Noun
affectivity (countable and uncountable, plural affectivities)
Ability to experience affects: feelings, emotions, judgement, motivations, etc.
At the same time, the kinds of affectivities evoked in us, such as fear and gratitude, also depend partly on how we envision and interpret the objects in question.
I think you can be depressed and flourish, I think you can have cancer and flourish, I think you can be divorced and flourish. When we believed that happiness was only smiling and good mood, that wasn't very good for people like me, people in the lower half of positive affectivity. Martin Seligman
