The smallest intensity of a stimulis that must be present for it to be detected.
What is absolute threshold
100
An adjustment in sensory capacity after exposure to unchanging stimuli
What is adaptation
100
These cover the basilar membrane and, when bent by vibrations entering the cochlea, transmit neural messages to the brain.
What are hair cells

This theory suggests that there are three kinds of cones in the retina, each of which responds primarily to a specific range of wavelengths.
What is the trichromatic theory of color vision
500
This theory states that when certain skin receptors are activated as a result of an injury, a "pathway" to the brain is opened, allowing pain to be experienced.

When elements that are close together are grouped together it is known as this.
