What is the relationship between working memory and positive or negative mood as higher order affective states which can change vary slowly compared to moment-to-moment affective responses (both valence and arousal)? Are there any literature related to this?
Welcome to the community Dalek! Emotional states can guide the actions and decisions we make in our everyday life through their influence on cognitive processes such as working memory. I would like to share with you couple of sources (Figueira et al., 2017 and Baddeley, 2012) which can be quite helpful for you.
People over here tried to figure out emperically how our moods are affecting cognition processes.
