In this chapter, we review classical theories on hedonic adaptation: adaptation-level theory, range-frequency theory, hedonic relativism and the hedonic treadmill, opponent-process theory, the concept of the genetically determined set point, the distinction between desensitization and shifts in adaptation levels, and dynamic equilibrium theory.

This baseline level is sometimes referred to as the set point for SWB and is assumed to be primarily determined by heritable factors. Classical theories of hedonic adaptation assume that lasting changes in subjective well-being (SWB) are not possible because one’s SWB inevitably returns to its baseline level, a phenomenon known as the hedonic treadmill.
