Study Notes
Visual Perception and Processing
- Opponent process theory explains the perception of colors and afterimages when contrasting colors are viewed, such as seeing red, white, and blue after green, black, and orange.
- The blind spot in the eye occurs where the optic nerve exits; this area lacks photoreceptors and contributes to blind spots in vision.
- Visual problems are often linked to difficulties in the visual cortex, where visual information is processed.
Anatomy of the Eye and Hearing
- Balance is facilitated by receptors located in the inner ear, which play a crucial role in maintaining equilibrium.
- Sound waves first contact the eardrum as they travel through the auditory canal; this is crucial for sound transmission.
- The perception of pitch in sound waves is determined by their frequency; higher frequencies correspond to higher pitches.
Theories of Pain and Color Vision
- Gate control theory explains why rubbing an injured area can ease pain; it suggests that the spinal cord contains a gate that can block pain signals.
- Color blindness often relates to the functionality of cones, the photoreceptors responsible for color detection in the retina.
Auditory and Visual Cues
- Top-down processing allows individuals to interpret ambiguous sounds, like backward music, based on expectations, suggesting prior knowledge influences perception.
- Bipolar cells in the retina relay visual information to ganglion cells, which collectively form the optic nerve responsible for transmitting visual data to the brain.
- Depth perception can be compromised when one eye is occluded, making tasks like climbing stairs more challenging due to the loss of binocular vision cues.
Sensory Processing and Adaptation
- In low light, peripheral vision prevails as rods in the retina become more active than cones, aiding visibility in dim conditions.
- Accommodation is the eye's ability to change the lens curvature to focus clearly on objects at varying distances, a crucial function for clear vision.
- The semicircular canals are vital for balance, sensing rotational movements and assisting in spatial orientation.
Brain Function and Sensation
- The frontal lobes of the brain receive signals from hair-like receptors involved in the vestibular sense, crucial for balance and spatial orientation.
- Afterimages support the opponent-process theory, demonstrating how color perception can be altered based on previous exposure to contrasting colors.
