Research on expertise has repeatedly documented that experts learn new info
rmation better than do novices, but only when the information is relevant t
o the expert's domain. It was found in Experiment I that participants showe
d superior learning and recall of a large quantity of new, non-domain-relev
ant facts about concepts within their domain of high knowledge than about c
oncepts for which they had low domain knowledge. Experiment 2 investigated
whether the participants' superior recall of new facts related to concepts
within their domain of high knowledge was due to the number of prior facts
associated with the concept or to the prior frequency of repetition of thos
e concepts. It was found that participants' recall of new facts was better
for concepts with 5 prior associated facts than for concepts with a single
prior association but that the number of previous repetitions of each conce
pt did not affect the level of recall for the new facts.
