Is Style in Short Fiction Different from Style in Long Fiction?

Is style in short fiction different from style in long fiction? More specifically: are short stories different stylistically from novels (even if we talk only of some types of short stories, vs some types of novels; and differing in degree rather than in kind)? In the context of a symposium on Style in Fiction, this essay makes some points about style in short fiction, and a particular respect in which it may differ from style in novels. I begin with some observations about some domains where it is hard to see a short story/novel stylistic contrast; I then make some points about what are widely accepted as features characteristic of stories; thereafter I focus on the occurrence in some stories (but not, I hypothesize, in novels) of what I call High Emotional Involvement Passages, which are distinct in form and function from ambient story text.
