Cog Sci 200 with 100%
correct answers
What is Cognitive Science - answer about
understanding the mind and brain —in all its
facets. It seeks deep explanations.
Why study CogSci? - answer Cognitive science
seeks detailed answers to both how and why
questions.
Processes that underlie "all mentation is
computation" - answer Storing and recalling
facts/episodes/skills Perceiving
Forming beliefs
Having desires, goals, values
Reasoning (about what to believe and to do)
Learning
Choosing
Emoting (undergoing states such as anger, fear)
Imagining
Dreaming
forward optics - answer Forward optics is the
problem of determining the 2D pattern of light that
,will fall on a set of photo receptors (such as in your
phone camera, your retina, or in a virtual world of
computer graphics), given a 3D scene and light
sources.
reverse optics - answer determining the 3D scene
that is out there given the 2D pattern of light. This
problem is underspecified.
underspecified - answer there is not enough
information in the problem input to fully determine
a unique output.
problem - answer in this sense is a computational
function, with an input and an output.
What does forward optics correlate to? - answer a
specific physical reality correlates to a specific 2-D
pattern
What does reverse optics correlate to? - answer 2-
D pattern the can potentially correspond with
multiple 3-D physical realities
natural intuitions 1 - answer We directly see what
is out there in the world.
, corresponding reality 1 - answer We see what our
brain guesses is out there, based on the 2D,
temporal stream of data received from the eyes.
natural intuition 2 - answer If it is within our visual
field, we see it. If it is not, we don't.
corresponding reality 2 - answer Our brains may
make wrong guesses; missing things that are
there, and seeing things that aren't.
natural intuition 3 - answer Seeing/perceiving is a
wholistic, con- scious process.
corresponding reality 3 - answer Seeing/perceiving
is a collection of multiple spe- cialized processes,
only some of which yield out- put that is available
to conscious awareness.
"Visual perception is an underspecified problem."
What does this mean? - answer A pattern of light
falling on the retina is consistent with multiple
external realities.
Perception - answer what your brain does when it
constructs explanations of sensory input.
