Dorothy Bishop gave a lecture on the difficulty of agreeing on definitions and terminology for children's language disorders. She discussed how different disciplines and countries use varying definitions and labels for conditions like specific language impairment. Bishop highlighted research she has conducted using the CATALISE project, a multinational Delphi consensus study, to try to establish common terminology through an expert review process. However, she noted there are still sticking points in reaching full agreement across all perspectives.
