What is a model?
-simplification of complex phenomenon. Small details left out.
-simulation provides us with data. This data is a prediction.
What is a cognitive model
-cogni sci makes models of how the mind works.
-categorization: make computer simulations that can properly classify different objects or animals.
-controlled task: all things you learned are not brought into experiment. Want consistent results from all
-then modify the task and see if it effects the outcome of performance.
-statistics allow to see if significant differences are found.
-then compare human and computer models. Closer computer is to humans the better.
Cognitive architecture
-programming language for how to make a model
-gives an example of how different types of memory work.
-one model has more processing steps than another.
-two different models about the same system.
-even though models are different, predictions turn out the same. This happens because all the parts
can be slightly different yet accomplish the same goal.
Kinds of Cognitive architectures
-symbolic: runs on a level of processing symbols
-sub symbolic: runs on a level below
What’s a symbol
-symbols represent concepts.
-A represents the first letter of alphabet, grade etc…
-symbols have meanings and that is in your head.
-at sub symbolic level you look at how symbols are formed
Symbolic Architectures
-production system: model that uses symbols.
-in our minds we have if/then rules. Allows us to act in certain behaviour in certain circumstances.
-if production fails than there’s no firing and the end action is not completed.
Typical characteristics of symbolic architecture
-HM cant make new long term memories due to brain injuries.
-able to learn tasks however.
-they trained HM how to draw in front of mirror. Every day he would still remember how to do it even
though he forgot many other things.
-goal system is built into declarative memory. Create if/then rules in declarative memory. Ex: if hand
goes wrong way, then change direction etc…
