The science of craving

Pleasure and desire

One of the key things in pleasure is that it comes in cycles. 

The hungry desire state before a meal could produce pleasure from the anticipation of good food. Then, while eating, pleasure dominates, but desire could still come for more salt or a drink until satisfied. If we switch to the desert, we can prolong the pleasure again.




A new disorder

The World Health Organization officially added a new disorder to the section on substance use and addictive behaviors :

The term "addiction"

Addiction can include:

  • Addiction as a moral transgression, like excessive drinking or drug use.
  • Addiction as a scientific disease, which characterize alcoholism and drug addiction as biological.
  • Colloquial violation, which applies the term to almost any fixation. 

The idea that someone can be addicted to a behavior, as opposed to a substance, remains debatable.

Arguments against gaming addiction
  • Excessive gameplay is a symptom of a larger problem, like anxiety or depression.
  • The fear of possible addiction arrises from moral panic about new technologies, not scientific research or clinical data.
  • Making excessive gaming a disorder can harm the gaming industry by stigmatizing their products. 
The first views on motivation
The first views on motivation
  • At first, psychologist William James thought that only the initial act was conscious, thereafter behaviour was a spontaneous cascade of habits. He suggested we struggle with motivation when ...
Mathematics of motivation

When Ivan Pavlov and his dogs led to the discovery of learned behaviour through repeated exposure, and Edward Thorndike discovered the Law of Effect that stated that rewarded behaviours tended to increase, many psychologists were impelled to separate psychology from armchair introspection and formulated their theories as mathematical formulas.

  • The Drive x Habit Theory. Clark Hull's formula was sEr = D x sHr, which states that excitatory tendency (E) is the result of the drive (D) combined with the habit (H). The drive is nonspecific, such as hunger or thirst. The habit, however, depends on the stimulus (s) and response (r). But the theory turned out to be wrong and even opposite in many cases. 
  • Expectation x Value Theory. Drawing on ideas in economics and game theory, Edward Tolman and Kurt Lewis formulated an alternative account by evaluating motivation based on expectations. Tolman expressed the ideas as the mathematical formula: Subjective Expected Utility = Probability1 * Utility1 + P2U2 + P3U3 + … where subjective expected utility of an action equalled the motivation to act. But, if you expect a reward, why act and not simply passively wait for the expected reward? 
Motivation as change

Donald Hebb realised that existing theories were too focused on reacting to the immediate environment. Thoughts, ideas and goals could be just as strong for triggering action as sights and sounds.

Together with John Atkinson, they noted that the study of motivation had undergone a "paradigm shift", where motivation couldn't be seen as how actions get started, but how the organism decides to change its behaviour from one thing to another.

Rewards and dopamine
Rewards and dopamine

Our brains compute 3 things about reward: how much will we get, how soon will we get it, and how certain are we that we will in fact get it. 

And it’s when the probability of a re...

Why video games are so addictive

Games are enticing because you might win but you might not. And video games do it so efficiently, because they ride the tide of computer technology. The balance between winning and losing is continuously adjusted, according to how well you’re doing, as measured in hits and misses, gains and losses, moment by moment. The sweet spot knows you, it finds you. It adjusts to you.
