Sensation and Perception Quiz

Sensation and Perception: Understanding the Human Senses

• Oliver Sacks, a physician and author, has prosopagnosia, a neurological disorder that impairs facial recognition.
• Sensation is the bottom-up process of receiving stimuli, while perception is the top-down organization and interpretation of that information.
• The Absolute Threshold of Sensation is the minimum stimulation needed to register a stimulus 50% of the time.
• Signal Detection Theory predicts how and when a person will detect a weak stimulus based on their psychological state.
• Sensory adaptation is the process by which the senses adjust to constant stimulation.
• Difference Threshold is the point at which one can tell the difference between two stimuli, and Weber's Law explains that we perceive differences on a logarithmic scale.
• Vision involves light waves that are transformed into neural messages by the retina's rods and cones.
• Rods detect grayscale and are used in peripheral vision, while cones detect fine detail and color in well-lit conditions.
• The Young-Helmholtz trichromatic theory suggests that the retina houses three color receptor cones that register red, green, and blue.
• The opponent-process theory suggests that we see color through processes that work against each other.
• The brain's visual cortex processes input from the eyes and has feature detectors that respond to specific features like shapes, angles, and movements.
• Parallel processing allows the brain to simultaneously process and analyze many separate aspects of a situation.
