I was in a lecture recently on the subject of substance abuse and drug addiction. Specifically, on the way that dopamine is triggered by not just the use of drugs, but also cues associated with that drug. For example, returning to the same room you took the drug in, or being with the same people you took the drugs with. These cues are not exclusive to drugs but any addictive behaviour, such as gambling or on-line gaming.
I was reading the newspaper and as I finished, I noticed the advert on the back page – Bold blue background with a small letterbox picture of a couple, with the word ‘Friends’, written underneath. At the bottom of the page was the Facebook logo. Very odd, I thought, everyone knows about Facebook, why would they need to advertise?
