What is Affective?
In psychology, the term affect is used to represent human affects in general, including emotion, feeling, and mood. Affects include both positive and negative status. However, the English word affection is usually used only for positive meanings such as love and gentle care.
We define the term affective as “being capable to evoke affects in people’s mind” or “being capable to deliberate affects to be evoked in people’s mind”. For example, affective products might mean “products that are capable evoke appropriate affects in users” or “products that were designed carefully considering possible affects users might have.” In the same way, the term affectiveness is used for the meanings of “how capable to evoke affect in people’s mind,” or “to what extend affects that people might have are thoroughly considered.”
