The Emotions we feel, be it happiness, sadness, anger, love etc a result of the culture we are in? Yes. Though there are certain emotions which are innate or inborn and are universal for all.
The culture we live in not only influence how we display emotions we feel, but, also influence our facial expressions, our understanding of it, their restrain and their creation. For example, the Japanese feel more angry when strangers are involved, whereas for an American, relationships are an antecedent to anger.
It was a study by Ekman and Friesen in the year 1972 studied the expressions of Americans and Japanese to highly stressful films. This study was very important to understand the phenomena of ‘Are Emotions Culturally Shaped?” Though there are various evidence to prove this, some researchers do not believe in this.
