4.4 Top Down and Bottom Up Processing

Flashcards covering key concepts of top down and bottom up processing as discussed in the lecture.

What is top down processing?

Top down processing is when we use our previous knowledge, prior experiences, and expectations to guide our perception.

Give an example of top down processing.

An example of top down processing is interpreting an ambiguous letter as a 'b' if you are primed to think about letters, or interpreting it as '13' if you expect numbers.

What characterizes bottom up processing?

Bottom up processing is when we build our perception from individual features without prior expectations or knowledge.

What happens when you encounter unfamiliar signs in a new country?

You rely on bottom up processing, analyzing each sign's features to derive meaning without any prior expectations.

How can expectations affect perception?

Expectations can guide perception, making it easier to discern details or interpret ambiguous images when prior information is provided.

What happens to perception when given additional information before observing an image?

Providing additional information can shift perception from bottom up to top down processing, allowing for clearer understanding of the depicted elements.

What is a real-world example of top down processing while driving?

In a familiar environment, you quickly decipher road signs using top down processing based on your knowledge of what they usually mean.

How does bottom up processing work when viewing a new drawing?

In bottom up processing, you start analyzing individual features of an unfamiliar drawing to form a complete perception.
