DOI: 10.3922/j.psns.2012.2.06 Memory performance in Brazilian school-age children

The purpose of the present study was to investigate different memory systems among children of different school ages. Ninety children who attend schools within the Rio de Janeiro municipality school system, ages 6 to 10 years, were studied. The study excluded children with learning disabilities. All children underwent a neuropsychological evaluation. A two-way analysis of variance revealed significant gender differences in the free delay episodic memory. Age differences were found for the free delay episodic memory and recognition on the Rey Auditory Verbal Learning Test (RAVLT) as well as the recall of the Rey Figure. Semantic memory correlated with Semantic Verbal Fluency. Working Memory as measured by Digit Span subtest of the WISC correlated with the first list learning of the RAVLT. Overall, study results indicated a lower performance among 6-year-old children and gender differences in children 8 and 10 years of age. Data are consistent with the literature and show a distinction in the evolution of different memory systems throughout life
