Cogsci Lecture (January 5)
Saturday, January 17, 2015
The theory of cognition as computation came out of the scientific revolution.
To think is to compute. The mind manipulates abstract symbolic
equations in a logical manner.

Problem: computation doesn't capture relevance well. But relevance is central to
Therefore: computation is insufficient for realizing AI.

2nd gen cogsci: connectionism.
Fundamental assumption of 1st gen: cognition is language-like.
2nd gen: cognition is not language like.
What is the relationship between cognition and language?

How does a cognitive system determine what is relevant in a situation?
Anything can be relevant to a particular topic? How do we get there without searching our whole memory?
We try to prespecify how things will

Recall Elizabeth Potter: the selection process that helps us pick out relevant information from
our memory works in similar way to problem solving, from lecture 5:

Cognitive Science Lecture 5
Last class the alternative proposal, instead of trying to analyze, formalize, mechanize, perhaps a
better way to do that is memory.
About memory, we believe it is essential to all the theories we have looked at so far.

What is Cognitive Science?
Term mind, there are many different levels of analysis for this word
Mind, cognition, brain, are not just 1 level.
Treating mind and brain interchangeably turns to be problematic.
Cognitive Science Lecture 2
Science is the opposite of common sense.
Philosophy is the discipline of challenging common sense.
Common sense use the familiar to explain the unfamiliar.
Science use the unfamiliar to explain the familiar. (This table? Its
Lecture 1 (Sept.14th)
There are many disciplines that attempt to define & describe what the mind is. The goal of cognitive
science is to figure out what the relationship between these different disciplines is.
Brain biology, neuroscience, chemistry

Concepts are to their categorical entities; the way a theory is to all of its data.
Using mini-theories to build one main theory that explains categorization.
What are the advantages of this view?
