The stimulation of sensory receptors and the transmission of sensory information to the central nervous system (the spinal cord and brain).

The psychological process through which we interpret sensory stimulation.

the weakest amount of a stimulus that can be sensed.

The minimum amount of difference that can be detected between two stimuli.

The process by which we become more sensitive to weak stimuli and less sensitive to unchanging stimuli.

Signal-detection theory

A method of distinguishing sensory stimuli that takes into account not only the stimuli's strengths but also such variable elements as the setting, your physical state, your mood and your attitudes.

The opening in the colored part of the eye.

Adjusts to the distance of objects by changing its thickness

The sensitive surface in the eye that acts like the film in a camera.

Neurons that are sensitive to light.

The point of entry of the optic nerve on the retina, insensitive to light.

The colors across from each other on a color wheel.

The visual impression that remains after the original image is removed.

A bony tube that contains fluids as well as neurons that move in response to the vibrations of the fluids.

Projects auditory input onto the hearing areas of the cerebral cortex.

Occurs because of damage to the middle ear.

Caused by damage to the inner ear.

The receptors send information about the odors to the brain via the olfactory nerve.

Suggests that only a certain amount of information can be processed by the nervous system at the time.

Tells whether you are physically upright without having to use your eyes.

The sense that informs people about the position and motion of their bodies.

The tendency to perceive a complete or whole figure even when there are gaps in what your senses tell you.

Nearness of some of the lines to each other.

The unbroken and consistent existence or operation of something over a period of time.
