How can a person's words, on a physical, mechanical level, effect another person's emotional status?

Question

And, if it is due to the soundwaves(or whatever sensation) exciting a neurological stimulus, how would you account for the neurological states being resultant of an arbitrary stimulus, i.e. the physical properties of a language's sound waves are different. Thus neurologically speaking, the stimulus associated with the word "love" in the sound based neurosystem isn't the same across the spectrum of languages. Keep in mind that i'm talking about soundwaves, not brain-states.

What i'm saying is that though the stimulus is different, the result is the same. Further, what i'm trying to suggest is that emotion is arbitrary based on that fact, such that you're emotional state is your choice. There may be physical states related to love, but that doesn't have much to do with what i'm trying to say here, which is that the initial stimulus for that emotion is arbitrary; "Love" does not exist, it's just a soundwave. So, How can a person's words effect emotional status?

Answer 1

Tell me how you feel? You are a stupid person! Your so stupid you tried to kill a bird by throwing it off a mountain cliff! So tell me, how did you feel?

Answer 2

You learn the language. You learn what the words mean. They have meaning. Each and every word we learn has it's own meaning. The word, "love" has a meaning that is related to a deep emotional feeling and being. Therefore, if one learns that word, and its proper meaning, and if perhaps, they have experienced emotional love in their own life, then it would stand to reason that they would have an emotional response to the word. Same thing with any word that is tied into some kind of feeling or emotion, such as the word, "hatred", or "shame", or "happy", "serenity", "murdered", and so on. Or, if one is in a serious relationship, lets say, one that is having some serious problems, and lets say the person listens to these words: "cheating", "lying", "betrayal", etc. I would think that the person would have a rather noticable emotional response to these particular words, wouldn't you think so? Well, that is my opinion.
Good question by the way.

Oh, one more thing, if you hear these words in another language, but you do not understand any words of the language that you are listening to, I don't believe there would be much of an emotional response to any particular word. Perhaps?
