Question 2.
(a) How many pieces of information in total does Jane remember about the spheres?
19 x 2 = 38 pieces of information in total (19 items times 2 features (size and shade))

(b) How many pieces of information in total does Jill remember about the spheres?
19 + 8 = 27 pieces of information in total (19 items’ categories + 2 features per 4 categories (8))

(c) How are categories useful? Answer this question by describing one advantage of Jill’s strategy compared to Jane’s.
Jill's strategy is more efficient because fewer pieces of information are required to specify the category and store it in memory than to store a complete description.
Moreover, aside from conserving memory storage requirements, Jill’s strategy also has an advantage of the reduced need for learning (Bruner, Goodnow, & Austin, 1956). Also, Jill will likely maintain efficient long-term representations by preserving category-level information rather than individual-level information.

(d) How can categories be harmful? Answer this question by describing one disadvantage of Jill’s strategy compared to Jane’s.
A disadvantage of Jill’s strategy compared to Jane’s is that by using category-level information, she might occasionally overgeneralize and make errors. Her reproductions will likely reflect a compromise between the stimulus itself and the category to which it belongs, and with time delays, the contribution of category-level information relative to individual-level information increases, so individual nuances might be lost (Huttenlocher, Hedges, and Vevea, 2000).
