Top-Down Processing

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

State

Top-down processing uses existing knowledge and expectation to interpret incoming sensory data.

Show

A misspelled word in a familiar sentence is read as correct without the error registering.

Watch for

Top-down processing is not error. It is what makes reading fast, and the same mechanism produces the mistake.
