The present analysis repeated the aforementioned process however, users in addition to known their relationship to anyone at each Letter-value tested

The greater number of Letter try, in these previous knowledge, the fresh less overall professionals was in fact fundamentally prepared to forgo at the crossover point. Formula step one, a great hyperbolic dismiss purpose of an equivalent function since the decelerate and you may opportunities dismiss features (Eco-friendly & Myerson, 2004; Jones & Rachlin, 2006; Rachlin & Jones, 2008) revealed the results:

where V = the undiscounted reward value; v = the crossover point; ksocietal = a constant that varied across individuals. The greater was a person’s ksocial, the steeper the discount function, the lower the crossover points across the range of N’s, the less altruistic that person was.

Materials and methods

The aforementioned procedure is actually repeated that have 206 Stony Brook undergraduates but, after each crossover area try gotten, players indicated people-N’s relationship to her or him.

Next experiment requires one to imagine that you have made a summary of the fresh one hundred people closest for you from the business between the dearest friend or relative from the condition #step 1 in order to a mere friend on #100. Anyone on number one might possibly be someone you know well and that’s your best friend or relative. The person on #one hundred would be someone you realize and you can find but perhaps you age.

After that you might be asked to respond to a few inquiries regarding one within a given societal distance. Per web page, imagine the person that best suits the position (#1 so you’re able to #100) and you can answer per question.
