It seems to me that this relationship is foregrounded in for example Japanese arts, but that the two are often uncoupled , for example in arts in the UK? I'm not restricting my field to the arts, and all other perspectives are welcome.
Imagination is based on mind while emotion is related to feeling. The process happening in two different ways. We use our mind to think first, relate ideas with memories to form imagination. In the other hand, emotion is reaction towards events or thing that happen around us will touch feeling and execute actions.
I feel imagination is linked to emotion in the way of themes. The specifics of an imagined situation often carries with it a certain emotional content, based on personal experience or conditioned belief related to the scenario that takes place in imagination. This also is true in the reverse. When feeling a certain emotion, say fear, courage, excitement, love, ecstacy, the imagination often goes rampant to generate a landscape corresponding to those emotions. For me, peace is linked with hiking in the Norwegian mountains. I wonder and assume that this differs per person.
How do your positions respond to Vygotsky 's linking of the emotions to thought, through which h gave aesthetics a new role in the process of consciousness? My specialism is in learning through arts-based research, particularly drama and theatre forms. Through this i have had the pleasure of working with colleagues in many different fields including science, engineering and business. In my work the 'emotional reality of imagination' which Vygotsky talks about is a central assumption. I know that this is not an original thought at all (Lindqvist, G. Creativity Research Journal, 2003, Vol. 15, Nos. 2 & 3, 245–251), but just wondered how you-or any one else- sees this today.
