An automatic attentional response to a novel or unexpected stimulus, involving a shift of focus toward the source.
From Latin 'orientem' meaning 'the rising sun, the east,' from 'oriri' (to rise). Sense of turning toward something.
The orienting response is your brain's 'What was that?!' reflex — a sudden noise makes you turn your head before you even think about it.
