Problem 2 Flashcards
What is categorization ?
It refers to a process through which objects are sorted and classified
–> linking higher cognition to perception
There are 3 different categorization systems, each being associated with different memory systems.
What are they called ?
- WM/ rule-based categorization system
- Explicit LTM/ similarity-based categorization system
- Implicit LTM categorization system
WM/rule-based categorization system
Decides whether a certain item belongs to a category by determining whether the item fits a certain rule that defines the category
Explicit LTM/ similarity-based categorization system
Decides whether a certain item belongs to a category by determining the item’s similarity to remembered exemplars of the category
Implicit LTM categorization system
Decides whether a certain item belongs to a category by assessing the ease at which its perceptual features can be processed
–> the greater the perceptual fluency the greater the likelihood of membership
Why can categorization sometimes occur in “fuzzy sets” ?
Because categories may not always be fully bound to a particular context but may be diffused to different types of situations or contexts
–> objects may belong to one or more concepts, in varying degrees of fitness
ex.: a “fox” may belong to the category “dog” but not to the same degree as “wolf”
Which factors play an extensive role when learning to categorize ?
- Language
- Culture
- Personal associations
- Priming
- Experience
Why do we categorize ?
1. Cognitive economy
- our minds are not capable of treating every object as unique
2. Minimizes the differences among members within a category + maximizes the differences between different categories
Do people from western vs eastern societies categorize differently ?
Yes, eastern categorization is more holistic, whereas western categorization seems to be more analytic
Anthropocentrism refers to the tendency to regard humankind as the central or most important element of existence, especially as opposed to God or animals.
Which factors influence/induce a more anthropocentric view vs a lesser one ?
More:
- Receiving less input about other species
ex. : not owning pets, living in the city - Receiving more input about theories of psychological causality for humans
Less:
Being more holistic
–> more likely see humans + nature as one
When does anthropocentric reasoning start ?
How long does it persist ?
It usually starts between the ages of 5-7, and is said to stop at the age of 10
–> it can persist in adulthood though
What is essentialism ?
A belief that things have a set of characteristics which make them what they are
–> view that for any specific entity there is a set of attributes which are necessary to its identity and function
Essentialist theory of race
Is a belief that race is a real entity that consists of underlying essence, determining a person’s disposition and is characterized by clear, unalterable physical + psychological markers
Prototype based approach
Proposes the existence of mental prototypes/family resemblance
–> objects more similar to the prototype/typical are identified faster
ex.: would rather classify an eagle as a bird than a pinguin
(explicit LTM)
BUT: fuzzy borders !
Classical approach
All examples or instances of a concept share fundamental characteristics or features that are individually necessary + collectively sufficient
–> rigid, clearly defined, rule-based
