Moral choice of people with exchange orientation relationship

Data from the experimental study. The level of exchange orientation relationship was determined using the Exchange Orientation Scale proposed by Clark and Mills (2012). The scale and its measures have been developed by the Clark Relationship Science Laboratory. The evidence for its validity is descibed in original source (Clark & Mills, 1993). The data were collected during study visits to universities in Spain (Madrid), the Netherlands (Amsterdam, Groningen, Rotterdam), and Poland (Bydgoszcz, Gdansk, Sopot, Torun, Warsaw).
