Peter (2006) argued that the balance between the positive and negative aspects of psychology would be the most telling indicator of positive psychology’s success.
In essence, the word "affect" is just a more formal method of describing feeling and expression. It speaks of the sentiments or emotions that we have and express, particularly in relation to how these feelings affect how we act and choose to do things.
Positive affectivity is the expression of positive feelings, such as joy, pride, elation, and cheer. Sadness, contempt, lethargy, dread, and discomfort are examples of negative emotions and expressions, which are referred to as negative affectivity. Our affectivity—both positive and negative—can affect our opinions, thoughts, performance, abilities, and even our brain activity in addition to having a big impact on our daily lives and happiness.
