Document Summary
Sensation: how sense organs respond to external stimuli and transmit the responses to the brain. Perception: the processing of sensory signals that result in an internal representation of the stimulus. Transduction: a process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation. Absolute threshold: the minimum intensity of stimulation that must occur before we can experience a sensation. Difference threshold: the minimum amount of change required in order to detect a difference between intensities of stimuli. Sensory adaptation: when an observer"s sensitivity to stimuli decreases over time. Taste buds: sensory receptors that lets you taste. Olfactory bulb: the brain centre for smell, located below the frontal lobes. Pheromones: chemicals released by animals that trigger physiological or behavioural reactions in other animals. Sound wave: the pattern of changes in air pressure through time, results in sound. Eardrum: a thin membrane which sound waves vibrate. Ossicles: 3 tiny bones; the malleus (hammer), incus (anvil), and stapes (stirrup).
