Experts generally solve problems in their fields more effectively than
novices because their well-structured, easily activated knowledge all
ows for efficient search of a solution space. But what happens when a
problem requires a broad search for a solution? One concern is that su
bjects with a large amount of domain knowledge may actually be at a di
sadvantage, because their knowledge may confine them to an area of the
search space in which the solution does not reside. In other words, d
omain knowledge may act as a mental set, promoting fixation in creativ
e problem-solving attempts. A series of three experiments in which an
adapted version of Mednick's (1962) remote associates task was used de
monstrates conditions under which domain knowledge may inhibit creativ
e problem solving.
