Michael Eysenck

Michael William Eysenck (Born 1944) is a British psychologist and currently a Professor in the Psychology department of Royal Holloway, University of London. His research focusses on cognitive factors affecting anxiety. Eysenck has authored and co-authored numerous publications, including several textbooks. In the late 1990s, he conceptualised the theory of the 'Hedonic treadmill', stating that humans are predisposed by genetics to plateau at a certain level of happiness, and that the occurrence of novel happy events merely elevates this level temporarily.

He is the son of the noted psychologist Hans Jürgen Eysenck.
