【解析】本句话是由冒号连接的两个并列分句构成。分句1中，a mother是主语，is asked to interact with是谓语，her child是宾语，in a normal way是状语， before putting on a blank expression and not giving them any visual social feedback是时间状语。分句2中，the child是主语，becomes是系动词，increasingly distressed是表语，as she tries to capture her mother’s attention是时间状语从句。
【译文】在实验中，母亲被要求先以正常方式与孩子交流，之后摆出一副面无表情的神情并且不给孩子任何视觉上的社交反馈;孩子在试图吸引母亲注意力的过程中变得越来越苦恼。
