Sensation

The process of registering stimulation and transmitting that information to cortical brain centers

1

Perception

The process of assigning meaning to the sensation

2

Habituation

Is the decreasing attention to a familiar stimulus

3

Perception is really intermodal. What does that mean?

It is the result of coordination and communication among the sensory perceptual systems

4

Sensitivity to a perceptual stimulus is measured by the…

Absolute threshold

5

True or false?

Poor visual acuity in newborns is because the muscles that control the lens, the part of the eye that has to reflect light on to the retina, are weak.

True

6

True or false?

Visual acuity improves slowly over the first four months of life.

False

Visual acuity improves rapidly over the first four months of life

7

Who developed the visual cliff apparatus to determine infants and toddlers depth perception?

Gibson and Walk in 1960

8

Perceptual constancy

And important characteristic of visual perception where we can see stability shape size brightness and color of objects in our visual field

9

Size constancy

Objects we are familiar with seem to appear the same size despite changes in the distance between us and the object

10

Shape constancy

Objects appear to be the same shape despite changes in their orientation toward the viewer

11

Brightness or light in this constancy

Objects appear to stay the same brightness despite changes in the amount of light falling on them

12

Color constancy

Thank you up an object appears to stay the same despite changes in background lighting

13

Studies of color perception using the habituation paradigm report that very young infants see color and have him at your ability to perceive color by what age?

2 to 3 months of age

14

What is selective looking in infants?

Scanning the borders and edges of objects in a visual stimulus

15

True or false

True

16

True or false

False

17

Glaucoma

A buildup of pressure from excess fluid inside the eyeball

18

Presbyopia

Present in most people after the mid to late 40s, these adults have less sensitivity under dim light conditions, and have difficulty with near vision

19

The loss of hearing associated with aging is called?

Presbycusis
