Lab Assignment #9: Prototypes & Research Project Abstract

You have two goals in this lab. The first is to complete the Prototypes experiment in CogLab and answer 5 questions about it. Your second goal is to write an APA-style Abstract for your research project that summarizes all aspects of your experiment.

A. Complete the Prototypes experiment in CogLab and answer the following questions in a Word document.

1. Briefly explain then idea of a prototype in the context of theories of categorization, and give one concrete example (other than dogs or trees).

2. In the present experiment, what stimuli and what pattern of data are used to test the prototype hypothesis (i.e., the operation of a prototype in categorization)?

3. Do your data show a prototype effect? Briefly explain why or why not.

4. Some researchers have argued that, rather than prototypes, categorization may often be based on exemplars. Briefly describe the exemplar theory, and then explain how it could account for the "prototype effect" that is typically observed in this experiment.

5. Describe a way the current experiment could be changed so as to strengthen the size of the prototype effect.

B. Write an APA-formatted Abstract for your research project.

❑ Remember that the goal of an Abstract is to provide a brief (> Name your file "Lab9-yourlastname.doc" and mail it to the TA by 5pm this Friday.
