There is neuroscientific evidence that people consider future versions of themselves as other people. As a result, intertemporal choice should refer to the interaction between multiple selves. We combine this notion of multiple selves in delay discounting with the approach for otherregarding preferences known as Social Value Orientation. The Social Value Orientation is a psychologically richer framework that generalizes the economic assumption of narrow selfinterest. People are assumed to vary in their motivations toward resource allocation between them and the others. When making such allocation decisions they may still be individualistic, but can also be competitive, prosocial, or even altruistic. We apply an experimental measure of impatience to a sample of 437 undergraduates, measure their Social Value Orientation, and collect selected demographic variables: gender, age, handedness, parenthood, religiousness, and current emotional state. We find prosocial participants to be more patient. Those who care for the others in the present also take better care of themselves in the future. We also find a participant's age and handedness to matter for his or her Social Value Orientation.

We administrate the cognitive reflection test devised by Frederick to a sample of 483 undergraduates and discriminate the sample to consider selected demographic characteristics. For the sake of robustness, we take two extra versions that present cues for removing the automatic (but wrong) answers suggested by the test. We find a participant's gender and religious attitude to matter for the test performance on the three versions. Males score significantly higher than females, and so do atheists of either gender. While the former result replicates a previous finding that is now reasonably well established, the latter is new. The fact that atheists score higher agrees with the literature showing that belief is an automatic manifestation of the mind and its default mode. Disbelieving seems to require deliberative cognitive ability. Such results are verified by an extra sample of 81 participants using Google Docs questionnaires via the Internet.

Undergraduates were given a battery of psychological tests to gauge their degree of antisocial personality traits (psychopathy, Machiavellianism and nihilism). The students also responded to questionnaires to assess their attitudes toward risk and 88Sergio Da Silva intertemporal choice. Biological attributes of the respondents were also collected. We found a correlation between psychopathic, Machiavellian and nihilistic traits in the sample, and also that risk seekers were antisocial. Additionally, we found, on average, that younger subjects presented higher levels of psychopathy; atheists were more Machiavellian; and atheists who were anxious tend to be nihilists. Moreover, boys born from younger mothers were more risk seeking than girls born from older mothers. We also found older subjects to be less patient.
