答案：D
根据文章最后一段第一句“...directed communication,when the communicator or sender,focuses the message for a specific audience”可知定向交流中，信息发送者所发送的信息传达给特定的听众，故A项正确，D项错误。本段第二句“One example is the way moms speak to their bahies”举出一个妈妈与婴儿说话的例子来说明定向交流，所以C项正确。文章中叙述了科学家研究发现雄性斑胸草雀特别为雌雀唱歌，最后科学家们指出这是一种定向交流，所以B项正确。故本题选D。
