이름대기과제와 부적점화과제에서 나타난 수학학습부진 아동의 억제 능력 = Inhibitory Function of Mathematics Underachievement Children in Naming Tasks and Negative Priming Task

국문 초록 (Abstract)

본 연구의 목적은 수학학습부진아의 수학학습부진의 원인이 억제능력의 결함에 의한 것인지, 억제능력에 대한 발달상의 지체로 인한 것인지를 확인하고자 하는 것이다. 본 연구의 피험자는 초등학교 3학년 49명, 5학년 28명으로 총 77명이며, 그 중 학습부진집단이 24명, 정상집단이 53명이다. 실험과제는 이름대기 과제와 부적점화 과제를 사용하였으며, 모든 실험은 개별적으로 실시되었다. 실험 결과, 수학학습부진 아동은 수 정보처리를 방해하는 관련 없는 정보를 억제하는 과정에 결함이 있는 것이 아니라 수 정보를 억제하는 과정의 속도가 느리기 때문에 학업 수행에서 낮은 성취를 보이는 것으로 나타났다. 또한 수학학습부진 아동들의 억제 능력은 자신의 연령보다 대략 2년 정도 지체된 것으로 나타났다.

다국어 초록 (Multilingual Abstract)

The purposes of this study was to investigate whether the mathematics underachievers could inhibition of irrelevant stimulate in naming tasks and negative priming task and they slowed developed delays those tasks. A total of 77 children, consisting of 49 children from 3rd grade and 28 children from 5th grade participated in this experiment.
The results of the study were as following. The mean response time in Quantity-Inhibition task was longer than Quantity task in all groups. The performances of 3rd grade children were lower than 5the grade. and the performance of mathematic underachievers were likely to be lower than normal controls in Quantity-Inhibition task. The mean response time in Object-Inhibition task was longer then Object task in all groups. The performance of mathematics underachivers in 5th grade was likely to be lover than normal controls. The mean response time in Objects-Shifting task was longer than in Object task in all groups. Although the differences between 3rd and 5th grade were not statistically significant. mathematics underachievers showed the tenderly of low performance than normal controls.
From the results of the negative priming task, the 3rd grade children did not show not inhibition effect. But 5the grade showed inhibition effect. Both of control groups and mathematics underachiever groups did not shown inhibition effect. These could be interpreted show that the low perform mathematics may not be affected from the deficit of inhibition but from the retardation of development.
