The Origin of Information and Its Effect on Problem Solving.
Hanley, Gerard L.
The difference in cognitive resources required for imagination and perception was tested in two experiments by examining the reduced substitutability of imagination and perception in problem solving by college undergraduates. Eighty subjects in Experiment 1 drew capital letters from lines or descriptions of lines in a seven-page booklet. The results indicate that imagined information and perceived information were integrated with equivalent accuracy and strategies. When the problems became more cognitively demanding and mental combinations of lines into figures contained four elements, different strategies were used. Sixty-eight subjects were given explicit instructions on how to identify imagined or perceived lines as letters. When strategies were restricted, integrating imagined information was less accurate than integrating perceived information. Several factors, many of which were related to the cognitive demand difference from these two origins, influence the substitutability of imagination and perception. To describe cognitive processing of information from internal and external origins, researchers should use multiple performance measures. (SLD)
