Question 1

absolute threshold

Answer 1

is the smallest level of stimulus that can be detected, usually defined as at least half the time.

Question 2

young Helmholtz trichromatic theory

Answer 2

within your eye are tiny cells that can receive waves of light and translate them into one of three colors: blue, green, and red.

Question 3

Weber‘s law

Answer 3

quantifying the perception of change in a given stimulus. The law states that the change in a stimulus that will be just noticeable is a constant ratio of the original stimulus.

Question 4

Bottom-up processing

Answer 4

Bottom up processing is when sensory receptors pick up signals for the brain to integrate and process.

Question 5

Wavelength

Question 6

Cochlea

Question 7

Transduction

Question 8

Top-down processing

Answer 8

information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations.

Question 9

Conduction hearing loss

Answer 9

hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea.

Question 10

Cones

Question 11

Lens

Question 12

Pitch

Question 13

Signal detection theory

Question 14

Sensory adaptation

Answer 14

When a stimulus is unchanging, you eventually become less sensitive to it.

Question 15

Depth perception

Question 16

Difference threshold

Question 17

Selective attention

Question 18

Feature detectors

Question 19

Fovea

Question 20

Sensorineural hearing loss
Nerve deafiness

Question 21

Rods

Question 22

Place theory

Question 23

Frequency theory

Question 24

Retinal disparity

Question 25

Gate control thoery

Question 26

Frequency

Question 27

Iris

Question 28

Just noticeable difference

Question 29

Poetic never

Question 30

Pupil

Question 31

Optic nerve

Question 32

Opponent process theory

Question 33

Gestalt approach and principles

Question 34

perception

Answer 34

Organizing and interpreting sensory information

Question 35

perceptual set

Answer 35

mental predisposition to perceive one thing but not another.

Question 36

schemas

Answer 36

are concepts that organize information in our experiences.

Question 37

context effect

Answer 37

has to do with top-down processing and the brain going back in time, allowing a later stimulus to determine how we perceive an earlier one.
