Quizizz: Sensation and Perception Lecture Checkpoint

What was the topic of yesterday's lecture and notes?

• brain chemistry and signal propagation

• memory and learning

• sensation and perception

• nature vs. nurture

What was the goal of yesterday's lecture and notes?

• prepare for an essay test

• prepare for a multiple choice test

• prepare for an oral presentation

• prepare for experiments on other students

What is the first step in a human being able to understand the sensory input that their body is receiving?

• sensing the stimuli

• transducing the stimuli

• perceiving the stimuli

• fitting the stimuli into preexisting schemata

What is the difference between transduction and sensation?

• Transduction is the process of feeling pain; sensation is the response to pain.
• Transduction is the interpretation of neural signals; sensation is the conversion of stimuli.
• Transduction involves only visual stimuli; sensation involves all other senses.
• Transduction converts stimuli into neural signals; sensation is the detection of stimuli.

Which is the better definition of sensation?

• the process of organizing, interpreting, and making sense of sensory information

• the process by which sensory organs convert physical stimuli into electrical or neural signals that can be interpreted by the brain

• initial detection of stimuli from the environment by sensory organs, such as the eyes, ears, skin, tongue, and nose

• all of the above are examples sensation

What organ(s) do you see with?

• eyes

• brain

• brain stem

• spinal cord

This is a line from yesterday's lecture:

"Eyes take light waves and turn them into impulses we perceive as sight"

What is being described in that line?

• sensation

• transduction

• perception

• Gestalt

Match the best pairings.

• eyes

• body organ for the sense of audition

• nose

• body organ for the sense of somatosensation

• skin

• body organ for the sense of vision

• ears

• body organ for the sense of olfaction

• mouth

• body organ for the sense of gustation

Step 1: The pupil and retina in the eyes take in visual stimuli/light waves.

Step 2: The retina flips the image ​ (a)   .

Step 3: The photoreceptors at the back of the eye turn the stimuli into electrical signals, or they ​ (b)   the stimuli.

Step 4: The optic nerve takes the electrical signals to the brain.

Step 5: The ​ (c)   recognizes the electrical signals as having visual sensation coding and sends the signal to the ​ (d)   , where it is ​ (e)   .
