General Knowledge (Chpt.8) Flashcards
Representation of Knowledge
LTM representation of knowledge one big issue is it always words compare propositions
Whorfian Hypothesis
LTM information is words
Testing Whorf
The dani tribe of new guinea has only two color words for light and dark but Rosch showed they remember and recognize color equally as well as english speakers Remembered color and words to the color. LTM representation is not always words recognition of central colors.
Prototype
(Rosch) central colors so why not central concept members. Typical of concepts in the same way that central colors are typical colors
Network models
Collins and Loftus spreading activation model
Semantic distance
accounts for typically reaction time accounts for semantic priming
Lexical decision task
when you differentiate a real word from non-words is it in your lexicon (meaning mental dictionary)
Anderson’s Adaptive control of thought-Rational
ACT-R
a general cognitive processing model structure and architecture. Explains cognitive models
Declarative memory
Declaring semantic and episodic memory
Inference
refers to the logical interpretations and conclusions that were never part of the original stimulus material
Semantic memory
refers to our organized knowledge about the world
Episodic memory
information about events that happen to us
Category
is a set of objects that belong together
Concept
to refer to your mental representations of a category
Situated Cognition Approach
we make use of information in the immediate environment or situation
Prototype
Is the item that is the best , most typical example of a category a prototype therefore is the ideal representative of this category
Prototype Approach
You decide whether a particular item belongs to a category by comparing this item with a prototype
Proto typically
or the degree to which they are representative of their catgory
Graded Structure
begins with the most representative or prototypical members and it continues on through the category’s non prototypical members
- Prototypes are supplied as examples of a category
- Prototypes are judged more quickly than non prototypes, after semantic priming.
- Prototypes share attributes in a family resemblance category
Semantic priming effect
means that people respond faster to an item if it was preceded by an item with similar meaning
