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
What are the cons of the classical view?
How to identify poorly defined categories such as games
What will be that one feature to make all the members a part of that category (very hard to determine this)
Graded structure: some instances of a certain concept that seem more born to the category than other ones
Most problematic: how long it would take for us to make decisions
There should be a more economical concept and rules as to why something is occurring
What is the prototype theory?
Based on similarity among members and comparison to standards
People abstract the common elements of a particular concept and then store an abstracted prototypical representation in memory
What are the pros of the prototype theory?`
Normally it would take too long to decide, but this makes decision making super quick
What are the cons of the prototype theory?
How do we come up with prototype representations when we have these poorly defined categories
What is a prototype?
Member of a conceptual category exhibiting a collection of typical features or attributes
-Average a large number of examples of the concept
What is the exemplar theory?
Instead of using one thing to represent a concept we use multiple things
People consider each encounter that they have experienced with the members of that category
Based on similarity among members and comparison to standards
Concepts are represented by a variety of exemplars
Each concept is represented by any number of specific members of the concept
What are the pros of the exemplar theory?
We don’t have to come up with one prototype that relates to everything we can just get examples
What are the cons of the prototype theory?
With this we are not able to make decisions as you are having to make multiple comparisons
What is the essentialist approach?
People have a general idea of the essence of a particular concept
Members of a category have a fundamental similarity (essence)
What is the law of effect?
If a response in a presence of a stimulus is followed by a satisfying event, the association between the stimulus and the response will be strengthened; if the response is followed by an annoying event, the association will be weakened
What did Edward Thordike do .
The puzzle box where you can trap cats, and for the cats to get out of the boxes they must solve some challenges in the box
Look up the details of this experiment and put the details into your study cards
It starts narrowing down the behaviors needed to open the box (trial and error, operant conditioning)
But not because they are learning but rather, they are learning how to get out of the box
These behaviors are explaining insight vs. Trial and error
Late 1800s
What are verbal protocols?
transcription and analysis of people’s verbalizations as they solve the problem
What are the problems with verbal protocols?
o Depends on participants’ verbal activity
o Assumes verbal report is accurate
o Thinking out loud may interfere or change the nature of thought processes
What is problem solving?
o Involves a goal-directed sequence of steps and the cognitive operations used to work through a problem in the face of constraints that must be observed and obstacles that must be overcome
What is the initial state?
Where you are right now, the state that you start off in
What is the goal state?
Where you are trying to get
What are the components of problem solving?
Initial state
Goal state
Set of rules or constraints
Set of obstacles
Ill-defined problems –> well-defined problems
What is language?
a. Highly structured symbol system that allows for creative and meaningful communication
What is psycholinguistics?
a. Discipline devoted to understanding the properties of human language and the mechanisms responsible for language acquisition
What is the mental lexicon?
a. All the words (symbols) that allow for communication and comprehension
i. Sign language counts as a spoken language as well only way it isn’t is that it isn’t spoken
ii. Dimensions of semantic memory
iii. Each representation includes not only the meaning but also other information about the word (sound, written form, roles it can take in a sentence, etc.)
What is the lexical access?
Process by which a concept is activated within the lexicon
What are Hocketts features of language?
Semanticity, arbitrariness, displacement, prevarication, reflectiveness, productivity,
What is semanticity>
- Elements of language convey meaning
a. The relationship between the symbols and the meaning is completely arbitrary
What is arbitrariness?
- The connections between linguistic units and concepts or meanings referred to by those units are entirely arbitrary
What is displacement
Language allows us to talk about times other than the immediate present
What is prevarication?
the ability that language allows us for misrepresentation and deception
