PSYA01H3 Chapter Notes - Chapter 4: Absolute Threshold, Neural Adaptation, Sound
Document Summary
Basic registration of light, sound, pressure, odor, or taste as parts of your body interact with the physical world. After sensation registers in your central nervous system, perception takes place at the level of your brain. The organisation, identification, and interpretation of the sensation in order to form a mental representation. Occurs when many sensors in the body convert signals from the environment into encoded nerve signals sent to the central nervous system. Methods that measure the strength of the stimulus and the observer sensitivity to. The response to a stimulus depends both on a person"s sensitivity to the stimulus in the presence of noise and on a person"s decision criterion. Sensitivity to prolonged stimulation tends to decline over time as an organism adapts to current conditions. Light waves have three properties: link, amplitude, and purity the ability to see fine detail. What human see from these properties are color, brightness, and saturation. Length - what we perceive as color.
