Single Idea 18605

[filed under theme 18. Thought / D. Concepts / 4. Structure of Concepts / d. Concepts as prototypes ]

Full Idea

Instead of regularly producing a prototype out of the exemplars stored in long-term memory, it seems more efficient to extract a prototype from category members during concept learning and to use this prototype when needed.

Gist of Idea

It is more efficient to remember the prototype, than repeatedly create it from exemplars

A Reaction

[This is a critique of Barsalou's on-the-fly proposal for prototypes] If the exemplar theory is right, then some sort of summary must occur when faced with a new instance. So this thought favours prototypes against exemplars.


The 22 ideas with the same theme [concepts as built around typical examples of things]:

Many concepts lack prototypes, and complex prototypes aren't built from simple ones [Fodor]
Maybe stereotypes are a stage in concept acquisition (rather than a by-product) [Fodor]
One stereotype might be a paradigm for two difference concepts [Fodor]
Categories are characterized by distance from a prototype [Gelman]
There is no 'ideal' bird or dog, and prototypes give no information about variability [Murphy]
Prototypes are unified representations of the entire category (rather than of members) [Murphy]
The prototype theory uses observed features, but can't include their construction [Murphy]
The prototype theory handles hierarchical categories and combinations of concepts well [Murphy]
Prototypes theory of concepts is best, as a full description with weighted typical features [Murphy]
Learning concepts is forming prototypes with a knowledge structure [Murphy]
People don't just categorise by apparent similarities [Margolis/Laurence]
Many complex concepts obviously have no prototype [Margolis/Laurence]
Prototype theory categorises by computing the number of shared constituents [Margolis/Laurence]
Complex concepts have emergent properties not in the ingredient prototypes [Margolis/Laurence]
The prototype theory is probabilistic, picking something out if it has sufficient of the properties [Margolis/Laurence]
Knowing typical properties of things is especially useful in induction [Machery]
The term 'prototype' is used for both typical category members, and the representation [Machery]
Prototype theories are based on computation of similarities with the prototype [Machery]
Prototype theorists don't tell us how we select the appropriate prototype [Machery]
Maybe concepts are not the typical properties, but the ideal properties [Machery]
It is more efficient to remember the prototype, than repeatedly create it from exemplars [Machery]
The prototype view predicts that typical members are easier to categorise [Machery]
