In class, we discussed research on young children who were experts in particular areas. The results of this research suggest that:

a. young experts are no more sophisticated at categorization in the domain for which they are expert than are young nonexperts
b. young experts tend to be very sophisticated at categorization in the domain for which they are expert, but not in other areas
c. there is an advantage for young experts over young nonexperts for the biological domain (e.g., dinosaurs), but not for other domains (e.g., chess)
d. children who are experts in particular areas tend to have better categorization skills across a wide range of areas, including ones far outside their area of expertise

Answer: b. young experts tend to be very sophisticated at categorization in the domain for which they are expert, but not in other areas
