There are three types of motivation:

  1. Apparently spontaneous or automatic motivation stemming from the activation of the relevant schema (belief).
  2. A conscious, deliberate motivation emanating from a superordinate schema that has to do with the morality and/or appropriateness of the automatic motivation.
  3. The suppressing motivation draws on resources (see below) and is likely to be deficient and unsuccessful when the resources are depleted (Baumeister, Trice & Vohs, 2018)
  4. Amotivation: The individual lacks the motivation to do anything. This seems to be based on the perception of low resources such as during an episode of negative symptoms or when sick with an infection.
  5. The automatic motivation appears to be linked with the availability of dopamine since the region of the cortex associated with negative symptoms appears to be abnormally low in dopamine.
  6. Baumeister’s theory of Glucose may be as follows: The availability of glucose forms the substance for conscious, deliberate motivation such as is needed to generate constructive motivation or to suppress the automatic motivations (impulse control).
