Final Exam Content Flashcards
What is concept learning?
Hypothesis testing about a concept by making guesses about which attributes are essential for defining the concept
What is the problem with the hypothesis testing theory?
Role of confirmatory and disconfirmatory feedback
Participants will forget their hypothesis
What are the two parts of the hypothesis testing theory?
Conjunctive concept and disjunctive concept
What is the conjunctive concept theory?
members must possess both of two separate attributes
What is the disjunctive concept?
Members must possess either one of two separate attributes
Is the hypothesis testing theory appropriate in everyday life?
It can tell us how we might behave in a lab setting but not how we would behave and interact in everyday life, we are complex and not that simple
What is family resemblance?
members of a concept share family resemblances
What is the bird idea regarding resemblances?
These birds resemble each other somehow but how they share the resemblance may be different depending on the category
According to Rosch and Mervis (1975) members of a concept shares something in common with other members of a concept, although they may not all share the same thing
What is the superordinate level?
The most generic and inclusive level of a conceptual category is big and has the most amount of memories
What is the basic level?
Most useful level of a concept, characterized by neither too much not too little information
What is the subordinate level?
The most restrictive, specific level of a conceptual category
What are semantic networks?
A structure for how information is stored in long-term memory (semantic)
What does the strength of activation in semantic networks depend on?
Time, distance, and number of concepts activated
What are the concepts of semantic networks represented as?
Nodes
What are nodes interconnected by?
Means of links and pathways
What does activation spread from in semantic networks?
Concept to concept along connecting pathways
What does the spreading activation in semantic networks ?
related concepts
What happens when activation reaches a concept node?
It is summed up
If activation reaches a threshold what is activated?
The concept
What is semantic priming?
When concepts are activated in memory, activation spreads to semantic related concepts, making them easier to fully activate if needed
What is the classical view?
People create and use categories based on a system of rules
o Necessary and sufficient features. There is a specific feature we expect to see to help us identify something to give it semantic meaning
Defining features
What are examples of the classical view?
A chair must have legs, a plane must have wings
What are defining features?
What are the pros of the classical view?
It is easy to see how we classify novel members of a category
A very intuitive way of how we use concepts,
A very clear description of how we do this
