Originally published in 1981, this volume represents the edited proceedings of the third symposium on eye movements and behaviour sponsored by the US Army Human Engineering Laboratory. The conference, titled The Last Whole Earth Eye Movement Conference was held in Florida in February 1980. As the conference approached, seizure of the American hostages by the Iranian militants, the Russian invasion of Afghanistan, and the uncertain economic outlook around the world made it appear as though the title was a self-fulfilling prophecy. But the meeting proved highly successful and people throughout the world seemed to be adapting to the stresses of international tension, making the possibility of subsequent meetings more likely. The present volume is intended to serve as a complementary text to the earlier texts Eye Movements and Psychological Processes (Monty & Senders, 1976) and Eye Movements and the Higher Psychological Functions (Senders, Fisher & Monty, 1978), rather than a revision and update of them.
