The development of short-term memory span from 8 to 16-year-old children / 中华行为医学与脑科学杂志

ABSTRACT

Objective To study the characteristic of 8 to 16-year-old children's short-term memory.Methods 157 subjects participated in this study (8,10,12,14 and 16 years old).All subjects completed the digit recall,word recall,spatial recall and position recall tests.Results Short-term memory spans increased with age (F(4,145)= 35.56,P<0.01) and peaked at 14 years old [ digit (8.83±1.31),word (4.79±0.68),spatial (5.90±0.77),position (5.42±1.28)].Conclusion The developmental trends of four tasks' memory span were similar.But the exact span-scores were different from what Pascual-Leone's model predicted.
