Have a look at Perfume adverts on TV: they are literally entirely made up of imagery meant to make one think about sex and being sexy, with not a single thing in any of them about the actual quality of the product.

Car adverts too are similar, but their imagery is about things like Freedom, Family, Friendship, Party, Joy and so on (depending on the car). Almost none of them talks about the qualities of the actual vehicle.

Adverts not relying in this kind of psychological manipulation are the ones which look a lot like 1950s adverts and talk about the actual qualities of the product.

Under-investment into training advertising creatieves doesn’t mean that the adverts aren’t using Psychology tricks anymore because that way of doing adverts is now so widespread and common in the industry (because it works!) that people just learn those things as tricks of the trade rather than needing any kind of special extra training in Psychology.
