MCAT KHAN ACADEMY EXAM AND
ANSWERS.
Visual Cues - Answers-
Depth - Answers-Retinal disparity: eyes gives us slightly different views of objects since
eyes are 2.5 in apart and puts image together
Convergence - Answers-Ability to look at objects far away and eye muscles are relaxed
Monocular cues - Answers-Relative cues: One eye that perceive bigger object to be
closer to us (ex. bigger ant perceived to be closer than smaller ant even though they are
the same size)
Interposition: (ex. rectangle shape in front of circle; we perceive rectangle to be closer)
Relative height: objects perceived to be higher are further away vs. objects lower
perceived to be closer
Motion parallax: (ex. when driving in desert, mountain far away perceived to be moving
slower than objects close to the car that seem to move very fast)
Constancy - Answers-Shape constancy: (ex. understand door is rectangular even if it is
"changing shape" while being opened in front of us)
Color constancy: (ex. red cup is partially dark in one side due to lighting, but is still red)
Size constancy: (ex. person further away appears to be smaller, but still same size as
person closer to us)
Sensory Adaptation - Answers-Change in sensitivity of your perception of a sensation
examples:
Hearing: loud noise makes inner ear muscles contract to protect it from damage
Touch and smell: desensitized over time
Proprioception: if given goggles that flip images upside down, brain starts to flip it back
to normal
Sight: depending on dark vs. light, pupils dilate or constrict
Gestalt Principles - Answers-
Law of Similarity - Answers-Item that are similar are grouped together
Law of Pragranz - Answers-reality is reduced to simplest form
