Understanding Core Concepts in Psychology: Monoism, Dualism, Perception, and Sound Localization

This midterm review covers fundamental psychological concepts including the distinctions between monoism and dualism, the structure of neurons, and the differences between sensation and perception. It explains the nature of sound perception, detailing how we recognize tones of various frequencies and their loudness. Additionally, it discusses key cues for sound localization and the concepts of pure tones and acoustic-phonetic invariance. The review also contrasts categorical perception and cross-modal integration, enhancing comprehension of sensory processing.

  4. Question 3 What is sensation? What is perception? Sensation is acquiring information about the outside world Perception is interpreting information about the outside world

  5. Question 4 Imagine a sound wave that causes high magnitude of displacement at the apex end of the basilar membrane. How would you perceive this sound? A loud, low pitched tone

  6. Question 5 A 100 Hz test-tone played at 50 dB would have a SPL of ___ dB 60

  7. Question 6 After listening to a 5000 Hz tone you would expect to experience hearing loss for _______ after exposure 4days

  8. Question 7 What are four cues you could use for localizing sound? Arrival time Phase lag Head related transfer function Room Echoes

  9. Question 8 What is a pure tone? Sounds with only one frequency

  10. Question 9 What is Acoustic-phonetic invariance? Phonemes should match one and only one pattern in the spectrograms Is it true? NO!

  11. Question 10 What is the difference between categorical perception and cross-modal integration? Cross-modal integration is the integration of two or more different sensory inputs Categorical perception is a phenomenon in which the brain assigns a stimulus into one or another category but never into an intermediate category
