在之前的一项研究中，学龄前儿童在解决维度变化卡片分类任务中的双语优势归因于注意力抑制的优势（Bialystok，1999）。然而，该任务包括编码和解释任务刺激的困难表征要求，双语者也可能受益于卓越的表征能力。三项研究检验了这种可能性。在研究 1 中，双语者在包含中等代表性要求的问题版本上优于单语者，但在要求更高的条件下则不然。研究 2 和 3 表明，当目标维度是刺激的感知特征时，双语儿童比单语儿童的技能更高，而当目标维度是语义特征时，两组儿童的技能是相当的。结论是，双语者比单语者对忽略感知信息有更好的抑制控制，但在表征方面并不更熟练，这证实了最初研究的结果。结果还表明，忽略过时的显示功能的能力是解决此任务的关键困难。
In a previous study, a bilingual advantage for preschool children in solving the dimensional change card sort task was attributed to superiority in inhibition of attention (Bialystok, 1999). However, the task includes difficult representational demands to encode and interpret the task stimuli, and bilinguals may also have profited from superior representational abilities. This possibility is examined in three studies. In Study 1, bilinguals outperformed monolinguals on versions of the problem containing moderate representational demands but not on a more demanding condition. Studies 2 and 3 demonstrated that bilingual children were more skilled than monolinguals when the target dimensions were perceptual features of the stimulus and that the two groups were equivalent when the target dimensions were semantic features. The conclusions are that bilinguals have better inhibitory control for ignoring perceptual information than monolinguals do but are not more skilled in representation, confirming the results of the original study. The results also identify the ability to ignore an obsolete display feature as the critical difficulty in solving this task.
