This table shows that the re- sponses of females to paired torch flashes involved the same order of delay as in dialogues with real males even though the intervals between the two torch flashes were in many instances well outside the range of intra-phrase intervals of actual males (extreme range among two males, to sees; among effective torch pairs to sees). 4.
