The present study examined the links between haptic word processing speed, vocabulary, and inhibitory control among bilingual children. Three main hypotheses were tested: faster haptic processing speed, measured by the Computerized Comprehension Task at age 1;11, would be associated with larger concurrent vocabulary and greater longitudinal vocabulary growth. Second, early vocabulary size would be associated with greater vocabulary growth at 3;0 and 5;0. Finally, faster haptic processing speed would be associated with greater concurrent inhibitory control, as measured by the Shape Stroop Task. The results revealed that haptic processing speed was associated with concurrent vocabulary, but not predictive of later language skills. Also, early decontextualized vocabulary was predictive of vocabulary at 3;0. Finally, haptic processing speed measured in the non-dominant language was associated with inhibitory control. These results provide insight on the mechanisms of lexical retrieval in young bilinguals and expand previous research on haptic word processing and vocabulary development.

本研究调查了双语儿童的触觉文字处理速度、词汇量和抑制控制之间的联系。测试了三个主要假设：更快的触觉处理速度（通过 1;11 岁时的计算机理解任务测量）将与更大的并发词汇量和更大的纵向词汇量增长相关。其次，早期的词汇量与 3;0 和 5;0 时词汇量的增长有关。最后，更快的触觉处理速度将与更大的并发抑制控制相关联，正如 Shape Stroop 任务所测量的那样。结果显示，触觉处理速度与并发词汇量相关，但不能预测后续的语言技能。此外，早期脱离语境的词汇量可以预测 3;0 时的词汇量。最后，以非主导语言测量的触觉处理速度与抑制控制相关。这些结果提供了对年轻双语者词汇检索机制的见解，并扩展了先前关于触觉文字处理和词汇发展的研究。
