Provide an example off furniture and levels of abstraction hierarchy
Furniture-> chair-> armchair, lounge chair
What is the middle level of level of abstraction?
Basic level
How are basic levels significant?
General agreement on hierarchies
Top level of level of abstraction
Superordinate level
Bottom level of levels of abstraction
Subordinate level
Out of the list “clothes, pants, jeans” what is which level? What are each unique properties?
Superordinate: clothes- fabric to cover body
Basic: pants- two tubes to wear on legs, cover entire legs
Subordinate: jeans- denim
Members of ____ level categories share significantly more attirbutes than those of superordinate categories
Basic
Basic levels share enough attributes so that moving to a subordinate level is often?
Necessary, optimally cohesive enough compared to specific level (TMI)
How were conceptual hierarchies discovered originally? In what domain?
Antropology, not psychology
Describe the fidnings of Berlin et al and”oak” and “squirrels”
Different cultures label animals and plants found most agreement at basic level. Labels like oak and squirrels are more easily translated across cultures than “white oak” or “black squirrel”
Basic levels are usually how many words compared to subordinate?
Basic are one, subordinate are two
Describe the “white oak thrips” inference study
Ask if all oaks have thrips in US and Mayan culture. Gave a property of a subordinate level (species) and asked if it generalized to basic level (oak) and superordinate level (tree) and higher superordinate level (plant). People in both cultures believe both white oaks and oaks could have the disease but not plants and trees
What do we typically categorize things by?
Occasionally by appearance, but primarily essentialists
Provide evidence of essentialism in 3 to 4 year olds
Taught 3 to 4 year olds a novel property of a familiar animal or object (cats see in the dark). Children were then asked whether each of the four test items possessed the property. The items varied by category membership (same and different) and appearance (same and different). Showed different types of cats and skunk (similar appearance, different essence), and dinosaur (both different). Found that children almost always said that same category membership lead to children inferring they see in the dark but not different appearance
Provide an example of the Keil mouse and squirrel study/ racoon and skunk study
Mouse wears a squirrel outfit and raccoon undergoes a surgery to become a skunk. Both children and adults assume that the mouse outfit squirrel is still a squirrel, however children believe the raccoon becomes a skunk, compared to adults. Some changes were temporary and some permanent. Young children thought permanent changes could alter an animal’s identity but not temporary ones. We categorize entities based on their essential properties but must learn what fixes a categories’ essence
Trying to infer the properties of one category on the basis of another animal (coelacanth and animal
Category based induction
Describe the robin bones vs ostritches and sparrows test.
Robin has sesamoid bones, therefore sparrows/ostriches have sesamoid bones- assume sparrow because ostritches tend to be an outlier within birds/share less properties
Describe coverage in robins and ostriches bones
Robin/ostritch has sesamoid bones therefore all birds do- assume robin because robin is the most similar/covers more of the category of bird
What were some weaknesses of similarity coverage model studies?
Were built from judgement of unfamiliar properties or blank properties- properties were meaningless to participants, but we do have knowledge of properties, framing of argument can change opinion/ categorization
Describe knowledge effects in tunas, bears vs whales with livers and swimming patterns
Assume bears have two layered livers therefore whales do while behavioral property is similar in same location (tuna and whales).
Describe framing effects in carrots and rabbits and enzymes
Carrots have enzyme x therefore rabbit have enzyme x, rabbits have enzyme x therefore carrots have enzyme. Both contain the same categories so similarity coverage is equated, but only a is suggestive of causal relation
What is the benefits of Bayesian induction?
Can organize based on the structure of the domain, sensitive to a domain’s causal structure, can learn underlying causal structures that represent which domains (matrix,line,e tc)
What are analogies able to facilitate
Problem solving
Categorization
Communication
Conceptual change
Explanation
Describe Darwin and analogies
analogy between the evolution of the earth and the evolution of species
