Originally published in 1979, the world's leading researchers contributed chapters describing their work on the orienting reflex in humans. The contributions, at the time current and comprehensive, in a sense that each facet of contemporary research was represented, address the orienting reflex, now recognized as a fundamental component of human learning and cognitive function. The authors contributing to this volume emphasize both theoretical and methodological issues, as well as present more empirical research. Here is a volume that spans all current work on the orienting reflex in humans, both basic and applied, from the laboratory as well as clinical data, and which would be of immense interest to psychologists, psychophysiologists, psychiatrists, physiologists, and all others interested in this fascinating topic.
