Bottom-Up Processing

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Bottom-up processing builds a perception from the incoming sensory data upward, without prior expectation.

Show

Reading an unfamiliar word letter by letter, with no guess available in advance.

Watch for

Pure bottom-up processing is rare in adults. It appears most clearly with genuinely novel stimuli.
