Knowing and Using Knowledge Flashcards
Who is Soloman Shereshenvsy and why is he unique?
A mnemonist can encode and retrieve information quickly and can never forget anything/gave perfect retellings. One struggle is having difficulty tying/using the information together.
General knowledge that we have is a ________.
Concept
What did Wittgenstein (1953) propose?
Simple terms we use every day do not have definitions because not all concepts are the same since there are exceptions. (e.g) A dog with no tail
Members of a category resemble one another, with some number of features being shared by any subset of a category member though the features may not be shared with all members.
Family Resemblance
(e.g.) Three-legged dog, it still barks + has a tail, also siblings
A single best example or average. Identifying the center of the category.
Ideal
Objects, situations, or events differ in ______ from the prototype/how close to it is.
Typicality
Objects, situations, or events closer to the prototype are high in typicality and are better members than those farther from the prototype.
Graded Membership
Smith et al. (1974)
Sentence verification. True or false sentences and reaction time were faster if the item was close to the prototype.
Mervis et al. (1976)
Production task. Beginning list was high in typicality and closer to the prototype
Mervis et al. (1976)
Production task. Beginning list was high in typicality and closer to the prototype
A level of categorization that is not too specific or too general. This is the same level as where prototypes are located and where children first learn. (e.g.) Spoon
Basic Level
What was the outcome of Tanka and Taylor (1991)?
Those who were experts were able to give specific detailed responses to their subjects while novice people gave basic responses, such as, “this is a bird”.
What is an example of an object being at the superordinate level?
Cutlery
What is an example of an object being at the subordinate level?
Soup Spoon
What did Halberstadt & Rhodes (2003) say about typicality and attractiveness?
Our prototypes are most attractive when we think about them because it is high in typicality.
Specific remembered instances; an example from past experiences. (e.g.) a chair that a grandparent used to sit in.
Exemplars
Keli (1986)
Differences in typicality and categorization
What happens if your Hubs are damaged?
Your general knowledge about a concept diminishes.
Murphy & Medin (1985)
Asked if a lawnmower and plum are in the same category
Category knowledge guides your _______ about new cases and _____ your inferences.
Thinking; Guides
Typical exemplars promote stronger inference about their broader category than atypical exemplars.
Typicality Effect
The better the example fits the category the more likely were are to use it to explain _________.
Atypical Situations
If the example does not fit then what?
It is not used or remembered.
When we have something unusual like an infectious disease, you’re more likely to think of a sparrow spreading the disease than a duck because it is not typical.
Rips (1975)
We will choose a common/well-known answer like “robin” because it is typical.
Osherson et al. (1990)
What makes stereotypes different from prototypes?
Strong emotional feeling associated with a category
Students at your university have a lot of diversity than other universities, regardless if they are the same.
Rithegeber (1977)
We assume individuals in our group have a lot of diversity, but not those in the out-group because they are all the “same”.
Homogeneity Effect
The lateral occipital cortex
Living things and perceptual properties, such as, how it looks.
The medial fusiform gyrus
Nonliving things and focuses on the function of it.
A condition that involves difficulty naming things, but has no issue with speech. This condition only applies to living things and is based on the area where the brain damage occurred.
Anomia
Concepts are essentially grounded in perception and action.
Embodied Concepts
Hub
A brain location that connects and integrates information from many other areas of the brain.
Spokes
More specific elements of the concept
Weights between connections signify strength
Connectionist Network Model (aka PDP)
Longer to transverse the hierarchy.
Collins & Quillian (1969)
Reproductive Memory
Verbatim
Reconstructive Memory
Opinions and reformatted
What 3 trends did Bartlett (1932) find?
Recalled the main plot, minor details were not remembered, and successive recall was normalized/rationalize.
