Originally published in 1982, about 50 years after the publication of Lashley’s Brain Mechanisms and Intelligence. The aim of this book was to review Lashley’s major contributions and to trace the development of physiological psychology through the experimental work of Lashley’s students and colleagues and those influenced by Lashley’s writings. The contributors were invited to review their own experimental work in a lecture and to indicate how Lashley’s seminal contributions might have exerted an influence in shaping or directing their thinking. This volume is the result of their efforts.
