Term
|
Definition

|
Term
|
Definition
| the activation (often unconsciously) of certain associations, thus predisposing one;s perception, memory, or response |

Definition
| process by which the eye's lens change shape to focus near of far objects on the retina |
|
|
Term
|
Definition
| light sensitive inner surface of the eye, containing receptor rods and cones plus layers of neurons that begin the processing of visual info |
|
|
Term
|
Definition
| retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision when cones don't respond |
|
|
Term
|
Definition
| retinal receptors concentrated near the center of the retina; that function in daylight or well-lit conditions; detect fine detail and give rise to color sensation |
|
|
Term
|
Definition
| the central focal point in the retina, around which the eye's cones cluster |
|
|
Term
|
Definition
| point at which the optic nerve leaves the eye, creating a "blind spot" b/c no receptor cells are located there |
