ourselves, the psychologists call these inner voices: 'self-talk', it includes our conscious thoughts as well as our unconscious assumptions and beliefs. Most people don't realize it, but self-talk actually goes to our daily lives, as we are constantly thinking about and interpreting the situations we find ourselves in. For example, if an alcoholic continues tell himself that he needs to drink in order to have a good sleep, the internal voice inside captivated him keeping on drinking. On the other hand, self-talk can be positive if you keep telling yourself enthusiastic words. It can have a great impact on your self-esteem and confidence as you developed way of just listening what you encourage yourself each day. Using myself as an example, I will always tell myself that: "I can totally make it through this exam". This can make me feel good about myself and things that are going on in my life. Additionally, this language can be related to the people's emotion. When they are doing positive or negative self-talk, it's emotion that leads them to say the words.
