Résumé
Investigated the internal representations used by experienced users of mathematics to encode algebraic expressions. Initially, a memory recognition task was conducted that examined the role of mathematical syntax in the encoding of algebraic expressions. Results indicate that participants (N = 24; aged 18-35 yrs) could more readily identify those parts of a previously seen expression that were syntactically well formed than those that were not well formed, suggesting that syntax plays an important role. To determine the level of syntactic structure involved, a second recognition task was conducted. Results indicate that algebraic expressions are encoded into components that represent the phrasal constituents of the expression. The results of these experiments did not rule out the possibility that the visual processes of perceptual organization were used to encode the expressions, or that the data were a consequence of a mathematical "lexicon" of common mathematical "phrases". Three further experiments were conducted to examine this, the results of which indicate that the encoding of algebraic expressions is based primarily on processes that occur beyond the level of visual or "lexical" processing. This is consistent with the finding that syntactic structure plays a key role. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
