We taught 2 children with visual impairments to select a coin from an array using tactile cues after hearing its name and then to select a coin after hearing its value. Following the acquisition of these listener (receptive language) skills, we then observed the emergence of speaker (expressive language) skills without direct instruction.
我们教 2 名视障儿童在听到硬币的名称后,通过触觉线索从一组硬币中选出一枚,然后在听到硬币的价值后再选出一枚。在获得这些听众(接受性语言)技能后,我们没有直接指导,而是观察到说话者(表达性语言)技能的出现。
