| Abstract: | Investigated the relationship between reading comprehension level, digit span, and short-term memory for Morse codelike temporal patterns in 3 experiments. Consistent with previous research on children, Exp I using 60 undergraduates demonstrated that Ss performed better when the 1st pattern was auditory than when it was visual or tactual. In Exps II and III with 36 undergraduates and 98 5th graders, respectively, no relationship was found between digit span and accuracy in comparing patterns of tones presented a few seconds apart. However, both tasks discriminated between children with normal and poor reading comprehension scores on a standardized test (Reading Comprehension subtest of the California Achievement Tests). It appears that these 2 tasks index fundamental processes that underlie reading comprehension. Digit span seems to assess an individual's ability to rapidly develop meaningful codes in memory for incoming verbal stimuli. The auditory pattern comparison procedure appears to measure ability to maintain information in short-term memory. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
