Study Notes
Sensory Processing
- Top-down processing uses previous knowledge to interpret sensory stimuli.
Chapter 2 Focus
- Chapter 2 focuses on the interplay between bottom-up and top-down processing in perception.
Bottom-Up vs. Top-Down Processing
- Bottom-up processing is data-driven; it starts with sensory input and builds up to perception.
- Top-down processing is conceptually-driven; it uses prior knowledge and expectations to interpret sensory input.
Overactive Top-Down Processing Example
- An example of overactive top-down processing is misinterpreting a blurry image based on pre-existing expectations, rather than relying on the raw sensory data.
Neuroscience Research Focus
- Neuroscience research in the text focuses on how the brain integrates sensory information using both bottom-up and top-down processing mechanisms.

Description
Test your knowledge on perceptual processes related to visual and auditory recognition. Explore the background on visual object recognition, theories of visual object recognition, and the distinction between bottom-up and top-down processing. Challenge yourself on topics like the organization of the visual system and the role of top-down processing in reading.
