How do we represent knowledge?
representations are all over the place
a mental representation
Cognitive Psychology:
Types of Mental Representation
analogical representations: the mental image shares some of the actual features of our memory
Symbolic representation: they do not share characteristics with the subject
Analogical Representations
we are all able to construct mental images of items
you can image and bring a mental image of the space
our mental images are not the same as the real subject all the time but they do help
you can manipulate these mental images - you can think about how you can rearrange furniture
e.g. “mirror image of letter” study
the further the image is rotated from upright it takes longer
How are these representations organized?
a lot of the knowledge isn’t necessarily a mental image but rather in words
How is knowledge organized?
categorization :
concepts : the categories that we form
we can also group it together to form larger groups
Semantic Network Example
each item is associated with the other
these basic level categories are really important
they are the ones that come to mind easily
we use them every day in conversation
the things we use most often
Organization of Concepts
Defining attribute model: a rule based category
we use lists of attributes to categorize things as belonging to one group or another
Problems:
there are some attributes that may not fit so we make exceptions
