Literature review and research questions
There are a number of terms like mood, emotion, affect
describing similar ideas. We want to first define what
we mean by mood and differentiate it from the other
similar terms. Mood is a transient and diffuse affective
state. It does not tie with any explicit causes and
usually runs in the background of our daily life. Emotion
is different from mood and is a stronger affective state
compared to mood. It has the specific salient causes
and operates in the forefront of our life. [4] However,
mood and emotion are associated. Emotion can
degrade into mood. Mood can also moderate the
threshold of emotion. [4] Affect is another similar
concept. Affect sometimes is used as a synonym for
emotion. It can also refer to the positive or negative
aspect of feelings. Affect is a broader concept than
emotion. [11] In our study, we use mood to refer to
the most common affective state operating in the
background of our daily activities. Affect is employed to
refer to the positive or negative aspect of the mood,
such as positive mood, happy, pleasant, content,
negative mood, sad, unhappy, unpleasant, or upset
