ABSTRACT

Children’s memory responses to a target location in a homogenous space change from being biased toward the midline of the space to being biased away. According to Dynamic Field Theory (DFT), improvement in the perception of the midline symmetry axis contributes to this transition. Simulations of DFT using a 3-year-old parameter setting showed that memory biases at intermediate target locations were related to the perception of midline. Empirical results indicated that better perception of midline was associated with greater memory biases away at the 20° and 40° targets in 3-year-olds, and greater biases away at 60º in 4- to 6-year-olds. Findings support the DFT in that perception of midline is associated with memory biases.

摘要

儿童对同一个空间中目标位置的记忆反应从偏向空间中线变为偏向中线。根据动态场论（DFT），对中线对称轴的感知能力的改善有助于这种过渡。使用3年的参数设置的DFT模拟显示，中间目标位置的记忆偏差与中线感知有关。实证结果表明，对中线的更好感知与3岁儿童在20°和40°目标处的较大记忆偏差以及4至6岁儿童在60º处的较大偏差有关。研究结果支持DFT，因为对中线的感知与记忆偏差有关。
