Psych Unit 4 Recap

What is the psychological process by which we interpret sensory stimulation?

• Sensation

• Absolute Threshold

• Difference Threshold

• Perception

What allows people to become less sensitive to unchanging stimuli?

• sensory adaptation

• difference threshold

• visual acuity

• blind spot

What does signal detection theory take into account?

• The lowest sounds that people can hear.

• How psychological factors affect perception

• Which cues are the most effective for showing depth

• People's favorite colors

What does the process of sensory adaptation teach us?

• To block out sounds we hear frequently

• To ignore sounds that are unfamiliar

• To notice sounds we hear frequently

• To pay closer attention to familiar images

Select the example that describes SENSORY ADAPTATION.

• When you hold someone's hand, you don't get used to the pressure of that hand in yours.

• When at the beach, you become less aware of the sound of the waves.

• When it is cold outside, your body is unable to adjust to the temperature.

• When in pain, your brain is alerted to the origin of the pain and its severity.

What is one cause of color blindness?

• Too many rods

• Sudden, bright light

• Malfunction in the cones

• Damage to the olfactory nerve

After the pinna collects the sound, where does the sound "go" next in the auditory process?

• The sound reaches the eardrum, which vibrates when sound strikes it.

• In response to the pinna, neurons in the cochlea vibrate.

• The auditory information is projected onto the cerebral cortex.

• Three small bones vibrate in the middle ear.

What causes sounds?

• electromagnetic waves

• the release of sensory neurons

• movement that causes changes in air placement

• vibrations that cause changes in air pressure

What is the gateway from the outer ear to the middle ear?

• Stirrup

• Eardrum

• Cochlea

• Anvil

What is the function of the auditory nerve?

• To move sounds away from the olfactory nerve

• To make up for a lack of rods

• To adjust color blindness

• To transmit neural impulses from the cochlea to the brain
