Development of Problem-Solving Strategies in Repeated Sentence-Verification Tasks
This experiment was designed to investigate the development of problem-solving strategies by subjects in a sentence-verification paradigm which permitted repeated exposure to problems of the same type. While it was predicted that subjects would show a general improvement across trials as a function of repeated exposure to similar sets of problems, nevertheless it was predicted that some types of problem would show little or no improvement across trials, while other problems would show significant improvement as the subjects determined more efficient strategies to use to aid in rapid solutions. The results illustrate that certain types of sentence-verification tasks allow the development of efficient strategies which significantly decrease reaction times across trials, while other problem types produce uniform response rates across problem sets with negligible improvement as a function of practice. The results ate interpreted in terms of the relative availability of problem-solving strategies for the different types of verification task.
