Stimuli | An object or event that triggers a sensory or behaviour response. |
Sensory Receptors | A structure that reacts to physical stimulus in the environment |
Receptive Field | Is a particular region of the sensory space. |
Transduction | Is what takes place when many sensors in the body convert physical signals from the environment into nural signals for the brain. |
Transmission | Is how the nervous system transmit information across a synaptic gap |
Cornea | The Transparent Layer forming over the front of the eye |
Pupil | Is the Circular opening in the center of the iris which allows light to pass through the lens of the eye. |
Iris | A thin circular structure in the eye responsible for controlling the diameter and size of the pupil. |
Ciliary Muscles | Is responsible for moving the lens for distance vision by expanding and controlling |
Lens | Behind the pupil and is enclosed in a thin transparent capsule |
Retina | A layer of light sensitive tissue located at the back of the eye. Images a focused at the back of the retina |
Photoreceptors | Are light sensitive cells that are find at the retina |
Rods | Allow black and white images, provides perhiphal vision and there are about 125 million rods |
Cones | Provide color vision, provides central vision and there is 6.5 million |
Fovea/Macula | Is a concentrated area of cone respecter on the retina |
Optic Nerve | Carries visual messages to the brain |
Blindspot | Is where the optic nerve leaves the eye |

Linear Perceptive | Is a depth cue that is realted to size and the other cues. |
Interposition | Is a signal that tells you that a object is closer then another object by perceiving the image taking up most of the further image. |
Texture Gradient | Is when we can see by using one eye and not having to depend on both eyes. |
Relative size | Is a perceptual cue which shows us how close the object is to known size. |
Brightness Constancy | For visual objects to have the same brightness. |
Size Constancy | Is perceiving an object as being the same size even if it is further or closer. |
