Different people have different prototypes: prototype serves as the anchor for our conceptual knowledge. When deciding whether or not something fits into a category, you compare with the prototype in your mind and if its similar you think it is that. Sentence variation task research participants are presented with a succession of sentences; their job is to indicate whether each sentence is true or false. Interested in how quickly participants can do this task: speed of responses varies from item to item within a category, when there is much similarity they make their responses quickly, when there is little it takes longer.
