Cd. Schunn et al., TO CALCULATE OR NOT TO CALCULATE - A SOURCE ACTIVATION CONFUSION MODEL OF PROBLEM FAMILIARITYS ROLE IN STRATEGY SELECTION, Journal of experimental psychology. Learning, memory, and cognition, 23(1), 1997, pp. 3-29
How do people decide whether to try to retrieve an answer to a problem
or to compute the answer by some other means? The authors report 2 ex
periments showing that this decision is based on problem familiarity r
ather than on retrievability of some answer (correct or incorrect), ev
en when problem familiarization occurred 24 hr earlier. These effects
at the level of the individual problem solver and the results reported
by L. M. Reder and F. E. Ritter (1992) are well fit with the same par
ameter values in a spreading-activation computational model of feeling
of knowing in which decisions to retrieve or compute an answer are ba
sed on the familiarity or activation levels of the problem representat
ion. The authors therefore argue that strategy selection is governed b
y a familiarity-based feeling-of-knowing process rather than by a proc
ess that uses the availability of the answer or some form of race betw
een retrieving and computing the answer.
