Sensation and Perception

Why is the olfactory sense neurologically unique?

• the nerve surpasses the thalamus and sends impulses directly to frontal lobe

• the receptors at the top of the nostrils connect with the cortex

• we are taught from birth to make strong connections between smells

• strong smells help us process events so we remember them

In the context of sound waves, what is the difference between amplitude and frequency?

• amplitude is the timbre of sound, frequency is pitch

• amplitude is the distance between waves, while frequency is the height of the wave

• amplitude is the height of the sound wave, while frequency is the distance between waves

• amplitude is detected in the cochlea, while frequency in the auditory cortex

the receptor of the eye that functions in dim light is the

• bipolar cell

• rod

• ganglion cell

• cone

The Young-Helmholtz theory says that

• retinal cells are excited by one color and inhibited by complementary color

• the absolute threshold is defined as the minimum amount of stimulation necessary to be detected

• there are 4 different types of cones

• there are 3 different types of color sensitive cones

Where is the first place sound waves are transduced?

• cochlea

• ossicles

• eardrum

• auditory nerve

What type of processing begins with physical sensations of stimuli that influences their interpretation?

• bottom-up

• parallel

• top-down

• psychophysical

What color has the longest wavelength?

• blue

• green

• yellow

• red

What allows you to feel movement in your toes with your eyes closed?

• nociceptors

• kinesthesis

• vestibular sense

• sensory interaction

The tendency to organize stimuli into smooth, interrupted patterns

• proximity

• closure

• continuity

• figure-ground

sensorineural haring loss is caused by

• damage to cochlea or auditory nerve

• damage to eardrum or ossicles

• broken middle ear bones

• blockage to middle ear
