Exemplar theory is a proposal concerning the way humans categorize objects and ideas in psychology. It argues that
individuals make category judgments by comparing new stimuli with instances already stored in memory
. The instance stored in memory is the “exemplar”.

Abstract. The exemplar methodology represents a useful yet underutilized approach to studying developmental constructs. It features
an approach to research whereby individuals, entities
, or programs that exemplify the construct of interest in a particularly intense or highly developed manner compose the study sample.
What is exemplar theory of categorization?
Exemplar theory assumes that categorization is
a process of learning about the exemplars that belong to the category
. When an unfamiliar stimulus is encountered, its similarity is computed to the memory representation of every previously seen exemplar from each potentially relevant category.
What is an exemplar example?
The definition of an exemplar is person or thing that is considered as a pattern to be copied. An example of an exemplar is

Is there an exemplar theory of concepts?
The article concludes that exemplars are certainly important in some categorization judgments and in category-learning experiments, but that
there is no exemplar theory of human concepts in a broad sense
.
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 difference between example and exemplar?

What is the prototype model in psychology?
a theory of categorization proposing that people form an average of the members of a category and then use the average as a prototype for making judgments about category membership
.
What is exemplar based learning?
The exemplar-based learning model is proposed here as
an alternative approach to modeling many aspects of music cognition
. … In exemplar-based learning, such as the k-NN rule, objects are categorized by their similarity to one or more sets of stored examples, which can be represented as weighted feature vectors.
What are basic level categories?
Basic level categories, or generic level categories, are
those categories in a folk taxonomy which are most culturally salient
, and meet our basic cognitive needs the best. Basic level categories display a high degree of class inclusion and medium degree of generality, as they include subordinate level categories.
