This paper reports an experimental investigation of the hypothesis tha
t in coordination games, players draw on shared concepts of salience t
o identify 'focal points' on which they can coordinate. The experiment
involves games in which equilibria can be distinguished from one anot
her only in terms of the way strategies are labelled. The games are de
signed to test a number of specific hypotheses about the determinants
of salience. These hypotheses are generally confirmed by the results o
f the experiment.
