Midterm 2 Short Answer Questions - Chapter 8 Flashcards
How does color perception influence object and face recognition? What challenges are posed by color deficiencies like achromatopsia?
Color perception aids in object and face recognition by providing visual cues. Color deficiencies like achromatopsia challenge color-based recognition due to impaired color discrimination.
Describe Newton’s prism experiment and its contributions to understanding color perception.
Newton’s prism experiment demonstrated the visible spectrum by splitting white light, contributing to our understanding of color perception and the nature of light.
Explain the opponent-process theory of color vision and its proposed color pairs.
The opponent-process theory suggests opposing color pairs (e.g., red/green, blue/yellow) in visual processing, explaining color perception and afterimages.
Discuss the role of the fusiform face area (FFA) in face perception and recognition. How is it specialized?
The fusiform face area (FFA) specializes in face processing, showing increased activity during facial feature analysis and familiar face recognition.
What are some functions of color perception beyond object recognition, such as conveying emotional cues?
Color perception conveys emotional cues (e.g., red for anger), aiding in perceptual organization, and contributing to aesthetic experiences.
Define tonotopic maps in the context of auditory perception. How do they relate to frequency representation?
Tonotopic maps represent frequencies orderly along a structure (like the basilar membrane), crucial in auditory processing for frequency analysis.
Explain Békésy’s Place Theory of Hearing and how it explains our perception of different sound frequencies.
Békésy’s Place Theory correlates a sound’s frequency with the place along the basilar membrane that activates, explaining how we perceive different sound frequencies.
What are resolved and unresolved harmonics in the perception of sound, and how do they contribute to pitch perception?
Resolved harmonics have distinct peaks in frequency analysis, while unresolved harmonics lack clear peaks, both contributing to pitch perception.
Describe the tonal arrangement along the basilar membrane and its role in auditory processing.
The basilar membrane’s tonal arrangement corresponds to different frequencies, activating specific regions in response to varying sound frequencies.
How do cochlear implants function, and what components are involved in these devices?
Cochlear implants electrically stimulate auditory nerve fibers, consisting of components like a microphone, sound processor, transmitter, and receiver for hearing restoration in deaf or hard-of-hearing individuals.
