Richard Gregory introduced the concept of top-down processing in 1970. A phonics approach to teaching reading supports bottom-up processes.

Phonics is a method to facilitate students access to text to ultimately lead to comprehension. Top-down processing is the idea that to process and understand a text we start with higher-level features background knowledge context overall meaning and proceed through a series of steps down to lower-level semantic syntactical and phonological features.

How might bottom-up and top-down processing be involved in our perception of a illusory contours and b ambiguous figures.
