On Comparing Error Patterns and the Effect of Maturation in a Unit on Sentential Logic
The research literature dealing with critical thinking vis-à-vis formal logic implies that (a) an individual's reasoning ability seems to improve with age and (b) reasoning from negatively worded hypotheses is more difficult than reasoning from positively worded hypotheses. The purpose of this study was to investigate these two implications.A test consisting of 30 items in sentential logic was constructed and given to elementary school children and prospective elementary school teachers. The findings indicate that only on certain forms of questions is maturation a factor in logical reasoning ability. Indeed, with certain types of items in sentential logic, maturation–and, inseparably, education–seems to be a hindrance to logical reasoning.
