Developmental change of visuo-spatial working memory in children: Quantitative evaluation through an Advanced Trail Making Test
چکیده انگلیسی

Aim: The present study aimed to investigate the developmental change in Visuo-Spatial Working Memory (VSWM) in typically developed children using a specially designed Advanced Trail Making Test for children (ATMT-C). Methods: We developed a new method for evaluating VSWM efficiency in children using a modified version ATMT to suit their shorter sustained attention. The ATMT-C consists of two parts; a number-based ATMT and a hiragana (Japanese phonogram)-based ATMT, both employing symbols familiar to young children. A total of 94 healthy participants (6–28 years of age) were enrolled in this study. Results: A non-linear developmental change of VSWM efficiency was observed in the results from the ATMT-C. In the number-based ATMT, children under 8 years of age showed a relatively rapid increase in VSWM efficiency while older children (9–12 years) had a more gradual increase in VSWM efficiency. Results from the hiragana-based ATMT-C showed a slightly delayed increase pattern in VSWM efficiency compared to the pattern from the number-based ATMT. There were no significant differences in VSWM efficiency for gender, handedness and test order. Interpretation: VSWM in children gradually matures in a non steady-state manner and there is an important stage for VSWM maturation before reaching 12 years of age. VSWM efficiency may also vary depending on developmental condition of its cognitive subsystems.
