Dopamine seeking behavior

There are very few articles about this in the lay press, unfortunately. The very few ones:

• "The Dopamine Seeking-Reward Loop", published by psychologytoday.com, written by Susan Weinschenk Ph.D.
• "Why Can't I Stop Scrolling On My App Feeds?", available on YouTube.com, created by Dr. Susan Weinschenk

The material seems to suggest a couple things:

• There may be an explanation for why one tends to endlessly scroll social media or other news sites, why you always feel the urge to do "just one more click".
• Dopamine may play a big part in this. [2] [3] [4]
• There are circuits in the brain that encourage "seeking" behavior:
  • "Dopamine causes you to want, desire, seek out, and search. It increases your general level of arousal and your goal-directed behavior. Dopamine makes you curious about ideas and fuels your searching for information."
• "It's not the reward itself that keeps the dopamine loop going; it's the anticipation of the reward. Robert Sapolsky talks about this anticipation/dopamine connection in his research."
• Dr. Susan Weinschenk suggests a way to stop the neverending-scrolling loop — create a new conditioned response, a physical movement, that you do to sort of signal to the brain that "this is done".

This article suggests ways to "hack" your dopamine system to encourage productivity: 1) Record small accomplishments, 2) Share results with your team, 3) Stay on task with micro-deadlines, and 4) Focus on how great you’ll feel when your project is complete.

There IS a lot of recent academic literature [2] about this, but I'm not qualified to judge their merits. Therefore, I'm really interested in credible science communicators who publish accessible summaries in the lay press.
