this is a quick video explaining emotion in the context of social psychology the information is from my summary of the scientific course from Macquarie University firstly what is emotions emotions are brief specific psycho psychological responses that drive goals which need to be met and they are usually social goals mood are more enduring than emotions and have less specific causes the duccini smile was discovered by Ekman and it is a genuine smile in which the crow's feet by the eyes can be seen even more the universality of basic expressions can be illustrated through the fact that 90% of isolated people 90% of people who live in isolated communities around the world could identify happy faces but other expressions less so in the physiological responses of emotions we assume that we first feel the emotions and that causes a bodily reaction causes us to react here's a layout of the emotional reaction which first it stems from perception then there is an emotion and then as a result the emotion causes us to act out in a physiological response emotions affect the autonomic sympathetic and parasympathetic nervous system the sympathetic nervous system controls fight and flight and the parasympathetic controls rest as I've stated earlier in another video James Lang's fury of emotions according to this theory emotions happen after visceral arousal and motor reaction this is a counterintuitive model because it states that emotions occur at the end peripheral theories include how autonomic system is activated before the central nervous system is able to interpret what is going on canons criticism of James the central nervous system is important because it causes hypothalamic arousal which creates bodily changes and emotion simultaneously reasons for this criticism include how previous expect showed in the spinal lesions of animals that animals continue to display emotions despite well having a spinal lesion James Lange's model doesn't differentiate between the different emotions despite it occurring from the same physiological responses from the same physiological arousal so instead Canon postulates in this hypothalamic arousal that then causes both bodily experiences and emotions facial feedback late nineteen eighty-four by placing electrodes on the face and asking participants to lift up a cheek Laird was able to force people to smile and this made them happier this does shows that there is a facial feedback loop in which emotions are influenced by facial expressions which are also influenced by emotions SCADA and singer 1962 postulated the two-factor theory model in which emotions experienced by one depends on the situation's meaning or the attributed arousal in the experiment individuals a place in an adrenaline or placebo group and some of the participants in the group are informed of the true effects of adrenaline and thus over attribute to adrenaline and others who were not informed of the effects of adrenaline did not over attribute to the adrenaline and thus felt more like the Confederates this thus found that undifferentiated arousal occurred first and then a construe was developed later post hoc reasoning in which one reasons for the cause of the arousal why has taken place Zil man in 1978 discovered the miss attribution of arousal in which he showed participants cartoons or erotic pictures and they made a misattribution of arousal since before they were shown these images they were told or required to ride a bike and yeah they made a mess attribution of arousal in summary we briefly looked at the physiology of emotions by defining key terms like mood touch any smile and we also looked at theories like the common physiological response Theory james-lange theory of emotion cannons criticism Laird's facial feedback SCADA and singer 1962's two-factor theory model and zil man's misattribution of arousal the next video I will be talking about discussed thanks for watching
