Grouping

A

Tendency to organize stimuli into coherent groups

19
Q

Visual cliff

A

Laboratory device for testing Depth perception in infants

20
Q

Shape and size constancies

A

We perceive the form of familiar objects as constant even while our retinas perceive changing images of them

21
Q

Sensorineural hearing loss

A

Damage in your inner ear (tiny hair cells)

22
Q

Conduction hearing loss

A

Anatomical structure in the ear block the passage of sound

23
Q

Cochlea

A

Sound waves traveling through the cochlea fluid trigger nerve impulses

24
Q

Gate control theory

A

The theory that the spinal cord contains a neurological gate that blocks pain signals or allows them to pass on to the brain

25
Vestibular sense
Our sense of body movement and position that enables our sense of balance
