- [Voiceover] So let's talk about a topic important to song writers everywhere. Emotions. Emotions are felt by everyone but how they are expressed and experienced is very different depending on the individual which makes them complicated to understand. But simply put in psychology, we understand emotions to be subjective experiences that accompany vibe physiological, behavioral, and cognitive changes and reactions. So let me explain each of these in a bit more detail. First, let's look at the physiological components of an emotional experience. Every emotion produces different physiological responses within the body which can include distinct changes and patterns of brain activation, neurotransmitter production and autonomic nervous system activity. For example, let's use you as an example here. Let's you're standing here minding your own business in a room and then all of a sudden, surprise! Everyone jumps out and surprises you because it happens to be your birthday. So you, the individual here, might have a distinct physiological reaction. Your heart rate may increase as a result of being startled, your muscles may be temporarily tensed and then relaxed, and your skin temperature may increase as well. Now, at the same time, your cognitive process is going on as well but are very different person to person and culture to culture. So cognitive reactions are mental of assessments that can include appraisals and what is happening, expectations about the situation and general thoughts about the experience. So in this example for the surprise party, someone who has been to a surprise party before may have the expectation that it'll be fun or they might be thinking about the people who are there or maybe they're just saying, "Oh, my God," because they are so surprised. This is an example of a cognitive experience happening as a result of emotions. These cognitive experiences can also bring in bad emotions. So for instance if you happen to think about how you dislike parties, now, I don't know why that would be, but if you really don't like parties for some reason, you might feel like dread at the prospect of a surprise party instead of joy. And that emotion was brought on by your cognitive experience. And lastly, each emotion produces different behavioral responses which can be evident in body language or facial expression. So in our surprise example, an individual may smile, clap their hands in delight or open their arms or hug their friends and relatives. Again, these expressions vary by individual and can be interpreted differently culture to culture. So let's return to our chart here and review the basics. Emotions are made up of cognitive, behavioral, and physiological changes that are all interrelated. But what else do we know about emotion? Well, first, emotions are temporary. They have relatively clear beginnings and relatively short durations unlike moods which can last much longer and are not necessarily discreet. Secondly, emotions can be negative or positive. So as an example, someone can be happy, sad, angry or delighted. Along the same lines, emotions can vary in intensity. So a person can experience a little bit of sadness or a deep feeling of depression. They can be extremely ecstatic or just a little pleased. And lastly, emotions, generally, are involuntary. It means that you can't decide what you will experience which is why we use these phrases such as someone falls in love or explodes with rage or is overwhelmed with excitement. These expressions kinda illustrate how emotions are involuntary. So with all that mind, here's a question for you. How many emotions are there? Well, the answer is there's probably an infinite number. But a researcher named Paul Ekman found that there are special set of six emotions that could be easily identified by individuals all around the world and these are known as the universal emotions. And these universal emotions are happiness, sadness, fear, disgust, anger, and surprise. And you might be wondering why are they called universal emotions. Now, they aren't called universal emotions because everyone feels them the same way. They're called universal emotions because they have consistent facial expressions across cultures. And so, they're easily recognizable no matter what cultural background you come from. So here's an example of the six universal emotions. I'm gonna give you a few seconds here to look at it, maybe pause this video and see if you can guess what each of these six represent. I'm gonna go through each of these expressions here and show how they relate to the emotion, how they represent. Now, I get kind of kick out of this because I'm gonna explain emotions that we all experience every day and I'm gonna explain it in a very clinical cold sounding manner. But I think it's kinda interesting to kinda break it down like this. So here's happiness. And it's representing happiness because of the raised cheeks. You can see elevated corners of the mouth. Sometimes teeth are exposed. Sometimes wrinkles on the outward corners of the eyes. So that's happiness. And here we have sadness. Sadness is represented by an uplifted inner corner of the eyebrows, some downturn lips. And here's fear. Fear's represented by eyebrows being raised and drawn together, wrinkles in the middle of the forehead, eyes are open in tense, mouth is open, lips are drawn back tightly. So that's fear. And now, we have anger. Anger's represented by like this penetrating stare that they have here. Your eyelids are tensed, your lips are pressed together. So that's anger. And here's disgust. Disgust is represented by raised cheeks, wrinkled nose, your brows are lowered. And with surprise, just like we saw on that little cartoon we drew earlier, surprise has raised eyebrows, eyes are opened wide, the jaw is dropped so they have an open mouth. So that's surprise. And here's another question to consider. Why would these emotions be universally recognizable? Well, the answer comes to us from Charles Darwin. You probably know of Darwin and his studies in evolution. Well, Darwin hypothesized that the ability to express and understand emotion is an innate ability and it helped individuals to act in ways that gave them a better chance of survival. So emotions actually have an adaptive value. And this makes a lot of sense. Think about a newborn baby. If they're surprised or frightened, they often react in ways that are very similar to how grown ups act. But newborn babies are brand new to the world. They've never been taught how to do these things. Their bodies just react that way. And what's really interesting is that individuals who have been blind their entire lives and have never been able to see of what a human face looks like, they also have similar facial expressions to people who can see even though they have never seen a smile or a frown. And this also supports the idea that the expression of some emotions are innate. So when it comes to emotions, think of the three components, the cognitive, the physiological, and the behavioral. And remember that universal emotions exist.
