摘要: 计时指判断时距的长短, 计数指辨别刺激呈现数目的多少。研究者发现计时和计数具有相似性, 表现在类似的基本原理, 对时间和数目的记忆都受到时间延迟的影响, 跨通道效应类似, 而且药物对它们的影响一致。模式控制模型认为计时和计数共享同一机制, 量值理论的观点是时间和数目等不同维度具有部分重叠的同一表征形式。计时和计数都激活了前额、顶叶、小脑等区域, 但两者在行为结果和激活的脑区上也有部分差异。计时和计数具有同一表征还是两者独立加工, 只在对比反应阶段存在共同机制仍需要进一步研究。

Abstract: Timing refers to duration discrimination, and counting refers to number discrimination. There are some similarities that they have same principles, and that the memory of time and number are affected by time dalay, and that cross-modal and drugs play consistent roles. Based on Mode-control model, timing and counting share common mechanism. The viewpoint of Magnitude theory is that time and number possess the partial overlapping mental representation. The brain areas are involved prefrontal, parietal, cerebellum and basic ganglia. Many evidences have indicated timing and counting have some same properties as well as divergences. However the possibility whether there is shared common magnitude representation or their mutual action occurs response selection stages needs to be researched further.
