Exemplar and prototype theory. ... While a prototype is an abstract average of the members of a category, an exemplar is an actual member of a category, pulled from memory. While prototypes are economical—meaning they are more conducive to quick judgments—exemplars are less so.
What is the exemplar model?
Exemplar models are a successful class of psychological process mod- els that use an inventory of stored examples to solve prob- lems such as identification, categorization and function learn- ing.
What is a prototype representation?
Prototype theories make a simple assumption about concept representation, namely that the concept is represented as the ‘ideal’ or ‘average’ category exemplar. Thus, representations of specific category exemplars do not influence classification.
How do prototypes differ from exemplars quizlet?
The exemplar approach is very similar to the prototype approach except where the prototype approach uses one single default member as the prototype, the exemplar approach uses each member of the group as an exemplar and objects can be compared to other exemplars and the more exemplars of a group the object matches the ...
What are prototypes in psychology?
A prototype is a mental representation that serves as a cognitive reference point for the category . The most salient features of the prototype are the first features that come to mind when the category is mentioned. The effects that prototypes have on categorization are referred to as prototype effects.
What are some examples of prototypes?
- Sketches and diagrams. ...
- 3D printing or rapid model. ...
- Physical model. ...
- Wireframe. ...
- Role-play through virtual or augmented reality. ...
- Feasibility. ...
- Working Model. ...
- Video Prototype.
How do prototypes affect thinking?
Prototyping helps us organize and interpret vast information we receive from the outside world . Prototype allows us to take shortcuts and make quick judgement and decisions. On the other hand, it may sometimes block some new information and force us to focus on our pre-existing ideas, making us less open and flexible.
What does exemplar mean?
: one that serves as a model or example : such as. a : an ideal model. b : a typical or standard specimen an exemplar of medieval architecture. c : a copy of a book or writing.
What is an example of an exemplar?

An example of an exemplar is a copy of a manuscript. A person or thing regarded as worthy of imitation; model; pattern; archetype.
What is exemplar memory?
The term “exemplar memory” is most often used to account for the results of experiments in which it is evident that specific details of the discriminative stimuli are remembered.
What is the purpose of a prototype?
A prototype is a representation of a design produced before the final solution exists . It allows you and potentially your future customers to understand the product. Prototype models are often used for photo shoots, trade shows and exhibitions, customer feedback, and design verification purposes.
Why do we need a prototype?
The most important advantage of a prototype is that it simulates the real and future product . It can help attract customers to invest in the product before allocating any resources needed for implementation. You can test the design’s correctness before it comes into production and you can discover design errors.
What is a better prototype for a bird?
A prototype is a cognitive reference point, i.e the proto-image of all representatives of the meaning of a word or of a category. Thus, a robin or a sparrow can be regarded as a prototype or a “good example” of the category bird, whereas a penguin or an ostrich is a rather “bad example” of this category.
What is the main difference between prototypes and exemplars?
While a prototype is an abstract average of the members of a category, an exemplar is an actual member of a category, pulled from memory. While prototypes are economical —meaning they are more conducive to quick judgments—exemplars are less so.
What is an advantage of using prototypes to identify objects?
• Prototypes may work best for larger categories . Typicality Effect . individuals respond more quickly to typical examples of a category than they would to examples that are considered atypical. High Typicality. High typicality means that a category member closely resembles the category prototype.
What is the benefit of an exemplar quizlet?
The advantages of using exemplars are exemplar approach to categorization can explain our behavior just like the prototype approach, and it can account for being able to categorize an object that is atypical .
