Document Summary

Concept metal representation of an object, event or idea. Categories refer to these clusters of interrelated concepts. We form these groups using a process called categorization. Cognition mental processes involved in acquiring and using knowledge. Categorization is difficult to define in that it involves elements of perception, Memory and higher order processes like decision making. Classical categorization theory claims that objects or events are categorized according to a certain set of rules or by a specific set of features. Uses a behavioural measure known as sentence verification technique. Sentence verification show us that some members of a category are recognized faster than others. Graded membership observation that some concepts appear to make better category members than others. Prototypes are mental representations of an average category member. If you took an average of the 3 most familiar birds, you would get a prototype.
