Describe prototype theory and its key constructs
What will be an ideal response?
Prototype theory groups things together not by their defining features but rather by their similarity to an averaged model of the category. A prototype is an abstract average of all the objects in the category we previously have encountered. That is, we have an average representation of the category, and we compare objects to that average representation (prototype) when making a decision whether or not to place them in a certain category. Objects that are prototypical of a category therefore have high family resemblance. Crucial for prototypes are characteristic features, which describe (characterize or typify) the prototype but are not necessary for it. Characteristic features commonly are present in typical examples of concepts, but they are not always present.
