The Role of Biological Processes in Perceiving Emotion: Physical Makers of Emotion (Signatures of Emotion) – Emotion (PSY, BIO)

00:02 Now, let's talk about some of those physiological makers that we talked about in terms of emotion.

00:08 And we kind of keep bringing them up.

00:10 And they keep coming up and they will continue to come up.

00:14 We are going to walk through some of those.

00:16 So heart rate, blood pressure.

00:18 Your breathing rate.

00:19 How are you breathing when you are nervous, you might have short shallow breath when you are calm and when you are asked to remain calm, what do they always say, is say to you, You are about to get late for your exam, relax.

00:29 Take a couple of deep breaths.

00:32 So that breathing actually will change your emotional state.

00:37 Sweating, you can't necessarily control.

00:40 And the level of stress hormones, again these are things that you can control but they were directly impact your emotion.

00:46 Now all of those are linked to your sympathetic nervous system or the SNS.

00:50 And there is an overlap of some of these characteristics which we've already highlighted related to emotion.

00:56 So when I said fear versus anxiety, versus sexual arousal, you might see some commonalities between some of these -- some of these physiological characteristics even though the resultant emotion is completely different.

01:09 Okay, so let's summarize everything we just figured out here.

01:12 So, I want you to remember the fact that there's three main components.

01:16 Physiological, behavioral and cognitive.

01:19 These three individual components, collectively will shape the emotion that you express.

01:24 I want you to be familiar with the three different theories or models behind how we express our emotion.

01:30 And ultimately I want you to be very familiar with the two different types of nervous systems are important, the sympathetic and parasympathetic.

01:37 The fight or flight or the rest and digest.

01:40 Both different yet related.

01:42 Both fall under the autonomic number system.

01:44 But each plays a different role.

01:46 And how we express our emotion.
