Delay discounting for rodents: do you want 1 sucrose pellet now, or 4 sucrose pellets in 40s?
Delay discounting for toddlers: do you want 1 marshmallow now, or 2 marshmallows in 15 min?
Delay discounting for adults: do you want $100 now, or $1000 at the end of the month?
Delay discounting for prospective first-time home buyers: do you want to buy this kind of nice house now (provided nobody else has bought it before you decided to make an appointment to go see it) or wait whether a nicer house comes by - with more space, in a nicer location, etc etc-, not knowing whether the nicer house will actually show up, or whether the interest rate on mortgages, which is really low now, will still be low then. Or wait five more years in the very comfortable rental place that you are in now so that you will have more spendable income (provided you both will keep your jobs) and buy an even more expensive and nicer house then (but what will happen to the interest rates in 5 years?!).
How on earth do people make decisions about buying a house? But then again, how do rats decide between rewards... can someone measure my dopamine?
