Things To Consider We can perceive objects. What are (some of) the theories of object perception? Are the descriptive or prescriptive ? Does any one of them cover everything? Are they mutually exclusive? We can also perceive objects in motion. How does the process differ from perceiving a stationary object? What does it mean to propose that face perception is a domain specific capacity? 2

The Sensation Process Sensation: detection of a stimulus in the environment, by a sensory organ Sensory system: system that receives and processes sensory stimuli from the environment Sensation Sensation is biochemical and neurological. Sugar example: Chemicals in sugar excite nerves in tongue. Sensation is psychologically low-level. (“Low-level” is not an indicator of importance.) Sensation is relatively less complex than other cognitive functions. It is shared with other animals. 4

Computational Approach to Perception Computational approaches suggest that we use cues directly from stimuli to interpret the environment. Bottom-up processing: Understanding the environment through feature identification and processing Processing based on the stimulus Two examples of bottom-up processing Grass: recognition based on features we can see and compare to memory representations Written letters Features of letters: visible, analyzable lines and curves We match features of the stimulus to patterns of features stored in memory. 1 0

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
