Remember when you were young how happy you get when you hear the sound of the ice cream you want it badly, you cry, throw tantrums until your parents out caretaker gets it for you, even when you don't physically hear the sound of the van you think about it and wait for it badly. but as you mature you get wiser and more responsible that the sound of the ice cream van doesn't move you anymore, you Don't think about it that much, you get ice cream for fun and when you want to, you are now disciplined about it, but there are some adults who never overcome that and are still today influenced by the sound of the ice cream van.
Same way sounds can make someone an irresponsible gambler if they don't caution themselves. The Slot machine has lots of sounds that can get stuck in your mind especially the sound it makes when you win. There is this story about a man who is trying to be a responsible gambler on how he used to go to bed thinking about that winning sounds that comes from the slot machine, he just can't wait to be live facing the slot machine and anytime he is not facing the machine the sounds still lingers in his mind. The first step to his recovery was how he started to handle the slot machine sounds.
I think that this is the perfect example of what conditioning is. These sounds are associated with an end result most likely winning which then triggers a response in your brain and makes you more addicted or excited to hear that sound again, It’s hard to prevent exactly because it’s all happening psychologically
