in the lecture the professor talks about social referencing which means babies can gradually understand new environments and learn to respond to them.they make decisions based on reference from the circumstances
in the first example,6 month old babies were seperated in two groups .the first group were asked to play dolls while their mum were smiling.the mums in second group were asked to frowned.the babies played dolls regardless of whether their mums smiled or frowned.the result shows that 6 month babies had no response to their mum's facial expressions they are too young to understand and respond the environment
in the second example,1 year old babies were asked to do the same thing they played dolls immediately if their moms smiled or refused to play if their mums frowned.the result shows that 1 year old babies had response to their mum's facial expressions
先说定义,在描述实验,把实验过程阐述一下 注意要说出结论
再问： 太谢谢了！
