Seventy-five male college students served as subjects in 25 teams of three individuals per team. Each team manned a station in a unidirectional communications network. Criterion scores of per cent intelligibility Stations one and two and total word reception Stations two and three were obtained using multiple-choice intelligibility tests. Various portions of the test were filtered into five different frequency band widths. The selected filtering conditions acted upon the multiplechoice verbal material in a manner comparable to other types of speech tests, differentially affecting the magnitude of information loss usually found when a message is relayed. There was no evidence found for a decrement in total number of words transmitted per unit time due to selective filtering or retransmission. Author
