1. Seems like William James’ somatic theories, which suggested that bodily reaction comes first and affects the emotion human expresses, was dominating in emotion study area before cognitive theories were developed in the 1880s. The James-Lange theory had until 1953 been all abandoned by most scholars. But later there was a neo-Jamesian theory appeared which was based on James’ theories.
2. I read Bruce Hull’s articles a second time after i found some info about the relationship between emotion and mood. Got two more issues:
a. There’s a clear distinction between mood and emotion (non-object and object, long-last and short time, incapable to be expressed and capable to be expressed), but i can’t find a formal citation for this important part.
b. In Bruce’s two articles, Explaining the Emotion People Experience in Suburban Parks and Mood as a Product of Leisure: Causes and Consequences, seems like he thought mood was equal to emotion, and use the PAD coordinate to describe both mood and emotion. While in Wikipedia, it was said that the PAD emotional state model … uses three numerical directions to represent all emotions.[Citations here] ( http://en.wikipedia.org/wiki/PAD_emotional_state_model )
