 At the Institute, Zuckerman undertook research into anxiety and sensory deprivation (funded by NIMH grants) which ultimately led him to develop his well known Sensation Seeking Scale.Subsequently, in 1969, he accepted an academic position in the Department of Psychology at the University of Delaware, where he spent more than 30 years teaching and undertaking research into sensation seeking and personality.His biochemical, psychophysiological and genetic studies demonstrated that sensation seeking was a major biologically-based trait construct.
