DEVELOPMENTAL LEVEL AND CONCEPT-LEARNING--A REPLICATION AND EXTENSION.
FRIEDMAN, STANLEY R.
TO VERIFY A PREVIOUSLY OBSERVED DEVELOPMENTAL INVERSION IN PROBLEM-SOLVING ABILITY AND TO EXPLORE PROBLEM-SOLVING STRATEGIES, RESEARCHERS GAVE A SET OF SEQUENTIAL-PATTERN RECOGNITION TESTS TO 316 CHILDREN, REPRESENTING NURSERY SCHOOL THROUGH SIXTH GRADE. EACH TEST CONSISTED OF FINDING TOKENS PLACED BEHIND 5 DOORS IN A PREDETERMINED PATTERN. THE CHILDREN WERE ALLOWED 50 TRIALS TO DISCOVER THE PATTERN. THE PERCENTAGE OF CHILDREN LEARNING EACH PATTERN SHOWS AN INCREASE FROM GRADE LEVEL TO GRADE LEVEL, EXCEPT FOR AN INVERSION AT GRADE 4. THIS INVERSION, WHICH WAS NOTED IN EARLIER WORK AND HAS BEEN SEEN BY SOME OTHER EXPERIMENTERS, MAY BE DUE TO INCOMPATIBLE RATES OF DEVELOPMENT OF INFORMATION-PROCESSING AND HYPOTHESIS-GENERATING ABILITIES USED IN PROBLEM SOLVING. THE STRATEGIES WHICH THE CHILDREN WERE USING WERE INFERRED FROM THE SEQUENCES OF THEIR CHOICES. YOUNG CHILDREN TENDED TO LOOK FOR THE PREVIOUS PATTERN IN A NEW TEST. AT ABOUT THE FIRST GRADE LEVEL THEY BEGIN TO ASSUME IT WILL BE DIFFERENT. IN GENERAL, YOUNGER CHILDREN TENDED TO USE SEQUENTIAL SEARCH PATTERNS. RANDOM SEARCHING APPEARS TO BE A LATER DEVELOPMENT. THE PATTERN 1, 3, 5 WAS EASIER TO IDENTIFY THAN THE PATTERN 3, 3, 5, BECAUSE THE CHILDREN SHOWED A PREFERENCE FOR HYPOTHESES LIKE 3, 3, 5, 5 OR 3, 5, 3, 5 AND WERE VERY RELUCTANT TO ABONDON THEM. FURTHER, WHEN THEY DID ABANDON THEM, THEY TENDED TO BEGIN SEARCHING RANDOMLY RATHER THAN TO MODIFY THE HYPOTHESIS. (DR)
