Social-value orientations in interdependence situations are expected t
o be influenced by self-presentational concerns because in contrast to
proself orientations (individualism and competition), prosocial orien
tations (cooperation, altruism, equality, and maximin) tend to make a
more positive impression on others. In the present study, the influenc
e of self-presentation on social orientation was inhibited by means of
a bogus pipeline procedure. Dutch University students in a bogus pipe
line condition displayed less prosocial and more proself orientations
than students in a condition in which no bogus pipeline was used.
