I'm interested in learning more about the central nervous system (CNS) arousal and the choice of what people do and how they feel about it.
Lets define CNS arousal in the context of this question as the measure of gross motor activity measured by an actigraph in a given hour. A person with high arousal would display more intense and more frequent pattern of activity (any motion), while a person with less CNS arousal would exhibit smaller and less frequent motions.
Is there any correlation between the gross sum of body movement and choice of activity? Are people experiencing high CNS arousal more likely to engage in activities?
A related question is - if they are related, how are choice of activity and arousal give rise to each other? Does arousal cause choice of activity or does choice of activity influence CNS arousal?
