Constructivists
Constructivists try to get into the right mindset for an activity and it takes time for them to get from one mindset to another. When they are at home, they are mentally prepared for anything that could happen at home and when they are at work, they switch over to work-mentality. They can get overwhelmed by emotions because once they get into an emotional state, they stay in that emotional state for a long time. Constructivists avoid emotional contact with others and they don't think it's necessary to adjust to the conversation emotionally. They use automatic polite responses and customs, like starting with "how are you?" or offering their guests coffee or tea. Practical conversation (talking "business") is easier for them. They like to repeat emotional states - rereading books, watching movies that they have already seen and revisiting places they liked. They avoid movies, situations and people who give them a negative mindset, because they have a difficult time getting rid of that mindset. Constructivists use emotional anchors (carefully chosen music, books, movies) to keep or strengthen their internal emotional state.
Emotivists
Emotivists try to enter the emotional atmosphere of the conversation and they try to keep the emotion in the conversation positive. They can talk about various things they have no interest in or do not believe in simply for the sake of maintaining a "positive spirit". Talking business is more difficult and the conversation topic can wander off into emotional exchange. They try to get new experiences and new emotions, which is why they travel to new places and rarely watch movies they have already seen. In emotivists calls for action/requests are not critically estimated and because of it they can get overwhelmed by them. After getting into a theme they stay in that mode of operation for a prolonged period of time and have difficulty switching, "disconnecting" (and because of it try to avoid unpleasant requests).
Examples
In forum conversations when a person asks a question, emotivists reply with conversational posts trying to find out what caused such a question and trying to see if they can make the person feel better. They can also include an answer to the question, but that's secondary. Constructivists give as good of an answer as they can to help find a solution. They might also include a question about why the question was asked by this particular person, but only when they are curious about it. It's not important for the thread (conversation) itself.
Constructivists don't mind seeing a movie that they have already seen, but emotivists would only do that if there might be some new information that they missed the first time or if they have forgotten a lot about the movie. Constructivists might prefer re-watching a movie that gave them a good emotion to seeing something brand new that they don't know if they'll like. This is because constructivists have inert ethics and it's difficult to get rid of the wrong emotional state, but emotivists have contact ethics so they want to experience new emotions.
