Midterm 1 Flashcards
What are the different fields that comprise cognitive science?
psychology, cognitive science, computer science, linguistics, anthropology, neuroscience
What role do these different fields play in cognitive science?
philosophy: raises questions, defines concepts, gives directions
psychology: focus on mental processes (learning, memory, attention)
neuroscience: focus on the brain (maps mental processes to physical structures)
computer science: creating artificial minds; defines old problems in new ways
linguistics: models language as a cognitive system
anthropology: gives a scope of human culture, behavior, & thought (how different ppl think)
Explain multiple realizability
the thesis that the same mental property, state, or event can be implemented by different physical properties, states, or events.
Why do we care about multiple realizability in cognitive science?
If the mind and the brain were the same thing, then the field of cognitive science would not be needed
Mind
information processor. According to this, it would incorporate some form of mental representation
Interdisciplinary
multiple fields comprised
Information processing
quantifying thought in terms of information
Functionalism
mental states are defined by their functional profiles
what makes something a thought, desire, pain depends not on what biology causes it but more on the physical state or function it causes the body to do
Why do we care about representations in cognitive science?
To explain how the mind interacts with the physical world
Explain what analog and digital representations are (with examples).
Digital: discrete, categorical (digital clock, color wheel)
Analog: continuous spectrum (analog clock, color spectrum)
Define and explain the differences between imagistic, symbolic, and propositional representations (with examples).
Imagistic: a mental image (when you imagine something in your mind’s eye)
Ex: dollar bill
Symbolic: something that stands for something else; relationship between them is arbitrary
Ex: $
propositional: in terms of language
Ex: “money”
What is aphantasia, and what does it tell us about mental representation?
Aphantasia: absence of mental image
It is difficult to remember events or faces of people → mental representations help us with cognition in a sense
What are Marr’s levels of explanation?
1) Computational
-What is the goal of the system
-What do you think will be accomplished after the computations?
2) Algorithmic
-What steps are taken to accomplish that goal
-What representations are created
3) Implementation
-What is the physical system that executes the steps
-How are the steps executed physically
Why do we care about Marr’s levels of explanation in cognitive science?
Breaks down understanding of how the mind receives and processes information
Give an example of a system that you could explain with Marr’s levels.
Chess:
Computational
Things needed to know
The goal
The movements
The rules; what are captures
Algorithmic
How do you win?
→ Analyze games and then create a statistical model to see the probability of winning that type of play
→ Study openings
Implementational
Can do it in their head
Weber’s law
As relative difference gets smaller, it gets harder are harder to differentiate; can perceive difference above a certain ratio
Representational Trade-off
how choosing one representation type over another may bias you towards one algorithm over another and there are a lot of choices at each level for different algorithms that can converge on a single computational goal
What is the grounding problem
If there is a “little person” in our brain viewing the world through us, there must be a little person in their brain, and so on
There is “no grounding” for this process
Compare and contrast the different types of dualism and monism. How does each approach define the mind?
monism: mental properties and physical features are identical to one another
-idealism: Everything in the universe is mental
or mentally-constructed.
-Physicalism: Everything in the universe is physical
dualism: mental properties and physical things are non-identical
-property dualism: Mind and body have different properties.
-Biological Naturalism: Mental states are not identical to brain states, but they are causally reducible to brain states.
-Epiphenomenalism: Mental states are caused by brain states, but they do not cause anything. They are causal dead ends.
-Panpsychism: Mental states are an inherent property of matter. Everything has a little bit of consciousness but it’s a spectrum.
