Drive reduction theory (learning theory)
Motivational readiness

An expansion on the drive-incentive link, developed by Warden, states that an individual's physiological needs will be coupled with a proportionate drive. Affordances are the available resources present in an individual's environment; these would be at their disposal to use to obtain their desired end-state. The individual's environment, in which the affordances are located, is similar to Lewin's living space. The level of effectiveness and affordance depends on what the want is. The affordance properties need to be able to suit the characteristics needed for the want to be fulfilled. For example, an individual whose want is shelter from a hail storm would not be satisfied if the affordance given was a miniature sized bag of gummy worms. Additionally, based on Warden's drive-incentive link, as either the drive or incentive increases, the behavior also increases. According to Hull, due to the interconnected properties of drive and motivation, in the presence of a drive, the discomfort of the individual increases; this discomfort gives them the motivation to dispel the need at the core of the drive.
