The current study used a forced choice pointing paradigm to examine whether English children aged 2 ; 1 can use abstract knowledge of the relationship between word order position and semantic roles to make an active behavioural decision when interpreting active transitive sentences with novel verbs, when the actions are identical in the target and foil video clips. The children pointed significantly above chance with novel verbs but only if the final trial was excluded. With familiar verbs the children pointed consistently above chance. Children aged 2 ; 7 did not show these tiring effects and their performance in the familiar and novel verb conditions was always equivalent.
本研究采用迫选指点范式，考察了 2 岁 11 个月的英语儿童是否能够在观看目标和干扰视频片段中动作完全相同的主动及物句时，利用词序位置和语义角色之间的关系的抽象知识，对主动及物句做出积极的行为决策。当使用新动词时，儿童在最后一次试验被排除的情况下，显著高于随机水平进行指点；而当使用熟悉动词时，儿童一直高于随机水平进行指点。2 岁 7 个月的儿童没有表现出这种疲劳效应，他们在熟悉和新动词条件下的表现始终是等同的。
