What is the difference between a jump scare and slow dread in horror, and what has actually been measured about each?
A jump scare is a sudden image plus a loud sound (a startle); dread is sustained anticipation before a threat arrives. Open sources support a two-part structure: a measurable anticipation phase that raises later reaction, and an acute reaction at the scare. The strongest measured evidence is one fMRI study of feature-length horror films with self-rated fear; the jump-scare-specific physiology is described by its own authors as not yet studied.
