TRUE OR FALSE? The brain's visual system is like a camera. What we see through our
eyes is a direct window onto an objective reality. - ✔✔False
Which of the following statements about the problem of inverse optics is/are true?
A. The problem of inverse optics is underdetermined and is therefore very difficult to
solve.
B. The problem of inverse optics involves making an inference from a 3D scene (i.e. a
light source and objects in the world) to what 2D pattern of light will end up on the
retina.
C. Our perceptual system solves the problem of inverse optics by using hidden, built-in
assumptions about how the world works. - ✔✔A and C

,Based on the Ramachandran and Anstis article, which hypothesis would be preferred
by the visual system? - ✔✔A white triangle is sitting on top of another triangle and
three circles.
What is the Straight Line Assumption? - ✔✔the assumption that things tend to move in
a straight line (visual system perceives linear motion in preference to abrupt changes in
direction)
Which of the following claims is NOT made in the reading by Brian Scholl?
Because people do not typically find Bayesian reasoning intuitive inconscious decision-
making, we should doubt that the perceptual systemengages in unconscious, Bayesian
inference.
In the context of visual perception, the data is the 2D retinal image, and the hypotheses
under consideration are the possible 3D scenes in the world that may have given rise to
that image.
We should think of the perceptual system's hidden assumptions such as "there is a
single overhead light source" as Bayesian prior probabilities. - ✔✔Because people do

TRUE/FALSE: According to the reading by Brian Scholl, because Bayesian inference is
a learning method, Bayesian theories of perception and cognition are not compatible
with nativist theories that assume innate structures and knowledge. - ✔✔False
A person has damage to both the lateral geniculate nucleus AND the primary visual
cortex (V1). Which of the following would be most likely to result from this damage?
Blindsight - the person cannot consciously perceive anything, but is able to navigate
his/her surroundings.
Total Blindness
Face blindness. - ✔✔Total blindness.
Which term from the Bayes' Rule equation given in the lecture slides (e.g. slide 4-5 from
the 9/10 lecture slides) corresponds to the notion of the perceptual system's built-in
assumptions about the properties of the physical world?
P (scene | retinal patterns)
